Glucomannan for Weight Loss and Weight Control

One in three American adults over 20 is obese. It’s a pretty shocking statistic and it’s led millions of Americans in search of a weight loss magic pill, the latest diet fad or other more drastic measures like bariatric surgery.

Currently, the market is saturated with every kind of weight loss pill, potion and supplement that run the gamut from effective to quack remedy.

Glucomannan is one supplement that has piqued the interest of scientists and researchers. It has been the subject of multiple studies and has been shown to aid in weight loss and weight management.

What is Glucomannan?

Glucomannan is a natural soluble dietary fiber made from the Konjac root (also called Elephant Yam). Konjac grows in warm subtropical to tropical locations. After 3 years, the root is harvested, cleaned, peeled, sliced and dried. The dried root is ground into a powder and undergoes further processing to separate the dense glucomannan fiber. The pure Glucomannan powder is then added to dietary supplements, drinks, to foods as a thickener and used as the main ingredient in shirataki noodles. Glucomannan powder has no taste or smell.

Glucomannan is gluten-free with very few calories and zero carbohydrates. What makes it such a powerful weight loss and weight control tool is its ability to absorb water. In fact, it can absorb up to “200 times its weight in water”. Glucomannan expands in the stomach promoting a feeling of fullness or satiety. It also reportedly reduces the absorption of fats and carbohydrates.

A 1984 study of 20 obese patients to test purified glucomannan fiber showed a “significant mean weight loss of 5.5 pounds” after using glucomannan for eight weeks. It also reduced serum cholesterol and LDL cholesterol (low-density lipoprotein cholesterol).

Another study on 2008 showed that it had a positive and beneficial effect on total cholesterol, LDL cholesterol, triglycerides, body weight, and fasting blood glucose,

Another more recent study in 2015 of 83 overweight adults receiving 3 grams of glucomannan versus a placebo showed that “glucomannan supplementation reduced body weight, body fat, and circulating cholesterol levels without the concomitant loss of lean mass and bone density often associated with weight loss”.

Besides body weight and cholesterol, it was found to have beneficial effects on blood sugar. A 2000 study highlighted its positive effects on lipid profile and glycemic control which suggest possible use in the treatment of diabetic patients.

The largest study conducted on glucomannan so far was the 2005 study involving 176 patients. One group was supplied with glucomannan fiber supplements and one group on the placebo. Both groups were put on a 1200kcal diet. The result showed that the glucomannan and diet group showed more weight reduction than the placebo and diet group.

The takeaway from these studies suggest that while glucomannan helps in weight loss, it should be combined with exercise and calorie control.
