Impact of daily behaviour on weight-loss drug effectiveness

Weight Loss Drug Study LogoThis 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) 

You will find more detailed information in the Mounjaro Ozempic Blood Glucose Study Participant Information Sheet.

FAMOUS Study - Help us investigate the heart health benefits of eating fish

Several fresh mackerel in a pileEating fish can protect against heart disease, but also increase blood levels of a chemical associated with unhealthy diets which has been linked to heart disease.

Our study will determine whether this chemical is a cause for concern with those who eat a diet high in fish, or whether fish should be considered a healthy alternative to eating meat-based diets in terms of heart disease.

We are looking for healthy, overweight volunteers, both male and female, with elevated blood lipids, sugar or blood pressure but not on medication, to take part in a dietary intervention study.

Volunteers should be aged between 30 and 65 years old, have a BMI of 25-29.9, have no history of heart disease or other inflammatory diseases, and should not be taking any medication for cholesterol or lipaemia.

We would also ask that volunteers are not taking any dietary supplements.

You will find more detailed information in the FAMOUS Study Participant Information Leaflet.

PROSO-COPD Study - The relationship between dietary protein intake and the prevalence of sarcopenic obesity in adult females with chronic obstructive pulmonary disease (COPD)

The NHS Grampian and Rowett Institute logosAs we get older, we may start to lose muscle tissue and gain more body fat. When this happens at the same time, this could lead to a health problem called sarcopenic obesity.  We have ways to assess whether you are likely to have sarcopenic obesity, by measuring your fat-free body mass, and your body mass index (BMI), although we currently do not have an official clinical definition for sarcopenic obesity. 

Recently we found that eating more protein, from both animal and plant-based  foods, reduces your risk of getting sarcopenic obesity. We also found that those with sarcopenic obesity have a higher risk of a decreased lung function.

In this pilot study we would like to investigate, in more detail, whether the amount of protein you eat in your diet is associated with levels of muscle and fat tissue, and with your lung function

We will do this study in a small group of female participants with chronic obstructive pulmonary disease (COPD). As part of this study, we will ask you to visit us once at the Rowett Institute to measure your dietary intake, your muscle mass and body mass index,  your lung function and to obtain a small blood sample.

For more information, see the PROSO-COPD Study Participant Information Sheet.
