Non-alcoholic fatty liver (FL) has a high prevalence and is associated with clinical conditions such as dyslipidemia, arterial hypertension, diabetes, and coronary artery disease. To investigate the association of physical activity (PA) and nutritional factors on the presence of FL, and to analyze the association of the energy intake/energy expenditure (EI/EE) index with FL. We studied 786 nondiabetic subjects without a history of hepatic or cardiovascular disease, and alcohol consumption < 20 g/d. Diet and PA were assessed using standardized questionnaires, and visceral abdominal fat (VAF) and liver fat by tomography. The energy intake/energy expenditure (EI/EE) index effect on the presence on FL was analyzed. No macronutrient was associated with FL. After adjusting for age, gender, VAF, and total kilocalories, PA significantly reduced the risk of FL (OR: 0.86; 95% CI: 0.74-0.99; p = 0.03). In logistic regression analysis adjusted for confounding factors, the EI/EE index was associated with the presence of FL (OR: 1.69; 95% CI: 1.02-2.82; p = 0.04). These results suggest that independent of macronutrient composition, a high hypercaloric diet with physical inactivity favours the development of fatty liver.
