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
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.

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.
Time frame: 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)
Time frame: 3 weeks from baseline
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.
Time frame: 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.
Time frame: 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).
Time frame: 3 weeks from baseline
