Primary Outcome Measures

Name	Time	Method
Energy expenditure	Time frame is every 30 minutes for four hours following intervention.	Energy expended per minute will be measured using indirect calorimetry.
Appetite	Time frame is every 30 minutes for four hours following intervention.	Appetite will be assessed using a traditional 100-mm visual analog scale (VAS) (3) with opposing anchors (e.g., "extremely hungry" or "not hungry at all") at time points 15, 30, 60, 90, 120, 180 and 240 min. Questions consisted of: "how hungry do you feel at this moment", "how full do you feel at this moment", "how strong is your desire to eat this moment" and "how much food do you think you can eat at this moment." Participants were asked to place an "X" on the 100-mm VAS in the place that pertained to their perceived appetite feelings at each time point." Participants were asked to place an "X" on the 100-mm VAS in the place that pertained to their perceived appetite feelings at each time point. The averages for each time point are taken to represent the feeling of appetitive at a particular time point.
