The research behind a low calorie, high phytonutrient diet extending lifespan in mammals is quite extensive.
There have been variations on this theme of lowering the calories we take in. These can vary from full-blow calorie restriction to alternate day calorie restriction. There is the Bahadori leanness program that uses “mini-fasts” to reach and maintain optimal body composition.
Then there is research on the “longevity genes” (the SRT family of genes) and research on resveratrol for anti-aging. They all point to the same conclusions:
Too many calories kill us.
The human body is very well designed for starvation and adapting to low caloric intake. There are NO mechanisms in place to cope with the diseases associated with poor lifestyles. Sounds strange, huh?
How can diabetes and Alzheimer’s be “genetic” when our bodies have no mechanism in place to deal with the disease state? It’s the same with high blood pressure. How can high blood pressure be “genetic” when there is no mechanism in our body to control high blood pressure? We have a mechanism to raise blood pressure (aldosterone secretion from the adrenals), but not the reverse.
This particular review looks into the research that supports the idea of cutting back on calories (while maintaining quality) as a way of combating chronic disease.
