The Claim

In overweight and obese women aged 60–75, a higher protein diet (1.28 g/kg/day) during resistance training significantly increased adiponectin levels by 52.4% and decreased leptin levels by 26.5% compared to a higher-carbohydrate diet, which increased adiponectin by −27.9% and leptin by 43.8%.

In plain English

In overweight and obese women aged 60–75, consuming a higher protein diet during resistance training raised adiponectin levels by 52.4% and lowered leptin levels by 26.5%, while a higher-carbohydrate diet lowered adiponectin by 27.9% and raised leptin by 43.8%.

See the scientific wording

In overweight and obese women aged 60–75, a higher protein diet (1.28 g/kg/day) during resistance training significantly increased adiponectin levels by 52.4% and decreased leptin levels by 26.5% compared to a higher-carbohydrate diet, which increased adiponectin by −27.9% and leptin by 43.8%, suggesting improved metabolic and appetite regulation.

Why this might work

Eating more protein while doing strength training causes muscle to stay strong and burn fat more efficiently, which signals fat cells to release more adiponectin and less leptin. This makes the body feel fuller, use fat for energy instead of storing it, and improves how it responds to insulin.

    In older overweight women, eating more protein while doing strength training made their body’s appetite and metabolism hormones improve, while eating more carbs made those hormones get worse — exactly what the claim says.
