Does drinking coffee help lose weight?
Caffeine is found in almost every commercial fat-burning supplement — and for good reason. It’s one of the few natural substances proven to aid fat burning.
Several studies show that caffeine can boost your metabolic rate by 3–11%.
Other studies indicate that caffeine can specifically increase fat burning by as much as 10% in obese individuals and 29% in lean people.
However, it’s possible that these effects diminish in long-term coffee drinkers.
