3 Weight Loss Truths

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

If you haven’t been bombarded with weight loss ads over the past week, you’re probably on a remote island soaking up the sun with the waves gently teasing your feet (bring me next time). There’s something about the start of a New Year that makes people freak out, lose their senses and develop completely unrealistic eating plans they will never follow for more than a few days. Before you get sucked into a crazy diet or juice cleanse, you should know the top three truths about weight loss.


1) No One Eats “Clean” all of the Time

Instagram and Facebook are full of photos of broccoli, brown rice and chicken meals neatly placed in Tupperware and followed by #mealprep #eatclean. The only thing more boring than looking at these meals is eating them day after day. No one eats like this all of the time. No one.
I’ve worked with a number of elite athletes who cut weight before a fight, match or event. They diet down, compete then loosen up their diet a bit before they need to diet down again. They aren’t eating bodybuilding-type meals every day year-round.

2) There is No One Perfect Diet

Jenny Craig, Weight Watchers, juice cleanses, Paleo, Whole30. There is no “perfect” because what’s right for you isn’t necessarily right for me. Figure out what changes you can realistically stick with, combine these with the general principles of healthy eating and start there. Forget what everyone else is doing, how your neighbor dropped 50 lbs. or what the actress on the cover of a magazine did. If you can’t stick with a plan, it won’t work.

Progress, not perfection, is the goal.

Celebrate each “win,” those small changes you’ve made that will add up to a big difference. You won’t necessarily notice a weight loss right away by making a few simple switches in your diet. However, I would rather people focus on the immediate difference – more energy, feeling better, more sleep, than the number on the scale. Feeling better each day will drive you to continue when the scale isn’t moving much.

3) You Must Exercise for Weight Loss

Can you lose weight without exercising? Yes absolutely. However, if you do not exercise you will lose more of your weight as muscle then fat. In addition to burning fewer calories each day when you lose muscle, you will notice a decline in strength and as you get older and everyday activities will become harder to do – lifting groceries, gardening, washing your car.

If you are not an exerciser and typically fall off when you start a new workout program, figure out what you like to do and do it. Forget all of the back-and-forth “noise” about high intensity interval training, the amount of rest in between sets and if you should train until muscle failure (until you cannot possibly lift the weight again). Instead, determine what brings you joy. What do you love to do? Dancing, yoga, hiking? What did you love doing as a kid? Hula hooping, double Dutch jump rope?

Do what makes you happy. Get moving and stay moving.

In addition to following these weight-loss truths, spend time feeling good about your body every single day. I meet so many people that are hyper focused on losing 5 pounds or 50 lbs. As they rattle off the reasons why they want to lose body fat and how this will drastically alter their life and make them happy, my mind often drifts off. I wonder what percentage of their thoughts are consumed by losing weight and dieting and if they are hyper-focused on controlling this aspect of their life because something else isn’t right. A marriage, their job, a friendship, their child’s behavior. If I ask the right questions something else they are ignoring often comes up.

Maintaining weight within a good range is very important for overall health. Obsessing about weight and dieting isn’t. I’ve coached enough people to know that one day you’ll look back years from now and wonder why you wasted so much time hating your body.

You’ll look back and say, “damn, I looked good! I wish I felt better about myself.”

“I wish I wore shorts in the summer.”

“Why didn’t I go to the beach in a bathing suit?”

“I wish I went to that party.”

I promise you, no one is criticizing your body. Every one around you is too busy focused on themselves. So go out and wear shorts, put on a bathing suit, try on that dress.

If you don’t love your body now, you won’t feel your best every day. You won’t enjoy life to the fullest. Work in this first (or in conjunction with healthy eating / a healthy approach to weight loss).

Because it’s a waste of time to spend your days bashing the body that does so much for you.

Is TMAO from Fish, Meat and Eggs Harmful?

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

In another confusing nutrition story that should be titled “is there anything left for us to eat?” recent research threw a curveball. Fish, a staple of the Mediterranean diet, as well as meat and eggs may be doing more harm than good thanks to a compound called trimethylamine-N-oxide (TMAO). TMAO is found in fish and produced in the body after eating meat and eggs. TMAO is linked to greater risk for heart attack, stroke and death; yet the research isn’t crystal clear. Is it time to give up fish meat and eggs or ignore the recent media headlines?

This post will cover:

  • TMAO: More than a Gut Reaction—What gives us higher TMAO levels?
  • TMAO and health?
  • The bottom line

TMAO: More than a Gut Reaction

Blood levels of TMAO are ~ 50 times higher after eating fish compared to eggs or beef. The human body absorbs intact TMAO like the kind found in fish, easily. However, the human body’s production of TMAO, after eating foods containing the essential nutrient choline (found in eggs and meat) and the compound l-carnitine (found in meat and pork and in much smaller quantities in chicken breast and dairy products), depends on the makeup of bacteria in your gut, kidney functioning and genetics.

