I lost about 35 lbs but apparently it was too much. I was down to 105 and everyone asked if I was sick. I kept it off for a while but I was almost starving all the time so I figured that wasn't my 'ideal'. Now I'm a little overweight again (about 126-128) but I don't starve myself and I'm still 12-14 lbs less than my highest weight.
If it matters, I'm 46.
