Coffee lovers know of no better beverage to start the day. Caffeine helps to increase metabolic rate and burn more calories. Study participants burned an extra 79–150 calories in 24 hours after consuming 100 mg of caffeine a day.
The caffeine in coffee has also been proven to help improve mood and mental function. Coffee is also rich in antioxidants, and a study has found coffee to be the number one source of antioxidants in the U.S. diet. The antioxidants in coffee have been associated with a lower risk of diseases such as diabetes and Alzheimer’s.
