Intermitent fasting- can i have a post workout whey protein shake?

So i'm thinking about intermittent fasting. I've been told i can chose any 6-8 hour gap in the day. I would prefer eating from 3pm onwards because i'm a late night eater and am too busy through the day really to be organised about food. But i workout from 7am to 9am, which involves weight training and a spinning session usually. I always consume bcaa before and after workouts, and creatine beta alanine before then finish with two scoops of whey and water. so my question is, if i'm meant to be fasting till 3pm can i still have my post workout protein shake? or should i wait until 3pm to do so? Whey protein is a past absorbing protein therefore in my own mind i feel like my training is more effective if i consume my shake straight away, however, i do know that your body continues absorbing and requiring protein throughout the whole day and the 15 minute window is a so called myth.

Seemingly the definition of IF is that you don't eat anything. Consumption of liquid like water, tea or coffee seems to be ok. That's the way I do it. That doesn't mean you can't drink your shake. I'd suggest you try it for a few weeks with shake and without and see what the results are for you. Nobody else knows your body like you do. I'd be curious if you try it, so please report back what you find.

i dont think you can... i think intermittent fasting depends on not spiking your insulin, im pretty sure whey/protein(anything but fat) does this and in fact you eat after you workout specifically to spike insulin.. thats the point.

so the answer is no, you should workout later in the day, or not intermittent fast during this time(assuming building muscle is important to you)

keep in mind this is my perception and my perception is not guaranteed to = reality

edit: Tangent:: some people may say that since your insulin sensitivity is highest in the morning that working out, then eating right after that , the huge reaction to insulin in your body would help muscle growth even more, but i think its more like a bell curve.... im pretty sure i read something about this on dangerouslyextreme. i think the conclusion they came to was exercise in the evening and eat right after. not really sure how this helps you, but maybe you could start fasting earlier before you go to bed, maybe take a tbsp of honey right before u sleep so your blood sugar doesnt drop too low at night... but then u have to make sure its not enough to negate the fasting effect.

ie move your window of eating between 8a-4p and eat your meals after you [email protected] 7-9am(breakfast)and 3-4pm(dinner)
