Claim 1 of 3Not checkedA new perspective from LSU's Pennington Biomedical Research Center proposes that protein restriction may promote healthy aging and extend lifespan through a coordinated physiological response connecting cellular nutrient sensing, hormones, the brain and changes throughout the body.View evidenceHide evidence

Claim 2 of 3Not checkedThe perspective, titled 'Protein restriction and the hallmarks of aging: A coordinated physiological adaptive response?', was published in Cell Metabolism and argues that the effects of protein restriction on metabolism, glucose regulation, energy expenditure, growth and food preferences are interconnected components of a broader response to protein scarcity.View evidenceHide evidence

Claim 3 of 3Not checkedThe authors say their framework raises the question of where the longevity benefit is encoded, suggests that FGF21 responsiveness, metabolic changes or appetite shifts could serve as biomarkers, and may help explain differences in response by sex, genetics, age and metabolic health.View evidenceHide evidence
