Should You Restrict Protein To Extend Your Lifespan?



โฃ

People like to ๐˜จ๐˜ณ๐˜ข๐˜ท๐˜ช๐˜ต๐˜ข๐˜ต๐˜ฆ ๐˜ต๐˜ฐ ๐˜ฆ๐˜น๐˜ต๐˜ณ๐˜ฆ๐˜ฎ๐˜ฆ๐˜ด, and diet is no exception. We know that chronically overeating shortens lifespan, so therefore chronically undereating or mimicking it with protein restriction should lengthen lifespan, ๐˜ณ๐˜ช๐˜จ๐˜ฉ๐˜ต?โฃ

We are ๐˜ค๐˜บ๐˜ค๐˜ญ๐˜ช๐˜ค๐˜ข๐˜ญ beings. We thrive when we rotate between periods of feeding and fasting; periods of growth and reproduction; with periods of repair and recycling. Chronic overeating and undereating are problematic, with the ๐˜ฐ๐˜ฑ๐˜ต๐˜ช๐˜ฎ๐˜ข๐˜ญ ๐˜ด๐˜ต๐˜ข๐˜ต๐˜ฆ ๐˜ฃ๐˜ฆ๐˜ช๐˜ฏ๐˜จ ๐˜ช๐˜ฏ ๐˜ต๐˜ฉ๐˜ฆ ๐˜ฎ๐˜ช๐˜ฅ๐˜ฅ๐˜ญ๐˜ฆ.โฃ

  • The Blue Zones have a ton going on that facilitate living longer, like greater mental health and social support. Thereโ€™s also ๐˜ค๐˜ฐ๐˜ฏ๐˜ต๐˜ณ๐˜ฐ๐˜ท๐˜ฆ๐˜ณ๐˜ด๐˜บ over whether their longevity data is even legit, with some reports suggesting that the birth certificates are fake or otherwise invalid.โฃ

  • The calorie deficits used with fasting mimicking diets are doing most of the heavy work, as we see similar metabolic changes observed from eating low-protein in bodybuilders eating high-protein diets while getting super lean for contest preparation.โฃ

โฃ

  • The animal studies are very inconsistent. Ignoring the fact that mice are not small humans due to vastly different metabolisms, the same โ€œlongevityโ€ diet given to different strains of mice causes vastly different effects on lifespan, with most showing it to actually shorten lifespan.โฃ

In contrast to all this weak mechanistic and observational data, we have a mountain of clinical, observational, and mechanistic evidence showing that protein is critically important for muscle growth and retention with aging โ€” and that the age-related loss of muscle mass is a leading cause of reduced quality of life and premature death. โฃ

Accordingly, ๐ข๐ญ ๐ฆ๐š๐ค๐ž๐ฌ ๐ง๐จ ๐ฌ๐ž๐ง๐ฌ๐ž ๐ญ๐จ ๐ซ๐ž๐ฌ๐ญ๐ซ๐ข๐œ๐ญ ๐ฉ๐ซ๐จ๐ญ๐ž๐ข๐ง ๐ข๐ง๐ญ๐š๐ค๐ž ๐Ÿ๐จ๐ซ ๐ฅ๐จ๐ง๐ ๐ž๐ฏ๐ข๐ญ๐ฒ, since that increases the risk of dying prematurely.

Moreover, even if lifespan was increased, would it be worth impaired physical function, reduced quality of life, and the fear of falls and fractures?โฃ
