Not necessarily true. For a large majority of us, at some point in our low carb weight loss calorie counting absolutely becomes necessary in order to continue losing. I did fine only counting carbs until I hit about 170. Then I spent the next year trying to figure out how to tweak carbs and so on so I would lose again. People had lots of helpful advice about increasing carbs, decreasing carbs, increasing food and so on. Increasing food only made me gain, even at less than 20 g/day carbs. Then, I tried calorie counting along with low carb and ...Bingo-started losing again. This is very common as people get closer to their goal weight. If I keep calories at around 1,000, I lose. If I get higher than 1,200, I stay the same or gain.
