Start at a low dose: Fat burners are designed specifically to give you the proper doses of various ingredients to support fat loss. But that doesn't mean that the more of the ingredients you take, the more results you'll see. Supplement manufacturers state the serving guidelines and directions so you can have a way of measuring what dose works best for you.
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 big part of weight loss is simply being aware of the decisions you’re making. For example, when out at happy hour with friends, you may lose track of how much you're eating or drinking. But if you take a split second to step back and become aware of that fact, you’re able to course correct. “The awareness and then planning for what else I can be doing, that might give me the same benefit of eating comfort foods,” says Gagliardi.
Surprised? Although olive oil contains fat, it actually contains a type of healthy fat that has been found to decrease levels of fat-storing inflammation. According to a review published in the International Journal of Molecular Sciences, a polyphenol only found in unrefined extra virgin olive oil—oleocanthal—reduces inflammation in a similar way that ibuprofen does: it prevents the production of two pro-inflammatory enzymes, COX-1 and COX-2.
A true gem when it comes to fat burning. Taking Green tea is a safe, natural way to boost your metabolism. In it you’ll find antioxidants also known as Catechins, these activate the fat burning hormone norepiphrine and help your body achieve greater weight loss through the process of ‘Thermogenesis’. This wonder leaf will help to reduce your appetite. It’s also a nice ingredient for women as it can help your body work against the fat storing hormone Erastidiol.
Berries are packed with polyphenol antioxidants that will help burn fat—and prevent it from forming—as well as boost your workout benefits by improving blood flow to your muscles. According to a Texas Woman's University study, mice that ate three daily servings of berries had 73 percent fewer fat cells. Pop some of the blue guys into your next smoothie and boost the fat-burning potential: blueberries are a potent source of resveratrol, an antioxidant which an International Journal of Obesity study showed could convert excess harmful white fat in mice into calorie-burning beige fat, which correlated with a 40 percent decreased risk for obesity. And when it comes to the sugar content in fruit, berries rank favorably on the list but are still a powerful way to curb cravings for sweets.

Chromium might help increase lean muscle mass, promote fat loss and reduces food intake. Research findings suggest that chromium usually has “minimal effect on body weight and body fat,” but the good news is that it also doesn’t seem to pose risks. There have been very little safety concerns reported at low to moderate intakes (25–45 micrograms a day for adults), although at higher doses headaches, watery stools or constipation are possible.

Ansari says alcohol can prevent weight loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly," she says.
To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.

One 2009 report published in the Journal of Nutritional Biochemistry found that CLA has positive effects on energy metabolism, adipogenesis, inflammation, lipid metabolism and apoptosis. (6) A 2007 study published in the British Journal of Nutrition similarly found that supplementation of a CLA mixture in overweight and obese people (three to four grams a day for 24 weeks) decreased body fat mass and increased lean body mass. (7) And regarding CLA’s safety, there seems to be very little risk for adverse effects on overall blood lipids, inflammation levels and insulin response in healthy, overweight or obese adults.
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.
