Eating, sleeping and weight control

Recent research suggests that sleeping patterns (e.g. how much sleep we get and our quality of sleep) can influence what we eat. Studies have shown that poor sleep may increase our desire to eat high energy foods which may promote weight gain and obesity. Our intake of these foods may also be affected by our perceptions of their health and nutritional value.

This study involves two short (40 minute) visits to the University of Sydney and a home study period where you will complete a Food and Sleep diary and wear a wrist device that measures your sleep. You will be reimbursed for your time with a $30 voucher. 

This study has been approved by the human research ethics committee at the RPAH (Protocol No X17-0228 & HREC/17/RPAH/343).


You may be eligible to participate in this study if you:

  • have a BMI of less than 25 or over 30 (calculate your BMI here)
  • not be pregnant or breastfeeding
  • not working night shifts
  • not on a special diet¬†
  • not had bariatric (weight loss) surgery¬†