In one study, regular meat eaters produced more TMAO than a vegetarian did after eating steak (which contains ~ 180 mg of l-carnitine). After wiping out their gut bacteria with antibiotics, the carnivores didn’t produce any TMAO after consuming 250 mg l-carnitine. The makeup of gut bacteria in the habitual meat eaters was presumably responsible for greater TMAO production compared to the vegetarian, yet this was a small study and we don’t know anything else about the participants’ diet. Was it the meat that altered gut bacteria or something else in their diet? After all, a steady diet of red meat may mean double cheeseburgers on white bread with regular servings of French fries and soda on the side. This isn’t exactly the diet you want for promoting good bacteria in your gut.

Another study found blood levels of TMAO were greater in those with a less diverse makeup of microbes and greater amounts of a less healthy type of bacteria (firmicutes), compared to one that is healthy (bacteroidetes). A diet higher in saturated fat will promote this environment.

While bacteria seem to influence TMAO production from l-carnitine, l-carnitine also influences the makeup of gut bacteria. A study in mice found those with their gut bacteria wiped out thanks to antibiotics produced a different makeup of bacteria in the gut after consuming l-carnitine while also doubling the risk of plaque buildup in their arteries.

Higher TMAO levels come from:

  • Eating fish
  • Less diverse array of gut bacteria and increased levels of bad versus good bacteria
  • Consuming l-carnitine (mouse study)

TMAO and Health

A few human studies found higher blood levels of TMAO were associated with greater risk for heart disease. However, all research isn’t pointing in the same direction. One study in over 300 patients found blood TMAO levels were not associated with heart attack or heart disease over the course of eight years, following the initial test for TMAO. However, TMAO levels were higher in those with diabetes, patients with metabolic syndrome and those with declining kidney functioning. Another study examined over 800 people between the age of 33 and 55 and found blood TMAO levels were not associated with clogged arteries, insulin resistance (this comes before type 2 diabetes) and inflammatory markers or negative changes in blood lipids suggesting TMAO levels might not contribute significantly to the progression of clogged arteries. However, this study shows TMAO levels were significantly lower than in previous research, showing an association between TMAO and heart disease.

TMAO is considered a risk factor for cardiovascular disease. In those with type 2 diabetes, higher TMAO levels are associated with greater risk for death, heart attack, heart failure and unstable angina (chest pain). Also, higher levels of circulating TMAO are associated with higher risk of death in those with chronic kidney disease and greater risk of certain cancers. Yet, there are several confounding factors. Fish is the primary culprit for higher acute circulating TMAO levels, yet fish-based diets are associated with reduced risk for heart disease. Also, levels of TMAO are dependent upon disease state and the makeup of gut bacteria. Therefore, at this time it isn’t entirely clear which came first – does TMAO cause disease or does TMAO increase due to disease?

The Bottom Line

The story on TMAO isn’t crystal clear, so there’s no reason to avoid fish, meat and eggs in an effort to decrease TMAO levels. All three of these foods are good sources of several nutrients important for health. Though processed red meats are linked to higher risk of colorectal and stomach cancers, when cooked appropriately (lower, moist heat for example) red meat can fit into a healthy diet and deliver important nutrients including iron, zinc and vitamin B12. Eggs are an economical source of protein and contain many nutrients and compounds that contribute to health including two antioxidants important for eyesight.

Though there is no reason to completely avoid these foods, you can alter your diet to help diversify gut bacteria and also increase the amount of good versus bad bacteria. Probiotic rich foods such as yogurt and kefir with live and active cultures, miso soup, tempeh and other fermented foods contain good bacteria. Fiber-rich plant foods (fruits, vegetables, legumes) are important food sources for bacteria to thrive in your body.

What You Need to Know about Pork

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

If visions of mistreated animals injected with a continuous supply of hormones and antibiotics leave you feeling confused and terrified about your food choices—this post is for you. I’m cutting through many myths about how pork is produced, so you can rest assured you are making the right choices. For this post I interviewed Wanda Patsche, a pig farmer from Minnesota.

Aren’t big farms owned by big agriculture companies?
Wanda: Family farmers own 97% of pig farms. Some farms are big some are small.

What are the greatest misperceptions consumers have about pigs?
Wanda: Many people think modern farms are less humane compared to small farms; niche farms, pasture raised. Actually, the opposite is true. With modern farms barns are designed so you can handle the pigs better; pigs have a social hierarchy where they fight with each other. Modern farms are specifically created to easily control this fighting by having pigs in individual pens. This means less stress for the pigs, plus the buildings are temperature controlled with fresh air. Pigs are given clean water and clean feed. The barns are pressure washed and sanitized between groups of pigs (when pigs move out and prior to new pigs coming in). Plus, pig farmers work closely with their veterinarians. Farms that have more pigs mean the famers continually grind feed because they have more mouths to feed. Continually grinding feed means the pigs get fresh feed. Their diets are designed for health and growth.

What you need to know about porkIs hormone-free pork better?
Wanda: No pigs are given hormones. Farmers are not allowed to give pigs hormones. Therefore, any pork labeled “hormone-free” has been given this label to try and make customers think it is better than other pork. However, there is no difference, all pork is free from added hormones.

