How tall are you? I'm all for high calories, but I don't think even I would start out intentionally higher than about 2000 calories at 200 pounds, including exercise. From there, you can adjust. No formula can really be expected to get it just right. But at 200 pounds, I don't think 2400 calories plus exercise calories sounds right.
For me, cutting out sugar was foundational. It just makes every thing else so much easier. I can have a real dessert about once a week (not some diet thingamajig fake food), in a smallish portion size (not two bites, not a big huge bowl either). And I can have a little agave syrup in my coffee in the morning, and a square of dark chocolate a few times a week. But more than that and I start wanting more sweets and more food in general. With this, my sweet tooth has gone WAY down. I have a hard time anymore with normally sweetened desserts. Even cereal or granola is more sweet than I can enjoy. And that "little bit" of agave syrup is less than 1/2 tsp in one cup of coffee. And that tastes sweetened.
