Honest limits
What this study does not prove.
The review found small differences in muscle mass and no clear difference in strength or performance, so it does not make animal protein universally necessary.
Kris's practical takeaway
Here's what to do with it.
You can build a strong plant-based plan, but protein amount, source variety, leucine content, and daily consistency may need extra attention.
Ways to use it

Plant protein can work, but plan it

Questions this research helps answer.
Diet muscle-retention answer
How do you avoid losing muscle while dieting?
Lift while you diet. In a 2025 meta-analysis of 25 randomized trials in adults with overweight or obesity, adding resistance exercise to dietary weight loss protected fat-free mass (SMD 0.40), increased fat-mass loss (SMD -0.36), and improved strength (SMD 2.36), while bodyweight loss was not meaningfully different (-0.32 kg between groups). Use those findings as a guide: keep lifting, hit a realistic protein floor, avoid crash dieting, and track strength instead of only scale weight.
Protein source answer
Is plant protein as good as animal protein for muscle?
Plant protein can work, but the plan may need more precision. Total protein, source variety, protein quality, and resistance training matter more than arguing about one perfect food.
