The addition of 500 kcal·d −1 from whole foods/snacks in combination with a rigorous resistance training program promotes a weight gain of ~0.22 kg·wk −1, primarily as lean body mass, over 10 weeks in both male and female athletes.
Athletes looking to gain weight should consider increasing their caloric intake by 500 kcal·d −1 along with a structured resistance training program.

These results suggest that the addition of 500 kcal·d −1 from whole foods/snacks in combination with a rigorous RT program promotes a similar weight gain of ~0.22 kg·wk −1, primarily as LBM, over 10 wk in both male and female athletes.
