It is natural, as we get older, that our metabolism begins to slow; actually, it has a tendency to slow just a little each year unless you do something to prevent it. See, the more a person slow down the more your metabolism slows down. If you stay energetic - bodily active - your metabolism will too; which is in which the order rapamycin comes into play.
You can help the rate where your metabolic process processes energy by building muscle. Muscle burns fat -- a lot of body fat - even during resting periods like when you are asleep. One of the main reasons for this is that muscles need a lot of one's in order to maintain their "shape" as well as strength. (Keep in mind, metabolism creates energy output.) Therefore, the more muscle you have the faster your own metabolism will be and the more efficient your body is going to be at the anti-aging procedure.
Muscle is not something that you are either lucky to possess or not; you need to work at it. Even if you possess muscle inside your younger years, you will have to work to maintain it as you grow older. Just like your metabolism, muscle begins to devalue around the chronilogical age of 30 and slowly depreciates each year after that. Muscle mass depreciate can actually be pretty significant when you hit your 50s when it's depreciated at a 15% and increases to 30% after age 70. While you may not understand the risks included, yet, this is not a risk you want to capture.
Okay, therefore we know that a slow metabolism and losing muscle mass will happen as we grow older, yet we want to avoid it. If you maintain these two aspects of your body you will have provided your body its very own anti-aging agent. All of us already know the why; metabolic process burns calories which help to help keep the fat away; muscle needs these energy (also helping to keep the body fat off) but also provides a company look to your body that usually only comes with youth. The issue, now, is when do you attain this anti-aging broker?
