There are at least two separate parts to obesity recover, knowing what must be done, food wise, and second becoming willing to do it. Both are a struggle. Sorting out the real information from opinion in the food world take a bit of understanding. But the real challenge is the doing of it against all the social, environmental, marketing, and cohort pressure.
I need to be happy with my life and happy to follow a strict food plan, essentially paleo minus EVOO, butter, nuts, cheese, but I also need to include a bit of starch- potatoes, else I get too hungry. So I no not fit in any camp, but somewhere between PHD and Paleo, not Atkins, not Dukin, I tend to refer to this as 19th Century, for the lack of a better term.
But the willingness is the issue. Among my fraternity of exobese, I frequently see this as the problem. Gratitude lists, and a feeling of being pleased with the current situation both help. It is really about maintaining that attitude of being pleased that lifts the spirits.