Are there any antibiotics in my pork?
Wanda: Antibiotic-free is another labeling term to try to persuade customers to choose chose a specific pork product. All meat is free of antibiotics. If a pig is given an antibiotic, all traces of the antibiotic must leave the body—called the withdrawal period—before the pig is sent to off for pork production.

What do you think is driving these perceptions?
Wanda: In the U.S., less than 2% of people are farmers. Many people don’t know farmers, and they are 2 – 4 generations removed from farmers. If you’ve never been to a farm or know people who farm it is easier to believe the myths that circulate on the internet.

Tell us a little more about advances in pork production and the safeguards in place to ensure pork is safe.
Wanda: Forty years ago, pigs were all outside. They had clean air but many hazards including sunburn and the greater likelihood of getting worms (and therefore the vets would have to treat them with medicine for worms). Now, with the introduction of indoor facilities and individual pins, pigs are less stressed which keeps them healthier. Stress = greater likelihood of sickness.

In addition, antibiotics are used less, and there is a comprehensive vaccination program in place to keep pigs healthy. On farms that do not use antibiotics to treat animals when sick, the animals must be pulled away from the other pigs to prevent the illness from spreading.

Animal scientists are currently conducting studies examining ways to keep animals healthy including the use of essential oils, probiotics, and enzymes. Healthier pigs mean even fewer antibiotics are used.

Antibiotics are the last resort and only used when necessary.

Pigs are grouped together based on age. This is helpful as immune system functioning differs by age. This is just another step to keep pigs as healthy as possible.

Aren’t farms more concerned about quantity vs. quality?
Wanda: No. Every day I wake up and think, “what can I do to ensure my pigs are as healthy as possible?” Pig farmers get more money for higher quality meat. So, every pig farmer has an added incentive to produce healthy, high quality pigs. Lower quality pork goes to a secondary market for ground pork, pepperoni and similar process products. Farmers get considerably less money for lower quality pork.

Are there any concerns that consumers should have about pork?
Wanda: The biggest concern for consumers is how pork is handled and cooked. According to the USDA pork should be cooked to 145°F internally. Ground pork should be cooked to 160°F. It can be pink in the middle as long as these internal temperatures are reached.

What are the best cuts of pork?
Wanda: pork is 16% leaner than it was 20 years ago due to the way animals are fed and genetics. Pork tenderloin is just as lean as chicken breast. An easy way to remember this: loin = lean.

The Truth about Cage-free, Free-range, No Antibiotics, Humanely Raised

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

Nutrition claims are confusing. How do you know if you should pay more for a carton of eggs or package of meat based on a claim on the package? Is it legit, or made up by a marketing team to make their food stand out from competitive products on grocery store shelves? This post will help you sort through the confusion on common food claims including cage-free, free-range, antibiotic-free and differences in egg quality scores so you can choose which option is best for you.


free-range, cage-free eggs

Eggs: Cage-Free, Free-Range & AA, A and B Quality

Cage-free (eggs) – “cage-free” refers to the environment the hens (hens lay eggs) live in. Cage-free hens are housed in an environment allowing unlimited access to food, water and freedom to roam. There is no known nutrition difference in eggs produced by hens that are cage-free versus those that are not cage-free1.

AA quality eggs – the shells must be “clean, unbroken and practically normal.” Also, the white must be clear and reasonably firm, with a clear distinction between white and yolk. The yolk must be free from apparent defects. The air cell—the part of the egg that separates the inner shell membrane from the outer shell membrane—for AA quality eggs must not exceed 1/8 inch2.

A quality eggs – the only difference between AA and A quality eggs is the air cell. The air cell for A quality eggs must not exceed 3/16 of an inch2.

B quality eggs – the shells must be unbroken, but may be abnormal or have slightly stained areas. Shells with prominent stains or dirt are not permitted. The egg white can be weak and watery, while the yoke may be dark and large and flattened. Small blood or meat spots may be present2.

Meat and Dairy Claims

Pasture-raised, free-range, free-roaming – the animals have continuous, unrestricted access to pasture (land covered with grass and other plants) throughout their lives. Cattle and sheep must not be confined to a feedlot. Pigs must have continuous access to pasture for at least 80% of their life. You might see “free-range – never confined to feedlot,” on your meat3.

Antibiotic-free or No Antibiotics – all meat, milk and other dairy products are free from antibiotics. Therefore, a package of meat that says “antibiotic-free” is no different from the one next to it that does not carry this claim. When an animal is on antibiotics, their milk is not sold, and they cannot be slaughtered for meat. Instead, the farmer must wait until all traces of medication have cleared the animal’s body before the cow can be milked or the animal can be sent for slaughter. For more on this topic as related to milk, click here.

Humanely raised – this term makes me think of a farmer who knows each animal by name; pets and cares for them daily while attending to their needs. However, this isn’t the case. “Humanely raised” is a term made up by food companies. There is no formal definition and therefore, it is up to the food company to decide what they consider humanely raised. Ignore it. 

Naturally raised – there is no official definition for naturally raised. Therefore, this claim could mean anything. Ignore it.

