Role of Dietary Protein on Satiety, Food Intake and Thermic Effect of Food

September 28, 2020 updated by: Nick Bellissimo, Ryerson University

Role of Dietary Protein in a Familiar Breakfast Meal on Subjective Satiety, Food Intake and Thermic Effect of Food in Normal Weight and Overweight/Obese Children

Objectives: To determine the effect of protein content of familiar breakfast meals on subjective appetite, food intake (FI), glycemic response and Thermic Effect of Food (TEF) in normal weight (NW) and overweight (OW)/obese (OB) children.

Specific Objectives:

1a.To determine the effect of familiar breakfast meals (450 kcal containing eggs and varying in protein content (15, 30, and 45g) on subjective appetite, glycemic response and food intake at a test meal 4 h later in NW and. OW/OB children.

1b. To describe the effect of isocaloric (450 kcal) familiar breakfasts either high in protein (optimal protein from Objective 1a) or low in protein on TEF and substrate utilization over 5 h in NW and OW/OB children.

Detailed Description

Hypothesis: The investigators hypothesize that increasing the high-quality protein content of a breakfast meal will dose dependently increase subjective satiety, lower FI and glycemic response, and increase the TEF in both NW and OW/OB children.

Primary Outcome Measures

Outcome Measure
Time Frame
1a) Ad libitum food intake (in kcal)
Time Frame: Four hours after breakfast
Four hours after breakfast

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
1b) The thermic effect of a high versus low protein meal
Time Frame: Resting energy expenditure (REE) at baseline and up to five hours post test meal
REE will be determined by indirect calorimetry under a ventilated hood (ParvoMedics TrueOne 2400 automated metabolic gas analysis system, Parvo Medics, USA)
Resting energy expenditure (REE) at baseline and up to five hours post test meal
Subjective Appetite
Time Frame: Assessed every 15 min for 4 h
Assessed every 15 min for 4 h
Blood glucose response
Time Frame: Measures at 15, or 60 min intervals for 4 h
Finger prick capillary blood glucose (in mmol/L) at baseline, after breakfast (30 min), at 60 min, and in 1h intervals onward
Measures at 15, or 60 min intervals for 4 h
