Glucomannan

Glucomannan comes from the plant Amorphophallus konjac. It is chemically similar to guar gum. Acting like a soluble fiber by absorbing water in the intestines, it supposed to make you feel more full, which could help in sticking with a diet.

At doses of 3 to 4 grams, a few small studies have shown that this supplement helps produce a modest weight loss.

Some of glucomannan's side effects are: stomach pain, gas, diarrhea, nausea, and vomiting.

It is important you discuss any weight loss or exercise plan with your doctor. Only you and your physician can decide what is best for you. Some people have certain conditions that prevent them from doing all exercises, and goal body weights may be different for different people. You need to discuss all these things with your physician before starting any weight loss or exercise program.
