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

Secondary Outcome Measures:
  • Serum insulin concentration [ Time Frame: 2 hour ] [ Designated as safety issue: No ]
    2 hour area under the curve for serum insulin following breakfast consumption

  • Plasma glucose-dependent insulinotropic peptide concentration [ Time Frame: 2 hour ] [ Designated as safety issue: No ]
    2 hour area under the curve for plasma glucose-dependent insulinotropic peptide following breakfast consumption

  • Plasma glucagon-like peptide-1 concentration [ Time Frame: 2 hour ] [ Designated as safety issue: No ]
    2 hour area under the curve for plasma glucagon-like peptide-1 following breakfast consumption

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

Enrollment: 10
Study Start Date: May 2012
Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
Breakfast consisting of milk-based porridge with a normal calcium content.
Experimental: High-Calcium
As control, but with a high-calcium content.
Dietary Supplement: Calcium
Milk-calcium supplement

Detailed Description:
Participants will be provided with control and high-calcium meals. Insulin, appetite, glucagon-like peptide-1 and glucose-dependent insulinotropic peptide responses will be assessed, along with rates of substrate oxidation.
