Nutritional recovery with rice bran did not modify energy balance and leptin and insulin levels.

OBJECTIVE To investigate the effect of nutritional recovery with rice bran on energy balance, leptin and insulin levels. METHODS Weaned Wistar rats were fed on a 17% (Control - C) or 0.5% (Aproteic - A) protein diet for 12d. After this, rats were kept on a C diet (C) or recovered with control (Recovered Control - RC) or control plus recovered rice bran diet (Recovered Rice Bran - RRB). RESULTS Despite the increased food intake, group A exhibited lower carcass fat associated to low serum leptin. RRB and RC groups showed lower carcass weight and energy intake and expenditure. Energy expenditure was positively associated with food intake and carcass weight. Negative correlations between HOMA-IR and energy expenditure and energy intake were observed. CONCLUSION Nutritional recovery with rice bran did not modify energy balance, leptin and insulin levels.
