The Psychological Dimensions of Dieting: A Two-Phase Study on Body Appreciation, Nutritional Awareness and Mental...

Dieting is a widespread behavior that is associated with psychological distress, body dissatisfaction, and eating disorders. Recent research suggests that a body-positive attitude and mindful approach to eating may influence individuals' experiences with dieting; however, their combined role has been insufficiently explored.

A two-phase study was conducted among voluntary adults using online data collection. In Phase 1, a cross-sectional survey was completed by 180 participants (71.7% women), assessing dieting behavior, body appreciation, nutritional awareness, psychological distress, well-being, and eating disorders. Correlation analyses, group comparisons, and regression models were performed. In Phase 2, 90 participants entered the pilot and received a brief psychoeducational digital material promoting mindful eating and positive body image. The follow-up assessment was completed by 59, after one month of engagement.

Body appreciation and nutritional awareness were positively associated with mental well-being and inversely related to psychological distress (p < 0.001 for all) and to eating disorder screening scores (p < 0.001 and p = 0.046, respectively). More frequent dieting was associated with lower body appreciation (p < 0.001). According to the observed pattern of correlations, body appreciation may play a role in the relationship between dieting and psychological distress. In the intervention phase, greater engagement with the psychoeducational material was associated with higher reported levels of nutritional awareness (p = 0.003) and greater perceived body awareness (p = 0.026) at follow-up; however, due to the exploratory design, findings are preliminary.

The results suggest that dieting, as a behavior, may be embedded in broader psychological processes that include body-related attitudes and nutritional awareness. Taking these factors into account may have potential implications for preventive measures aimed at promoting healthier dietary habits, a more positive relationship with one's body, and mental well-being.
