Adherence
Resistance exercise combined with caloric restriction is the most effective non-pharmacological strategy for preserving skeletal muscle mass and strength during weight loss.
Do not rely on diet alone. Incorporate resistance training into your weight loss plan to prevent muscle loss and maintain strength.

WLEX [weight loss combined with exercise] prevented reductions in lean mass (DXA) and strength that were observed in the WL [weight loss] group.

More from this paper
- Current pharmacological treatments for obesity, including incretin-based therapies (semaglutide, tirzepatide), result in significant skeletal muscle loss (approx. 7-10% of lean mass) alongside fat loss.Strong
- High-quality weight loss, defined as maximizing fat loss while preserving skeletal muscle mass, is critical for maintaining metabolic health, insulin sensitivity, and long-term weight maintenance.Good
