Cut Calories to Extend Life?

If you ever wanted to know the latest about increasing your lifespan by lowering your calories then this comprehensive AJCN review with 162 references was written just for you. Ever since the 1930s it has been known that calorie restriction slows down aging and extends median and maximal lifespan. However, this can?t be done without wisdom as human populations that consume low-calorie diets that are restricted in protein and micronutrients have:

  • Short stature
  • Late reproductive maturation
  • Suppressed ovarian function
  • Impaired breastfeeding
  • Impaired fertility
  • Impaired immune function

Fortunately, many of the above side effects can be avoided by using more nutrient-dense food sources. For those in a rush Living Fuel makes a lot of sense. Also, using lean grass-fed animals as a protein source is another way to maximize life expectancy and the ever important omega 6:3 ratio.

I suspect the majority of the benefits from calorie restriction are related to its influence on insulin. Part of this is due to insulin's known action on many other systems, all of which could potentially affect longevity. Insulin:

  • Alters the expression of numerous other hormones
  • Stimulates the sympathetic nervous system
  • Promotes vasoconstriction

Interestingly, it is thought that one might be able to use exercise to create a ?relative? calorie restriction as exercise produces many of the same benefits such as:

  • Improved insulin sensitivity
  • Decreased fat mass (FM)
  • Reduced cancers
