BCM CAM Study Study performed on overweight mice Methods
• Mice were fed a standard diet for 14 days Diet intake was not reduced
• Diet consisted of GCBE containing caffeine (10%), and chlorogenic acid (27%)
BCM CAM Study Results
• There was a significant weight loss of mice epididymal and perirenal fats
• No significance showing that caffeine relates to weight loss of body weight and visceral fat, however it does show significance in fat absorption rates
• Chlorogenic acid showed a weak correlation with body weight loss and visceral fat loss, but showed significance in suppressing hepatic TG levels
BCM CAM Study Conclusion
• GCBE shows a significant effect on weight loss in mice
• Caffeine suppresses fat absorption• Chlorogenic acid enhances fat metabolism
in the liver
