Conditions

Treatment of glucose homeostasis in people at risk of type 2 diabetes. Nutritional, Metabolic, Endocrine

Interventions

All participants completed two 6-day interventions with a wash-out of 7 days. Each 6-day intervention consisted of an initial 3-day habitual dietary intake phase (Non-TRE i.e. the control condition),
Early-TRE) or late (12pm - 8pm
Late-TRE). In which order a participant followed the two 6-day interventions was randomised. During TRE phase, participants were provided with foods to follow a eucaloric energy intake. During the non

Design outcomes

Primary

MeasureTime frame
Glucose homeostasis - assessed using continuous glucose monitoring. Specific outcomes include 3-day average of mean 24h glucose, glucose area under the curve and glycaemic variability markers.

Secondary

MeasureTime frame
Fasted cardio-metabolic blood markers (insulin, HOMA-IR, ADIPO-IR, cholesterol) taken before and after each 3-day TRE phase.
