I actually have a friend who several years ago went on this low carb diet also. She got as low as 92 pounds because of her obsession with losing, and ended up in the hospital.
There is a very fine line between anorexia and low carb when you get THAT LOW with weight for any adult person!!! But you feel that since you are eating, then everything should be fine, but PLEASE start eating more carbs, I am very concerned about your weight.
Someone said throw away the scale, but the thing is, a person that could possible have an eating disorder will NEVER see themselves thin, but the scale doesn't lie, and the scale will hopefully tell you to START EATING MORE CARBS!!!!
I hope no one find this post offensive, I am just concerned about this persons mind-set along with weight loss.
My goodness, I am 5'4 and have reached my goal today, and yes I am thinking I would actually like to lose another 5 pounds, but boy do I feel good about where I am right now!!!!!!!!!!!!

Good luck!!!!
