I think it may be beneficial for beginners to keep track of their food intake, just to know what they really take in. For my current diet, I stopped all of that. I know that I'm getting enough protein and enough food variety for all nutrients. Calorie restriction works just by experience. That was actually one reason that made me switch to this kind of diet: I'm lazy.
I can only repeat that I have never felt stronger or healthier than on my current diet. That all while eating whatever I want within the scope of P1-P5, and that does include e.g. chinese food, burgers, and ice cream bars.
