Nature's Science Intermittent Fasting Fat Burner has isolated the fat-burning component in green tea that speeds up your metabolism. It is called fasting green and it has been shown in a published study to help overweight people lose up to 30 lbs.! In a study, participants who consumed a key ingredient in the intermittent fasting fat burner formula twice daily lost an average of 30.5 pounds of weight vs. participants who only dieted (10.1 lbs.) in just 13 weeks. Both groups consumed a reduced calorie diet of 1350 calories per day for women and 1850 calories per day for men. These statements have not been evaluated by the Food and Drug Administration.
