The Claim

In adults with overweight or obesity undergoing 6 months of caloric restriction, a higher self-selected protein intake (79 g/day or 1.0 g/kg/day) is associated with a 0.6% reduction in lean body mass loss compared to a 1.2% reduction in lean body mass loss among those with lower protein intake (58 g/day).

In plain English

Among adults with overweight or obesity who reduce calorie intake for six months, those who eat more protein lose less lean body mass than those who eat less protein.

See the scientific wording

In adults with overweight or obesity undergoing 6 months of caloric restriction, self-selected higher protein intake (79 g/day or 1.0 g/kg/day) is associated with a 0.6% reduction in lean body mass loss compared to 1.2% loss in those with lower protein intake (58 g/day), suggesting that increased protein consumption may help preserve lean tissue during weight loss.

Why this might work

When more protein is eaten, the body gets more building blocks for muscle, which keeps muscle from breaking down even when calories are low. The muscles use these building blocks to make new proteins and stop breaking down old ones, so less muscle is lost.

  1. Study: Higher protein intake during caloric restriction improves diet quality and attenuates loss of lean body mass

    When people with extra weight eat fewer calories, those who naturally eat more protein (about 79 grams a day) lose less muscle than those who eat less protein (about 58 grams a day), and this study confirms that pattern.
