Guaraná for Weight Control
Why Use
Why Do Dieters Use It?*
Some dieters say that guaraná helps improve weight loss results.
What Do the Advocates Say?*
The herb guaraná contains caffeine and the closely related alkaloids theobromine and theophylline; these compounds may curb appetite and increase weight loss. Caffeine’s effects are well known and include central nervous system stimulation, increased metabolic rate, and a mild diuretic effect.1 In a double-blind trial, 200 mg per day of caffeine was, however, no more effective than a placebo in promoting weight loss.2 Because of concerns about potential adverse effects, many doctors do not advocate using caffeine or caffeine-like substances to reduce weight.
Dosage & Side Effects
How Much Is Usually Taken by Dieters?
Guaraná contains substances similar to caffeine that could be responsible for caffeine-like responses in the body, including central nervous system stimulation, increased metabolic rate, and a mild diuretic effect.3 There is no research demonstrating guaraná is effective for weight loss on its own.
