I get it: No one wants to be told to lay off the Snickers, M&M's, ice cream, Cheetos, and assorted other junk food treats. However, there are many foods that should not cross your lips.
Here's the important concept. When you get to page 116 of the book, it states: Choosing food that tastes great and is satisfying can help us eat less, while enjoying it more.
That's the key to successful lifestyle change. I describe it here. If you can figure that out, the desire for the aforementioned junk will tend to go away.
It's a very simple concept that works. By the way, once you practice the concept, you can eat more. The eat less message is a myth.
