Glucomannan is a soluble fiber that is said to be able to absorb up to 200 times its weight in water. It is used as a fiber and weight loss supplement. Since it can absorb and grow quickly, it gives a person a feeling of satiety and fullness which can last for some time. This can help reduce appetite and decrease cravings as well. This substance is an extract that is gleaned from several different plants. The most common source of this product is an African plant called Konjac.
This dietary fiber supplement works in the digestive tract by slowing down digestion. Fiber such as this takes much longer for the body to digest. It also helps to decrease the amount of fats and carbohydrates that are actually absorbed in the digestive tract of the body. This also helps to aid digestion by promoting regular bowel movements which rid the body of toxins and wastes.
To test the efficacy of glucomannan, two clinical research studies were done using this product as a weight loss supplement. The first research study followed two groups of people who were extremely obese. Half of the group were given this supplement plus placed on a low calorie diet and followed for three months. The other half of the group did not receive glucomannan but followed the low calorie diet by itself. At the conclusion of the study, the results revealed that the group that was given glucomannan were able to lose much more weight than the group who was were placed on the diet alone. The glucomannan group also lost a more significant amount of body mass and body fat when compared to the other group.
The second study followed two groups of obese people. Half were given glucomannan and half were given a placebo. Both groups were given instructions to not to change their dietary habits. At the conclusion of the study, the glucomannan group lost more weight than the other group was able to. The glucomannan group lost on average 5.5 pounds and their serum cholesterol levels dropped 15-20 mg/dl.
There have also been other studies that allude to the fact that using this dietary supplement will lower the cholesterol levels in both adults and children. Researchers found that the fiber supplement did indeed lower cholesterol levels without affecting blood pressure readings. There was also evidence that glucomannan may well be able to help control blood glucose levels in people who have diabetes. Glucomannan has also been used to treat chronic constipation with excellent results.
Products and foods that are high in fiber have been shown to increase metabolic rates, burn more fats, increase lean muscle mass in the body, and give dieters the feeling of being full and satisfied for longer periods of time. This reduces appetite levels and cuts down on cravings in individuals as well. These are but a few of the reasons that they are considered excellent foods and supplements to use in conjunction with weight loss programs.
This type of herbal supplement can be safely added to a well rounded nutritious diet and exercise routine in order to achieve weight loss goals. A good diet includes lean proteins, fruits and vegetables, whole grains, and low fat dairy products. Particular attention should be paid to foods that are high in fiber and low in caloric value. These foods raise the metabolic rate and help to facilitate weight loss goals.
Other fats should be limited or avoided as should high carbohydrate or complex carbohydrate food products. These foods are responsible for people gaining weight and slows down the metabolism.
