Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Food intake	Food by weight (g) in response to variations in portion served	24-hours intake period
Primary	Energy intake	Food by energy (kcal) in response to variations in portion served	24-hours intake period
Primary	Energy density consumed	Energy density consumed (kcal/g) in response to variations in portion served	24-hours intake period
Secondary	Appetite-regulating hormones	Appetite-regulating hormones, including Glucagon-like-peptide 1 (GLP-1) and ghrelin will be analyzed from plasma from whole blood samples collected while fasted and at 30, 60, 90, and 120 min postprandial. Area under the curve of plasma concentrations will be calculated for each individual appetite-regulating hormone	2-hours measurement period
Secondary	Hunger and fullness	Subjective measures related to hunger, fullness, and prospective consumption will be measured before and after meals via visual analog scales. The range of scores are 0 mm to 100 mm, with higher scores indicating greater feelings of the corresponding measure (e.g. greater hunger). Post-meal measures, adjusted for the corresponding pre-meal measure, will be analyzed as individual outcomes. Area under the curve will also be calculated for each measure.	24-hours measurement period
