My 38 yr. old sister is showing signs of anorexia how would you broach the subject? - when do the signs of anorexia show

My sister was over 100 pounds. Overweight and a little lost. I am very proud of her, but now everyone's lips. There has been continuous and count calories before eating anything. Is it fair or is inclined to obsession and anorexia?
