All this past winter and spring, I was the same. Just sat around, on the computer, in my easy chair in front of the TV. 16 lbs went on fast. Then the doctors found the medical reason why, directly related to my diabetes and also insulin.
Then once they discovered the connections, I went on the Atkins low carb diet, got off the insulin and started using a "Fasting" program, I have a whole new and high level of energy and moltivation and my blood testing numbers are getting much better. I am sure that counting and restricting carbs is not for everyone, but for me it is working. Blood sugar down from high 200's to 133 average right now and 10 lbs of the gained weight gone as of this morning.
But my message is that my energy is significantly higher. I am committed to stay on this program. In some rare cases, diabetes has been reversed. That is my dream.
