There seems to be a link between abdominal obesity and depression. There have been reports showing that cortisol, a stress hormone, is related to both depression and abdominal obesity. Some researchers suspect that people who are depressed may have higher levels of abdominal obesity because of elevated cortisol. More studies are needed to determine the underlying causes for weight gain among those who reported being depressed.
Science backs these ideas up when it comes shedding belly fat: In one study published in The Journal of Nutrition, researchers had overweight men and women follow a high-protein diet (30 percent protein, 40 percent carbs, and 30 percent fat) or a high-carb diet (15 percent protein, 55 percent carbs, and 30 percent fat). After one year of weight loss and maintenance, they found that the high-protein group experienced a 21 percent greater weight loss and 27 percent greater body fat loss on average than the high-carb group.

Keep a food diary. Write down everything you eat and drink to keep track of how many calories you're taking in and figure out what bad habits you need to correct. You'll be much less likely to go overboard if you know you have to write it down. You can also use a food tracking app if you prefer, which may make the process a bit easier since most apps calculate the nutrition values for you.
In addition to helping maintain heart health and keep inflammation levels under control, monounsaturated fatty acids, or MUFAs, may stop belly fat before it starts. Research in the journal Diabetes Care found that people who got roughly 25 percent of their total daily calories from MUFAs gained no visceral fat over the course of the study, while those who ate less MUFAs and more carbs added fat to their midsections. My favorite MUFA-rich food is olive oil because you can use it in so many meals (check out the belly-blasting breakfast I recommend), but avocados and nuts are other excellent sources. Pine nuts are particularly great because they also contain high levels of polyunsaturated fatty acids. These acids increase levels of two hormones that signal your brain when you’re full. Try snacking on one ounce of pine nuts (about the amount you can fit in a shot glass) 20 minutes before mealtime to avoid overeating.
Most of the bacteria that dwell in your gut are pretty useful. They produce hormones, regulate your immune system, digest food, extract nutrients, control your mood, manage your appetite, and much more besides. That obese people tend to have higher numbers of Firmicutes bacteria is no coincidence – according to research published in the online journal Nature, these bacteria increase the number of calories your body absorbs from food.
3. Exercise Ball Crunch: This is one of the most effective ways to strengthen and flatten abs. Studies show this exercise is 40% more effective than regular ab crunches as it targets smaller muscles for flat toned abs including the oblique’s for a small waist and the outermost muscles that your typical ab crunch may miss. To begin, lie down on the ball positioning it under the lower back. Place arms behind your head. Tighten your abs as you lift your torso off the ball while keeping the ball stable. Lower back down and repeat 15 times with 1-3 sets.
Doing crunches until the cows come home? Stop it! When you're down to your final inches of belly fat, the dreaded crunch won't be the exercise that finally reveals your six-pack. "You can't spot reduce," Jill says. Instead, she suggests doing functional exercises that use the muscles in your core—abdominals, back, pelvic, obliques—as well as other body parts. "These exercises use more muscles, so there is a higher rate of calorie burn while you are doing them," she says. Planks are her favorite functional exercise—they activate not just your core muscles but also your arm, leg, and butt muscles.
You know you're supposed to eat more protein to lose weight, but you might not know exactly why. Well, it actually has to do with how your body handles insulin. "Your body starts to produce more insulin as you age, since your muscle and fat cells aren't responding to it properly," explains Louis Aronne, M.D., director of the obesity clinic at Cornell University.
