First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at whether a high-protein vegetarian diet, combined with resistance training, can help older adults maintain muscle mass. 110 healthy participants aged 55+ followed either a vegetarian or omnivorous high-protein diet for 12 weeks, all doing the same exercise program. Researchers measured changes in protein intake and lean muscle mass to see if the plant-based approach works as well as the meat-based one.

Active substance

high-protein vegetarian diet and resistance exercise program

What this could lead to

If successful, this could show that a plant-based diet combined with exercise is a practical way for older adults to preserve muscle mass and stay active.

What could go wrong

This is a small, completed study comparing two diets, not a treatment for a disease. Results may not apply to everyone, and the plant-based diet might not match the protein quality of an omnivorous diet.
