The Claim

During caloric restriction, resistance training is associated with a higher proportion of weight loss derived from fat mass compared to aerobic exercise or no exercise.

In plain English

When people reduce their calorie intake, those who do resistance training lose a greater share of their weight as fat compared to those who do aerobic exercise or no exercise.

See the scientific wording

During caloric restriction, resistance training is associated with a higher proportion of weight loss derived from fat mass compared to aerobic exercise or no exercise, indicating more favorable body recomposition.

Why this might work

When someone lifts weights while eating fewer calories, their muscles sense the tension and build more protein, preventing muscle loss. The extra muscle burns more energy at rest and pulls fat from the body, especially from around the organs, so most of the weight lost comes from fat instead of muscle.

  1. Study: Resistance training as a key strategy for high-quality weight loss in men and women

    When people diet, lifting weights helps them lose more fat and keep or even gain muscle, while cardio or no exercise makes them lose muscle too. So lifting weights is better for getting lean without losing strength.
