Experts warn protein restriction could harm older adults and GLP-1 patients

Researchers have recently suggested that limiting dietary protein might improve metabolic health and extend lifespan, a claim highlighted in a review paper in Cell Press Blue.

Nutrition specialists cautioned that such advice could be dangerous for older adults, people with sedentary lifestyles, and individuals taking GLP-1 weight‑loss medications, warning of serious health risks.

Stuart Phillips, a professor of kinesiology, dismissed the study as a "beautiful mouse story" being marketed as human guidance, noting that low protein intake in people over 65 is linked to poorer outcomes rather than benefits.
