I agree with everything you have said. In my lifetime I have lost hundreds of pounds. And yes, I did feel great at 120 and I wish I could have stayed at that weight. But between a sit-down for 10 hours a day job and a move from the city (walking everywhere) to the ‘burbs (driving everywhere) and a new husband who cooks, I gained back 125 pounds over 20 years. Now I am at an age where my doctor says I must lose weight, but cannot. I eat almost nothing because I have diverticulosis and I’m on a liquid diet. I still do not lose weight despite at least 30 minutes a day on my bike. My sister and brothers and my Dad are/were all as heavy as I am. It’s so discouraging and my self esteem has become as much of a daily meditation as weight.
