Ok, first of all this guy is on the right track, but he is overlooking a few things.
First, Milk isnt the best thing for pwo shakes. All you should have in your post workout shake is whey and high gi sugars like dextrose/maltodextrin/wms. Milk has a lot of other shit in it, including fat and lactose that will have adverse effects if taken post workout. Its odd to me he would condem milk, then put ice cream in his shake, its the same shit, wtf is he thinking?
Second, I dont see a problem with drinking milk other times of the day, just not around pre or post workout shakes. Its packed with all kinds of good things, just remember it has a lot of sugar, and lactose has some kind of effect on insulin, so it could facilitate fat storage, but I have no specific evidence of that.
Thrid, I didnt know the 80's were making a comback ... oh, wait, they arent.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
