No such thing in our medical history as "carb deficiency". No person in history ever died of lack of carbs. Protein and fat are the building blocks of our evolution. Grains (wheat, rice, rye, barley, etc.) are the world's first "fast food". How to feed a lot of people with instant-energy food that's storable and portable and lasts a long time? Learn to process grain. Very little nutritional value but it fills the tummy and provides instant energy for instant "bursts" before crashing (good for marauding war bands

What the Dieticians, NP's, DE's, etc tell you is best for you comes from what the dairy board, grain council, heart association, etc. have put together for them. Follow big business and follow the money trail. Don't think for a minute that politics aren't involved in what you're told you should eat. Problem is, they always leave out the reason why (for a reason, I guess
Understanding Diabetes (of any kind) is understanding that there is a problem metabolizing carbs.
Unfortunately, many professionals don't get this simple, basic truth (unless they're diabetic themselves??). They have a calculation table that tells them how much you should eat based on weight, activity level and other stuff. This can be helpful to those who are maybe at the very beginning of understanding how to even eat a proper meal. Those of us who've gone a little further - logging: test results, food eaten, exercise, etc. - have learned that by actually looking at and analysing the data a bit, we see exactly where we need to make some changes. It's also shown us that the recommended ADA/CDA diet is waaay too high in carbs. Maybe they try to accommodate the overwhelming percentage of diabetics who can't give up their breads, pastas, cereals, potatoes and rice? It's a guideline and should be treated as such.
Every time I asked my (various) dieticians why we "needed" carbs - they never had a real answer. What's yours say? !-)
