Congratulations on losing the weight
Mer. Everyone's experience of dieting and maintenance is slightly different, as we all are. This is my own experience and may not be true for anyone else.
I find that, after a long period of restricting my calories, my body starts fighting back and insisting on eating a whole lot more. I am tired and hungry all the time. If I increase my daily cals 3 times a week by about 300 the binging generally stops.
I also found that certain triggers (diet cola was the worst) also contributed to the binge eating. There is a theory that artificial sweeteners in particular set the brain/body up. The brain expects a lot of calories with the sweet taste and doesn't get them. So the food cravings start. Most of my binging stopped after I cut out the diet cola and the sweetener in my tea and coffee.
I never did reach my initial goal weight of 125 - too low. My body constantly fought back, demanding more food. I have adjusted my goal weight several times so that I can make peace with what my body wants to weigh. Living in a country with a cold fall/spring/winter I have a "winter" weight and a "summer" weight. They differ by about 5-7 lbs. I have accepted that and buy my wardrobe accordingly.
There is also a psychological side to losing a lot of weight. As we feel better and healthier and our clothes fit and we look good sometimes we also expect a bunch of other changes in our lives to automatically happen. Sometimes it takes quite a while for our brain/emotions to catch up to our "new" body. There are other people on this forum who can address this a lot better as they have lost really large amounts of weight and have had a a much greater adjustment to make.
