You don't need to take pre-workout to keep energy levels up.
It's all in what you eat.
Of course, you would be restricted when cutting, that's where supplements help.
As long as I have complex carbs before and after my workout, I am able to maintain good energy level at the gym.
Right now, I still eat clean, but I've increased by carbs intake.
I don't mind gaining some fat before the next cut cycle, since I am on sort of bulking/strength program.

The diet I followed during my cat early this year was carb cycling, 4 days low carbs, and carb up every 5th day.
Low carb diet is designed to burn fat for energy, but your body is too smart to be fooled. If you are always on low carbs, your body will adapt and you'll loose the benefits. That's why you cycle carbs, to confuse your system.
