Wonderful success story. Have you read about the Minnesota Starvation experiment in which young men in WWII era were calorically underfed for 6 months? Upon refeeding they gained lots of weight, and had an insatiable appetite and hunger that took many months to resolve and caused otherwise normal young men to overshoot their original pre-weight loss bodyweights. Maybe your lifetime battle with weight also led to a similar state in which you had to eat alot initially to heal some metabolic deficit incurred through the stress of over-exercising and calorie counting. I made the connection mentally because your story and theirs were similar.
