Participants wanted for diet and circadian metabolism study

How does changing the food we eat affect the metabolic systems that control the body’s natural circadian rhythm?

The body’s natural circadian clock is regulated by night and day cycles, temperature, dietary intake and physical activity.

Disruptions to the daily patterns of meal composition and timing are associated with the development of metabolic diseases. The influence of changing dietary intake on the circadian clock is currently unknown. This project will determine how normal circadian rhythms are disrupted in response to diets of different macronutrient composition (i.e. high fat vs. high carbohydrate intake).

What is involved?

• Attending the laboratory on 10 occasions on six separate days over a month period, each up to 2.5 hours in duration that will involve blood sampling, muscle biopsies, measurements of body composition, diet and physical activity.
• Consuming a provided study diet for two x 5 day periods (one of high fat, low carbohydrate, and one of high carbohydrate, low fat), separated by two weeks

Benefits to participation

• Metabolic health profile in the form of an individual report at the conclusion of this study
• Advancing medical research
• 10 days of food provided at no personal cost
• Compensation for your time in the study to offset travel/parking expenses
