Your average serving of porrige has about 27 grams of carbohydrate, and more or less zilch sugar. And oats are about as slow release as you get. It's not exactly a huge bowl of white pasta. The reason everyone is encouraged to eat such meals for breakfast is that they efficiently deliver energy in about an hour and that lasts for a reasonable time.
You could try leaving it out. But my personal experience is that without a small carb kick-start to my day, I'm going nowhere fast. I usually do my best to keep carbs to a reasonablely low level, but yesterday, i skipped the slice of toast and just had eggs for breakfast. The morning was very nearly a total wash. It wasn't until I had a small portion of noodles with my lunch that I actually started feeling up to facing the day. By comparison, I had some granola and a sliced banana for breakfast this morning, and despite only getting a few hours sleep, I feel great, ready for the whole day.
I suppose the only thing to point out is that no two diabetics are exactly alike. If you can function while cutting out almost all carbs, then that's great, you should definitely go for it. But I don't believe it to be an arguable point that everyone is capable of doing so. I know I sure as hell can't. I'm sure there are a lot of people here who would be shocked by the amount of carbohydrate I eat, but 'low carb' is a relative term. Low compared to what? Sure I had granola and banana for breakfast, but before I was diagnosed, I could happily finish off six deep dish pancakes and maple syrup with no problems (and NO, haha! I'm a type 1, so that's
not how I got diabetes. LOL)
You can only do what works for you, or in this case, for your husband. If blood sugar is level and easily enough controlled on a moderate, or even high carbohydrate diet, then the argument for low carb is perhaps less pressing. I, myself, would only argue a seriously low carb diet for those whose bsls peak and trough quickly and frequently. If that's not your husband, then the two of you are possibly going through a lot of misery for minimal benefit.
If you don't mind me inquiring, Ming, how old is your husband and what percentage of his total weight would 6lbs be? Whether or not you can 'work' any given diet can be affected by both your age and general bodyshape/type, as both have significant influence on your metabolism.
