The Claim

A daily protein intake of 0.7 to 1.0 gram per pound of body weight is sufficient to support muscle maintenance and growth in resistance-trained adults.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Resistance-trained adults who consume 0.7 to 1.0 grams of protein per pound of body weight each day maintain and build muscle.

See the scientific wording

A daily protein intake of 0.7 to 1.0 gram per pound of body weight is sufficient to support muscle maintenance and growth in resistance-trained adults.

Why this might work

When muscles are stretched and pulled during weight training, the physical force triggers molecular signals that tell muscle cells to build more contractile proteins. Amino acids from daily protein intake are used as building blocks to assemble these proteins. As long as enough protein is consumed each day, the muscle keeps adding new contractile material with each training session, leading to stronger and larger muscles over time.

What the research says

2 studies

  1. Study: Resistance training increases myofibrillar protein synthesis in middle-to-older aged adults consuming a typical diet with no influence of protein source: a randomized controlled trial

    People who lift weights and eat about 0.45 grams of protein per pound of body weight still built muscle when they exercised — so eating more (0.7 to 1.0 grams) should work just fine or even better.

  2. Study: Effects of daily protein intake frequency during 8 weeks of resistance training on lean mass and strength adaptations: a randomized non-controlled clinical trial.

    This study showed that resistance-trained men who ate protein either 3 or 5 times a day still gained the same amount of muscle and strength — meaning eating enough protein each day (not how you spread it out) is what matters. The amount they ate fits right in the 0.7–1.0 grams per pound range.
