I have been on the Atkins diet for over five years and was born a type II diabetic which is why I do not eat any carbs. Apart from the distinct smell when I urinate the ketones away, there are no side affects.
This diet has not only helped me lose weight but it stopped all of the symptoms of my diabetes.
I believe the secret to good health and a long life is a zero-carb diet and an aspirin a day. Throw in a 30 minute walk a day and you'll live until you're 100.
Trust me that your breads, pastas, cakes, potatoes, sugar and your wind producing veggies are not doing you any good at all. You will be fat, bloated and end up with all sorts of health problems. I never even get a cold anymore.
Living off body fat is natural because that's why we store it. Living off sugar from carbs is abnormal and none of your body fat is used; it just sits there like flab. Look at a grossly obese person and now ask yourself does that person eat carbs or fats? The answer will always be carbs.
So do yourself a favor and eat zero carbs and once you get used to it and the large variety of food available, to you then reap the benefits.
I don't even suffer from Atkins breath and that too seems like a myth invented by the very people who don't want you to stop spending your money on carbs and of course, vegetarians hate us healthy meat eaters who have iron in our blood.
