Dreaming of effective diet change? Motivation, emotions, and dietician presence can all matter

Abstract

The objective of this study is to verify the relevance of motivational and emotional factors, as well as dietician presence in relation to the optimization of the dietary pattern-change process. This study was carried out with an on-line survey, including 341 respondents, almost half of whom were consulted by a dietician. Two measures were applied to evaluate the effectiveness of the dietary pattern-change among participants. The first of these measures refers to subjective evaluations of diet improvement, while the second refers to weight loss. The results show that autonomous motivation and dietician presence are associated with positive anticipatory emotions, and diet improvements. Extrinsic regulation, dietician presence, and lack of negative emotional experiences are related to greater weight loss.
