Primary Outcome Measures

Name	Time	Method
<br> 1. Adherence to TRE will be measured by asking participants to complete a questionnaire on how many days they completed the intervention. Adherence will be monitored weekly for 6 weeks, then a final adherence rating taken at week 12.<br> 2. Estimates of effect size for future randomised trials, will be obtained using the mean weight change of TRE at 6 weeks and 3 months<br>

Secondary Outcome Measures

Name	Time	Method
<br> 1. Weight is measured using digital scales in kilograms at the baseline visit, weeks 1, 6 and 12. Self-reported weight will be asked at weeks 2-5.<br> 2. Blood Pressure is measured using an Omron blood pressure monitor at the baseline visit and week 12<br> 3. Lipid profile measured using a blood sample given by the participant at the baseline visit and week 12<br> 4. Difficulty adhering to TRE and hunger ratings are measured on a questionnaire weekly from baseline to week 6, then again at week 12<br> 5. Helpfulness of the intervention, TRE difficulty, readiness to continue, 8 hour eating time frames and ratings of hunger will be measured through participant feedback every week for 6 weeks and at week 12. Recommending TRE to friends will be asked at week 12. Participants will have the opportunity to use free text to give feedback about barriers and facilitators of TRE at week 1 and 6.<br>
