REIG GARCIA-GALBIS, Manuel; RIZO BAEZA, Mercedes  and  CORTES CASTELL, E.. Predictors of weight loss and fat in the dietary management: sex, age, bmi and consulting assistance. Nutr. Hosp. [online]. 2015, vol.32, n.3, pp.1028-1035. ISSN 1699-5198.

WL%: percentage of weight loss; % FL: percentage fat loss; PNLWF: patients who lose weight or fat; PLWF: patients who lose weight and fat. Objective: assess whether the% WL and FL% in the dietary treatment was affected by gender, age, BMI and assistance to the query. Method: 4,700 consultations, 670 patients (BMI≥25), in the south-east of Spain (2006-12). Balanced and hypo-caloric diet was used. Two types of patients: PNLWF and PLWF (91.9%). Results: in PLWF, men and those attending a greater number of occasions to the consultation have shown a greater loss against women (%FL: 23.0 vs 14.3%, p = 0.000; %WL: 7.7 vs 6.6%, p = 0.020), and those who attend less frequently (%FL: 19.1 vs 7.3%, p = 0.000; %WL: 7.8 vs 2.9%, p = 0.000). Multinomial regression analysis (PNLWF / PLWF) indicates that only attend more than one and a half to the consultation is a factor in the loss, OR 8.3 (IC 95% 4.5-15.1; p = 0.000). Conclusion: the body fat measurement provides additional information lost weight; Most patients attend more than six weeks, obtained a high %FL; attendance is a predictor of loss; the %FL indicates that the dietary management plays a major role in the resolution of this pathology; It is recommended to design practical schemes of action process nutritionists according to the IMCi and variable.
