Not sure about the weight loss end of the sales pitch however I can tell you this has a great detox or probiotic effect. I train 5 days a week and eat 90/10 clean. At times the amount of fiber in take in will cause issues with my ability to process and pass...anyhow this has helped with bloating and the above noted issue. It has a great light taste, not bitter, nor tasteless. I didn't add any sweetener and loved the taste on its own. Will buy again.
One reason excess visceral fat is so harmful could be its location near the portal vein, which carries blood from the intestinal area to the liver.

The Ovary belly comes with additional symptoms like thin hair, bloating, frequent acne outbreaks and headaches, heavy periods, facial hair and ovarian cysts.
