This may help explain:
"Carbohydrate restriction drops
insulin levels. Low insulin levels
activate hormone sensitive lipase.
Fatty tissue breaks down and releases
non esterified fatty acids. These are
mostly taken up by muscle cells as
fuel and automatically induce insulin
resistance in those muscles.
This is patently logical as muscle
runs well on lipids and so glucose can
be left for tissues such as brain,
which really need it. "
Its something ive just started reading on, because I myself am fairly low carb (well I try to have a bit of fruit each day!). Its basically a low carb adaption. Not the same as pathological insulin resistance.
The sudden introduction of larger amounts of carb/sugar can thus after years of VLC can produce a diabetic shock type reaction, like strong sleepiness and even heart palpitations.
So my advice to you: having been VLC for a year or more....slowly introduce the carbs. Possibly go with low GI carbs at first? Its creating an insulin spike because your body hasnt been using much insulin. Build up your blood insulin levels slowly, and it should go away, from what I understand.
I kinda hope my bowl of fruit a day, and a bit of glucose as sweetner (prolly about 60-65 grams of carb per day), helps mitigate this myself (I cant eat starch), as I dont really want to end up in a situation where my body doesnt know what the hell to do with dietary carbs, even temporarily, it seems a bit dodge.
And my own question, here, if anyone can answer it......I basically cant get many carbs in for digestive reasons, its a dilemna, cause id prefer to be around 100gram/d:
Is 50 grams, 60 grams or even 70 grams of carbs a day (some fruit, a bit of glucose+ non-starchy veges, basically as much as I can tolerate with my illness) going to be enough to keep me from getting physiological insulin resistance to a significant degree?
Any experts on insulin and low carb out there?
