yeah if your seriously malnourished and you eat like 100 calories a day maybe....but I used to have an eating disorder ate about 600 calories a day and didn't lose half as much hair as im losing now, I now have candida and eat about 1800 calories a day and am experiencing much greater hairloss than I ever did when I was malnourished. It is the toxins that the candida realises I believe that causes the hair loss.
