Should You Restrict Protein To Extend Your Lifespan?



People like to 𝘨𝘳𝘢𝘷𝘪𝘵𝘢𝘵𝘦 𝘵𝘰 𝘦𝘹𝘵𝘳𝘦𝘮𝘦𝘴, 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, 𝘳𝘪𝘨𝘩𝘵?⁣

𝐍𝐎!⁣

We are 𝘤𝘺𝘤𝘭𝘪𝘤𝘢𝘭 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 𝘰𝘱𝘵𝘪𝘮𝘢𝘭 𝘴𝘵𝘢𝘵𝘦 𝘣𝘦𝘪𝘯𝘨 𝘪𝘯 𝘵𝘩𝘦 𝘮𝘪𝘥𝘥𝘭𝘦.⁣

𝐓𝐡𝐞 𝐞𝐯𝐢𝐝𝐞𝐧𝐜𝐞 𝐮𝐬𝐞𝐝 𝐭𝐨 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 𝐩𝐫𝐨𝐭𝐞𝐢𝐧 𝐫𝐞𝐬𝐭𝐫𝐢𝐜𝐭𝐢𝐨𝐧 𝐟𝐨𝐫 𝐥𝐨𝐧𝐠𝐞𝐯𝐢𝐭𝐲 𝐢𝐬 𝐢𝐧𝐜𝐫𝐞𝐝𝐢𝐛𝐥𝐲 𝐰𝐞𝐚𝐤:⁣

  • The Blue Zones have a ton going on that facilitate living longer, like greater mental health and social support. There’s also 𝘤𝘰𝘯𝘵𝘳𝘰𝘷𝘦𝘳𝘴𝘺 over whether their longevity data is even legit, with some reports suggesting that the birth certificates are fake or otherwise invalid.⁣

  • 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.⁣

  • The animal studies are very inconsistent. Ignoring the fact that mice are not small humans due to vastly different metabolisms, the same “longevity” diet given to different strains of mice causes vastly different effects on lifespan, with most showing it to actually shorten lifespan.⁣

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 — and that the age-related loss of muscle mass is a leading cause of reduced quality of life and premature death. ⁣

Accordingly, 𝐢𝐭 𝐦𝐚𝐤𝐞𝐬 𝐧𝐨 𝐬𝐞𝐧𝐬𝐞 𝐭𝐨 𝐫𝐞𝐬𝐭𝐫𝐢𝐜𝐭 𝐩𝐫𝐨𝐭𝐞𝐢𝐧 𝐢𝐧𝐭𝐚𝐤𝐞 𝐟𝐨𝐫 𝐥𝐨𝐧𝐠𝐞𝐯𝐢𝐭𝐲, 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?⁣
