Maybe that works for you, but most of us in the real world have been trying that for years, and with little result. You cannot manage what you cannot measure. A simple, easy to understand, but certainly cumbersome at times system like the hacker diet works well.

Also, you'll stick to your diet longer by eating smaller portions of the food you like than by eating large quantities of food you hate (I'm looking at you, salads). You're better off being hungry than dreading meals.

As always, YMMV.
