Brief Summary:

Four months of interval walking (IW) training results in substantial weight loss in opposition to energy-expenditure matched continuous walking (CW) training. The reason for this is unclear.

This study will assess if IW leads to greater exercise-induced suppression of appetite and ad libitum food intake compared to CW and no exercise.

Subjects with type 2 diabetes will be included in a crossover, counter-balanced, controlled study, where each subject will undergo three trials. Trials will be identical except the following interventions:

  1. One hour of rest (CON)
  2. One hour of interval walking (repeated cycles of 3 min of fast and 3 min of slow walking; IW)
  3. One hour of continuous walking (CW) matched to IW with regards to energy-expenditure.

After the interventions subjects will undergo a liquid mixed meal tolerance test (450 kCal), with regular measurements of appetite-related hormones (insulin, ghrelin, Leptin, Cholecystokinin, PYY). Three hours into the mixed meal tolerance test, a standardised ad-libitum meal test will be served and intake will recorded. Free-living energy intake via food records will be assessed during the following 32 hours.

Primary Outcome Measures :
  1. Ad-libitum meal energy intake [ Time Frame: Initiated 3 hours after the intervention ]
    Subjects will receive a standardized ad-libitum meal and energy intake will be assessed


Secondary Outcome Measures :
  1. Free-living energy intake [ Time Frame: For 32 hours following the ad-libitum meal. ]
    Subjects will complete diet records for 32 hours following the ad-libitum meal and energy intake will be assessed.

  2. Appetite-related hormones [ Time Frame: Regularly during the 3 hours following the intervention ]
    Appetite-related hormones (insulin, ghrelin, leptin, cholecyctokinin, PYY) will be analysed in blood samples collected regularly during the liquid mixed-meal tolerance test following the intervention

  3. Satiety [ Time Frame: Regular assessments for 36 hours following the intervention ]
    Satiety questionaires will be completed at regular intervals after the intervention
