I disagree with that end. The purpose is not to reduce calories, the point is to be, feel, and look better. Counting calories is tedious and inaccurate. "Don't eat outside of X window" is much less effort, and anecdotally, has given me better results.

I don't need to know my calories at all, my metabolic system can be a complete black box, and as long as I'm able to do stuff I enjoy without feeling groggy, eat almost whatever I want, and just sacrifice the timing, I'm happy.
