Abstract

In over half of the studies reviewed, the proportion of reduction ranged between 20% and 50% of total weight lost.

  • Weight loss from glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) is primarily due to reduction.
  • Significant variability exists among studies regarding the impact of these therapies on body composition.
  • Lean body mass loss is observed alongside weight loss from both GLP-1RAs and SGLT2is, similar to effects seen with diet and bariatric surgery.
  • No significant differences were noted between GLP-1RAs and SGLT2is in terms of body composition changes.
  • Attention is needed to strategies that preserve skeletal muscle and enhance physical function during weight loss treatments.
