It’s easier to track hours of eating than calories.
It’s easier to track sugar/carbs than calories.
It’s easier to track pounds of steak, fish, shrimp, chicken than calories.

Even if you were a medical doctor, or nutritionist, per the literature, your calorie counting would be off by as much as 10-20%.
