The Claim

When young, trained men consume protein in either three or five meals per day with equal total daily protein intake, both dietary patterns are associated with similar increases in lean mass and knee extension strength over an eight-week period of resistance training.

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

What the research says

Supports is higher

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

In plain English

If you're a young guy who already trains regularly and you spread your protein across either three or five meals a day — as long as the total protein is the same — you'll likely gain about the same amount of muscle and strength either way.

Consuming protein in three or five meals per day, with equal daily total intake, is associated with similar increases in lean mass and knee extension strength over eight weeks of resistance training in young, trained men.

What the research says

1 study
  1. 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.

    The study gave two groups of trained guys the same total amount of protein each day, but one group ate it in three meals and the other in five meals. After eight weeks of lifting weights, both groups got just as strong and gained about the same amount of muscle — so how you spread out your protein doesn’t matter as long as you eat enough total.
