Should I eat 1g of protein per pound of bodyweight?

Meta-analyses converge on 1.6 g/kg as the plateau for muscle protein synthesis in trained adults.

Our read is Partially Supported. The core mechanism holds and the direction is right, but the popular framing tends to overrun what the trials actually show. With a developing evidence base (74/100) and a working majority (72% consensus), eating 1g of protein per pound of bodyweight is reasonable for the right person at $80/month — just calibrate the expectation to the data, not the marketing.

Pulled the public claims about eating 1g of protein per pound of bodyweight from proponents on file (a tracked voice and a tracked voice) and weighed them against the more cautious voices in the field, then cross-checked each against the primary trial and cohort literature and the prevailing clinical guidance. We grade the claim against what the human evidence actually supports, not against how confidently it is stated.

• 01Expert consensus: 72% — a working majority among the voices we track.
• 02Evidence strength: 74/100, which we read as a developing evidence base.
• 03Direction of effect: real, but smaller than the popular framing of eating 1g of protein per pound of bodyweight implies.
• 04Best-supported slice: a specific population or protocol carries most of the signal; generalizing past it is where claims fray.
• 05Weakest link: long-term and hard-outcome data lag the mechanistic and short-term findings.
