If you do eat fast food (and sometimes on the road it seems unavoidable) try to do so infrequently and stick to the value menu. Of course, McDonald’s has a famous value menu, but so do Taco Bell (their Fiesta Potato Grilled Breakfast Burrito with potato, egg, and cheese and a price of only $1 is my favorite fast food breakfast), Denny’s, Wendy’s and Del Taco. Also, it’s admittedly difficult to resist a $5 large pizza from Little Caesar’s.
