RE: whey VS...
Protein is protein, whether it's from food or supps. Best to get it from real food as you get all the other stuff that coems with it.
Whey is useful as, if it is taken in water or fruit juice, enteres the body very quickly. This is great when your body is catabloic (morning) as it gets you going, or after a heavy workout (when your body is anabolic and screaming for protein). You give it what it wants, when it wants.
At evenings you want slow release protein that can go into your system slowly all night to prevent catabolism. A flow release like muscle milk wouldd do this, as would whey in full fat milk, whey and nuts, whey and flax/cod liver oil - basically fats will slow down the absorbtion. Other people just use something natural like cottage cheese.
Any protien is good, just take reguarally throughout the day with each meal. maybe slightly more pwo (fast absorbing) and ppwo as these are when you need it most. 1.5g per 1 lb of body weight is a typical guide.
I'd go for whey (it's cheap) and if you want slow release eat it with efas. But try and get as much as you can from food like tuna, chicken, lean mince, other oily fish etc.
I get my whey 80 from myprotien.co.uk
