Habitual diet - healthy eating guidelines provided for ethical reasons, no restrictions on the time of eating
Flexitarian diet (FD) will be based on planetary diet recommendations (predominantly plants; pulses and legumes as protein sources, meat and poultry consumed occasionally). Ways to facilitate this diet will be presented in the booklet prepared for them by the PI and a dietitian.
Time restricted eating (TRE) with 6 hour eating window - start and end hour to be an individual choice (some may prefer to consume their meals within an early window, e.g. 10am-4pm, some may prefer to consume their meals later in the day, e.g. 12:00-6pm). However, participants will be asked to be fairly consistent with their choice of their timing of eating hours. During fasting only water will be permitted;
Treatment TRE and FD combined.
