Yo-yo Dieting in Mice Shows Longevity Benefit in Controversial New Study
Dr David Allison, from the University of Alabama in Birmingham, USA, found that obese mice repeatedly placed on crash diets - presumably involving some degree of calorie restriction - lived longer than mice maintaining a normal diet.
We know from previous research in rhesus monkeys that there are significant longevity benefits to long-term sustained calorie restriction.
Compared to monkeys on a calorie-restricted diet for 20+ years, monkeys on a normal diet had a 2.9 times increased risk of disease, and a threefold increased risk of death.
But, these monkeys were maintained on a single diet throughout their lives. And until now, it was unclear whether some of these findings held true with periodic (yo-yo) dieting.
