As a major tissue of the body, skeletal muscle buffers endogenous free aminoacids supply, acid basic capacity, energy‐yilding substrates and total daily energy expenditure. Its biodynamic properties allow daily‐free living activities for body equilibrium, locomotion and strength. In general skeletal muscle mass weight reflects behavioral factors such as physical activity and dietary intake. The aim was to determine the major behavioral (dietary and fitness) and intrinsic (body fat and plasma biochemistry composition) variables associated with higher muscle mass in free‐living adults enrolled in a lifestyle modification program (LSMP). The cross‐sectional study involved retrospective data from 660 subjects (males and females) enrolled in the LSMP “Move for Health” from 2004 to 2014. The BIA analysis of muscle mass along with height (m) was used for the muscle mass index (MMI) calculation (kgMM/m 2 ) whose quartiles were used for comparisons. ANOVA‐one way test was used to compare the quartiles of MMI and co‐variables. The data were presented as mean ± SE and p<0.05 was used for significance. The quartiles of MMI varied from 6.66±0.04 kgMM/m 2 (P 25 ) to 10.6±0.04 kgMM/m 2 (P 75 ). The top quartile was discriminated from others by higher age, BMI and WC (and abdominal sagital diameter – ASD) along with higher handgrip strength (33.6±0.84 Kj) with similar aerobic capacity (33.2±0.66 mlO 2 /kg/min) and flexibility (20.7±0.77 cm). Biochemically they were differentiated by higher triglyceridemia (157±4.76 mg/dL), γGT activity (38.3±1.85 U/L), uric acid (5.8±0.10 mg/dL) and lower HDL‐chol (44.0±0.84 mg/dL) values. Biochemical abnormalities denote pro‐inflammatory state probably led by the relatively higher fatness shown by these subjects. Nutritionally the top quartile presented higher energy intake (1840±45 kcal/d) with higher saturated fat (8.14±0.33%) participation. Their daily servings were higher for meat (1.86±0.10), oils (2.49±0.14), fibers (19.5±0.67 g//d), grains (4.07±0.14), fruits (3.40±0.22) and legumes (1.73±0.11) overall, still remaining in a poor quality diet by the Healthy Eating Index. Thus higher muscle mass in a community adults can be achieved through lifestyle modification program including dietary‐adequacy counselling preferentially associated with a resistance physical exercise training.
