Weight‑Loss Pills Work for Most People, But Women Lose More

The new study shows that medicines used to drop weight, like Ozempic and Trulicity, help people of many ages, races and body sizes. Researchers at Johns Hopkins looked through almost 20, 000 patients from 64 trials to see how the drugs performed. The pills work by mimicking a hormone that tells the brain “I’m full. ” They also help the pancreas release insulin. Because they are expensive and in high demand, doctors want to know who gets the most benefit. The main finding is that the drugs are equally effective for people who are younger or older than 65, have a high or low body‑mass index (BMI), and come from different racial or ethnic backgrounds. Even people with different starting blood‑sugar levels saw similar results.A clear difference appears between men and women. Women who took the medication lost an average of 11 % of their body weight, while men lost about 7 %. Scientists think this gap could be due to how women’s bodies process the drug, lower starting weights, or hormone interactions like estrogen. The study focused only on GLP‑1 drugs and left out newer combinations such as Zepbound. Most of the trials were funded by industry, which is common in this field. The researchers say these results give doctors and patients confidence that GLP‑1 drugs can be used across diverse groups. They also highlight the need for more studies, especially for people who are under‑represented in clinical trials. The World Health Organization has issued guidelines on using GLP‑1 drugs for obesity, but this new evidence helps clarify how the medicines perform in real life.
