Repeated Sweet Breakfasts and Subsequent Sweet Food Preferences and Intakes

Impact of Repeated Sweet Breakfasts on Subsequent Sweet Food Preferences and Intakes

This study will assess the impact of repeated sweet breakfast consumption versus repeated non-sweet breakfast consumption on subsequent sweet and non-sweet food preferences and intakes

Study Overview

• Status: Completed
• Conditions: Repeated Sweet Food Consumption
• Intervention / Treatment: Behavioral: Sweet food consumption; Behavioral: Non-sweet food consumption

Detailed Description

Participants will be randomized to receive either sweet or non-sweet breakfasts for three consecutive weeks, and impacts on food preferences and intakes will be assessed at baseline (day 0), after 1 week (day 7), and after three weeks (day 21). Preferences for sweet and non-sweet foods will be assessed during two taste tests at each assessment time, where six different foods will be rated. Sweet and non-sweet food consumption will also be measured at two meals at each assessment time - breakfast and lunch. Identical buffet meals composed of sweet and non-sweet foods suitable for consumption at breakfast and lunch will be provided ad-libitum. Intervention breakfasts will only be consumed on the days between test days.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Sweet food consumption; Sweet breakfasts. Participants are asked to consume a sweet breakfast every day for three weeks (excepting on three days when outcomes will be assessed (days 0, 7 and 21, day 21 reported). All foods will be provided.	Behavioral: Sweet food consumption; Sweet food consumption at breakfast
Active Comparator: Non-sweet food consumption; Non-sweet breakfasts. Participants are asked to consume a non-sweet breakfast every day for three weeks (excepting on three days when outcomes will be assessed (days 0, 7 and 21, day 21 reported). All foods will be provided.	Behavioral: Non-sweet food consumption; Non-sweet food consumption at breakfast

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Food Preferences	Ratings of three sweet and three non-sweet foods during a taste test at breakfast. Ratings measured using 100mm VAS scales for different hedonic factors - pleasure, sweetness, desire to eat). Scores range from 0-100 where 0=least and 100=greatest for each hedonic factor. Assessments made on Day 0, 7 and 21, Day 21 reported.	3 weeks from baseline
Food Intake	Amount of sweet and non-sweet foods consumed during breakfast on test days (days 0, 7 and 21, day 21 reported)	3 weeks from baseline

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hunger Ratings	Ratings of subjective perceptions (two meals). Ratings measured using 100mm VAS scales for different subjective factors - hunger, thirst, fullness. Scores range from 0-100 where 0=least and 100=greatest for each subjective factor. Assessments made on Day 0, 7 and 21, Day 21 reported.	3 weeks from baseline
Food Preferences at Lunch	Ratings of three sweet and three non-sweet foods during a taste test at lunch. Measures are the same as those used at breakfast. Ratings measured using 100mm VAS scales for different hedonic factors - pleasure, sweetness, desire to eat). Scores range from 0-100 where 0=least and 100=greatest for each hedonic factor. Assessments made on Day 0, 7 and 21, Day 21 reported.	3 weeks from baseline
Food Intake at Lunch	Amount of sweet and non-sweet foods consumed during lunch on test days (days 0, 7 and 21, day 21 reported).	3 weeks from baseline
