But recently I read The Schwarzbein Principle (yes I know it's just another low carb book) and she claims that for many people low carb dieting induces too low insulin levels. She doesn't define how low is too low but she claims that too low insulin levels are even more dangerous than too high. She claims that our body should run on a mixture of carbs and fat so very low carb diets are unhealthy. As far as I know if somebody is not diabetic type I even with 0 carb intake his/her pancreas produces some insulin. Any comments ?
