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.

Can You Lose Fat and Gain Muscle at the Same Time?

Eat fewer calories than you burn each day and you’ll lose weight. There’s one major issue with this time-tested approach: you’ll probably strip away more than just body fat. Weight loss, especially fast weight loss, achieved after crash dieting or drastically slashing calorie intake, leads to a decrease in muscle mass and subsequent drop in metabolism. A slower metabolism means your body needs even fewer calories to maintain your new weight (weight loss alone = fewer calories needed to carry around a smaller body, add muscle loss and your calorie needs drop even more). In addition, with less muscle you won’t be able to push yourself as hard during workouts (and therefore burn as many calories). This can put you on the fast track to yo-yo dieting, weight loss and regain. There’s a much better approach and a recently published study highlights how you can lose body fat and gain muscle at the same time.

crash dieting leads to muscle loss

In this article I’ll cover:

  1. How dieting can slow your metabolism;
  2. The latest evidence on losing fat and building muscle at the same time;
  3. Why researchers didn’t use a low carbohydrate diet;
  4. How you can keep the weight off.

How Dieting Slows Your Metabolism

When you eat fewer calories than you need each day, your body is forced to pull from its backup supply, body fat and muscle, to maintain your energy (calorie) needs. Some people lose a substantial amount of muscle when dieting, 30% or more, of their initial muscle mass. In addition to a decrease in muscle mass and slower metabolism, lower calorie diets decrease the intracellular signaling necessary for the synthesis of new proteins in muscle. Plus, muscle tissue may be less sensitive to protein when you’re dieting. In other words, it’s really tough to build muscle when dieting to lose weight. Based on these physiological changes, there’s an age-old theory suggesting it’s impossible to gain muscle and lose fat at the same time. However, scientists from McMaster University in Canada found it is not only possible but also, doable even when losing a substantial amount of body fat in a relatively short period of time.

Building Muscle While Losing Body Fat

In the McMaster University study, young overweight recreationally active men (prior to the study they exercised 1-2 times per week) were placed on an intense four-week diet and exercise program. Their diet contained 40% fewer calories each day than needed for weight maintenance. All meals were prepared and provided to participants during the study. The men were randomly selected for one of two diet groups:

  Higher Protein Group

 

Lower Protein (Control Group)

 

Total daily calorie intake 15 calories per pound of lean body mass 15 calories per pound of lean body mass
Macronutrients 35% protein, 50% carbohydrate and 15% fat 15% protein, 50% carbohydrates, 35% fat
Total daily protein intake 1.09 grams of protein per lb. body weight (2.4 grams of protein per kg) 0.55 grams of protein per lb. bodyweight (1.2 grams of protein per kg) – 2x the RDA (0.8 g/kg) for protein

 

Per meal protein intake 0.22 grams of protein per lb. of body weight

 

0.10 grams of protein per lb. of body weight

 

Dairy shakes 3- 4 / day including one after exercise (depending on body weight; higher protein, lower carbohydrate shakes compared to the Lower Protein Group)

 

3- 4 / day including one after exercise (depending on body weight; lower protein, higher carbohydrate shakes compared to the Higher Protein Group)

 

Training Program
Supervised workouts consisted of full-body resistance circuit training twice per week and high intensity interval training six days per week. In addition to their structured exercise program, all participants were instructed to get at least 10,000 steps per day as monitored by a pedometer worn on their hip.

Resistance Training Circuit
2 times per week
3 sets of 10 reps at 80% 1 RM with the last set of each exercise to failure
No rest between sets
1-minute rest between each circuit

Sprint Interval Training
1 time per week
Four to eight 30-second bouts on a stationary bike (participants started with four sets and progressed to eight sets)
4 minutes rest between bouts

Modified High Intensity Interval Training
1 time per week
10 bouts of all-out sprint for one minute at 90% VO2max
1-minute rest intervals at 50% VO2max

Time Trial
1 time per week as fast as possible until approximately 250 calories were burned

Plyometric bodyweight circuit
30-second rest between exercises

Results
Both the lower protein and higher protein groups lost weight with no significant difference between groups. Men in the higher protein group gained 2.64 lbs. of muscle and lost 10.56 lbs. of body fat while men in the control group gained little muscle (0.22 lbs.) and lost 7.7 lbs. of fat. Both groups improved all but one measure of strength in addition to aerobic and anaerobic capacity. There were no differences between groups in strength, power, aerobic fitness or performance at the end of the study.

In this study, a higher protein, reduced calorie diet combined with a high intensity circuit-training program including interval training and sprints helped participants build muscle. In addition to their total protein intake, participants in the higher protein group also consumed more protein per meal (approximately 49 grams per meal) than those in the lower protein group (approximately 22 grams per meal).

Why Didn’t They Cut Carbohydrates?

Low carbohydrate diets are not only popular, but they may lead to greater weight loss (in overweight and obese individuals), initially, than higher carbohydrate, low fat diets (some of this is water weight). However, when giving up carbohydrates you also sacrifice something else, intense training. Carbohydrates are the primary source of fuel used during high-intensity exercise because your body can readily access and utilize them for energy. Fat is a slow source of energy and therefore, your body cannot access and use fat quickly enough to sustain high intensity training. In this study, both groups of participants consumed 50% of their calorie intake from carbohydrate. If the study authors cut carbohydrates, the participants wouldn’t make it through their high intensity training program that was specifically designed to take off fat and increase muscle mass.

Keeping the Weight Off

Consider a program like the one used in this study a short-term jumpstart. It isn’t sustainable over a long period of time. The transition to a longer-term approach after weight loss should include a gradual increase in calorie intake while maintaining a higher protein diet (at least 0.55 grams of protein per lb. of body weight to maintain muscle while considerably more, along the lines of 1.09 – 1.41 grams of protein per lb. of body weight may be necessary to continue building muscle during periods of reduced calorie intake). This gradual increase in calorie intake is important because substantial weight loss results in a slower metabolism even if you maintain or build muscle during your jumpstart weight loss program. It isn’t entirely clear why this happens and the drop is greater than scientists can predict based on a decrease in muscle mass. Even if you build some muscle, this won’t rev fire up your metabolism to make up for a drastic decrease in body weight.

One pound of muscle burns a measly 5.9 calories per day at rest while a pound of fat burns 2 calories per day at rest.

Greater weight lost while dieting means an even greater drop in metabolism – something dieters must account for so they can maintain their new weight.

In addition to slowly increasing calorie intake and consuming a higher protein diet, each meal should contain at least 25 – 30 grams of protein. We don’t know the exact amount of protein per meal needed to maximally stimulate muscle building.

Your exercise regimen should continue to include resistance training and you’d be wise to continually vary your training program. Be sure to move each day as well. Research shows many people naturally adjust to greater amounts of aerobic exercise by decreasing their activities of daily living. They exercise intensely at the gym and then sit the rest of the day. Circumvent this by using one of the many devices that counts steps each day. Also, consider doing more work around your house including cleaning, mowing your lawn, gardening, and washing your car. Get moving and stay moving all day long.

If you want to get rid of your love handles while building a six-pack at the same time, combine an effective resistance training and high intensity interval-training program with a reduced calorie, higher protein diet. Your diet and exercise program does not need to be as rigorous as the one in this study. Instead, you can adjust the McMaster University approach to fit your lifestyle, though your results may take more time. Once you reach your goal weight, slowly transition your training program and diet to an approach you can live with.
