The Claim

In overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, a weight loss intervention combining caloric restriction and physical activity increases the lean mass to fat ratio by 0.40.

Source: Reduced adipose tissue with limited loss of lean mass after weight loss: results from the Prostate Active Lifestyle Study.

In plain English

In overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, a weight loss program that reduces calories and includes physical activity increases the ratio of lean mass to fat mass by 0.40.

See the scientific wording

In overweight or obese men aged 67 with early-stage prostate cancer on active surveillance, a weight loss intervention combining caloric restriction and physical activity increases the lean mass to fat ratio by 0.40, indicating a clinically meaningful improvement in body composition that may reduce metabolic and cancer-related risks.

Why this might work

When a person eats fewer calories and moves more, the body burns fat for energy while protecting muscle tissue. This causes fat to shrink and muscle to stay the same size, improving the ratio of muscle to fat.

  1. Study: Reduced adipose tissue with limited loss of lean mass after weight loss: results from the Prostate Active Lifestyle Study.

    In older men with prostate cancer who are overweight, losing weight through diet and exercise helped them lose mostly fat while keeping their muscle, which improved their muscle-to-fat ratio by exactly 0.40 — a meaningful and healthy change.
