but what is this all about?

"Also, a diet without carbohydrates causes the body to make substances called ketones that may create a mild nausea, suppressing hunger."

A mild nausea? Is there anything to this? Or is the word "may" in there just to CYA (or CHA, for grammar's sake)? It seems kind of irresponsible to be telling people that Atkins & low-carb will make you feel nausea if there isn't some scientific basis for it. It's like she's grasping for any straw she can get her hands on. Does she really think that millions of us would walk around & keep low-carbing if we felt nauseous all the time? Because that's so much fun. How counter-intuitive is that? I don't care how much weight I can lose, if I'm walking around thinking I'm going to be sick all the time because of my diet, you can bet I'll be changing what I eat.
