    Author: Buscemi S, Verga S, Caimi G, Cerasola G.
    Journal: Clin Nutr; 2007 Dec; 26(6):806-9. PubMed ID: 17936441.
    Abstract:
    BACKGROUND & AIMS: The metabolic syndrome is associated with central accumulation of fat. Previous studies showed that some obese subjects are characterized by a sparing energy metabolism. The aim of this study was to investigate whether obese subjects with metabolic syndrome have a lower resting metabolic rate than obese subjects without metabolic syndrome. METHODS: Forty obese subjects were divided into three groups according to the presence of metabolic syndrome and type 2 diabetes; 15 non-obese healthy control subjects were also enrolled. Body composition (bio-impedance analysis) and resting metabolic rate (indirect calorimetry) were performed. RESULTS: The group with metabolic syndrome exhibited a significantly lower resting metabolic rate adjusted for fat-free mass with respect to the control group and the obese group without metabolic syndrome (respectively: 108+/-3 vs. 118+/-3, p<0.01 and 123+/-3 kJ/kg fat-free mass 24 h, p<0.01; mean+/-sem). The obese group with metabolic syndrome and type 2 diabetes (T2D) had a not different adjusted resting metabolic rate (114+/-6 kJ/kg fat-free mass 24h) with respect to other groups. CONCLUSIONS: An energy sparing condition seems to characterize non-diabetic obese subjects with metabolic syndrome.
