Introduction: different studies have shown a strong relationship between self-monitoring and weight loss. The objective of this review was to analyze randomized clinical trials using self-monitoring as a strategy for weight loss. Methods: a search was conducted in PubMed database of randomized controlled trials using self-monitoring for weight loss in adults, published in English and Spanish, from January 1^st, 2009 to April 30^th, 2015. The sample size, age, weight loss, BMI, intervention strategy, duration, and retention rate, were recorded. Results: six studies met the selection criteria. The intervention and the follow-up ranged from 3 to 12 months. The study population ranged from 18-74 years of age and included subjects from 50-329. Weight loss ranged from 1.14 to 2.1 kg in the control group and -1.27 to -6.1 kg in the intervention group. The six studies determined a greater weight loss in the self-monitoring group with moderate to high evaluation evidence. Conclusion: greater weight loss was consistently found in the self-monitoring group. These results suggest the need to use self-monitoring as a strategy for weight loss.
