Impact of daily behaviour on weight-loss drug effectiveness

This study aims to understand how day-to-day behaviours such as meal timing, physical activity, sleep, and medication use, affect short-term changes in blood glucose levels in people who are using Mounjaro® (tirzepatide) or Ozempic® (semaglutide).

While these medications are effective in supporting blood glucose control and weight management, there is limited evidence on how daily behaviours may influence their effectiveness in real-world settings.

We will collect information on food intake, medication timing, sleep, physical activity, and blood glucose levels over a 7-day period in everyday (free-living) settings.

The findings from this study may offer preliminary insights into how lifestyle behaviours influence medication response and could help inform future research and the development of more tailored support for people using Mounjaro® or Ozempic®.

You may be eligible to take part if you:

• Are 18-75 years old
• Are currently taking Mounjaro® or Ozempic®
• Are fluent in English and able to give informed consent
• Have access to a smartphone (to use the Google Fit app)
