Brief Summary: INTRODUCTION: Programs involving physical exercise have been widely used to reduce weight and fat mass (FM), as they increase energy expenditure, facilitating the daily caloric deficit. Resistance training (RT) is one of the most beneficial models for fat-free mass (FFM) gains, however, it is not clear whether a short-term RT program can influence food intake and appetite, as well as whether these Adaptations are different in obese and eutrophic women. OBJECTIVE: To investigate the effects of short-term resistance training on appetite, energy intake and body composition in obese and eutrophic young men and women and verify the relationship between these variables. METHODS: This randomized clinical study was conducted with 35 women and 35 men, aged between 18 and 35 years. The training program lasted a total of six weeks, with two weeks of familiarization, three days a week, and a session duration of approximately 60 minutes/day. RESULTS: Self-reported hunger increased in both groups after the intervention (p=0.007), while fasting satiety decreased (p=0.030), however, there were no significant effects for macronutrient intake (p>0.05). A post-intervention reduction can be observed in the general sleep score (p= 0.006; ?2= 0.21), improvement in subjective sleep quality (p< 0.001; ?2= 0.357) and sleep disorders (p= 0.034 ; ?2= 0.129). There was an increase in BDNF concentrations and a reduction in triacylglycerol for men. There was no significant correlation between changes in appetite and food intake with changes in FM and FFM in both groups investigated. CONCLUSION: After 6 weeks of RT, self-reported hunger increased in obese and normal weight women, while fasting satiety decreased. However, there was no difference in total dietary and macronutrient intake between the groups, suggesting an increase in the orexigenic drive. Furthermore, both groups showed an increase in MGL, but there was no correlation between appetite, food intake and increase in FFM
