After work, I would go to a drive thru, chow a bit and then do a couple of bjj sessions. Gymnastic practice as well during the weekends. Simply didn't have enough time to prep food, even if I did, the extra calories really helped me. Now that fastfood is up, I'm finding myself spending more time and energy having to prep food. It's definitely cheaper but the convenience helped me get through tournaments, now my hobbies are strained because of food.
