The science behind aging

This is a known fact by now that our body loses its lean muscles, sound sleep, growth and repair and so on and so forth. But why does body lose so many things with age. The reason is that as we age, the cell receptors lose sensitivity to the action of HGH, insulin, IGF-1, peptin, thyroid, and many other (perhaps all) peptide hormones.
There is a rise in the insulin level and this leads to a decrease in HGH secretion because insulin is known to have a negative impact on HGH. Tissue responsiveness to insulin and peptide hormones decreases progressively throughout life, beginning at age 17
With this loss of tissue sensitivity to insulin, glucose (carbohydrate) tolerance decreases predictably with age and secretion of insulin by pancreatic beta cells increases to compensate. Blood levels of insulin thus increase with age and the end stage of this process is type II, adult-onset, and non-insulin-dependent diabetes. If the pancreas finally becomes totally exhausted by excess production of insulin, insulin by injection may become necessary late in the disease. Gradual insulin resistance with increased production and elevated blood insulin levels occurs in most adults as they age, and increases as body fat increases. A diagnosis of diabetes occurs only at the end stage of this process, which exists for many years before blood sugar elevates.
The process can be delayed by aerobic exercise which acts to partially reverse and slow age-related loss of cell response to peptide hormones. Low glycemic index carbohydrates with fewer carbohydrates and simple sugars (requiring less insulin, as used in the Barry Sears’ “Zone” diet) can also improve tissue responsiveness to insulin. That also improves cellular responsiveness to HGH.
