Like many people in the United States, I spent most of my adult life on a diet. Sometimes the diets would "work" for a little (I would lose weight), but the process sucked. I was always hungry and fixated on my next meal. This lifestyle was so difficult to sustain that I was constantly on the lookout for the true answer to effortless weight maintenance.  Fortunately, in my quest for the next best diet, I found Eat Fat Get Thin and The Primal Blueprint. Thanks to Mark Hyman and Mark Sisson, I learned that fat is actually our body's preferred energy source. The Standard American Diet emphasizes utilizing glucose for energy, which often equates to empty calories that leave you hungry, with your body producing too much insulin. Too much insulin equals inflammation; too much inflammation equals disease.
