About this study

Participants will be randomized to receive instructions to either increase or decrease sweet food consumption for 6 days, and impacts on food preferences and intakes will be assessed at baseline and after 1 week. 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.

Treatment and study plan

Sweet food consumption

Behavioral

Comparison of the impacts of sweet and non-sweet food consumption

Primary outcomes

  1. Food Preferences

    Time frame: Change from Baseline to 1 week

    Ratings of three sweet and three non-sweet foods during a taste test (two tests). Measures are made on a visual analogue scale from 0 (not at all) to 100 (extremely), where higher scores denote higher preferences.

  2. Food Intake

    Time frame: Change from Baseline to 1 week

    Amount of sweet and non-sweet foods consumed during breakfast and lunch. Measures are made of grams of each sweet food consumed.

Secondary outcomes

  1. Hunger Ratings

    Time frame: Change from Baseline to 1 week

    Ratings of subjective perceptions (two meals). Measures are made on a visual analogue scale from 0 (not at all) to 100 (extremely), where higher scores denote higher hunger.