Grass-fed – there is no universally accepted, standardized definition for the term grass-fed. All cows, sheep and goats eat grass for most of their lives. However, some of these animals are grain-finished—they spend several months on a grain-based diet until they reach their ideal weight. At this time, their diet consists of grains, grass, vitamin and mineral mixes, citrus pulp and other feed as determined by an animal nutritionist based on their dietary needs. Other animals are grass-finished, they consume grass their entire life, and may be given vitamin and mineral mixes as needed. There are no nutrition differences between grain-finished and grass-finished meat.

Food is a very competitive business. Consumers may choose a product based on a variety of factors including great packaging, superior taste and good nutrition value. Food claims may sway your decision; however, be sure you’re getting what you are paying for. Look for claims that are backed by a standardized definition, versus those with no definition.

Slow Digesting Carbohydrates for Fat Loss and Better Performance?

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

Consume fewer calories, use more body fat and feel great during exercise – these are the claims behind slow digesting carbohydrates. Before you ditch your typical sports drink in favor of a slow digesting carbohydrate, check out the truth behind each of these lofty claims.

In this post I will cover:

  • One big fat myth – slow digesting carbohydrates won’t help you burn body fat
  • Trying to burn fat during exercise is pointless
  • Fast carbohydrates are better for high-intensity athletes
  • Advice for those on a low carbohydrate diet

According to Generation UCAN, makers of a slow digesting starch (a type of carbohydrate), typical high sugar sports nutrition products cause a rapid increase in energy followed by low blood sugar leading to a sharp crash, leaving you feeling tired with a bad case of the munchies (“post-workout cravings” according to their website). Generation UCAN’s starch will keep your blood sugar levels nice and steady while delivering long-lasting energy for hard-working muscles. The payoff? You need fewer carbohydrates (and therefore calories) to fuel activity and your insulin levels (a hormone that helps store body fat among other functions) are kept low so your body can pull from a larger supply of body fat (multiple times larger than the amount of carbohydrate stored in muscle and liver).

All of this sounds great in theory. Yet none of it holds up in real life.

Typical sports nutrition products do not cause a sharp crash (symptoms of low blood sugar) when consumed before or during exercise (1). Instead, your body will use the sugar pretty quickly to fuel hard working muscles (2). What about post-workout cravings? Typical sports drinks, gels and gummies won’t lead to cravings, despite possible changes in blood sugar, even if you consume them when your body doesn’t need them – when you are sitting on the couch scrolling through Snapchat videos (3).

One Big Fat Myth – Slow Digesting Carbohydrates Won’t Help You Lose Body Fat

Trying to burn fat during exercise is pointless (unless you are a ultra distance athlete and therefore relying on large amounts of fat for energy to run for several hours at a time). Otherwise it doesn’t matter if more fat is used during exercise. What matters most if you want to lose weight? The total amount of calories burned over time.

You are better off burning fat while sitting in front of your computer or sleeping then trying to maximize fat used during exercise. Why? Fat is a slow source of energy – if you are seriously tapping into your fat stores during exercise you aren’t exercising very hard and therefore you aren’t burning very many calories. If you want to make the most of your exercise sessions, burning as many calories as possible, you’ll need carbohydrates to help you sustain your exercise intensity. It’s the difference between walking and sprinting. You have to walk for a much longer period of time to burn as many calories as you will if you are sprinting or doing intervals.

Fast Carbohydrates are Better for Athletic Performance

slow digesting carbohydratesCarbohydrates are the best source of energy to keep up with the calorie demand of high-intensity exercise. The less carbohydrate you have stored in your muscle (stored from the carbohydrate you eat each day), the more your body will rely on carbohydrate consumed during exercise in the form of sports drinks, gels, beans, gummies etc. Fast carbohydrates (the mix of sugars in common sports nutrition products) have been successfully used for decades. Yet some athletes get an upset stomach when exercising. Generation UCAN says their product will lower risk of stomach upset. Unfortunately, a well-designed study found athletes actually had greater stomach upset on UCAN (a slow digesting carbohydrate) than they did on traditional sports nutrition drinks (8). If you don’t want the nitty-gritty science, skip the next section and move to the following paragraph.

In this crossover study (each study subject experienced each type of drink) 10 male cyclists consumed 1) 60 grams of carbohydrate from a typical sports nutrition drink (sucrose and glucose blend) 30 minutes before and 60 grams of carbohydrate per hour during exercise (Sports Drink); 2) 60 grams of carbohydrate from UCAN (hydrothermally-modified starch; HMS) before and 60 grams of carbohydrate per hour during exercise (Isocaloric HMS); 3) 60 grams of carbohydrate from UCAN before and 30 grams of carbohydrate per hour during exercise (Low HMS). They spent three hours exercising (one hour at a moderate pace followed by intervals and sprints). There was no difference in performance between the Sports Drink and High HMS. Both the Sports Drink and High HMS resulted in slightly better performance compared to Low HMS (less carbohydrate during exercise). Consuming UCAN, whether 30 or 60 grams per hour, led to greater incidence of nausea compared to consuming 60 grams of carbohydrate per hour from a typical Sports Drink (8).

