I am in danger of seeming to be argumentative and negative, or even worse, Please don't take me that way, as I know you are seeing things as some potential route to get yourself better controlled... I have been there and got that particular t-shirt, so please take me the way I mean it, I am just trying to point out that you are missing a big part of the way things just are!
The reason you think you need carbs, may well be because you know the body needs carbs - but you simply do not NEED to EAT carbs at all, they are not necessary in your food to live (and Eskimos would have died out millennia ago if that was true, they don't have rice paddies or wheat fields!) you just don't need them in the sense that most people think of anyway - yes, you need carbs, but for most people you can provide your own (Liver produces them in a process called gluconeogenesis, and that's one way people lose weight on a low carb diet) - that's not to say for most people going to such an extreme is either necessary or desirable.... but effectively being arbitrarily selective about which particular carbohydrate to give up on the basis of it's common name in a dictionary is not doing what you seem to want it to do. - if it's called a sugar, give it up, if it's called a starch don't! Starch IS a "sugar" it's a polysaccharide, ("sugar" ie. sucrose is a disaccharide, it's just less saccharide bits joined up!) but in everyday speak, it's not what we call "sugar," and won't be labelled that way on a bag of cornflour!
I agree that SOME sources of carbs have their own specific problems... wheat and it's gliadin and a glutenin which produce gluten is a very specific one, and lactose in milk being another, so cutting out specific carbs on that basis seems eminently sensible if they affect you, but cutting out "sugar" (effectively we all take that in common parlance to mean a few types of "sugars" with an s!) and continuing to eat every other carb on the planet is only cutting out foods on the basis of the common names they have been given, rather than their similarity to how the body "sees" and metabolises them is a flawed concept in the first place, in the same way I wrongly claim to eat "No carbohydrates" where in reality my food still contains a fair amount in various forms, just not the massively large quantities that most overtly carb foods such as as bread or potatoes do.
Sorry if I sound like I am being pedantic, I am trying to avoid it, but it may not be coming out that way - just that what you are suggesting is similar to what I am doing, you are simply cutting DOWN on sugars (certain forms of carbs) in the same way as I am cutting DOWN on all forms of Carbs, just that you being selective on arbitrary forms of carb is just that, and you will still be packing in a considerable amount of the very things which you are seeking to avoid perhaps in the end eating even MORE!
One of the problems we all have would seem to be the fact that there is loads of misleading information out there, and lack of research too... why for example is Fructose (in fruit) seen as a simple carbohydrate that unlike some other "sugars" actually "burns" slowly?... when I (and it looks like another poster in this thread too!) see it as one of the BIGGEST problem sugars/carbs!.. Fruit, which I LOVE, unfortunately has a bigger glycaemic effect in my body than even the dreaded wheat... and I can find no real known explanation, as on the face of it, I should find less problem with it!
By removing "sugars" from your diet, you are actually stating that you will REPLACE (switch) to other forms of carbs, and effectively that is like drinking Methanol instead of Ethanol. (OK it's a bit of an over statement, just couldn't think of a better analogy at the time!)
Even among those that have no problem at all with glucose metabolism, reducing overall carbohydrate intake seems to me to be a good idea, just that replacing the form of carb you eat with another seems arbitrary and whilst a good scientific study would be interesting, I don't' think you are going to do what you actually are aiming to do, and - even if it does make a difference to you, you won't actually know which of the sugars/carbs you are giving up is making the significant difference!
For those of use with "defective" glucose metabolism, (I am pre-diabetic and suffer Reactive Hypoglycaemia) a lot of hard work on eating low carb has all been done by others, there is a mountain of information out there to plough through... I found eating low carb a life-saver, but I do accept it hasn't been the answer for everyone too... nothing is that straightforward
Good luck anyway.
