does anyone know a simple diet to combat fat and cellulite?

hi everyone
the other day i was horrified to notice that i was getting a bit of cellulite. i exercise about twenty minutes a day on the orbitrek plus i do a lot of walking. i have a full schedule (waitress and student), so i do eat a lot of takeaway junk food plus its putting a hole in my pocket with how much i spend. so i was wondering if anyone knows a simple and cheap diet i could go on? i would be extremely grateful if anyone has any ideas. plus would anyone know any good but not over the top expensive cellulite creams? cheers!