Typical carbohydrates used in sports nutrition products are digested quickly and used by muscles right away so you can train harder than you would if you relied on slow carbohydrates. The body can use about 30 – 60 grams of carbohydrate per hour, and possibly up to 90 if a mix of different sugars is used. Fat metabolism kicks in after around 20 minutes of aerobic exercise. “After about two hours of continuous endurance exercise, fat is a major source of energy. However, carbohydrate is still essential. Without enough carbohydrate present there is incomplete burning of fatty acids resulting in ketone bodies as a byproduct. When ketones build up, the body’s pH drops (metabolic acidosis) and the body attempts to compensate via respiratory hyperventilation,” states sports dietitian Sally Hara, MS, RD, CSSD, CDE. You won’t improve performance if you consume slow carbohydrates before or during exercise (5).

Fast carbohydrates are also preferential right after exercise – your body can rapidly replenish carbohydrate stores in muscle for use during her next training session. This is very important for athletes who train more than once over the course of an 8-hour period and also important for those who train again less than 24 hours later (6, 7). Anyone who doesn’t train again less than 24 hours later can re-stock their carbohydrate in muscle by consuming enough carbohydrate in their diet from potatoes, rice, quinoa, and other higher carbohydrate foods.

You can function on fewer carbohydrates. However, “there is a difference between functioning and performing your best. Athletes and high-intensity sports to follow a low carbohydrate diet are more likely to get tired early and make mental errors,” states Hara. If you want to perform well and burn more calories while lowering risk of stomach upset, choose a traditional sports nutrition product instead of being swayed by the false marketing promises behind slow digesting carbohydrate products.

Get Cultured: Probiotics can Help You Lose Weight & Stay Healthy

From Greek to Icelandic Skyr, yogurt is everywhere. Choose the right kind, one packed with probiotics and protein, and yogurt can help you trim your waistline while supporting overall health at the same time.

In this article, I’m covering:
• How gut bacteria influence your weight and health
• Probiotic-rich foods for health & healthy weight

Your Gut Bacteria Influence Your Weight & Health

There is an entire community of over one trillion microbes (bacteria) taking up valuable real estate in your gut. Some are good, some are bad and the rest are neutral. The good guys are key players for digestive and immune functioning (remember about 70% of your immune system is located in your gut). They have many other functions as well:
bacteria, probiotics and body weight

Research studies show lean and obese people have a different makeup of bacteria in their gut. In addition, lean individuals have a greater diversity of bacteria in their gut. Diversity is important –  think of bacteria like a team of people each one has a different job and they work better together than in isolation.

If an obese person loses weight their overall makeup of bacteria more closely resemble’s a lean person’s gut. Greater weight loss = even greater the changes in gut bacteria. Also, changing bacteria seems to influence weight, though scientists know less about the influence of altering gut bacteria and changing body weight. Lean mice transplanted with bacteria from obese mice experienced a 60% increase in body fat without changing their food intake (calories in) or physical activity (calories out). The authors of this study believe the change in gut bacteria resulted in an increased absorption of some carbohydrates, increase in the production of fat and increase in fat storage. Authors from another study, this one examining human twins, also found a connection between types of bacteria in the gut and body weight, particularly visceral fat – deep layers of fat that coat the organs and are tied to higher risk of certain chronic diseases such as heart disease. The authors of this study believe, like the study in mice, obese individuals may be absorbing more calories from the food they eat.

Probiotic-Rich Foods for Health & Healthy Weight

How did they swap out bacteria in studies? Poop transplants. This isn’t exactly something you should try at home. But there’s another, easier way to keep your gut healthy. Get cultured by picking up foods that contain healthy bacteria including yogurt (with live and active cultures), kefir (drinkable yogurt, it’s so good!), miso soup, homemade sauerkraut, and tempeh (made from soy, this has a nutty taste). There might be something special about yogurt – a meta-analysis (a study that combined the results of other studies) looked at dairy intake and weight changes over time. They found greater yogurt intake was associated with lower body weight. Plus the protein in Greek yogurt seems to help people feel full so they eat less at their next meal. Also, feed the bacteria by eating plenty of fruits, vegetables and whole grains, particularly onions, greens, beans, legumes, berries and bananas, to get enough prebiotics (food) to support their growth.

Top 10 Flat Belly Foods

Your abs are made in the gym and revealed in the kitchen. A good training program develops the muscles in your midsection and the right diet helps banish bloating so you can see your abs. Here are the 10 flat belly foods you should add to your diet for a better looking (and better feeling) mid-section):Greek yogurt for belly fat

Greek Yogurt with Live and Active Cultures

Look for Greek yogurt with “live cultures (aka good bacteria)” or the “Live & Active Cultures” seal. The cultures are good bacteria that take up valuable real estate in your gut, helping your body digest food and decreasing gas and bloating. The amount of healthy, versus harmful, bacteria influences body weight and how much weight you can lose while following a lower calorie diet. Plus, a study published in the International Journal of Obesity found people who get their calcium from yogurt, as opposed to other foods, may lose more weight in their belly. Even more evidence to support yogurt consumption comes from a study showing dieters who ate five servings of dairy, such as Greek yogurt, daily lost more weight and abdominal fat than those who ate just three servings every day. A more recent review of the research found higher dairy intake was associated with lower risk of obesity in the midsection and yogurt seems to help keep weight in check.

