Treatment and study plan

Breakfast & exercise

Drug

1859 kJ breakfast vs fast, exercise at 60% maximum aerobic capacity to expend 1859 kJ.

Primary outcomes

  1. Energy balance

    Time frame: 24 h

    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 outcomes

  1. Blood glucose

    Time frame: 1.5 h area under the curve, post-consumption of a liquid snack

  2. Serum insulin

    Time frame: 1.5 h area under the curve, post-consumption of a liquid snack

  3. 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

    Participants will be asked to complete visual analogue scales (VAS).

  4. 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

    Reaction time, short-term memory, speed of processing, attention.

  5. Mood

    Time frame: 1.5 h area under the curve, post-consumption of a liquid snack and following an ad libitum test meal

    Participants will be asked to complete visual analogue scales (VAS).

  6. Energy expenditure

    Time frame: 1.5 h mean following a liquid snack

    Measured by indirect calorimetry
