The bfmnu method as an alternative to the methods in use based on energy: study of the correlation between food energy and body mass

Greta Rondini, Beatrice Olearo, Jose M. Soriano, Pietro Marco Boselli

Introduction: to establish slimming guidelines and any other changing treatments is useful to know the individual’s energy expenditure due to the fact that, nowadays, the incidence of many diseases related to the loss of lean mass and the accumulation of adipose tissue has increased. The dietary treatments are carried out on calculating the energy contained in food, and then put in relation to the total energy expended by the body in order to produce changes in body mass.Objective: the aim of this study was to evaluate the correlation between the food energy and body mass of different subjects in various pathophysiological conditions.Methods:one hundred and twenty subjects (male and female, aged 7-78 years old) were studied in various pathophysiological conditions and previously treated with the BFMNU (Biologia e Fisiologia Modellistica della Nutrizione Umana)method.Results: a correlation coefficient R2 of 0.1256 was found between food energy of the diet usually followed by the subjects and their body mass. The correlation between food energy and food mass was with R2 of 0.211. The correlation between Δ% of food energy and Δ% of body mass of the subjects, obtained through dietary treatment with the BFMNU method, was 95.77 percent.Conclusions: the correlation between food energy and body mass is not significant, being a critical point about the diets designed on an energy basis. However, the body mass of an individual is determined by mass balance, regulated by corresponding metabolic rate, calculated by the BFMNU method, thanks to which the macronutrients in the diet are absorbed, redistributed and eliminated. A significant correlation, although not straight, is demonstrated between Δ% of food energy, supplied after processing through the dietary BFMNU method, and the Δ% of body mass, obtained following the dietetic path.
