Hormonal

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) including liraglutide, exenatide, semaglutide, and dulaglutide produce statistically significant weight loss in obese individuals, with intervention groups losing 5.1 to 6.16 kg compared to 1.6 to 3.97 kg in control groups.

If you are obese, GLP-1 receptor agonists like liraglutide or semaglutide are proven to help you lose weight significantly more than lifestyle changes alone. These medications work by mimicking a hormone that makes you feel full and slows down digestion. While they are injections, they have been shown to be safe and effective for adults aged 18-65, helping to reduce body fat and improve metabolic health.

GoodSupportsHIGH confidence
individuals lost weight of about minimum of 5.1 kg and maximum of 6.16 kg in the intervention group or those who were observed to use any type of GLP-1Ras as opposed to 1.6 - 3.97 kg lost among those individuals who did not use any type of GLP-1Ras. These results with their respective effect sizes were statistically significant with a P-value of < 0.05.

Why this rating

Based on a systematic review of 20 studies including RCTs, though the review itself is qualitative rather than a meta-analysis.
