Great discussion today in the live interview with Gary Scheiner. I asked a question about low carb diets and T1. Gary's response surprised me, because he basically said that low carb diets are inappropriate for T1. They're more suited to T2, he said. I went back and listened again to his reasoning (13:40-19:50 mins is that portion of the discussion). His theory is that dietary protein, which low carbers rely on, is "meant for" muscle development, bone, etc. But in a low carb diet, protein is instead being used for energy, brain, nervous system, etc - i.e. the things that carbs are supposed to take care of. So Gary recommends at least 100 carbs per day, which he says simplifies your blood sugar control.
Now, this is all fine in theory, but one thing bothers me about it: carbs still make your blood sugar go up too quickly and thus make it harder to control. Yes, protein can raise blood sugar too - Gary recommended a formula whereby you divide the amount of grams of protein by 2 to get an estimated equivalent in carb effect on blood sugar. But the big problem with a moderate carb diet, which using Gary's theory is over 100 grams a day, is that it pushes your blood sugar level up and down a lot. At least that's my experience. So with a low carb diet (and I'm doing about 60 grams a day of carbs, so it's not Bernstein level low), my experience has been that it controls BGL *much better* than on a moderate carb diet. I've also lost weight, which Gary says is what a lot of T1 people want to do.
I'll have to read Gary's new book to find out more about his theory about low carb diet. He seems to be suggesting that longer term it may be better for your body to do a moderate carb diet. That may well be so (nobody really knows the long term impact of a low carb diet), but I'm not convinced that a low carb diet complicates blood sugar mgmt. In my experience, it's the exact opposite: a low carb diet has greatly simplified my approach. I no longer use a short-acting insulin, I've reduced the amount of Lantus (long-acting) I take in morn, and (most importantly) my blood sugar readings have stabilized substantially. If you look at a graph of my readings pre-low carb diet, it is all over the place - up and down like a yoyo, at least one high reading a day. Now, with a low carb diet, it's very stable and I have very few highs (one or two a month!).
So I'm curious what others think of what Gary said, esp those on a low carb diet or who have tried it to manage their T1.
