Multiple‐Pass 24‐hours recall significantly predicts energetic restriction associated to weight loss

One of the main problems for body weight loss in subjects with overweight and obesity is adherence to dietary plans, therefore some subjective instruments to evaluate adherence to these treatments have been developed; however the reliability of these instruments has been questioned. The objective of this work was identifying if the determination of the energy consumption measured from a multiple pass 24‐hours recall method (MP24h) represented an assessment that might relate to dietary treatment success. We analyze data of 171 patients (average ages 31 years) who attended to the Nutrition Clinic of the Universidad Iberoamericana at Mexico City which had four visits (basal and three monitoring) and BMIs indicating overweight or obesity. To understand weight change phenomena, clinical, dietetic and anthropometric variables were tested in a multivariate model to identify those who significantly predicted weight change. Successful adherence to the dietary recommendation was assessed by MP24h, considering energy recommendation vs reported intake with a difference no more than + 10%. The results showed that the patients have and average adherence of 92%, and that this adherence significantly predicted weight change (p=0.003) in the multivariate model. We recommend the use of MP24h as a quantitative instrument for measure adherence to dietary recommendations.
