Just a note here...low carbing is not eating "tons" of protein, it's eating adequate amounts of protein and there has not been a single study done which proves that eating even high amounts of protein is harmful to your body in any way. It's just been quoted so often that people assume that there must be a study somewhere that proves it. I'd be more concerned about the long term health risks of eating high carb/low fat than I would about eating this way since more and more studies are coming out showing that high amounts of refined carbs in the diet ARE harmful to your health in the long term, especially when paired with high amounts of the wrong types of fat.
