Energy balance [ Time Frame: 24 h ] [ Designated as safety issue: No ]
Energy balance (kJ/kcal) will be assessed by an ad libitum test meal provided at 5 h minus energy expenditure estimated by indirect calorimetry.
Energy intake [ Time Frame: 24 h ] [ Designated as safety issue: No ]
Energy intake (kJ/kcal) will be assessed by an ad libitum test meal provided at 5 h and food diaries completed for the rest of the day (24 h)
