Use of blockbuster anti-obesity drugs like Wegovy and Zepbound is growing, with about 1 in 8 adults in the U.S. saying they currently take the medications. But experts say the drugs alone aren't the answer. It takes lifestyle changes, too, including a healthy diet, physical exercise, adequate sleep and stress management to reap the biggest benefits from GLP-1s. The clinical trials of the drugs included structured lifestyle changes, which are advised along with every prescription. Experts say users should eat protein, drink water and exercise for about an hour each day.

Prices are falling for the popular obesity treatments Wegovy and Zepbound, but steady access to the drugs remains challenging. Reduced monthly costs for uninsured patients still amount to around $500. That can put the drugs out of reach for many. Coverage also continues to shift or restrict how patients get prescriptions. Doctors say the patchy coverage and costs force them to get creative in treating patients. But there's hope that prices for the injectable drugs may fall more in the future, especially once pill versions enter the market.
