In instances of bulking, re: nutrient timing, it's an individual choice. Primary goal is getting in the required nutrients you need in order to allow your body to make gains. Some people prefer to taper calories, and some people don't.

I prefer to taper them, centering my carbs around breakfast, pwo, and ppwo (and that's with training being after my am meal). My afternoon meals are more just proteins, fats, and veggies with fish oils in two of those.

Protein levels stay the same in each meal. Be sure you're getting enough to support the muscle growth.

In terms of your fat gains, that's going to lie more in your caloric intake than it is in nutrient timing. First thing you've got to remember though, is that in order to make sufficient gains in mass, you're most likely going to have to have some fat gain in there too. It IS possible to make mass gains with little to no BF accumulation, however it tends to be a lot longer process with very strict calorie monitoring. Which is something most people aren't very akin to doing during a bulking phase.

If you feel as though you're accumulating fat in your midsection too rapidly, then chances are you're ingesting a higher level of calories than you're really needing. Back off your calories a bit and see how things go (generally you want to be 500 cals over maintenance/day in order to make a 1 pound lbm gain/week).

It's trial and error on an individual basis to see what you need to do in order to make the gains you want with a level of fat gain that you're comfortable with.
