The Claim

During moderate energy restriction in overweight, postmenopausal women, resistance training does not significantly alter whole-body nitrogen balance, leucine turnover, synthesis, breakdown, or oxidation, despite preserving fat-free mass.

Description
1 study reviewed
In plain English

Even if overweight, postmenopausal women lift weights while eating fewer calories, their body’s use of protein doesn’t change much—but they still keep their muscle mass.

  1. Study: Resistance Training Preserves Fat‐free Mass Without Impacting Changes in Protein Metabolism After Weight Loss in Older Women

    The study found that lifting weights helped older women keep their muscle while losing weight, but it didn’t change how their bodies used or processed protein — exactly what the claim says.
