Primary Outcome Measures

Name	Time	Method
Fat oxidation will be estimated with the oxygen consumption (VO2) and the carbon dioxide excretion (VCO2) values obtained through indirect calorimetry, using the Frayn (1983) equation.[ At baseline and on day 5 of the test meal consumption (once a day)];Energy intake assessed by food diary[ At baseline (the week before participating in the study) and 24 h after the consumption of the last test meal on day 5]

Secondary Outcome Measures

Name	Time	Method
Respiratory exchange ratio will be assessed by indirect calorimetry[ Baseline and on day 5 of the high glycemic and the low glycemic index sessions]
