As long as you can deal with the lactose, you can drink as much milk as you like. But not many people can. Whether you're bulking or cutting makes no difference as long as the milk products fit your macros. Maybe cut out the milk before shows depending on how you react to it.
what're people's opinions on yogurt and cottage cheese? i'm not talking about the sugar-laden crap. I mean like Fage.
The calorie's-a-calorie crowd would tell you it's great as it's fairly high in protein and lowish in carbs and no added sugar. However, historically bodybuilding community has shun dairy as it will cause most to hold a film of water if you're lean and then there are the digestion issues that most will have to deal with. I've even heard that dairy will cause a halt to any fat-burning (can't remember why) although that sounds like nonsense.
I know for people competing it's a no-no but what about for everyone else?
I get great results cutting and bulking with cottage cheese as one of my main sources of protein. It doesn't stop fat loss at all if you're at a deficit. It's delicious, filling, and low in calories for the amount of protein you get.
