Okay I had an eating disorder before. I since threw out the scales and do not want to own any again or weigh myself at all. I know my weight in November 2015 from a hospital appointment and I'm only maybe one clothes size up from that at most. Can I just eat the lowest amount the bmi calculator says for that last weight? And I do measure myself, but how else would I know when to reduce because I have a lot of weight to lose.
