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.
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.
Load up on low energy density foods, like vegetables, fruits and fat-free broths. A few minor tweaks can lower the energy density of your favorite meals, too. For example, substitute a half-cup of spaghetti and a half-cup of spiralized zucchini "zoodles" for a full cup of spaghetti. Or make a chicken, vegetable and brown rice soup instead of serving grilled chicken with brown rice and veggies; the broth is often very low or virtually free of calories, lowering the energy density of your meal, so you may fill up on fewer calories.
Don’t pass up on this cheap trick. “One of the most under-appreciated magic fat-burning elixirs is water,” says Ajia Cherry, ACE, CHC, CPT, personal trainer and Founder at Functional Innovative Training. “The more water you drink, the fuller you will feel, the easier it is to cut back on unnecessary calories. That’s an essential element of weight and fat loss,” she explains. Water is necessary to keep your metabolism functioning optimally. For even more of a kick, add a lemon to your glass. D-limonene, an antioxidant in lemon peel, has been shown to have a therapeutic effect on metabolic disorders in mice with high-fat-diet-induced obesity.
Sunny side up, scrambled, hard-boiled, or fried—it doesn’t matter. A pan, spatula, and carton of eggs are all you need to fry some serious flab. Eggs are one of the best sources of choline, a major fat-burning nutrient that helps turn off the genes responsible for belly-fat storage. Bonus: eggs are a great source of lean protein, which can set the fat-burning pace for your entire day when eaten for breakfast. In a study of 21 men published in the journal Nutrition Research, half were fed a breakfast of bagels while half ate eggs. The egg group were observed to have a lower response to ghrelin, were less hungry three hours later and consumed fewer calories for the next 24 hours!
