Effectiveness of mindfulness based cognitive therapy on weight loss, improvement of hypertension and attentional bias to eating cues in overweight people.

Objectives: Prevalence rates of overweight and obesity are dramatically ever-increasing across the world. Therefore, this study was to evaluate the effect of mindfulness-based cognitive therapy (MBCT) on weight loss, hypertension, and attentional bias towards food cues in a group of women affected with this condition.

Methods: A total of 45 participants were selected out of women referring to the Nutrition and Diet Therapy Clinic affiliated to Shahid Beheshti University of Medical Sciences, Iran, and then randomized into three groups of 15. The first experimental group was subjected to an energy-restricted diet therapy together with MBCT during 8 sessions, the second group took the diet therapy alone, and the third group received no intervention. Body mass index (BMI), hypertension, and attentional bias towards food cues were correspondingly evaluated before, at the end, and four weeks after the completion of the interventions.

Results: The results of this study revealed that MBCT, along with diet therapy, had been significantly more effective in weight loss, decrease in BMI, lower systolic blood pressure (SBP), and attentional bias towards food cues compared with the diet therapy alone (P ≤ 0.01). MBCT had no significant impact on the decline in diastolic blood pressure (DBP) in participants in the follow-up phase.

Conclusion: This study demonstrated that MBCT along with the conventional diet therapy was more effective in weight loss, decrease in BMI, hypertension control, as well as attentional bias towards food cues than the diet therapy alone.
