The diet thing is hard. After decades of frustration I lost weight in stages. By stages I mean different years. 20 pounds one year, 5 a year or 2 later, and so on. A year ago I decided to lose 5 pounds, to drop below 190–I ended up at 175. Walk more eat less. Now my discipline is enforced by what my system has trouble digesting–acid reflux. I will lose 5 more by the end of summer, of maybe fall. I gave up meat last month and I feel a lot better. No plan that costs money, just less food and more walking.
It sounds like you found the same epiphany I did. TR
