I'm sad you feel you're too fat forever. It's just not true. I was banded in Mexico in September 2009 and after a very slow start, I lost 90 pounds but gained 25 back this past year. Mexico bandsters sometimes have to travel long distances for fills/follow-ups and it's easy to backslide when support is 200 miles away. When my restriction became negligible, I slid back into fast food and weight gain. Once upon a time 25 lbs wouldn't have seemed so terrible, even acceptable. That was before 09/09. I could feel all eyes at the office noticing my slow gain. It was humiliating. I finally snapped out of it and made an appointment for a fill. Now I know what restriction is! I don't know how I ever lost 90 lbs - it wasn't because of the band. Now I KNOW tight. One bad move with a bite of food and I'm running for relief.
I realize you're fully restricted but could you be favoring easy calories, the ones that don't take any effort? At one point, Wendy's Frosties became my favorite go-to food, breakfast, lunch and dinner! Then I graduated to Frosties with Oreos. It wasn't long before the .99 Spicy Nuggets were added to my order. A little unpleasantness afterward didn't deter me but eventually the weight gain did.
I say if you haven't gained any weight, you're in great shape and have EVERY reason to be proud. Don't be so hard on yourself. We've beat ourselves up for our entire fat lives and it has to come to an end. Try those recommended changes. I bet they'll empower you to change things even more. Also, I'd change my online name to FatNeverMore. It will come true.
