A handful of almonds packs a serious fat-burning punch: One International Journal Of Obesity and Related Metabolic Disorders study of overweight adults found that eating about a quarter-cup of almonds for 6 months led to a 62 percent greater reduction in weight and BMI, thanks to a compound that limits the fat absorbed by the body. And eating just 1.5 ounces of almonds daily led to a reduction in belly and leg fat, a 2015 study published in the Journal of the American Heart Association showed. For added effect, eat almonds before working out: The amino acid L-arginine can help you burn more fat while building muscle.
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, a study published in Diabetes Care revealed 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.
Kickstart your morning—and your metabolism—with this warming spice. Cinnamon contains powerful antioxidants called polyphenols that are proven to alter body composition and improve insulin sensitivity (which means it keeps blood sugar stable, preventing hunger-inducing spikes and crashes). Japanese researchers found that mice who ate a daily helping of cinnamaldehyde (the ingredient that gives cinnamon its flavor) lost belly fat, while those who skipped the spice did not. Add it to your overnight oats or sprinkle some in your coffee to reap the benefits.
