Not sure why you're reacting that way; I don't mind alternative views. The only problem is that your statements are inaccurate. For starters, Atkins died of a head injury acquired in a fall. Secondly, actual research on low carb diets don't support your statement as well.
Lowering your carb intake isn't problematic for nursing, because women for a millenia have eaten less carbs then we have and done fine. You might just pay attention to making sure you get enough fat (coconut oil, etc.) to keep your blood sugar stable. Many athletes find that changing the ratios of what they eat has them less fatigued and hungry, and this is mostly due to reducing their carbs (I'm not saying NONE, I'm just saying less) and increasing fats. Thanks for asking!
Yes, this is all accurate (biochemistry to the rescue!) and is exactly what I explain to athletes who think they need carbs to function. I didn't mention it because, yes, there isn't enough time, and because if I put people on a full ketogenic diet, many can't really make that work long-term. We try to find a middle ground, it's just that the middle ground on carbs and sugar is nowhere people think it is ;-)
Well, it's probably not great. Why eat only protein and cheddar cheese? What happened to vegetables? :-) Variety is also very very important — your body doesn't like only eating the same things. Quality also counts, since if you were only eating grass-fed beef, you'd be doing better than eating sandwich meat.
