Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be randomized to receive instructions to either increase, decrease or make no change to 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 a taste test at each assessment time, where six different foods will be rated. Sweet and non-sweet food consumption will also be measured at a subsequent breakfast at the assessment time. Buffet meals composed of sweet and non-sweet foods suitable for consumption at breakfast will be provided ad-libitum.

A subset of participants (selected at random) (10 participants randomized to increase sweet food consumption and 10 participants randomized to decrease sweet food consumption) will also be assessed via MRI and fMRI scanning to investigate brain structure and functional connectivity.
