Abstract

A total of 132 participants, or 64.4%, achieved at least 5% weight loss after 6 months of anti-obesity medication treatment.

  • Phentermine was associated with the highest prevalence of achieving ≥5% weight loss compared to other medications, except for liraglutide.
  • Specific weight loss rates after 6 months were: 87.2% for phentermine, 67.7% for phentermine/topiramate, 58.1% for liraglutide, 35.3% for naltrexone/bupropion, 75% for lorcaserin, and 50% for orlistat.
  • Significant differences in body weight, body mass index, and body fat mass were observed among the different anti-obesity medication groups.
  • No significant changes were reported in waist circumference, skeletal muscle mass, percentage body fat, or visceral fat area across the groups.
  • The findings suggest that various can effectively induce weight loss without significant impacts on muscle mass.
