I have my post workout carbs with whey. I have always been told Casein protein (milk) is not ideal post workout because its a slower digesting protein.
Other way around. Casein is better BECAUSE it's slower. Casein's slower nature allows it to stick around, producing a result which in this regard is superior to the transient appearance of amino acids from whey.

Incidentally, the authors of this study cite earlier research which showed three meals produced superior protein synthesis when compared with smaller meals in more frequent feedings.
"with respect to the issue of leucine balance, it is noticeable that Young???s
(13) group recently reported a 24-h leucine balance, which was better with three discrete meals than with multiple small repeated meals, the latter circumstance somewhat mimicking a slow protein absorption."

The authors go on to mention carbohydrate was included in the 1995 study, which is important to mention here because carbohydrate slows down the absorption. In other words, in a mixed meal, none of this matters. In a liquid meal of only protein, if you feel you must only have this and not a mixed solid meal, pick casein for your post-workout meal. But thinking of whey as superior for post workout because it is fast is simply fallacious.
Some people even say it slows the absorbtion of whey if taken together post workout.
Which is probably a better way to go. Note that milk contains both proteins. Babies need the anabolic quality of a slow, mixed liquid meal with various proteins, carbohydrates and fats.
I have tried both while cutting and here is my findings
Whey alone post workout- I will lose weight slighlty faster, but my muscle mass suffers. I will look a bit deflated. (compared to my bulk look)
Of course you do - you're not all carbed up. Glycogen isn't muscle - it's just IN muscle. Have a carbup, then go train the next day. Trust me, you'll re-inflate.
Whey with dex/malto- I lose weight a bit slower but I keep most of my bulking gains and don't look deflated.
My conclusion is that if your main priority is to lose weight as fast as possible without worring about losing muscle mass then whey alone post is a better option, especially for females who are not concerned about muscle.
Oh, wow. I've been thinking all wrong - I was supposed to be unconcerned with muscle loss. I mean, why would a woman want pesky MUSCLES - besides, it's super-easy for women to gain muscle, not like how it is for men. For men, muscle gain is DIFFICULT, but for women, we gain it so easily, we don't care if we lose some while dieting!
I'm SO glad you told me this. Maybe now I can get that soft, skinny-fat physique I've been after for so long!
If you are concerned about losing size while cutting simple carbs with your whey post have helped me keep good size.
Of course like most advice it's trial and error and somethings work for some and not others.
Of course - everybody is different. This is why it's utterly useless to study human physiology. There's no possible way to generalize from one person to another. It's a silly, made-up science.
