Knowing that dietary supplements — including weight loss pills, herbs, enzymes and teas — are not regulated by the Food and Drug Administration (FDA) in ways that other medications are, you may be wondering if they’re safe to consume. (2) Better yet, do weight loss pills or other fat-burning supplements even work, making them worth any potential risks involved? Studies have found that risks of fat-burning supplements can include nausea, headaches, anxiety, indigestion and trouble sleeping. Most adverse effects are caused by factors like interactions with medications, ingesting too much caffeine or consuming “filler” ingredients not even listed on the product’s label. While weight loss products may possibly give you a lift in energy and mood, they likely won’t be enough to sustain any real weight loss without other lifestyle changes.
According to the School of Sport and Exercise Sciences at University of Birmingham, “The term ‘fat burner’ is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.” (3)
You say tomato, I say 9-oxo-ODA. That's the name of a compound found in the brilliant red fruits that Japanese researchers recently discovered can effectively activate your DNA to burn more fat. Tomatoes are also brimming in beta-carotene and lycopene, two potent antioxidants that mop up harmful compounds that promote fat storage. One Journal of Nutrition study found people whose diets contained the most beta-carotene and lycopene had the smallest waists and the least belly fat. And at only 5 calories apiece, grab a few sun-dried tomatoes! Cooked tomatoes contain more bioavailable lycopene than raw tomatoes, according to Cornell University researchers.
Many teas have been shown to boost metabolism, block the creation of new fat cells, speed the release of fat from cells, and actually turn off fat genes due to their catechin levels, but green tea has a leg up on the competition. This magical elixir is particularly high in the antioxidant ECGC, the compound that burns fat and stops it from forming. Pair your tea with a workout for a fat-burning bonus. Exercisers who drank four to five cups of green tea daily and worked out for 25 minutes lost more belly fat than their non-tea-drinking counterparts, a study published in The Journal of Nutrition found.
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.

The most basic approach to weight loss is burning more calories than you consume. For instance, since 3,500 calories equals one pound of fat, a weight loss app—or even just a pen and paper—can help you decide how many calories you need to cut from your diet or burn at the gym in order to meet your goals. “If you were to burn 500 more calories per day seven days a week, that would lead to 3,500 calories in a week and one pound of weight loss,” says Gagliardi.


Caffeine: Studies show possible modest effects on body weight or decreased weight gain over time when consuming caffeine. Caffeine is usually OK in small to moderate amounts for most people but can also cause side effects like heart palpitations and restlessness. There’s no sound evidence that caffeine alone will help you lose weight, and the cons of taking too much caffeine definitely seem to outweigh the pros.
Spending more time in the kitchen can help you shed belly fat, as long as you’re cooking with the right foods, according to a 2017 study. After analyzing data from more than 11,000 men and women, U.K. 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.
