Jim Katsoulis argues that fiber is the most lacking nutrient in American diets and that increasing it dramatically reduces hunger. Adding more fiber creates a deep sense of fullness, making weight loss easier without constant willpower.

The nutrient that makes you thin. Imagine there was a way to dramatically reduce your hunger. How much easier would it be for you to lose weight and live as a thin person? Well, there is, and it's one of the most lacking nutrients in the American diet. It's fiber. And once you add more fiber into your body, what you're going to experience is a deep, deep sense of fullness that you may never have known before. And it makes it so much easier to naturally eat better and to lose weight almost on autopilot.
