Primary Outcome Measures

Name	Time	Method
Metabolic health (Oral glucose tolerance test, OGTT)	120 minutes	Fasting and postprandial blood insulin responses on next morning between trials

Secondary Outcome Measures

Name	Time	Method
HRV	Baseline	Heart rate variability on next morning between trial
Inflammation	Baseline	Fasting inflammatory biomarkers (IL-6, TNF-a, CRP) on next morning between trials
Blood pressure	120 minutes	Changes in blood pressure (systolic and diastolic blood pressure) on next morning between trials
Visual analogue scale (VSA)	120 minutes	Changes in VAS from 0-100 mm (e.g., appetite \& mood, etc.) on next morning between trials
Substate oxidation	120 minutes	Lipid and carbohydrate oxidation during OGTT between trials
Appetite (lunch intake)	30 minutes	Ab libitum energy intake on next morning by the end of trial
Gut hormones	120 minutes	Changes in blood gut hormones responses on next morning (e.g., GLP-1, PYY and GIP) between trials