2 Nuts

Though nuts are relatively high in calories for a small amount of food,  people don’t gain weight when they add nuts to their previously nut-free diet. A study in over 13,000 adults revealed nut eaters, those who ate at least ¼ ounce of nuts or peanuts (technically a legume) per day had smaller waists than adults who didn’t eat nuts. Additionally, tree nuts and peanuts contain a considerable amount of monounsaturated fat. Dieters who eat more foods containing monounsaturated fats may lose more belly fat than those who eat the same number of calories per day with less monounsaturated fat.

3 Asparagus

When examining dietary patterns, weight and waist circumference in close to eighty thousand people over a 10-year period, researchers found those who ate more vegetables every day had both a lower BMI and smaller waistline compared to adults who ate few vegetables. Asparagus contains prebiotic fiber, a type of fiber that is food for the good bacteria in your gut. Plus, asparagus is a natural mild diuretic making it the perfect food before hitting the beach or wearing a more formfitting outfit.

4 Avocados

Avocados contain a good amount of monounsaturated fat, not to mention nineteen vitamins and minerals. But, their monounsaturated fat is the ticket to a smaller waistline. In one study scientists gave obese adults with type 2 diabetes diets rich in saturated fat, monounsaturated fat or  carbohydrates. Those on the high carbohydrate diet ended up with fat redistributed to their stomachs while the monounsaturated fat rich diet prevented fat redistribution to the belly area. Plus, a look at dietary intake data from close to 18,000 adults found body weight, BMI and waist size were all significantly lower in avocado consumers versus those who didn’t include avocados in their diet.

5 Popcorn

Popcorn is a whole grain and when you pop it yourself on the stovetop (or in a brown paper bag in the microwave, just add good old fashioned popcorn kernels in a brown paper bag and fold the top) and top it with a little spray butter or spices for flavor, you’ll end up with a snack that takes a long time to eat and fills you up on relatively few calories. In addition, several studies show people who eat about three servings of whole grains per day weight less and have a smaller waistline compared to those who don’t.

6 Cold Pea Salad

Peas are naturally rich in resistant starch, a type of fiber that isn’t completely broken down or absorbed during digestion. Cooking and cooling peas to make a pea salad will significantly increase the amount of resistant starch they content. Rodent studies show resistant starch helps reduce stomach fat and increase hormones that tell the brain it’s time to stop eating.

7 Eggs

Choose eggs over cereal in the morning and you’ll tame hunger pangs for hours after breakfast, decreasing the likelihood of overeating later in the day. Make a meal containing at least 25 – 30 total grams of protein (the protein is in the white of the egg so this equates to 4 – 5 egg whites though you can choose any combination of whole eggs and egg whites as long as you consume at least 4 -5 of the whites) so you can cash in on the satiety-enhancing benefits of eggs. Added bonus: following a high protein diet for a short period of time can lead to significant reductions in belly fat.

8 Green Tea

The combination of caffeine and antioxidants in green tea may lead to small to moderate reductions in body fat and waist size. However, you need to consume quite a bit of it so get creative and cook with green tea by brewing it and using it to cook rice (it’s particularly good with jasmine rice), make stews, soups or stocks. You can also poach fruit green tea or use dried green tea leaves as part of a rub for meats, tofu or fish.

9 Barley

Barley is a cereal grain with a nutty taste and consistency that is a cross between pasta and rice. In a double-blinded trial (both the men and the researchers didn’t know which food they were getting), Japanese men were given rice or a mixture of rice with pearl barley. The group receiving the pearl barley and rice mixture lost a significant amount of visceral fat, the kind that covers your organs like a thick winter blanket and increases risk of heart disease, stroke and type-2 diabetes. Compared to the rice only group, the group who ate pearl barley decreased their waist size.

10 Blueberries

Blueberries are an excellent source of dietary fiber, which will not only help keep you full but also help keep your waistline in check. Plus they are a natural source of prebiotic fiber – the kind that the good bacteria in your gut munch on.

A flat belly is one of the most recognized signs of a fit body. Blast away abdominal fat with high-intensity cardio and build the underlying muscle by regularly switching up your training program. Also, incorporate a 30-minute abs classes to your routine. At least one study found you can spot reduce if you exercise the same muscle group for at least 30 minutes at a time. Keep in mind abs are made in the gym but revealed in the kitchen. Add the top 10 flat belly foods to your diet while cutting down on sugar alcohols (sorbitol, maltitol, and mannitol are the worst for causing gas and bloating), fizzy drinks and chewing gum (all of these can increase bloating at least temporarily) and you may fall in love with skinny jeans.

