The effect of intake of two sources of saturated fat (SSF) in combination with exercise (Ex) on weight gain, biometric parameters and body indices, serum biochemistry stress oxidative in liver tissue, and adiposity in obese rats was studied. Twenty-four Holtzman male rats, previously induced to obesity, were randomly divided into four groups of 6 rats per group, (T1: Obesogenic diet (OD) + 3.5% cocoa butter (CB) + Sedentary (S); T2: OD + 3.5% of CB + Swimming (SW); T3: OD + 3.5% of Red Palm Oil (RPO) + S; T4: OD + 3.5% of RPO + SW) for 30 days. The results showed that there was no interaction effect between the SSF and Ex factors in any of variables studied, except for thoracic circumference (P <0.05) showing a significant decrease in the T4 group compared with the other groups. A significant increase (P <0.05) in HDL-C blood concentrations and a decrease in adiposity were observed in the groups exercised. CB presented a tendency to increase blood glucose than the RPO (0.05

Se estudió el efecto de la ingesta de dos fuentes de grasa saturada (FGS) en combinación con el ejercicio físico (EF) sobre el incremento de peso, parámetros biométricos e índices corporales, bioquímica sérica, estrés oxidativo y la adiposidad en ratas obesas. Durante 30 días, 24 ratas macho Holtzman, previamente inducidas a la obesidad, fueron asignadas bajo un DCA con arreglo factorial de 2 x 2 a cuatro tratamientos (T1: Dieta obesogénica (DO) + 3.5% de manteca de cacao (MC) + Sedentario (S); T2: DO + 3.5% de MC + Natación (N); T3: DO + 3.5% de Aceite de Palma Rojo (APR) + S; T4: DO + 3.5% de APR + N). Los resultados no mostraron un efecto sinérgico entre los factores FGS y EF en ninguna de las variables estudiadas a excepción de la circunferencia torácica (P0.05); no obstante, la MC presentó menor tendencia al incremento de glucosa en sangre que el APR (0.05
