Contrary to popular myth, a low-carb diet is not equivalent to
a high-protein diet. Rather, it is actually an adequate protein
diet. Consuming too much protein may cause weight-loss stalls.
(Although increasing your intake of protein won't harm your kidneys,
as you've probably been told. That's a common myth.)
On a low-carb diet, calorie counting is not usually that important,
but the amount of calories you usually consume per day can help
you estimate your protein needs. Most people typically consume
between 1800 and 3000 calories in any given day. To figure out
how much protein you should be consuming, a good rule of thumb
to use in determining your protein requirement is to prepare a
list of foods that you might typically eat in a day (before the
low-carb diet). Add up the calories and see where your typical
daily calorie level falls.
