Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, research from Reina Sofia University Hospital reveals that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
Spending more time in the kitchen can help you shed belly fat, as long as you’re cooking with the right foods, according to one 2017 study. After analyzing data from more than 11,000 men and women, UK researchers found that people who ate more than five homemade meals per week were 28 percent less likely to have a high body mass index, and 24 percent less likely to carry too much body fat than those whole only downed three meals at home.
One study from the University of Adelaide in Australia suggests you may lose more weight when you work out towards the end of your menstrual cycle, as opposed to right when a new one begins. That’s because the hormones estrogen and progesterone tell your body to use fat as an energy source. "Women burned about 30 percent more fat for the two weeks following ovulation to about two days before menstruation," study author Leanne Redman says.

A study in the April 1999 issue of the Journal of the American College of Nutrition proved the calorie-burning benefits of muscle. The study put two groups of obese individuals on a very low-calorie diet. One group did only aerobic exercises four times per week while the other group did only resistance exercises three times per week. After 12 weeks, the aerobics group lost more weight than the resistance group. However, in the aerobics group almost one third of the weight lost was muscle. The resistance group lost only fat.


An effective reward is something that is desirable, timely, and dependent on meeting your goal. The rewards you choose may be material (e.g., a movie or music CD, or a payment toward buying a more costly item) or an act of self-kindness (e.g., an afternoon off from work or just an hour of quiet time away from family). Frequent small rewards, earned for meeting smaller goals, are more effective than bigger rewards that require a long, difficult effort.
2. Beta-alanine: This one doesn’t directly burn fat, but it does help you work out harder and longer, which in turn lets you melt that extra layer. The non-essential amino acid converts to carnosine, which is one of the strongest buffers against your muscles getting fatigued. Because carnosine keeps your muscles from calling it quits, studies have found beta-alanine can help your performance during HIIT, increase strength, and even help you gain more muscle to then reap all those metabolism boosts.
While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to researchers at Yale, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
