To test the effects of a standardized green coffee extract on weight loss, 16 overweight people (average age 33 years) took a high dose (1,050 mg per day) of green coffee extract, a low dose (700 mg per day) of green coffee extract, and placebo, each separately for six weeks, with a two-week break between phases. The participants didn’t change their diets during the trial. Body weight, BMI (body mass index), and percent body fat were measured before, during, and after each period of the study.
Both dosages of green coffee extract led to significant reductions in percent body fat, body weight, and BMI. Percent body fat also decreased significantly with placebo, but body weight and BMI remained unchanged. While taking green coffee bean extract, the people lost an average of almost 18 pounds and 4.4% of their body fat. What’s more, 88% of the people maintained their weight loss four months later. No side effects related to the treatment were reported.
The study suggests that green coffee extract may be effective for helping to reduce weight and body fat in overweight individuals.
While the individuals in the study did not modify diet or engage in exercise we think that best results and long term health would require diet modifications and an exercise program.
