Green Coffee Extract Claims to Help People Lose a Pound Per Week: Dr. Oz

Green coffee diet is the latest diet craze to sweep Hollywood and Dr. Oz featured the green coffee bean on his popular show, leading many more women to become curious about its benefits.

According to Komo News, singer Katy Perry used Green coffee bean extract to get in shape for her Vogue cover. Perry hasn't specifically mentioned the holistic weight loss supplement to the press but she did say that she went on a "cleanse" before stepping in front of the camera for Vogue.

"I did a lot of my own prepping. I kind of went on a cleanse; I did a lot of stuff like vitamins and supplements. I didn't drink alcohol for three months. I was really in the zone, I just wanted to be glowing for that cover."

Green coffee extract hasn't been scientifically proven to make people lose weight, however Dr. Oz claims it does.

"The group that eats well with the green coffee bean extract lost an extra pound per week more... which doesn't sound like a lot, but again, you're not doing anything else." Dr. Oz also said that eating green bean coffee by itself won't help you lose weight. You also have to eat right and exercise.

Others also believe in the power and effectiveness of green coffee extract.

"Green Coffee Extract has been rated as the best green coffee supplement by users and independent review sites. It is a product from Evolution Slimming, a well established health supplement company that is known for its quality supplements and great customer support. A highly recommended product that is worthy of 5 stars on the rating scale" says a BestFatBurnersOnTheMarket.com spokesperson.
