I need a simple weightloss diet with basic foods. Help!?

I need a simple weightloss diet with basic foods. Help!? I have gained 20 lbs. due to my thyroid. I am now on meds but the weight isn't dropping. I've increased my activity level, but the diet is still bad. I only like simple foods like meat, I live in a rural community now with one grocery store. . . I can 't even find chicken there safe enough to eat! What can I do with such limited food choices??? Health food is very scarce in the entire county here. . . I hate it!
