Brief Summary

Background: Time-restricted feeding can improve insulin sensitivity, and increase fat oxidation in people with prediabetes independent of weight loss. It may also help people to lose weight. However, it has not been tested in people with type 2 diabetes. Plan of investigation: Participants meeting the eligibility criteria will be randomized to the TRF arm or the continuous eating arm. Both arms with be given a prescribed dietary plan to help them lose 5% of body weight. In the TRF they will permitted to eat between midday and 6pm. In the continuous eating arm they will be allowed to eat between 8am and 11pm. Participants will attend the nutrition clinic every two weeks to be weighed and be given personalized support to help them follow their assigned diet. Prior to starting the diets outcome measures will be taken: Glycaemia will be measured by a glucose tolerance test, and 7-day continuous glucose monitoring. HbA1c will be taken from fasting blood sample. In addition, the fasting sample will be taken for measurement of insulin, lipid profile and inflammatory markers. We will also use questionnaires to assess quality of life, a 3-day food diary to assess compliance to diet especially meal timings. Capillary ketones will also be used to assess whether compliance to the assigned fasting period. Outcome measures will also be taken during 7 days of the second month, and then the final seven days of the last month on the diet. The primary outcome is HbA1c.
