GendAge Study

Are you interested in helping us understand how age and gender affect weight loss?

We’re conducting a ground-breaking study to explore how sex hormones influence dieting outcomes in men and women as they age. If you are willing to help us advance women’s health research by participating in a six-week diet programme with all food provided, please contact the study research team for more information.

We are looking for healthy men and women who are:

• Aged 18-40 or 55-65

• Living with overweight or obesity (BMI 27-45 kg/m2 - we can measure this for you at the screening visit)

What is involved?

• We will assess your body composition and energy expenditure

• We will analyse your blood and fat tissue, as well as urine samples

• You will be asked to consume a specially-designed weight-loss diet with all foods prepared at the Rowett Institute by dietetic staff

• We will equip you with wearable devices to monitor your glucose and physical activity levels over the course of the study
