Background: In order to study and assess the efficacy of green bean coffee extract as a weight loss supplement, human clinical trials were conducted through randomised, double-blind, placebo-controlled, linear dosed crossover studies in the year 2011, in Trinity College, Bangalore, India.
Methodology: Given the potential side effects and rising costs of prescription weight loss medications, an increasing number of obese and overweight adults are looking towards nutraceuticals to assist them with weight loss. One such all natural, promising nutraceutical that was regarded by weight loss experts as a high influencer of glucose and fat metabolism was green bean coffee extracts.
Given the high concentrations of chlorogenic acid naturally occurring in green bean coffee extracts, a crossover study conducted over 22 weeks took place in order to examine the efficiency and safety of the green bean coffee extract in cutting down fact and reducing weight and body marks in 15 overweight individuals.
Participants received a high dosage supplement of green bean coffee extracts of over 1000 mg, a low dosage of 600 mg or placebos in separate intervals over a six-week treatment period, followed by a two-week washout stage to cut down any consequence of earlier experiment. Between the two groups of participants, the treatments were neutralized. Basic measurements such as percent body fat, heart rate, blood pressure, and body weight and body mass index were measured.
Results: The results revealed that there was substantial reduction of body weight, percent body fat, body mass index, in addition to a tiny decrease in heart rate among participants who consumed the highest concentration of green bean coffee extracts. It was further seen that six participants out of the total number of 16 participants under the green bean coffee extract group, the body mass index moved from pre-obesity to a normal weight range.
Conclusions: In conclusion, research scientists revealed that green bean coffee extracts should be considered as an effective nutraceutical in assisting with weight loss among adults who were on the border of obesity and could be looked at as an inexpensive supplement in preventing obesity among overweight individuals.
Additional research: The analysis of the trial study reveals that participants who received the green bean coffee extract experienced fat loss of over five pounds in body weight, as compared with those individuals who were under the placebo group. Since the major study conducted in 2011, a number of additional studies have been conducted across the world with similar success stories with green bean coffee extracts as a weight loss supplement.
A similar study conducted in Korea revealed that a substantial reduction in body weight and body fat percentage was seen among 25 overweight women, after eight weeks of green bean coffee extract usage as compared with participants under a placebo group.
