Hello Wade,
Sorry to read about your challenge. I hope you will win your battle.
If I may just suggest a few things.
First: Do you adhere to a schedule, exercise is very important. Perhaps an early morning and an afternoon walk. Start slow, what you can do, then slowly increase by 5 minute intervals. Even just up to the corner and back is helpful.
Second: Lay off the Bread, Pasta, Potatoes, etc. Eat more salads with low cal dressings. No add ons in the salad either !
Third: Avoid fried foods whenever possible. Bake or Broil Chicken/Fish , tasty and better for you.
Forth: Lay off the Chips, Dips, Crackers, and Sodas. Drink water, squeeze fresh Lemon in your water to add taste.
Snack on carrot sticks or celery or an apple or an orange.
Fifth: No more Sugar ! There is enough in our daily intake .
Sixth: Take care of yourself and that Diabetes. Follow all of your Doctors orders .
Most folks seek help, and expect the usual good wishes, best of luck. I wanted to offer some real heart felt advice, not just a best wishes. I understand better than many, I've always been a size L/XL myself. I try to follow my own advice, when my bad knees will allow. I like the great food as well, but restrict myself as much as possible.
Keep Fighting !
