A fat burner is a dietary supplement that promises you’ll lose weight by boosting your metabolism so you’ll burn more fat. The diet industry is full of them – so there is no shortage of options available. That said, because they are dietary supplements, they are not Food and Drug Administration (FDA) approved. This means you need to pay close attention to the ingredients in the formula and the clinical evidence to support them. Not doing your research ahead of time could lead to bothersome side effects or potentially harmful drug interactions.

Scientifically Proven Fat Burners
You don’t want to waste time and money on a fat burner that doesn’t work. And most of the supplements on the market today claim they can give you results – without the science to prove it. Fortunately, there a few out there that do in fact work and have the research behind them to show it.
Green tea, particularly when combined with caffeine, can burn fat. It’s all thanks to the EGCG antioxidant found in green tea. And, while you make think drinking a cup of caffeinated green tea is enough – you’ll need a bit more oomph than the single cup provides. According to the International Journal of Obesity, “Catechins or an epigallocatechin gallate (EGCG)–caffeine mixture have a small positive effect on WL [weight-loss] and WM [weight maintenance].”
Cayenne pepper is more than just a quick and easy way to add some flavor and heat to your food. It seems that when you use enough of it, you’ll actually raise your body temperature, which leads to higher energy expenditure, and thus, fat loss. One study shows, “Consumption of capsaicinoids increases energy expenditure by approximately 50 kcal/day, and that this would produce clinically significant levels of weight-loss in one to two years.” Sure, this doesn’t seem like much, but when you combine it with other clinically proven ingredients in a single formula – it can pack a real punch.
A complete protein that provides all the amino acids your body must get from your diet, whey protein helps your body build and maintain metabolically active muscle. This helps you increase your calorie burn and keep it high as you lose weight – making it even easier to burn fat. Experts say you should aim for at least 15% of your daily caloric intake to come from protein every day.
