No. Nope. Definitely not. Sorry. Even the ingredients above that have been shown to elicit a calorie-burn eliminate, like, 70 calories at most. That’s one Oreo. This isn’t to say you can’t ever ease up on your diet, or cheat, or increase your food intake when you’re in a strength-gaining phase — but you can (and should) do these things whether you’re taking a fat burner or not. Taking a fat burner is no excuse to eat or train differently.
