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.
DO IT: Assume a pushup position with your hands below your shoulders and your body forming a straight line from your head to your heels. This is the starting position. Lifting your right foot off of the floor, drive your right knee towards your chest. Tap the floor with your right foot and then return to the starting position. Alternate legs with each repetition.
This Asian veggie dish is made by fermenting a blend of cabbage, radishes, and scallions with a seasoned paste of red pepper, salted shrimp, or kelp (koji) powder. Fermented foods are great for healing your gut thanks to the high levels of probiotics, but the unique strains found in kimchi may also help you stay slim: Researchers at Kyung Hee University in Korea induced obesity in lab rats by feeding them a high-fat diet. The group that got a Lactobacillus brevis supplement— the culture strain found in kimchi—was able to suppress the diet-induced increase in weight gain by 28 percent! If kimchi isn't your thing, also consider adding one of these probiotic foods for a healthier gut to your diet.
In fact, researchers at Wake Forest Baptist Medical Center found that every 10-gram daily increase in soluble fiber was associated with a 3.7 percent decrease in dangerous visceral fat over five years. Those who were active got even leaner, shaving off twice that much fat in the same amount of time. To start ditching that extra belly fat today, add the best high-fiber foods to your menu!
Yohimbine: This ingredient, made from the bark of the yohimbe tree, is a popular stimulant in fat burners. It has been shown in a well-known study to produce significantly better fat loss results than a placebo among well-trained soccer players.[5] However, more research is definitely needed, and yohimbine isn't for everyone! If you're prone to anxiety or are very sensitive to stimulants, proceed with caution when it comes to yohimbine. Some people find it makes them very jittery or anxious.

If you've got weight to lose and you want it gone fast, try swapping out your usual proteins in favor of fish. Not only is fish lower in calories than an equivalent amount of beef or chicken, a study published in Obesity reveals study subjects who added omega-3 fatty acids, like those found in fish, to their diets shed more weight and had an easier time keeping it off than those who skipped them.
