It's not "as if" you're unable to deal with carbs, and they get stored, built up and whatnot... That's exactly what T2 is. An inability to process carbs. Practically all carbs turn to glucose once ingested. The glucose gets stored in fat cells, as it isn't getting burned off and has no place to go at that point, but when the fat cells are full, it spills over into everything else: your blood stream, organs, tears, saliva, urine... I remember being so fatigued I'd lay in bed and wish I could go for a lie down, then realise I already was, and it wasn't helping. Fatigued to the point of pain. Sometimes my legs would just give out, there was no strength in them, and I'd go to my knees with a rather mighty thud. (I was over 100 kilo's then. Man, that hurt...). So I do get where you're coming from. If you want to maintain your weight, eat regularly, so indeed, no fasting or OMAD, but eat as low carb as possible. Maybe go carnivore (nearly or totally no carb) , or keto (20 grams or less a day). You'd be able to snack in between, as long as it'd be a no or nearly zero carb snack, like pork scratchings for instance... You'd keep your weight up to par without upping your blood sugars. You don't need carbs to keep your energy up.
