Dr Michael Mosley researches the effects of calories in our bodies and how it might affect our longevity. He learnt that with a planned diet of alternate fasting helps with keeping diseases at bay and we will all live longer and healthier too.
Intermittent fasting (IF) is a pattern of eating that alternates between periods of fasting (usually meaning consumption of water only) and non-fasting.
There is evidence suggesting that intermittent fasting may have beneficial effects on the health and longevity of animals—includinghumans—that are similar to the effects of caloric restriction (CR). There is currently no consensus as to the degree to which this is simply due to fasting or an (often) concomitant overall decrease in calories, but recent studies have shown support of the former Alternate-day calorie restriction may prolong lifespan. (IF and CR are forms of Dietary Restriction (DR), which is sometimes referred to as Dietary Energy Restriction (DER).)
Scientific study of intermittent fasting in rats (and anecdotally in humans) was carried out at least as early as 1943.
A specific form of IF is alternate day fasting (ADF), also referred to as every other day fasting (EOD), or every other day feeding (EODF), a 48-hour routine typically composed of a 24-hour fast followed by a 24-hour non-fasting period.
