Not true at all as my weight loss shows.

I started out my weight loss journey doing very LC and frankly felt awful until I upped my carbs ala South Beach. I don't count my carbs but when I've logged into fitday it's generally around 150. I also go lighter on protein than many SBers because animal protein tends to make me feel ill when I eat very much.

Every body is different. Many here rail against carbs but my body needs healthy carbs or I can't function.
