Green Coffee beans
There are a number of weight loss products out there. The claims range from genuine, verifiable claims to wild, unprovable claims that have never been substantiated. The products themselves range from being effective, to safe but not very effective, to actively harmful. The conscientious weight watcher, looking for a little natural help in shedding the pounds, will find that the information on each product is varied, but it is possible to come to a consensus before trying something out. The following presents the evidence for green coffee bean extracts.
Green coffee bean extract – what is it?
Green coffee beans are basically the same as the coffee beans we are familiar with, except that they are not yet dried and roasted – they are the raw seeds from the coffee plant. Coffee is known to contain caffeine, and caffeine has its own benefits – it keeps people active and away from depression. But raw coffee beans contain an extra chemical in addition to caffeine, and that chemical is chlorogenic acid. This is the secret chemical in coffee bean extracts that has weight loss effects. Unfortunately, roasting coffee beans reduces the amount of chlorogenic acid, so that’s why only the extract has enough of the acid to facilitate weight loss.
Green coffee bean weight loss effects
The research on chlorogenic acid includes a research published in January 2012 in the Diabetes, Metabolic Syndrome and Obesity journal. This study looked at the effect of weight loss in 16 adults. All of the adults were overweight (BMI>25). The overall weight loss they experienced was around 18 pounds.
Green coffee bean extract in the media
Green coffee bean extract has also featured in the media. Dr. Oz, as always quick to look for fat burning solutions, also did an experiment in which 100 women who were overweight (but did not have any other medical condition) were enlisted and their weights measured. Half of them were given the supplement and half were given a placebo, and they were told to measure their food intake for two weeks. At the end of the two weeks, the placebo group lost an average of one pound per person while the other group lost two pounds.
What to look for in green coffee bean extract
The active chemicals in green coffee bean extract are usually labelled in two ways. One is GCA which stands for green coffee antioxidants. The other way is Svetol. Both are basically the chlorogenic acid and other acids that are present in raw coffee beans and that may contribute to the weight loss effect.
Another thing to look for is the percentage of chlorogenic acid. Capsules with 45% or over 45% chlorogenic acid were the kind that was used for testing in Dr. Oz’s show. Capsules with a lower percentage or with no ingredients marked on the label should not be taken. It is up to the consumers to be very careful about these instructions because otherwise they may be duped by fraudulent companies. Always use trusted suppliers like Amazon.
Dosing and Precautions
The capsules come in various dosages, including 200mg, 400mg and 800 mg. However, the women in the TV experiment were given a dosage of 400 mg because this was thought to be effective. However, some studies show an effect even with 200mg. The capsules should be taken 3 times a day before meals. Children should avoid the extract, as should pregnant and lactating women.
Where to buy
The best place to buy your extract is, obviously, from a supplier you can trust. We recommend Amazon. They supply pills such as the ones here.
