“…Therefore, a number of strategies have been investigated in order to induce a negative energy balance and body weight loss, such as a reduction of energy intake, an increase in physical activity, behavioral approaches and pharmacological or surgical treatments [2,3]. However, individual responses to body weight loss interventions vary widely and several studies have aimed to identify psychological, behavioral and personal predictors of this variability [4,5,6]. In this context, genetic factors have been described to be associated with adiposity and body weight control, since there are diverse genes involved in the regulation of energy expenditure, appetite, thermogenesis, adipogenesis, insulin resistance and lipid metabolism [7,8,9].…”
