Yes and no. The only reason I say no is because if you get bloodtested they tell you to fast prior to that and you are still puncturing a needle into your arm...thanks for the support!monday should be interesting.....do u think the fact that i had not eatin anythign played a factor, since i do IF style diet ?
But for the yes side... at that point into your fast your are injecting a substance into yourself (not pulling something out like in donating blood) and your body is already on the sensitive side of things (insulin included) anyway so suddenly introducing something into your system when there really isn't much circulating to begin with is quite possibly a huge shock for it.
Just my .02.
