Background

Patients participated in weekly health coaching and followed a meal plan emphasizing low carbohydrate, low fat, and normal protein to promote weight loss.The duration of participation was variable based on patient's goal.An average of 23% weight reduction occurred in surveyed population. Previously uninvestigated, weight regain at 1 year after completion of weight loss program was examined in comparison to Self Efficacy (initial metric) and the factors of Self Efficacy (secondary metric).

Methods

A chart review was conducted on 1112 patients who began the weight loss program in 2015 or 2016.Weight regain was calculated at 1 year ± 200 days from program completion.Participants were emailed a DIET-SE screener that calculates overall self-efficacy and breaks into three factors: High Caloric Food Temptations (HCF), Social and Internal Factors (SIF), and Negative Emotional Events (NEE).Questionnaire scores were recorded using Qualtrics technology. Overall SE score and HCF/SIF/NEE scores were compared to weight regain.

Results

726 participants were contacted and 173 returned the survey (24% response rate).68 were included in the study based on the inclusion and exclusion criteria.Linear regression of DIET-SE on weight regain indicates that for one unit increase in overall self-efficacy score, weight regain is expected to have an average decrease of about 0.74 units (-0.74, p-value 0.0022).Linear regression of DIET-SE subscores are all negatively correlated with weight regain: high caloric food (-1.02, p-value 0.0708), social and internal factors (-1.72, p-value 0.0067), and negative emotional events (-2.14, p-value 0.0011).

Conclusions

DIET-SE questionnaire could be used to predict weight regain predisposition. Negative emotional events played a greater role in creating lower self efficacy (strongest of the three factors to correspond with weight gain).
