Perhaps the oldest anti-aging technique on record is eating less. Wise men have known this for centuries. The thing that has changed is that now modern science has tested this approach, measured its effect and even found out how it works.
When you eat less, you get a number of benefits:

• Body temperature drops
• Blood pressure lowers
• Cholesterol levels drop
• Cells divide at a slower rate
• The rate of glycation drops
• Free radical activity drops
• Inflammation lessens

Essentially what is happening is a form of hibernation. You are “living less,” thus adding years to your lifespan. The less food you eat, the less your metabolic system has to work.
