Or… 3) (and what i would do,) Choose a PWO shake that includes fast and slower ‘acting’ Carbs with the Protein.
FWIW, while Maltodextrin is technically ‘complex’ as it is a poly-saccharide, it is taken up by insulin in the blood as fast as or almost as fast as Dextrose - so i would personally JUST use the Maltodextrin (something totally different actually - but of the two…).
I also disagree that you SHOULD feel hypo after taking in simple carbs - anytime.
IF you were using exo insulin, then you would shoot a finite amount, and eat your carbs.
The slin would then message the cells to take up the glycogen (etc, etc) and when all the carbs had been ‘used’ there would still be insulin there - causing hypoglycaemia as the brain is starved for energy… etc.
This starts as the effects described elsewhere - and can end in death.
However when insulin is released in a healthy adult, it is done so in DIRECT relation to the glucose level of the blood from the amount of carbs eaten (and fibre, fat, protein, you know…) - so it is released in perfect conjunction with the amount you ate… no more, no less. There should not be any feeling of hypoglycaemia in a normal healthy male at all…
Carbs of any type can not send a healthy person hypo… however…
When someone has used exo-slin, they often find that after looking for the symptoms of hypoglycaemia and monitoring the bodies reactions to carbs so intently - they then notice mild hypo symptoms and the effects of carbs ingested much more acutely in the future - even when not using the hormone. It is due to the very real possibility of diabetic coma - and as such a moderately experienced insulin user (or diabetic - however they are convinced that sugars and ‘bad’ in so many cases, and as such prefer to be a little more hypo than hyper… i digress) can recognise the onset of hypogly’ia well before even the most mild of dangers.
This is where i think the answer may be - i think that he DOES feel the mild effects of hypoglycaemia. it wont kill him, and is an impossibility - but because his family are diabetics, and he has grown up with it (i assume - or at least has a close relationship to the illness and a more thorough understanding than most) and he clearly has it on his mind… i bet he has been looking for the effects of carbs - and now with this ultra-fast digesting ‘meal’ he notices the mild effect of hypoglycaemia - only in that it is the short period between the carbs being used up and the insulin level dropping.
I am NOT saying this guy doesn’t go mildly hypo - i am saying that it is natural - and just that most people never have the opportunity to eat a small and simple dose of carbs AND also have the insight to recognise the mild effects those carbs will have.
Maybe stick to the banana, honey and a shake, or add a little fibre to the existing shake OR use milk instead of water 9depending on goal.
There is the option of reducing the carb and protein level in the PWO shake - to spike a little less slin… and eat a proper meal when home - OR just admit to yourself this is the exact reason you chose the meal in the first place, to spike the anabolic hormone insulin which drives the aminos and glycogen to the places that need it. (Add creatine, leucine and AAKG+CLA)
