Primary Outcome Measures:
  • 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.


Secondary Outcome Measures:
  • Blood glucose [ Time Frame: 1.5 h area under the curve, post-consumption of a liquid snack ] [ Designated as safety issue: No ]
  • Serum insulin [ Time Frame: 1.5 h area under the curve, post-consumption of a liquid snack ] [ Designated as safety issue: No ]
  • Subjective appetite ratings [ Time Frame: 1.5 h area under the curve, post-consumption of a liquid snack and following an ad libitum test meal ] [ Designated as safety issue: No ]
    Participants will be asked to complete visual analogue scales (VAS).

  • Cognitive function measurements [ Time Frame: 1.5 h area under the curve, post-consumption of a liquid snack and following an ad libitum test meal ] [ Designated as safety issue: No ]
    Reaction time, short-term memory, speed of processing, attention.

  • Mood [ Time Frame: 1.5 h area under the curve, post-consumption of a liquid snack and following an ad libitum test meal ] [ Designated as safety issue: No ]
    Participants will be asked to complete visual analogue scales (VAS).

  • Energy expenditure [ Time Frame: 1.5 h mean following a liquid snack ] [ Designated as safety issue: No ]
    Measured by indirect calorimetry
