Examining mindfulness as a predictor of weight loss – Findings from the DIABEGG study

Objective Identifying individuals who are less likely to respond to a weight loss intervention allows better allocation or focus of resources to achieve better weight loss results. The current study investigated whether baseline levels of mindfulness would predict weight loss during a 12-month diet and exercise intervention. Methods The Five Facet Mindfulness Questionnaire (FFMQ) was administered and body weight measured, at baseline, three, six and 12 months in 140 participants with pre-diabetes or type 2 diabetes mellitus and a body mass index of ≥25 kg/m². 137 of 140 participants completed the FFMQ at baseline and were included in this study. Results There was no correlation between baseline mindfulness scores and weight loss. Mean baseline total FFMQ score was 112.2 [95% confidence interval: 109.4, 115.1] which did not change over the course of the study. Mean baseline body weight was 95.1 kg (standard deviation (19.1 kg)). There was a significant decrease in weight at month 12 (−3.8 kg (±standard deviation 5.8 kg)). This is comparable to the weight loss achieved by participants in other interventions of the same duration. Conclusions The findings suggest that baseline dispositional mindfulness does not predict the amount of weight loss in a lifestyle (diet and exercise) intervention.
