Dietary satisfaction and quality of life in individuals following diet programs satisfaction of diet programs

Purpose The purpose of this study was to assess individuals’ satisfaction with their diet programs and evaluate the impact of their diet on their quality of life (QOL). Design/methodology/approach This cross-sectional study was conducted with 812 females and 334 males ( n = 1,046) aged 18–65 years, all of whom were following a diet program under the guidance of a dietitian. The questionnaire included personal information as well as items related to dietary satisfaction and QOL, measured using the SF-36 scale. Findings Of the participants, 38.4% were aged 18–24, and 32.6% were aged 25–40. The mean score for dietary satisfaction was 3.0 ± 0.9 (out of 5), while the mean scores for the mental and physical components of the QOL scale were 62.0 ± 17.8 and 74.3 ± 19.2, respectively. Factors such as age, BMI and duration of the diet were associated with dietary satisfaction, whereas age, gender, health status, diet type and BMI impacted QOL ( p < 0.05). Dietary satisfaction scores showed a weak positive correlation with QOL scores ( r = 0.125; p < 0.01). Originality/value Dietary satisfaction and QOL are influenced by demographic characteristics, health status, diet type and the duration of the diet program. Additionally, there is a correlation between dietary satisfaction and QOL. To ensure the sustainability and suitability of long-term dietary plans, it is crucial to monitor patients’ dietary satisfaction. In this context, assessing the QOL in individuals on diet programs, using a newly validated diet satisfaction scale, adds originality and value to the study.
