Imo I'd do what's best for you and see it based on your results..
They measure your bodyfat, how much muscle etc.. you have but I'm not quite sure how can they know based on that how much grams EXACTLY do you need... But it is helpful 100 % and I'm sure it helps. I just stay hydrated throughout the day, eat proteins whenever I'm hungry, minimise carbs (and drink plenty of coffe for energy lmao) and that's it.. If I feel like my energy sucks or effects my workout I just put in more carbs since they're important part of metabolism..
