I used to be fairly muscular, though I was carrying extra body fat I didn't want. I began Reta in the spring and lost roughly 50 pounds (my estimate: 20 of muscle, 30 of fat). Over the past month, even with autumn temps that aren't that harsh, I've needed extra layers. Once the real cold hits, I'll be bundled up like a penguin given how many clothes I'll have to put on.
