The Claim

In overweight and obese women aged 60–75, a higher protein diet (1.28 g/kg/day) during resistance training does not reduce resting energy expenditure, while such diets are associated with metabolic slowdown during weight loss.

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

In overweight and obese women aged 60–75, consuming 1.28 grams of protein per kilogram of body weight per day during resistance training does not lower resting energy expenditure, whereas higher protein diets typically lower resting energy expenditure during weight loss.

See the scientific wording

In overweight and obese women aged 60–75, a higher protein diet (1.28 g/kg/day) during resistance training did not reduce resting energy expenditure, whereas such diets often cause metabolic slowdown during weight loss, suggesting protein intake may help preserve metabolic rate.

Why this might work

Eating more protein while losing weight keeps muscle from breaking down, and since muscle burns more calories at rest than fat, the body continues to use the same amount of energy even when losing weight.

  1. Study: Effects of Adherence to a Higher Protein Diet on Weight Loss, Markers of Health, and Functional Capacity in Older Women Participating in a Resistance-Based Exercise Program

    When older women ate more protein and did strength training while losing weight, their bodies kept burning calories at the same rate—unlike most diets that slow down metabolism. This suggests eating more protein helps keep your metabolism steady while losing fat.
