Soluble dietary fibers are great for weight loss, but if you are seeking a fiber that does more than just help you shed pounds, Glucomannan might be the right one for you. This powerhouse fiber not only helps you feel fuller and lose weight but also comes with added benefits such as better cholesterol and blood sugar control.
What is Glucomannan?
It is a dietary fiber derived from the root of the elephant yam or konjac plant native to Asia. Glucomannan has been part of traditional Chinese medicine used in the treatment of various conditions, including intestinal disorders, tumor prevention, and soothing burns. It is also used as a cough remedy, and for treating asthma, hernias, breast pain, and various blood and skin disorders.
Weight Loss benefits:
The soluble dietary fiber in Glucomannan absorbs water in the stomach, which expands and creates a sense of fullness, making you feel satisfied with less food. This natural fiber can also contribute to reduced calorie intake by reducing your appetite, making it easier to stick to a lower-calorie diet. Glucomannan also promotes good bacteria in the intestine which can in turn help with weight loss.
A study conducted in 2005 that examined the benefits of fiber supplements added to a fixed-calorie diet of 176 overweight participants found that Glucomannan could induce an average body loss of 0.8 kg per week.
A 2020 meta-analysis of 134 studies and six clinical trials revealed that glucomannan supplements could aid in weight loss for overweight and obese adults, leading researchers to recommend it as a practical strategy for reducing body weight in this population. The researchers noted that the supplement helped to prolong gastric emptying, improve satiety, and ultimately contribute to weight loss.
Cholesterol Control:
Glucomannan’s cholesterol-lowering power lies in its ability to reduce cholesterol absorption in the gut. A study that investigated the serum cholesterol concentrations in 63 healthy participants revealed that even without any change in diet and lifestyle, glucomannan intake reduced total cholesterol by 10%, low-density-lipoprotein cholesterol by 7.2%, triglycerides by 23%, and systolic blood pressure by 2.5%.
Blood Sugar Control:
Studies indicate that glucomannan is a powerful nutritional tool for managing type II diabetes. A recent study that analyzed six clinical trials found that glucomannan significantly reduced total cholesterol, LDL cholesterol, fasting blood glucose, and post-meal blood sugar levels in diabetes patients. Additionally, it reduced fasting insulin and serum fructosamine, both crucial indicators of blood sugar control.
Constipation: As a dietary fiber, glucomannan helps soften stool and is often used as a supplement to improve bowel movements. The findings of a 2018 study that investigated the use of glucomannan in constipation during pregnancy showed that the supplement helped to increase the frequency of bowel movements and stool consistency.
How to use Glucomannan?
Glucomannan is considered generally safe for both children and adults. Although there is no official guideline, the typical dosage ranges from 3 to 4 grams taken orally each day for up to 3 months for adults. In children, the dosage can range between 2 to 5 grams taken daily, with a maximum duration of use extending up to 4 months. To avoid drug interaction and the risk of reduced absorption glucomannan supplements need to be taken 1 hour before or 4 hours after other medications.
What are the side effects?
Taking glucomannan supplements without adequate water can be risky, as the fiber can expand and cause choking or blockages. Since this supplement has glucose lowering potential, the people with diabetic who are already on oral hypoglycemic agents, insulin, or other medications should take it with caution. It is also not recommended for people with esophageal and gastric obstruction.
