A study involving nearly 1,000 mice found that calorie restriction extends lifespan, but weight loss and metabolic changes aren't the primary drivers of this effect. Instead, immune health, genetics, and physiological indicators of resilience appear to play a more significant role in the relationship between calorie restriction and longevity. This study contradicts previous assumptions about the mechanisms underlying the longevity benefits of calorie restriction.
