Hey, Spo, I'll try to be as polite as possible when I tell you this. You don't know what you're talking about. Someone who says "ketosis is bad" without a.) ever reading any medical literature (which I have) or b.) losing 50 pounds from ketosis (which I did) has no room to make uneducated assumptions in this manner.
The ketosis that occurs from a low carb diet is referred to by Dr. Atkins as BDK (Benign Dietary Ketosis). When you remove carbohydrates from your diet (not 100% removal, but removal so you're only intaking 20-40 grams per day as opposed to the government, hear that?, government, what?, government "required" carb intake of 300 grams) your body uses its own fat stores for energy, and yes, the breakdown of your lipids does produce ketones which are eliminated in your breath and urine.
Now, this ketosis is not bad. It STOPS once you have no more weight to lose. I'm still on a low carb diet after 2.5 years now, and I don't think I've lost weight in 1.5 years of that time (after I average out all the tiny weight gains and weight losses I've had since then). So you're probably under the assumption that ketosis will break down muscle and organs an all that other good stuff. It won't. If it did, I believe I'd be dead after two years on this diet.
Now enough of that. Lio, consult with your own personal physician, or do your own medical reasearch and then work up a diet that works best for you. Don't listen to what the government tells you that you "should" eat, don't listen to medically uneducated people like myself (although my experience was positive, I have a computer degree on my wall, not a medical degree), or even less medically educated people like Spo. That's all. You looking better and feeling better is for you and you alone, and you should do it the way that's best for you. If that's a low carb diet, great. If that's a low fat diet, great. If that's no diet and working out at a gym like a maniac or running 10 miles every day, that's great too. Do what's best for you, and fuck everyone else.