Focusing on Fewer Ingredients in Food is Pointless

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

Zoning in on the number of ingredients in packaged foods is one of the stupidest consumer driven trends to date. Fueled by the unsubstantiated fear of anything not immediately recognizable or easy to pronounce, companies are turning to “fewer ingredients” to make their food stand out on over-crowded store shelves. Short, recognizable ingredient lists are leading packaged food trends in 2016 yet the number of ingredients or your ability to pronounce an ingredient has absolutely nothing to do with the nutrition value of the food and therefore shouldn’t guide your buying decisions.

The # of Ingredients Has Nothing to do with Nutrition Value

Shorter ingredient lists do not mean a food or beverage is better for you. Companies that make chips, ice cream and other dessert items are among the fiercest competitors for simplifying ingredient lists. According to an article in the Huffington Post, Hershey Co. improved their classic chocolate syrup by cutting the list to 5 simple ingredients. The new version took food scientists a year and a half to make with recognizable ingredients. The challenge? Making a syrup that also tastes good. The new version with cane sugar and organic invert cane syrup instead of high fructose corn syrup will cost you 1 more gram of sugar than the original version. How does this make it nutritionally superior to the old version?

Here’s another example. Let’s say you are in the grocery store debating between protein choices for dinner. Do you pick up the omega-3 and protein-packed (23 grams for 190 calories) salmon or beef franks (15 grams protein for 190 calories and 3x the saturated fat). I hope you choose the salmon if you are choosing based on nutrition value.

Simple Ingredients

I found many similar examples in the grocery store including potato chips with just a few ingredients compared to whole grain, higher fiber crackers with three times the ingredients and Häagen-Dazs ice cream with five ingredients, 250 calories and almost 5 grams of sugar per ½ cup compared to Giant brand ice cream with more than twice the number of ingredients, 160 calories and less than 3 grams of sugar per ½ cup. If you are choosing your dessert not based on taste but instead based on the nutritionally superior option (because that’s why people are focusing on the total number of ingredients right?), you’ll pick up the Giant brand with more ingredients.

Just Because You Don’t Recognize it and Can’t Pronounce it Doesn’t Mean it is Bad

Head over to Cooking Light or any other well-recognized cooking magazine and I’m willing to bet you’ll find ingredients that you don’t recognize and can’t pronounce. I live in the world of food, nutrition and supplements and restaurant menus often stump me while the sheer number of unfamiliar spices in Penzeys Spices satisfies my creative desire for something new and unique. Just because an ingredient is unfamiliar to you does not automatically make it bad. After all you’re probably not a food scientist entrenched in the world of food development and food safety.

Some misunderstood ingredients are emulsifiers – they help ingredients stay together in a mixture vs. separating (for example, salad dressings often contain emulsifiers including lecithin), others add nutrition value, help products retain their color, prolong shelf life or keep the product safe. Pyridoxine hydrochloride sounds scary right? It’s a vitamin B6. Cyanocobalamin? That’s vitamin B12. Beta-glucan? Oat and barley beta-glucan are soluble fibers sometimes added to food to increase the fiber content. They also help you feel more full (satiated) and are fantastic for your immune system. Lupin kernel fiber – lupin is a legume. In other words, it’s good for you. All substances allowed in food in the U.S. are GRAS – Generally Recognized as Safe by the Food and Drug Administration.

Even though manufacturers are scurrying to chop down their ingredient lists to meet this silly consumer demand, focusing on the number of ingredients in a food isn’t worth your time or attention span. If you don’t order food in a restaurant based on the number of ingredients used in the recipe why would you choose foods in the grocery store based on the total number of ingredients? In addition, don’t be scared of any ingredient with a sprinkling of scientific reasoning behind its use.

 

 

 

 

 

 

 

3 Major Myths About Organic & Conventional Food

Tweet about this on TwitterPin on PinterestShare on LinkedInShare on Google+Share on FacebookBuffer this pageDigg thisEmail this to someoneFlattr the authorShare on StumbleUponShare on Reddit

organic blueberries, raspberries and blackberries

 

There is very little that distinguishes organic food from conventional food. In an attempt to follow the pervasive “good food vs. bad food” storyline, many people have grossly exaggerated the differences between organic and conventional foods leaving readers with few facts grounded in scientific evidence. Don’t let the top three misperceptions about organic and conventional food influence your food choices.

This post covers:

  • Pesticide residues on food and human safety
  • Organic foods, conventional foods and the environment
  • Nutrition differences between organic and conventional foods

This post does not cover worker safety or in-depth environmental issues.

#1 Myth: Organic Foods are Grown Without Pesticides

Both organic and conventional crops are sprayed with pesticides, compounds that control a variety of pests (1, 2). In fact there is a long list of substances, including pesticides, allowed for use on organic farms. The differentiating factor between organic and conventional farming is the source of pesticides. Organic farmers primarily use naturally occurring pesticides in addition to a small number of man-made pesticides while conventional farmers primarily use man-made pesticides.

