•Self-reported hunger increased at fasted and fed states and decreased self-reported fullness at fasted state in both women with and without obesity.•Dietary intake did not change throughout after 6 weeks of resistance training in both groups.•Food frequency of groups of soup and past, vegetables and eggs, and leafy and vegetables decreased pre-to-post in both groups.•There was no correlation between appetite and energy intake with body composition in both groups investigated, neither alteration in desire to eat and motivation to eat palatable foods.
The aim of this study was to investigate the effect of 6-weeks resistance training (RT) on appetite, energy intake and body composition in young women with and without obesity, and to examine the relationship between these variables. Thirty-five young women were divided according to the amount of body fat [with obesity (n = 16) and without obesity (n = 19)]. Appetite was assessed through self-reported hunger, fullness, desire to eat, satiety quotient, food frequency diary and motivations to eat palatable food (power of food scale) in both fasted and fed states (after a standardized breakfast). Energy intake and body composition were evaluated at pre- and post-6 weeks of RT. Results showed that self-reported hunger increased significantly in both fasted and fed states (p = 0.007 and p = 0.029, respectively), while self-reported fullness decreased at the fasted state (p = 0.030) in both groups. There were no significant effects for desire to eat fatty, sweet, savory and salty foods, motivation to eat palatable foods, or for total energy intake. Food frequency analysis indicated a decrease in consumption of soup and past (p = 0.045), vegetables and eggs (p = 0.034), and leafy vegetables (p = 0.022) in both groups. Fat-free mass increased significantly in both groups (p = 0.011 and p = 0.003), while fat mass did not show significant changes. There were no correlations between changes in appetite/energy intake and changes in body composition. In conclusion, following the 6-week RT program, both women with and without obesity exhibited increased self-reported hunger alongside decreased fullness, suggesting an increase in orexigenic drive. However, neither group showed an increase in energy intake and fat mass, while both groups experienced an increase in fat-free mass.
