The science of nutrition and bodybuilding doesn't support the bulk-up-then-cut method. There's a limit to how much lean mass your body can produce. That limit is a pretty complex function of several variables, and it varies greatly individually.
But the critical variables are ones you can work with in order to optimize your lean gain without adding much non-lean weight that you'll have to cut later. They are your: current gross amount of lean mass; body fat ratio; calorie burn; resistance work effort.
The most effective nutrition and fitness schemes for clean-lean gain are ones that pair the Mediterranean, paleo/caveman, or testosterone-boosting type diets with a weekly fitness regimen focused on a few intense workouts featuring heavy weight loads and short rest periods. The workouts simultaneously work your muscles in ways that trigger muscle fiber growth while quickly depleting your glucogen stores, focing your body to burn fat. And the diet gives your body plenty of fuel to build lean tissue while avoiding excess carbs and indigestible fats that would get stored as non-lean tissue.
Here's a pretty good Men's Health article
that covers the science and some strategies.
