Keep taking it, keep losing it. Two large Epic Research studies found that adults who stayed on GLP-1 medications for two years largely maintained the weight they lost in year one — with tirzepatide outperforming semaglutide and non-diabetic patients faring better than those with diabetes. Full weight regain was rare, affecting only 1%–5% of patients.
Two new Epic Research studies drawing on over 310 million patient records confirm what many clinicians suspected: continued GLP-1 use equals continued benefit. Adults who lost at least 5 lbs in their first year on semaglutide or tirzepatide and stayed on the medication largely held onto that loss through year two — and many kept losing.
Patients without diabetes fared better, with about 53% maintaining weight loss at two years on either drug. Among those with diabetes, 47.3% on tirzepatide and 37.7% on semaglutide maintained their loss. Tirzepatide consistently showed less weight regain than semaglutide across both groups. Full return to baseline weight was uncommon, occurring in just 1%–5% of patients.
Key Takeaways:
Why it matters: These findings give clinicians concrete data to counsel patients on the long-term nature of GLP-1 therapy — and underscore the urgent need for consistent insurance coverage to prevent medically harmful weight regain.
