Primary Outcome Measures:
  • Total fat oxidised during 60 min of exercise (g). [ Time Frame: 1 hour ] [ Designated as safety issue: No ]
    Assessed by indirect calorimetry

Secondary Outcome Measures:

  • Serum Insulin Concentration [ Time Frame: 2 hour ] [ Designated as safety issue: No ]
    2 h area under the curve for serum insulin following breakfast consumption

  • Subjective appetite ratings [ Time Frame: 3 hour ] [ Designated as safety issue: No ]
    Subjective ratings of appetite assessed by visual analogue scales.
