What better for you mixing with water or skim milk... I have been using skim milk but im trying to lean out so would mixing with water be better.. it just tastes sooo much better with milk

Gaahhhh... Milk is good PWO!!! Don't listen to the myths!!
To re-post some other posts I have made:
Quote:
Actually milk is great PWO and it is due to not only an ability to rapidly increase insulin secretion, but also because of the unique combination of protein fractions (both caesin and whey).
And yes, milk will actually increase insulin substantially - you have to remember that insulin release and glycaemic index are not always related.
So, although it has a low GI (that is, it has a slow release of GLUCOSE into the blood - mainly because once the lactose is digested in the intestines, half of the carbohydrate content is galactose, and this needs to be processed to glucose in the liver before it is released into the blood) it actually has a very high Insulin index (II).
Milk has a high II because of the unique combination of amino acids (especially the high content of BCAAs) and glucose/carbohydrates. For some reason (most of which is unknown) these things act synergistically. This is also one of the reasons why whey protein also causes an increase in insulin levels - because of the high content of BCAAs.
But if you think about it logically, having milk reacti like this is, in terms of evolution, a very sensible thing to do.
As an infant/baby, you want to grow - and what better to grow than a good dose of insulin combined with an adequate mix of carbohydrates and protein!
So you have an 'instant' hit of energy and nutrient uptake (caused by the glucose component of the lactose when combined with the whey fraction of the milk protein which then act to cause a marked increase in insulin)... But then you do not want your meal to 'dissapear' from the blood too quickly (you want to provide a continuous stimulus for growth) therefore you add in a slower fraction of glucose (galactose) and a slower, anti-catabolic protein fraction (casein).
Milk does not slow the digestion of whey by any great length and the time frame is hardly relavant to anyone who has ensured that they have had a good pre-workout meal.
The milk contains different suspensions of protein. Casein is one. Whey is another. Just because the casein settles in the stomach doesn't mean the whey does as well - infact the vast majority of the whey fraction continues in the liquid fraction of the meal into the small intestine where it is absorbed without any delay.
If you REALLY did not want to delay the absorption of the whey then you would have to take it on an completely empty stomach/intestines - which means you would have to not eat for about 8 to 12 hrs....
There have also been HEAPS of threads on the topic... Do a search!... But here are a few of them:

Now.... I have been saying that milk is great for PWO for YEARS now... But if you do not believe me... Try to take a look at some of the latest research coming out about optimal PWO nutrition (S. Phillips, Tipton... etc etc)!!
International whey conference This presentation by Dr Phillips states "Bottom Line
SYNTHESIS: WHY = MIX > CAS
BREAKDOWN: CAS = MIX > WHY
OXIDATION: WHY > MIX > CAS
BALANCE: MIX > WHY = CAS
A MIXTURE OF WHEY AND CASEIN MAY PROVIDE AN OPTIMAL BLEND OF PROTEINS TO SUPPORT PROTEIN ACCRETION IN MUSCLE AS A RESULT OF RESISTANCE EXERCISE"
From This t-nation article There is this info "???Research is underway to determine which mix of whey-casein: 100% whey, 75/25, 50/50, 25/75 or 100% casein best improves protein retention after 80% 1RM whole-body resistance exercise. So far (4 subjects), the casein seems to provide a bit higher BCAA and leucine-specific responses in the blood at the 60-minute mark. Watch for protein powder manufacturers to jump all over this research as they design their products next year...."
There is also this article which just states that whey and casein both can help: Quote:
Ingestion of casein and whey proteins result in muscle anabolism after resistance exercise.
Med Sci Sports Exerc. 2004 Dec;36(12):2073-81.

PURPOSE: Determination of the anabolic response to exercise and nutrition is important for individuals who may benefit from increased muscle mass. Intake of free amino acids after resistance exercise stimulates net muscle protein synthesis. The response of muscle protein balance to intact protein ingestion after exercise has not been studied. This study was designed to examine the acute response of muscle protein balance to ingestion of two different intact proteins after resistance exercise. METHODS: Healthy volunteers were randomly assigned to one of three groups. Each group consumed one of three drinks: placebo (PL; N = 7), 20 g of casein (CS; N = 7), or whey proteins (WH; N = 9). Volunteers consumed the drink 1 h after the conclusion of a leg extension exercise bout. CONCLUSIONS: Acute ingestion of both whey protein and casein after exercise resulted in similar increases in muscle protein net balance, resulting in net muscle protein synthesis despite different patterns of blood amino acid responses.
Anyway.... To your diet.
