Energy and Aging On the practical side, for your anti-aging success today, the main unifying theme of this issue is the body's energy systems. The body's storage and utilization of energy and ultimate failure in this regard has major repercussions in the aging process. Issues re lated to body energy usage are at the very heart of the aging process. Understanding your body's energy mechanisms will help serve as a guide to light the way in your life extension quest. Here is the short simple version of energy metabolism.
Glycolysis provides energy to body cells through the oxidation of glucose supplied from the blood.
The blood glucose comes either directly from carbohydrates intake or from glycogen stored in the liver and muscles. Glycolysis is regulated by the hormones insulin and glucagon. Lipolysis metabolism provides energy through the release and use of triglyceride fatty acids. This mostly happens during exercise, but depending on your metabolism and supplements, can also happen while at rest. It has been said that the only way to lose weight is to make calorie output greater than calorie input.
