7 Medically Proven Weight Loss Supplements that Work

3. Caffeine

Enjoying a cup of coffee in the morning not only wakes you up, is also helps with weight loss. Studies have shown that caffeine acts as a metabolism booster and can increase fat burning by up to 29%. As a result of these studies, caffeine is often one of the main ingredients in weight loss supplements. However, the results are only short-term, because caffeine is addictive and the body can develop a tolerance towards it. This is why it is advised to take some caffeine-free days every couple of weeks. Another advantage of caffeine is that there’s no need to buy a special supplement or pill; you can instead stick to good coffee, green tea, or dark chocolate, which also contain antioxidants.
