I told my doctor the week before my husband started this WOE in June. He wished us good luck and said to make sure we exercise. This was a welcomed surprise since this is more of an "old fashioned" doctor to some respects. I'm sure when I see him again he will be shocked because my hypoglycemia symptoms no longer exist and I've already lost 1/2 of my goal. Don't worry about what your doctor will think or say because you know why you are changing your eating habits.
