Using Fiber to Aid Weight Loss
The new PGX™ high-viscosity fiber blend may provide better results than ordinary fibers used in previous studies. Clinical studies have repeatedly shown that after-meal blood sugar levels decrease as soluble fiber viscosity increases.34,56 This relationship has also been shown with improved weight control and diminished appetite.40-43 We are anxiously awaiting the results of the ongoing weight-loss study of PGX™.
In the meantime, however, the dramatic effects shown by the PGX™ fiber blend in reducing insulin, glucose, LDL, and total cholesterol make it a common-sense supplement to take before meals. Any reduction of calorie absorption should benefit overall health. Taking steps to reduce excess insulin secretion may help protect against a wide range of degenerative processes.
Fiber: Limits to Weight Loss
The problem is that age-associated weight gain is a multifactorial process that can be only partially addressed with existing approaches. The scientific protocol on obesity in Life Extension’s Disease Prevention and Treatment book describes why it is difficult for people to lose significant amounts of body fat. There is help on the way, but the total solution in a pill is not yet here.
In the meantime, Life Extension recommends that people seeking to lose weight consume the following supplements:
Consider asking your doctor to prescribe 500 mg two to three times daily of the insulin-normalizing drug metformin.58-67 Men (without prostate cancer) should restore testosterone to youthful levels to help reduce dangerous abdominal obesity.68-108 Thyroid hormone deficiencies should be corrected.109,110 Make some effort to reduce consumption of high-glycemic foods, and to exercise, if possible.111-114
In today’s gluttonous world, overproduction of insulin has become a major health problem. Even in people who eat a healthy diet, the aging process often causes insulin resistance that results in higher-than-desired insulin levels. An overwhelming number of scientific studies shows that hyperinsulinemia is an underlying culprit for many of today’s killer diseases and infirmities.
While pharmaceutical companies are investigating insulin-suppressing drugs, the good news is that fiber supplements have been shown to enhance blood sugar control, decrease after-meal insulin levels, and reduce the number of calories absorbed by the body.
The best fiber sources for reducing after-meal blood sugar-insulin levels, lowering cholesterol levels, and promoting weight loss are those that are rich in water-soluble fibers such as glucomannan, psyllium, guar gum, and pectin.
When taken with water before meals, these fiber sources bind to the water in the stomach and small intestine to form a gelatinous, viscous mass that not only slows down the absorption of glucose, but also induces a sense of satiety (fullness) and reduces the absorption of calories.
With the introduction of a new highly viscous fiber blend trademarked under the name PGX™, it may now be possible to achieve the multiple documented benefits of fiber by swallowing only a few capsules before each meal. The longevity potential associated with reducing after-meal glucose and insulin blood levels, lowering total cholesterol and LDL, and losing some weight is enormous.
