✓Well SupportedStrength training and protein ingestion independently increase muscle protein synthesis, and performing both together stacks these benefits.✓Well SupportedConsuming double the Recommended Dietary Allowance (RDA) of protein makes a significant difference in muscle maintenance compared to the RDA alone.✓Well SupportedMaintaining muscle mass and activity levels is crucial for healthspan, as invalidity negates lifespan benefits.◐Partially SupportedThe relationship between protein intake and health during aging in humans may differ from that in mice.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The mortality benefit of a high protein diet outweighs its detriment around age 50.

◐Partially SupportedSarcopenia and osteoporosis are prevalent in individuals over 75, affecting at least 80% of this age group and leading to a significant decline in activity levels.

◐Partially SupportedOptimal protein intake strategies may change throughout life, with different goals such as maximizing size and strength versus slowing aging.

◐Partially SupportedAll-cause mortality is an important metric for longevity, and healthspan metrics may be equally important.

?Limited ResearchIt is uncertain whether controlled studies exist where individuals ate low protein and performed resistance training late in life.

◐Partially SupportedLow protein intake is beneficial for all-cause mortality up to age 65, after which higher protein intake is associated with lower all-cause mortality.

◐Partially SupportedThere is a camp in the aging field that argues low protein intake is the optimal nutritional strategy for aging and healthspan.

◐Partially SupportedIn individuals over 65, protein deficiency is associated with a significant difference in muscle mass, frailty, and poor outcomes.

◐Partially SupportedIn mice, diets with lower protein content are generally associated with longer lifespans, but one study showed the longest lifespan with a diet that was ad libitum and 40% protein.

◐Partially SupportedProtein intake alone can make a difference in muscle health.

✕Not SupportedLow protein intake in later life is unlikely to confer any healthspan benefits.

◐Partially SupportedBeing under-muscled has severe metabolic consequences, as muscles are the primary sink for glucose and crucial for glucose tolerance and homeostasis.
