Summary
A May 8 review led by more than 20 protein scientists said many protein-product claims overstate benefits, especially around fullness, weight loss and simple gram-based labeling.
The paper argues protein quality matters alongside quantity, with amino acid profile, digestibility and bioavailability differing by source; animal proteins generally score higher than plant proteins on DIAAS.
For weight loss, the authors said intake above the 0.8 g/kg/day guideline can help preserve lean mass during calorie restriction, but targets tied to body weight work better than adding a flat 20 grams.
The review also found insufficient evidence that protein is the most filling nutrient, saying appetite responses vary by person, food source and eating occasion.
That challenge lands in a fast-growing market: Americans spent $50 billion on protein snacks last year, with sales projected to double by 2032 even as some bars contain artificial sweeteners and dyes.
