I know that a ton of carbohydrate (or protein for that matter) can make one sleepy. But a single cup of pineapple? Or one small sweet potato? Or a cup of melon?
I had been pretty high fat/mod protein/low carb for over a year and decided to add back in one cup of either fruit or sweet potato at lunch and again at dinner. My total calories remain moderate. It doesn't seem to matter whether it's fructose or glucose. With this change, right after eating, it's like I got slipped a mickey (or two).
I'm hoping my response will lessen as I acclimate. After three days of face-down-post-prandial-couch-naps, I got ahold of myself today, slapped my face, and went for a long walk to push past the Somnolent Vortex.
Anyone else have a similar response to fruit or sweet potatoes?

Carbohydrate making one sleepy after consumption is indicative of poor insulin sensitivity.

It does for me sometimes. I've taken to eating low carb during the day, and then having some fruit after dinner. I don't know if I'll keep this up, but for now, the sleepiness coincides with bedtime, so it's no big deal.

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?

A fine reason NOT to go very low carb. It makes it difficult to tolerate carbs once you to too low for too long. Why are you VLC? Are you trying to lose weight? My recommendation is to have some carbs every day, just to keep your body from loosing the ability to handle them. I prob have 150-200g per day, but I am very active and do close to 3000 kcal per day. But most people can do at least 100g per day just fine. Its low enough to have some benefits and to be fat-adapted, but not so low that when you do have carbs, your body reacts negatively.
