Lots of us can relate to your appetite curse. I'm convinced its a psychological thing that needs mental adjustment in addition to a dietary overhaul and exercise. Fear of disability, or worse, is a powerful motivator to get one going in the right direction.
Boredom is the trap for me. I can go for hours without thinking about food as long as I stay busy. When I sit down, and the focus on something productive stops, the food and beverage monster appears.
I'm reprogramming with the commitment to stay busy at something constructive during most waking hours. Riding my bike 5 miles each way, often, to a fitness center for workouts is part of the plan. Home and gardening work, auto and bike maintenance and pursuit of outdoor sports are always available here in Florida. I'm also looking for a volunteer job at one of our outdoor recreational organizations. Retirement makes these activities possible for me. Dialing back on Internet time is another part of the plan. Shedding 30 pounds by fall is my goal.
The consequences of severe diabetes should help keep you on track. In my case, heart disease is the killer I need to be mindful of. Its a matter of mind control over the urge to eat ourselves to an early death; whats so hard about figuring out why this is important?
Good luck.
