Macro partitioning
Protein restriction, specifically methionine restriction, increases maximum lifespan in rodents by approximately 20%, potentially accounting for half of the life-extending effects of caloric restriction.
While animal studies show that restricting protein, especially methionine, can extend lifespan, this is not yet recommended for humans. More research is needed to determine if this is safe or beneficial for people.
GoodSupportsHIGH confidence
protein restriction increases maximum lifespan by roughly 20%... methionine restriction increases longevity... methionine restriction might account for most or all of the life-extending benefits of protein restriction.
Why this rating
Strong evidence in rodents; no human longevity data.
