He contends that the person on a complex CHO program responds well to insulin. The body better utilizes the CHO and glucose in the food. This stimulates a spurt of insulin Into the blood stream. The resulting overabundance of insulin sends the blood sugar down as rapidly as it ascended. No such abrupt response of insulin to glucose absorption occurs after eating a meal high in fiber, for there Is no rapid rise in blood sugar.
Fiber slows the digestive process so that absorption of glucose proceeds more slowly.
The rise is not as high and is more sustained. The Lexington diet, first introduced almost ten years ago, provides 65-70 grams, considerably more than the average. For insulin to be properly utilized, the docking sites must be filled with insulin. Obese individuals lack the acute sensitivity to insulin, because their Insulin receptors are fewer in number, hence fewer sites for insulin linkage. In addition to decreasing the rapid rise of blood sugar after a meal and increasing the number of insulin docking sites on white cells, a high fiber diet lowers blood fats, helping to carry cholesterol out of the body.
