Just over a year ago, I lost a lot of weight by restricting my eating to within an 8 hour period, the other 16 hours I would only drink water. Each week I was noticing weight loss. I didn't weigh myself because I didn't want to deal with the inaccurate, cheap scales I have and in my experience, knowing my weight is just demoralising. But I was going down belt notches and clothes were getting too big for me, plus I was getting more energy. After 3 months I was feeling great.
It's a shame I got too confident in my ability to lose weight and just put it all back on.
