Background: Obesity and MetS has been shown to negatively impact protein synthesis rates. Objective: Determine the effects of sex and high fat/high sugar diets on mTOR signaling pathways. Methods: 15 male and 15 female wild type C57BL/6 mice were randomized into 3 groups: High Fat (45% fat), High Sugar (60% carb) and Control. While continuing diets, body weight and body composition were monitored. Following sacrifice, muscles were examined for changes in the mTOR signaling pathway. Results: Mice consuming the HF diet had the highest levels of weight gain. Females expressed higher levels of expression of P-AMPK. Levels of REDD1 were significantly higher in females than males with no effect of diet. Conclusion: There was a sex difference in body weight and muscle mass. Sex had an effect on 4EBP1 but not S6 levels.
