I don't want to get back to my HS weight - I wasn't very muscular. But this morning, I weighed what I weighed when I climbed in Yosemite at 21. Finally made it to my goal weight. I now have a little more weight in the legs, less in the upper body, but about the same general appearance. I'm 70 and squat more now than I did then. Being able to recruit the muscles you already have is a good thing. I didn't do anything weird to lose weight. I just ate a little less and rode a little more, so that I had a straight line graph of weight loss - with lots of wiggles of course, but the general trend was a straight line. I manipulated my diet and riding time to keep it that way.
It doesn't matter how fast you lose it. A pound a month can be just fine. That would be 48 lbs. in 4 years, which is nothing to sneer at. That's about the rate I used over 2 years. I'm going to keep on losing for a while. I could have been leaner back then, too.
