umerous preliminary clinical studies continue to show promise of the remarkable weight loss, and other health benefits provided by the active KGM (Konjac glucomannan) compound found in both Tetrazene products. The below clinical abstract summaries of KGM studies, serve to detail the protocols and results of these key studies for your reference and review.

  • Patients report less hunger and greater satiety with glucomannan.
    A study done in Italy utilizing glucomannan in conjunction with a reduced calorie program demonstrated better results than diet alone including less hunger and greater satiety than those given a placebo. Improvements in body weight, blood glucose levels, and total serum cholesterol were also noted.

  • Glucomannan reduces insulin surge after meals.
    When administrated with meals, by blending into fluid or mixed with food, glucomannan can slow carbohydrate absorption and inhibit insulin response after meals by up to 50%. Clinical evidence also suggests that glucomannan promotes satiety and weight loss while improving LDL cholesterol and constipation with few side effects, if any at all.

  • KGM causes 5.5 pounds of weight loss in 2 months without dieting vs. a weight gain of 1.5 pounds in those given a placebo.
    Two groups of obese participants were asked to consume their regular diet. In addition, the control group was also given 1 gram of KGM, one hour prior to each meal with 8 ounces of water, while the other group received a placebo. At the end of the study, the control group lost an average of 5.5 pounds, while the placebo group gained 1.5 pounds. Just as impressive, the total and LDL cholesterol levels were reduced in the KGM group. There were no adverse effects experienced in either group.

  • KGM provides 10.4 pounds of weight loss in just one month.
    When KGM was added to a normal-caloric diet, it caused as much weight loss in one month as those subjects consuming a very low-calorie diet. According to the study, obese participants either consumed 2,000 calories a day and 1 gram of KGM prior to breakfast and lunch, or consumed 1,200 calories a day and given no KGM for the duration of a month. Those participants receiving KGM lost an average of 10.4 pounds, compared to 10.7 pounds in the extreme low-calorie group.

  • KGM causes 8 times more weight loss than a placebo -- without dieting -- and 13 times more weight loss with dieting, over the course of one month.
    Hypertensive subjects were divided into three groups consisting of those who were given 3 grams (1 gram 3 times daily) of KGM, the second group also received KGM in addition to a low calorie diet (varying between 1,000 and 1,800 calories a day) , while the third group received just a placebo. The KGM-only group lost 3.1 pounds, the KGM and low-calorie group lost 5.3 pounds, and the placebo group lost 0.4 pounds. Ten of the 31 participants (32%) reported a definite satiating effect. Also, five of the subjects previously suffering from constipation reported KGM was helpful. The authors of the study concluded "a dietary supplement, such as KGM, is therefore useful as a natural obstacle to nutrient intake in maintaining energy balance and in the management of the overweight."

  • KGM has pronounced ability to reduce appetite, and is well tolerated over the long term for obesity.
    This study examined the results of giving 4 grams of KGM (1.33 grams prior to each meal, 3 times daily) to severly obese subjects over a three-month period, in addition to a prescribed diet. The authors of the study concluded that, "KGM had a marked ability to satiate patients" allowing "greater adherence to the diet", and produced significant loss of fat mass, while improving lipid levels. Additionally KGM is well-tolerated over the long term.

  • Cholesterol reduced by 11 percent, fasting blood sugar by 29 percent using KGM.
    Over the course of 3 months, type II diabetic patients were given KGM. Measurements of total cholesterol and fasting blood sugar were recorded at the start and end of the study. Total cholesterol was reduced by 11%, and fasting blood sugar levels decreased by 29%.

  • Blood glucose levels and other associated risk factors improved with KGM supplementation in Type 2 diabetics.
    Eleven Type 2 diabetic subjects, who were also hyperlipidemic and hypertensive, were given KGM fiber-enriched (konjac mannan = glucomannan) biscuits containing 0.7g/100kcal KGM in addition to traditional treatment of a low-fat diet and medications. KGM significantly reduced serum fructosamine, the ratio of total to HDL cholesterol, and systolic blood pressure levels. The authors concluded that KJM fiber added to conventional therapy, may improve glycemic control, blood lipid profiles, and systolic blood pressure in high-risk Type 2 diabetic individuals, thus further improving the effectiveness of conventional treatment protocols versus a placebo.
