Sometimes I'll have some mixed nuts here or earlier with my banana. As you can see, this is a pretty bland diet and it doesn't have any dairy, but it gets me 20 grams of fiber without too much of a bulky, fatty, calorie count. I'm slimmer and fitter than I've ever been in my life. The key to staying on this course of action is to decide that you want to be thin. That mindset will help push you over the cravings and temptations to cheat and eat a donut or skip your PowerWalk.
Dinner is the variable.
Sometimes Janna wants to go out to eat. Sometimes we want Taco Bell or Pizza Hut or a steak or fast food. If I'm worried the meal didn't get me enough Fiber, I'll down a glass of Metamucil when I get home. If I get the munchies, I chew a piece of Trident Bubble Gum. Blowing bubbles takes my mind off my hunger.
