Using a lactose-free whey protein isolate on IF?

[Tomasz_Gawel]

Hi KetoTeam!

Writing during my 4-day fast, but planning ahead for my 18:6 IF journey

I haven’t found any topic on the use of whey protein isolate.
The obvious issue to me is that we want to avoid excessive amounts of protein, and in my case I would use a lactose-free whey protein isolate that contains 22 g of protein in a serving.
I read somewhere that whey protein should be avoided at all costs, as it spikes insulin. (I guess it was ketogenic-diet-resource.com)

Nevertheless I thought that some of the you folkes that exercise maybe have some experiences and would like to share My initial thought was that maybe I could mix it with macademia nuts, MCT oil and sour cream (taste doesn’t really matter Will see how it goes after my fast

Did anyone make an attempt to fix their protein intake with whey protein powders? Any products/recipes?

I was going to use whey protein isolate in a recipe, until today, when I found a few posts on it. Here is one of the posts I found:

So I did an interesting protein experiment with Egg Whites vs Whey

I did this experiment after doing 2 5 day fasts, by doing some exercise to fully deplete muscle glycogen and then eating a set amount of protein and tracking my glucose. I added a little short chained fatty acids (butter) just to make sure I was making abundant ketones even if my insulin peaked and my glucose dropped so my glucose production wouldn’t be confounded by my brain increasing demand for the stuff… The first leg of the experiment I ate 200g of egg whites and 20g of butter and tracked…

I use whey protein without any problems but use much less than is meant to be used (about a third of a serving). Recently I’m experimenting with hemp hearts in my fat shakes instead of whey, but the taste isn’t great so I’ll either go back to whey or maybe on to egg white powder.
