I went from 170lbs to 114lbs in about 2.5 months. I was malnourished (literally starving). I ended up with non-alcoholic fatty liver disease and a host of other issues associated with starvation (including but not limited to hair loss from my head, growing new hair on my face, irregular/absent menstruation). 0/10 do not recommend. And after I lost all that weight, I still didn't feel good about myself. I wanted to lose more because I was tying my self-worth to the ability to restrict my food, exercise until I was exhausted, and lose weight. The best thing I did was get in with a good therapist. I still have body issues and occasionally fall into bad habits, but I feel remarkably better than I used to.
