Why Excess Weight Kills

Of the many factors causing more than 40 percent of Americans to die of heart attacks and 35 percent to become diabetic, the strongest are eating too much and exercising too little.

Being Fat Makes You Even Fatter
Having diabetes is one of the strongest risk factors for heart attacks and premature death. Before insulin can do its job of driving sugar from the bloodstream into cells, it must first attach to special hooks on cells called insulin receptors. Only then can insulin drive sugar into cells. When fat and muscle cells fill with fat,
• these cells fail to respond adequately to insulin,
• blood sugar levels rise,
• insulin levels also rise,
• insulin converts sugar to fat,
• more fat deposits in fat and muscle cells, and
• you become even fatter.

How Being Fat Blocks Insulin Receptors
After sugar enters a cell, it can be 1)Used for energy, 2)Stored as muscle sugar called glycogen, or 3) be converted to fat. Once a muscle cell fills with glycogen, no more sugar can be stored in that cell so what is not burned for energy is converted to fat. The cell then fills with fat,
• Fat Blocks insulin receptors,
• Sugar is prevented from entering cells,
• Blood sugar levels rise,
• Sugar sticks to the outside surface of cell membranes, where
• sugar is converted to sorbitol,
• which destroys the cell to cause
• Blindness, deafness, MI, stroke, kidney failure, and all the other side effects of diabetes.

How Exercising after Fasting Prevents Diabetes
More than 90 percent of diabetes is caused by fat blocking insulin receptors so a diabetic cannot respond adequately to insulin. Emptying muscle cells of their stored fat helps them to respond to insulin and clear sugar from their bloodstreams. One major key to preventing and treating diabetes is to empty cells of fat. Contracting muscles burn mostly fat and sugar for energy. Muscles have only a limited amount of sugar stored in them and a virtually unlimited supply of fat. If you can exercise long enough to reduce the stored sugar called glycogen, in muscle cells, your muscles will be forced to use their stored fat. Emptying muscle cells of fat helps them to respond better to insulin. Exercising after fasting empties cells of glycogen rather quickly. This forces muscle cells to burns fat. This empties fat from muscle cells to increases a cell's response to insulin, which lowers high blood sugar levels (Journal of Physiology, November 2010)

Exercising Muscles Do Not Need Insulin
Furthermore, contracting muscles can draw sugar from the bloodstream without requiring insulin. Resting muscles cannot do this. The maximum effect lasts during exercise and up to one hour afterwards and disappears completely at around 17 hours. That's why you have to exercise every day to have your muscles respond maximally to insulin. (Am J Clin Nutr 2008(July);88(1):51-57. J Appl Physiol 2005;99; 338-343 & 2005;8750-7587.
