Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with BMI ≥25 who have started or plan to start a GLP-1 receptor agonist within the past or next two months are ideal candidates.

Probably not a fit

People who are pregnant, intend to become pregnant, are unable to participate in regular exercise, have an implanted pacemaker, or have other safety concerns are unlikely to benefit from participation.

What this trial studies

This interventional program provides adults who recently started or plan to start GLP-1 receptor agonist therapy with a smartwatch that measures activity and body composition and delivers exercise reminders alongside general exercise guidance. Participants use the device during early treatment with liraglutide, semaglutide, tirzepatide, or retatrutide while investigators monitor changes in muscle mass and strength. Key inclusion criteria include age ≥18 and BMI ≥25 kg/m2, and exclusions include pregnancy, implanted pacemaker, or inability to participate in regular exercise. The study is conducted at the Diabetes Research Center at Massachusetts General Hospital in collaboration with Samsung.

Why it matters

Potential benefit: If successful, this approach could help people on GLP-1 medications maintain muscle mass and strength while losing weight.

How similar studies have gone: Prior studies show that exercise and activity-tracking can help preserve muscle during weight loss, but pairing wearable-guided programs specifically with GLP-1 therapies is relatively new.

   a. Potential participants switching GLP1-RA therapies due to inadequate response to a prior treatment will be eligible for enrollment
3. Able to provide informed consent

Exclusion Criteria

1. Current pregnancy (positive urine hCG) or plans to become pregnant in the next 6 months
2. BMI \<25 kg/m2 at the time of screening
3. Unable to participate in a regular physical exercise program
4. Implanted pacemaker
5. Any factors that, in the opinion of the principal investigator, would interfere with the safe completion of the study
