Being slim doesn't necessarily mean never setting foot in a restaurant again or writing off burgers for the rest of time. People who stay trim simply pick and choose their indulgences. They check out restaurant menus before going out to eat, in order to make the best diet decisions. And they'd rather have a juicy, high-quality pub burger on a whole-wheat pretzel bun than an overly processed industrial fast food hamburger patty slapped onto pure white carbs.
