Effect of self-monitoring on weight loss and dietary adherence in overweight and obese individuals: a randomized clinical trial
Abstract
Introduction: Hypocaloric diets combined with self-monitoring may be a good strategy in the weight loss process. The aim of the study was to verify the effect of self-monitoring on weight loss and diet adherence in overweight and obese individuals. Materials and methods: The study is a randomized clinical trial with 2 groups in parallel. Eighteen individuals (3 men and 15 women) with body mass index (BMI) 28.3 ± 2.3 kg / m², age 27.3 ± 4.5 years, sedentary, were evaluated. Subjects were randomized into 2 groups: Diet (GD; n = 10) and Self-Monitored Diet (GDA; n = 8). The total energy value of the dietary planning had an energy restriction of 500 kcal from the calculated total energy expenditure. Weight, height and adherence to diet were measured at the beginning (0), intermediate consultation (week 3) and end of intervention (week 6), as well as perimeters, sleep quality and level of physical activity at the beginning and end of the study. A significance level of 5% was adopted. Discussion and results: GDA participants lost ~ 3.2% of initial weight at 3 weeks and ~ 4.5% at 6 weeks (p<0.05). There was no significant difference in weight loss in GD participants throughout the study. There was a reduction in waist and abdominal perimeters after 6 weeks of intervention in both groups (p<0.05). Conclusion: Low-calorie diet with self-monitoring through a photo app can be a useful strategy for inducing weight loss for overweight or obese individuals.
