I feel it. Living in an industrial society you really need to go against the grain to do it. As someone who has experienced substance dependency, it really is the same lizard brain urges. Avoiding hyperpalatable foods really helps. I cannot over eat oatmeal and yogurt, but bacon and hash browns absolutely. Carb portion control is really important for me, because I was eating easily over 400 calories of starches in a meal not counting anything else.
