Oatmeal, as i've read, can be disastrous for most hypoglycemics, but for a few it's okay. The hai diet, in fact, mentions you should never try it at first and then only in very small amounts if you want to test it. What you said is true, it's not just the total carbohydrates, but also the amount you eat at once, i've also noticed this. That's why you find a satisfactory level and stick with it, it's so the pancreas gets used to it and then you build on that level very, very slowly, perhaps even going so far as adding only 5 extra grams per week to your diet. Also what you say is a great way to adjust. When I begin to experiment, that's the first thing I thought of doing, adding carbs not from the beginning of the day, but from the last meal possible. The reason is that your body by the end of the day has more energy stored up so any lows that would normally feel pretty bad earlier in the day are eliminated because the body quickly normalizes the sugar level with available reserves. That's why they don't effect you as much. Plus, after the body gets active, by the end of the day it's ready to eat more carbohydrates. I've noticed that it seems best to eat the majority of your protein in the early hours and then have a little more carbohydrates later in the day, say from the fourth meal on.
