Sweet Food Preferences Primary · Week 1

Preferences for various sweet foods/fluids, assessed using a taste test, where participants sample several sweet and non-sweet foods and rate them for pleasantness on a 100mm Visual Analogue Scale, from 0 to 100mm. Higher scores signify stronger preferences

Group	Value	95% CI
Dietary Instructions: Increase Sweet Food Consumption	66	± 3
Dietary Instructions: Decrease Sweet Food Consumption	63	± 3
Dietary Instructions: Usual Diet	68	± 3

Sweet Food Choices Primary · Week 1

Selection of sweet foods/fluids at a given meal, assessed where participants can consume freely from a meal composed of sweet and non-sweet foods, and proportion of sweet foods consumed is measured as a percentage of weight consumed

Group	Value	95% CI
Dietary Instructions: Increase Sweet Food Consumption	36	± 4
Dietary Instructions: Decrease Sweet Food Consumption	25	± 4
Dietary Instructions: Usual Diet	27	± 4

Hunger and Thirst Secondary · Week 1

Ratings of subjective perceptions, assessed using 100mm VAS from 0 (lower hunger) to 100 (higher hunger) mm

Group	Value	95% CI
Dietary Instructions: Increase Sweet Food Consumption	57	± 18
Dietary Instructions: Decrease Sweet Food Consumption	65	± 20
Dietary Instructions: Usual Diet	64	± 18

Sweet Food Perceptions Secondary · Week 1

Perceptions for various sweet foods/fluids, assessed using a taste test, where participants sample several sweet and non-sweet foods and rate them for intensity on a 100mm Visual Analogue Scale from 0 to 100mm. Higher scores signify stronger perceptions

Group	Value	95% CI
Dietary Instructions: Increase Sweet Food Consumption	71	± 3
Dietary Instructions: Decrease Sweet Food Consumption	77	± 3
Dietary Instructions: Usual Diet	73	± 3

Sponsor's own description
