Atkins diet is more akin to the way our ancestors used to eat, and what our body got used to, than what we eat now.
Refined carbohydrates never existed before, and what I believe is underlying & principle cause behind the obesity factor.
Yeah, but you can be on a diet that is low in refined carbs without being on a ketogenic (Atkins) diet-- like the "Zone diet" and "South Beach Diet", which are both much healthier than Atkins. Ketosis is what burns the fat in an Atkins diet, and that is NOT the body's natural state. Essentially, by depriving your body of so much carbs, you trick it into thinking it's starving and your body starts burning fat.
