Intermittent Fasting Study Shows 12% Lifespan Increase in Male Mice, But Caloric Restriction May Be the Cause
By

Summary
This article examines a study on time-restricted eating (intermittent fasting) in male mice, which found that restricting food access to an 8-hour window increased median lifespan by 12%. However, the article notes this benefit may actually stem from voluntary caloric restriction induced by the feeding schedule rather than the timing itself. It contextualizes these findings within the broader debate about whether time-restricted eating provides benefits independent of calorie reduction, noting that human studies have shown mixed results.

· 4 pulledRestricting food access to an 8-hour window increased median lifespan in male mice by 12%.
However, that might be due to voluntary caloric restriction induced by the regimen.
Time-restricted eating (TRE), also known as intermittent fasting, has become a popular health practice due to a slew of animal studies showing its benefits for healthspan and lifespan.
Its record in humans, however, has been uneven.
