Sometimes doctors aren't actually the best people to see about recommending diets. They often have outmoded ideas, and lets face it, they have to be a master of all trades, so to speak.
I'm sorry if you feel that we're getting at you, but it's the fact that you reported feeling weak, and not able to hear conversations that worries me. I am not a doctor, or medically trained at all, but that does not seem right to me, and I'm worried about you
It's the long term consequences of what you are doing that concern me. In conventional diet plans you start on a higher calorie count, then decrease it as you lose weight. That's what all the major plans do, and what I have done.
That piece of chicken that boosts you to 1 000 calories provides protein and essential minerals that you could be missing out on.
Calories from the food we eat to give us energy is only one side of the story. Food provides our body with nutrients. I understand your on a vitamin regime so possibly not missing out on that score, but it still worries me.
I think we all need to be asking for the credentials of anyone, medical or otherwise, who recommends a dietary regime. I'm the world's most difficult patient, as I won't let my primary care doctor do anything other than prescribe my regular meds without referring me to a specialist, for whatever it is that ails me.
