The article is part fact, part wishful thinking.
I lost 30 pounds from a low-carb diet and my health has improved. I used the weight drop to help me get back in to more physical fitness, brought my carbs up some and I will never go back to my previous lifestyle. If you do go on a low carb diet, just don't be too foolish when it comes to fat and egg consumption, which I have seen some people do.
What's your favorite low carb snack?
