Sounds like your doc does fills slowly. Most people hit that green zone with about half the band filled, but everyone is different. Any loss is a good loss and 25 lbs is quite an acheivement. You seem to really have a desire to learn how to do it right. Planning really is the key. Also, I'm a fan of myfitnesspal. You can access it online and there is an app for the phone. I track just about everything I eat on that (trust me it gets addicting) and I have definitely been able to see patterns in my weight loss. For example, I tend to plateau when I go too long on too low calorie of a diet and am exercising too much. I can usually break a plateau with upping my calorie intake and lowering my cardio. It's just a good way of tracking and figuring out how your body works. You keep doing what you're doing and make yourself aware of your actions and that weight will keep disappearing!
