Umm it is easier to digest. What do you want me to tell you?
Any credible evidence anywhere that "easier to digest" makes a damn bit of difference to muscle gain? There MAY be some timing elements around protein consumption and weight gain, but they'd be of the "within a few hours" variety, not minutes. The only time you need something to hit your blood ASAP is if it's carbs and you are looking for an energy boost. With protein you just need a supply of the stuff in your blood roughly around the time you're going to be repairing the micro muscle damage from weightlifting--which will happen over many hours after your workout.
And again, just "digesting" the stuff isn't good enough. If you didn't take in the right balance of vitamins or minerals then you're just going to pee it all out, because your body isn't going to have all the factors to take maximum advantage of the protein. Guess what? Milk is a pretty good source of all those factors and in about the right proportion. Your whey protein is missing that, and you need additional supplements to get the vitamins and minerals necessary to process the protein.
But you get what you pay for, pure whey protein is literally zero fat, zero carbs and zero lactose.
Right because hey, if you were building muscle, you wouldn't need to take in any fat or carbs??? What are you on a pure protein diet? You need some fat and carbs. If you don't get it mixed in with your protein you're going to have to go get it somewhere else, and around the same time too. Hey--you could mix some in with your whey protein to save a little time. Umm... or just drink milk?
Skim milk by the way has no fat. That is why it's called skim milk. That said honestly you're probably better off with 1% or 2% milk because you know what? You do actually need some fat in your diet.
The only think I will give you is that if you are lactose intolerant then obviously you're looking for alternatives to milk, but if you aren't lactose intolerant, why complicate your life like that?
It's the highest quality protein and will give you the most protein per serving with the least amount of calories.
What's your obsession with "least amount of calories", even if you are cutting, you need to take in some calories. Skim milk is a source of high quality calories, with a LOT of nutrition per calorie. If you're on a reduced calorie diet then it's an excellent food because it covers so many nutritional bases. However, I find it hard to believe that you would be bulking up and on a reduced calorie diet... a little counter productive.
The calories in that glass of milk aren't going to be a problem.
I can drink 35 grams of protein with less than 200ml of water added easily. Good luck drinking over 3 and a half glasses of milk getting the same amount of protein.
LOL, what's your obsession with water? You don't take liquids when you are working out? You know that you are going to dehydrate yourself and fall over? If you're really that arsed about reducing water content... you could evaporate the milk a bit. Maybe even just eat milk powder, but honestly the ordinarily liquid form is better for you--and you do need to hydrate yourself, might as well take that hydration with the protein, as umm... milk?
Im not sure why you're arguing with me because obviously protein powders are superior than milk for someone building muscle.
That's certainly what the people who sell workout supplements want you to believe.
