No fridge means your probably going to be eating alot of tuna. Unless you can find another animal protein that doesn't require refridgeration. Since you've never ate right, all you need to do is start eating clean solid meals based on moderate portions of meat and complex carbs. Good protein sources= chicken, beef, turkey, tuna,...(animal protein). Good carb sources= oats, rice, whole grain, beans, potato,... meals every few hours, lots of water, don't cheat.
