From what I've always understood, the "basic" rule of cutting and bulking is:
Bulking - 500cals over maintenance a day
Cutting - 500cals under maintenance a day
I know of all of the other variables about %'s of carbs, fats and proteins(macros) and not everybody needs that much to bulk.
I've never really been very good at diet, but I am good at conditioning/cardio, so I've never really had a problem losing weight by cutting back cals and carbs and boxing a few times a week.
What I'm getting at is, when you go on a cut, taking out all of the math and variables, and speaking theoretically, what would be the problem with maintaining the same food intake during a bulk and a cut, but burning an extra 1,000 cals a day during a cut, and maybe taking out some carbs. In theory, the 1,000 cals would take you from a 500 cal surplus to a 500 cal deficit or vice-versa if you're going from a cut to a bulk. In theory, this should work, but in reality, you most likely wouldn't get the results you want. Any specific reasons as to why? I'm merely asking for details and more knowledge for myself or anybody else who would want to know.
