In plain English

Among adults with overweight or obesity, treatment with GLP-1 receptor agonists or incretin-based therapies along with diet and physical activity is associated with an average weight loss of 10.08 kilograms.

See the scientific wording

GLP-1 receptor agonist and incretin-based therapies, when combined with lifestyle interventions including diet and physical activity, are associated with an average reduction of 10.08 kg in body weight among adults with overweight or obesity, based on a meta-analysis of eight randomized controlled trials, indicating a clinically meaningful benefit for weight management despite high variability across study contexts.

Why this might work

The drug activates brain signals that reduce hunger and slow stomach emptying, causing people to eat less. At the same time, the body switches from burning sugar to burning fat for energy, especially when calories are limited. This shift increases fat breakdown and ketone production, while exercise helps keep muscle from breaking down. The result is a sustained loss of fat mass without a proportional drop in metabolism.

  1. Study: GLP-1RA- and Incretin-Based Therapies Within Lifestyle Interventions for Adults with Overweight or Obesity: A Systematic Review and Meta-Analysis

    When people with extra weight take GLP-1 medications and follow a healthy diet and exercise plan, they typically lose about 10 kilograms — and this study found exactly that. It’s a real and helpful weight loss, even if results vary a bit from person to person.
