Anticipation of meal time in humans

Would you like to participate in one of our research studies looking into how our metabolism is affected by meal timing?

This study aims to test whether we can anticipate the arrival of a regular meal. This might help us to understand complex inter-relationship between diet and healthy physiology and the implications of keeping to a regular schedule in meal timing.

The study will last approximately 10 days. You will be asked to visit the centre up 5 times. The first visit would be to establish your eligibility for the study. This will last approximately 3 hours; however, this visit may be split. The next 2 visits will be to collect and check equipment and data for the pre-study period. The next visit will be the 9 night laboratory stay. During this visit we will be taking saliva and blood samples and asking to fill out some questionnaires. You will need to stay awake for 37 hours during this residential stay.

You will be screened over the telephone in the first instance to assess your suitability and to be advised of all other restrictions; if you wish to participate and the results from the telephone screen identify you as suitable, you will be invited to the Clinical Research Facility for a screening visit. For the initial visit you must bring in your passport.
