I feel your pain, Kime! I had to retire on disability 6 years ago due to spinal stenosis and SI joint disfunction and knew going into my surgery that I would not be compliant with the exercise part of the equation. I also have a knee that is in need of total replacement. I've lost 91 lb and not in the way I imagined. The first year, I lost about 60 lb, second year, 10 +- lb and in year 3, so far almost 20 lb.
In the second year, I was basically maintaining, away from home for extended periods of time and enjoying a wide variety of foods, and living life. I also started developing some problems and at the end of my second year thought I was going to lose my band.
In this, the third year, I've learned some important things about band related complications and being proactive, seeking second opinions and sticking with my band friendly food plan, with modifications, even with no fill...I'm still losing.
One of the things you might consider is increasing protein calories, change your diet up for a few weeks. This is a tactic my nutritionist taught me. I don't lower overall calories, just add a protein snack mid afternoon.
Things don't always go according to plan. That doesn't mean we're not successful, it just means we're on a little side road, enjoying the scenery while others are on the interstate, zooming to their destination. Enjoy the journey
