Macro partitioning

Recreational athletes can maintain endurance and muscular strength performance on predominantly plant-based diets (whole food or meat alternatives) compared to an omnivorous diet, provided protein and carbohydrate intake meet standard sports nutrition recommendations.

If you are a recreational athlete, you do not need to eat meat to maintain your running speed or strength. You can switch to a whole-food plant-based diet or use plant-based meat alternatives (like Beyond or Impossible burgers) as long as you eat enough protein (0.8-1.2g/kg/day) and carbohydrates (3-5g/kg/day). Ensure you are eating enough total calories and maintaining your training routine.

Our findings suggest recreational athletes can maintain athletic performance on both an omnivorous diet and two diets that are predominately plant-based.

Why this rating

Randomized crossover trial with a relatively small sample size (n=22) and short duration (4 weeks per diet), limiting generalizability to elite athletes or long-term adaptations.
