Capsaicinoids from chili peppers boost metabolic rate

At rest, the body burns about 60 percent of total calories per day. Doctors thought if they could increase the resting metabolic rate, participants would lose more weight.

In this study, 40 men and women took a placebo or 2 mg of capsaicinoids per day while doctors remotely measured energy expenditure and heart rate at rest through a tracking device at one, two, and three hours.

After five months, while the placebo group had not changed, those taking capsaicin had an increased metabolic rate equal to burning an extra 116 calories per day, and losing one pound of fat over 30 days. There were no differences in heart rate in either group.
