Bf and his health

Okay so my bf is very health conscious and he inspires me alot, he grows and makes his own food and he just lives going on and on about it for hours, kinda makes me feel like im a terrible human being for eating out pretty much everyday and etc. Lol but i wana try and get to be like him cause idk anyhow how would i go by doing this and do any of you know what a HealthSmart is lol... & i cant really ask him about it
