As I have mentioned before, the low carb lifestyle is more about fat than protein. It is a high fat, moderate protein, low carb diet. In percentage terms, my macro nutrient breakdown for yesterday is as follows:
Translated into numbers, yesterday, I consumed 165 grams of protein, 29 grams of "arbs" (or "carbs," of which 7 grams were fiber, for a net carb total of 22 grams), and 230 grams of fat. My total calories consumed yesterday came to 2,808 but, according to this software, I also walked the dog for 330 calories, making my net caloric intake yesterday 2,478 calories. The database at this site is very extensive, the best I have seen.
So while I do not really track calories (I only track grams of carbs and I am still losing weight), this was a very useful software tool for tracking macro nutrients and for getting a picture of what I am eating.
