Some people believe that adding these additional fats can help to break a fast and stimulate weight loss. However, there is no scientific evidence to support this claim.

Bulletproof coffee is a type of coffee that is claimed to have a range of health benefits. These benefits include weight loss, increased energy levels, and improved mental clarity.
