Study finds calorie restriction and intermittent fasting extend lifespan in mice

A recent study by Gary Churchill at The Jackson Laboratory found that calorie restriction and intermittent fasting can extend lifespan in mice. The research involved 937 female mice divided into groups with different dietary access. Mice with calorie restrictions or intermittent fasting lived longer than those with unrestricted food access. Notably, mice fasting for two days a week had greater lifespan extensions compared to those fasting for one day. The study also highlighted potential downsides of extreme dietary restrictions, including loss of lean body mass and reduced immunity. These findings suggest a complex relationship between diet and longevity.
