Food preferences and weight change during low-fat and low-carbohydrate diets.
Abstract
UNLABELLED: Understanding associations between food preferences and weight loss during
various effective diets could inform efforts to personalize dietary recommendations
and provide insight into weight loss mechanisms. We conducted a secondary analysis
of data from a clinical trial in which participants were randomized to either a 'choice'
arm, in which they were allowed to select between a low-fat diet (n = 44) or low-carbohydrate
diet (n = 61), or to a 'no choice' arm, in which they were randomly assigned to a
low-fat diet (n = 49) or low-carbohydrate diet (n = 53). All participants were provided
48 weeks of lifestyle counseling. Food preferences were measured at baseline and every
12 weeks thereafter with the Geiselman Food Preference Questionnaire. Participants
were 73% male and 51% African American, with a mean age of 55. Baseline food preferences,
including congruency of food preferences with diet, were not associated with weight
outcomes. In the low-fat diet group, no associations were found between changes in
food preferences and weight over time. In the low-carbohydrate diet group, increased
preference for low-carbohydrate diet congruent foods from baseline to 12 weeks was
associated with weight loss from 12 to 24 weeks. Additionally, weight loss from baseline
to 12 weeks was associated with increased preference for low-carbohydrate diet congruent
foods from 12 to 24 weeks. Results suggest that basing selection of low-carbohydrate
diet or low-fat diet on food preferences is unlikely to influence weight loss. Congruency
of food preferences and weight loss may influence each other early during a low-carbohydrate
diet but not low-fat diet, possibly due to different features of these diets. CLINICAL
TRIAL REGISTRY: NCT01152359.
