Can drinking coffee help burn fat?

Researchers involved in the study tested to see if the caffeine in coffee stimulates these brown fat cells in humans. So the team determined the brown fat reserves of each volunteer and how much heat they produce using thermal imaging. 

The results show that drinking a single, standard cup of coffee may stimulate brown fat, which would increase the body's metabolic rate-meaning that making these fat cells work hard with the help of coffee burns more calories.
