The Claim

In overweight and obese women aged 60–75, a 14-week supervised resistance training program combined with a higher protein diet (1.28 g/kg/day) resulted in significantly greater reductions in fat mass (−10.2%) and body fat percentage (−6.3%) compared to a higher-carbohydrate diet (−5.9% and −4.3%, respectively) or exercise alone (−2.7% and −2.0%), while preserving fat-free mass and resting energy expenditure.

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Among overweight and obese women aged 60 to 75, a 14-week program of supervised resistance training and a higher protein diet led to greater reductions in body fat and body fat percentage than a higher-carbohydrate diet or exercise alone, without loss of muscle mass or resting energy expenditure.

See the scientific wording

In overweight and obese women aged 60–75, a 14-week supervised resistance training program combined with a higher protein diet (1.28 g/kg/day) resulted in significantly greater reductions in fat mass (−10.2%) and body fat percentage (−6.3%) compared to a higher-carbohydrate diet (−5.9% and −4.3%, respectively) or exercise alone (−2.7% and −2.0%), while preserving fat-free mass and resting energy expenditure.

Why this might work

Eating more protein while doing strength training keeps muscle from breaking down during weight loss, which keeps metabolism high. The protein also makes the body feel fuller and signals fat cells to release chemicals that help burn fat instead of storing it. Strength training directly activates muscle-building pathways and improves how nerves control muscles, ensuring the body burns fat instead of losing muscle.

    In older women who are overweight, doing strength training and eating more protein helped them lose more body fat than just exercising or eating more carbs — and they kept their muscle and metabolism the same.
