I think the most important thing I learned and am still learning, is that it is what it is!! I have Diabetes. I can control my BS, but Diabetes doesn't disappear. It took me months to admit that. To help control it, I do aerobic walking, mild strength exercises, drink lots of water,& limit carbs.
If you don't move...your scale will not move either! I can eat the right foods, drink the water, but if I don't do my aerobic walking...the scale stubbornly sticks!! I chose walking as my exercise because I will actually DO it.
