We have previously reported that a moderately high fat diet increases motivation for sucrose in adult rats. In this study, we tested the motivational, neurochemical, and metabolic effects of the high fat diet in male rats transitioning through puberty, during 5–8weeks of age. We observed that the high fat diet increased motivated responding for sucrose, which was independent of either metabolic changes...
Associations of pleasure and fun with junk foods have the potential to create considerable challenges for efforts to improve diets. The aim of this research was to determine whether activating health goals had the potential to exploit mixed motivations (i.e., health and pleasure) that people have related to food, and subsequently strip junk foods of the expected pleasure derived from them. In study...
Little research has been published concerning the differences between health oriented and ethically oriented vegetarians. The present study compared differences in conviction, nutrition knowledge, dietary restriction, and duration of adherence to vegetarianism between the two groups. Subjects completed an online survey and were grouped by original reason for becoming vegetarian (n=292, 58 health,...
We explored the effect of controlled and autonomous learning choices on the consumption of a high-energy snack food, and also examined whether snack consumption during a controlled choice learning activity could ‘up-regulate’ subsequent performance on a self-regulation task. Participants were randomly assigned to a controlled choice learning condition in which food was provided, a controlled choice...
Previous research has found that while self-regulation is a resource that can be depleted, enhanced motivation to do so can help people successfully self-regulate. The aim of this research was to determine whether activating health goals—either via laboratory priming techniques or via advertisements—can help people regulate food intake later in the day, when self-regulation resources are typically...
