I would, as politely as can be done, suggest that you stop talking out of your ass about things you obviously know precious little about, apart from the "facts" (dipped in corn syrup and chocolate and rolled in sprinkles) you've been spoon fed by the AHA and their ilk.
Yes, malnutrition is bad for you. What on earth does that have to do with carbohydrates? I just had a huge salad of Chinese cabbage, broccoli, celery and 4 boiled eggs. I've also finished off at least 100g of paranuts today. Does it sound like my body isn't getting enough nutrients..?
Another thing you seem oblivious to is the fact that most vitamins are found in fatty meat. We have essential fatty acids, essential amino acids, but no need what so ever of dietary carbohydrates. That's right. What? You thought you got fat-soluble vitamins from low-/no-fat veggies and bread?
If you cared to actually educate yourself on the subject at hand, you'd know that we evolved to eat meat. In fact, we probably evolved because we had such a high density energy source available, and to get it we needed intelligence and cooperation. We ate a diet consisting almost entirely of meat and fat supplemented by nuts and berries (and the occasional apple now and then) for millions of years and we were fine. Archaeological findings tell us that primitive man was bigger and built more solidly than us. Hell, they didn't even have tooth cavities, because they hardly ate any carbs.
Then comes agriculture, and the industrial revolution. In the decades prior to ~1970 about 11-13% of the American population was obese. Then, Ansel Keys and his fat-phobic peers got their way (and private funding) and in the next 10-20 years the percentage of obese Americans skyrocketed. Same with diabetes, ADHD/ADD, and a host of other so-called "life style" diseases.
Sure, historical evidence and correlation is not the same as a double-blind trial but at some point the numbers in favor of one side of the debacle become so overwhelmingly out of proportion, you just can't ignore the facts anymore. Oh, and for 40 years now AHA, ADA, ACA, etc. have put countless millions (if not billions) of dollars into proving their "saturated fats==high cholesterol==heart disease"-theory, without one single reliable study confirming any relationship between cholesterol and heart disease.
Enough about that, you're not going to listen to reason anyways. Regarding your advice to see my dietician.. Well, I have Diabetes Type 1 (the insulin dependent, "WTF happened?"-type) and yet I am adviced to eat precious little protein compared to how active I am, next to no fat and at least 60% of my daily energy intake from carbohydrates.
Do you know what happens if a Type 1 diabetic tries to eat that much carbohydrates every day? I die. Horribly. First I lose my eyesight, then neuropathy sets in with burning pains so intense it's better to have the extremeties amputated (which is what is done). Then the kidneys fail, and I am left a broken husk of a man. This is near inevitable even with blood glucose measurements several times a day, regular (according to the State) well composed meals, etc.
You know what happens when a Type 1 diabetic eats low carb? Kidneys work flawlessly, blood glucose is completely stable 24 hours a day, concentration and energy levels are higher and more stable than for years. What's even better, I'm taking one shot of 12-hour insulin each morning, down from 12-hour insulin morning and night and quick acting insulin at every damn meal.
