Green Coffee Seed (Bean) Extract successful for fat-weight loss
Doctors at the University of Scranton in Pennsylvania recruited 16 overweight people for their study. They were tested three times for a six-week period each time. Some were supplemented with green coffee seed extract 700mg each day and some received 1050mg while others received inactive placebo for six-weeks. They then stopped treatment for two weeks to wash out the effects of the supplements and were switched into their next group and this was repeated a third time so that each test subject took part in each of the three groups. No substantive change was made to their diet or level and type of physical activity. Their calories were monitored averaging about 2,400 calories per day – by no means a weight reduction plan; they were not placed on a weight loss diet. They burned on average 400 calories per day in physical activity.
Thirty-eight percent of the test subjects moved from a classification of overweight (pre-obesity) to the normal weight range. On average on the green coffee seed and only while on the green coffee seed people lost 17.69 pounds with most of the test subjects loosing more than 10 % of their body weight and 16% of their body fat. These results are with just a twelve-week total period of using green coffee seed. Some of the subjects lost less than 10 pounds but others lost over 25 pounds. The higher potency was slightly better for weight loss.
The green coffee seed supplied 46 % chlorogenic acid; a major coffee seed antioxidant. The researchers feel it was the chlorogenic acid that burnt the fat and this was based on additional human and animal studies. Once you roast the coffee seed to make coffee for brewing you loose the chlorogenic acid. The coffee seed used was of high quality and naturally contained the chlorogenic acid; synthetic chlorogenic acid was not used in the study. The study is published in the journal Diabetes, Metabolic Syndrome and Obesity.
