Now that you're familiar with everything we covered in Can Active Phase Calorie Restriction Increase Life Span? it's time to explore the science behind it...

According to Dr. Takahashi, previous research done in the 1930s had shown that cutting calorie intake by 30% could extend life span in addition to health span -- the amount of time before age-associated diseases such as heart disease, cancer, or diabetes develop. This has been shown in research in many different species. Recent research indicates that bouts of fasting and limiting calorie intake to active hours also improves health. 

As mice are nocturnal and the majority of calorie-restriction studies have been done on mice during the daytime schedule, the UTSW group used automatic feeders to mimic normal sleep-wake cycles.

The life span and health of the six groups of mice were followed for four years to evaluate the impact of calorie restriction, fasting, and meal timing.
