Hate to say it, but when you are done you CANNOT eat like a normal person - those of us who get fat just aren't like the 'pig out and not gain an ounce' people. That's not to say you can never eat anything fun again!
I did my dieting differently - some may disagree but it worked for me. I 'dieted' 6 days a week and let myself indulge one day a week. As time went on I really didn't indulge all that much, but the option was still there if I needed it. I still do it this way, however my week is more generous in calories so my 'free day' is less excessive. Another way to do it would be to allow yourself a certain amount of fun food - maybe two free meals a week.
When you are at goal, I'd try ramping up calories slowly, maybe in a zigzag pattern. Obsessing over food may mean you are eating too little - you'd be surprised, but at least for me the obsessions went away when I was eating enough to fuel my body and I did NOT gain the weight back!
Maintaining weight is a lifelong process - the reason why so many diets fail is because it's a 'diet' not a lifestyle. You need to find a way of eating that works for you and is a lifestyle change and you'll be able to maintain that stellar loss!
(btw, I look older too when I'm thinner. I wish I was one of those that looks younger!