In some instances there is a man-made form of a compound identical to the one found in nature. For instance, methyl bromide, a fumigant gas used to kill fungi, nematodes and weeds, is found in nature and also made in a lab. Both conventional and organic farmers can use methyl bromide on strawberry plants. Bacillus thuringienis, the most commonly used organic pesticide, is both naturally occurring and man-made; incorporated into some genetically engineered foods. One is natural, one is man-made yet there is no detectable difference between the two (3).

#2 Myth: Organic Foods are Safer for Human Consumption and Better for the Environment

Compounds found in nature are not automatically safe and non-toxic, or safer than man-made compounds (4, 5). Both naturally occurring compounds and man-made chemicals are completely harmless, extremely toxic at a certain dose, or fall somewhere in between these two extremes. You’ve probably heard the saying “the dose makes the poison.” Many compounds we consume every day, from vitamin A to water, can be lethal if consumed in extremely high doses. The same is true for pesticides. Dose and length of exposure determine toxicity. Our government has several safeguards in place for the use of pesticides. First, the EPA evaluates all pesticides. Prior to use in the United States pesticides must be free from unreasonable risk to human health or the environment. Regardless of the type of pesticide used, whether organic or man-made, the Environmental Protection Agency limits the amount of pesticide residues allowed in food and water. The USDA Pesticide Data Program routinely monitors pesticide residues in foods and has found pesticide residues, whether organic or conventional, “pose no safety concern” (8, 9).

Organic pesticides are also not necessarily better for the environment, though they are considered safe in the amounts used (just like man-made pesticides). As an example, rotenone, a naturally occurring compound used in fisheries and can be fatal if inhaled (staff spraying this pesticide must be protected from risk of inhalation) and kills fish within an hour of spraying. Waters treated with rotenone are closed for public swimming for several months after treatment allowing dead fish time to decompose. When used according to instructions, rotenone poses “no overall risk to human health” or the environment (6). In addition, a study in soybeans found organic pesticides did not control aphids (plant lice) as effectively as man-made pesticides and they were more detrimental to the environment (partly due to the amount that needed to be used) (7).

There are environmental effects, both good and bad, from conventional and organic farming. Organic farming has advanced nonchemical methods of pest control and in some instances improved soil quality while decreasing soil erosion. However, organic farming also produces a lower yield, which means more environmental resources are used to produce the same total amount of food.

Can’t we farm without any pesticides?

Sure. Some conventional and organic farms do not use pesticides. A conventional farm may choose not to get organic certification, even if they don’t use any pesticides, because of the cost of certification. Keep in mind pesticides help get rid of pests and, can therefore help make food safer by the decreasing the likelihood of pathogens such as E. coli through use of anti-microbial compounds (10, 11).

What about the “Dirty Dozen”, Should I Steer Clear of the Foods that have the Most Pesticide Residues?

Some groups rank foods based on total pesticide residues – foods that are the “most contaminated.” Though some foods may have more pesticide residues on them than others, a study from the University of California Davis found all 12 commodities identified in the Dirty Dozen contained pesticide residues well below the established safe level (called the chronic reference doses or RfDs for short). In fact, only one pesticide residue, found on bell peppers, exceeded 1% of the RfD, coming in at 2%. So the largest total “dose” of a pesticide residue found was still 50 times lower than the established safe dose. Three quarters of the pesticides detected were at levels 1,000 times below the RfD. Therefore, the 12 foods listed on the Dirty Dozen “most contaminated” foods pose “negligible risks” for consumers. Choosing organic over conventional to avoid the fruits and vegetables on the Dirty Dozen will not completely negate your exposure to pesticides (because some organic produce has pesticide residues as well) or lower your risk from exposure to pesticides because your risk is negligible to begin with (12). Given the low amount of pesticide residues found on conventional and organic produce, there’s little appreciable difference in total pesticide exposure, whether you eat conventional or organic.

Though some studies, as well as pesticide monitoring programs have found conventional produce contains significantly more total pesticide residues then organic produce, significantly more than a miniscule amount is still a miniscule amount. Here’s an analogy: if I give you one penny and give your friend 2 pennies, your friend has 100% more money than you do – that’s a statistically significant difference. However, the financial impact of two pennies vs. one penny is meaningless.

If you want to add up your total exposure, check out the Alliance for Food and Farming developed a pesticide calculator and research behind the calculator:

http://safefruitsandveggies.com/pesticide-calculator

#3 Myth: Organic Food is More Nutritious

Several studies have examined nutrient differences between organic and conventionally produced foods. Most of this research shows no appreciable difference in vitamin or mineral content or health effects. What about plant compounds including antioxidants? In some cases organic farming may improve antioxidant content while in others man-made pesticides actually increase concentrations of certain beneficial plant-based compounds (13, 14).

In a world where we have many food choices and an overabundance of incorrect nutrition information, it’s easy to grasp onto a concept that isn’t evidence-based. Don’t get caught up in the hype and instead look for the scientific details. When it comes to organic and conventional foods, you’re not stuck choosing sides but instead can enjoy both – there is no appreciable difference in pesticide residues or nutrition content between the two.
