Unless you have a pre-existing kidney problem, then it would be highly unlikely that a high protein diet (1-1.5g protein per 1lb LBM each day) will harm your kidneys. Most of this "protein toxicity" idea is completely baseless. A high carb diet taxes the pancreas heavily - but we don't hear about "carb toxicity." A diet high in fat forces the liver to secret large amounts of bile to digest the fat - but we don't hear about "fat toxicity." If your thinking about doing the rabbit starvation diet, then you may want to alternate periods of high and low calories to prevent thyroid down regulation. 1 week dieting and then 1 week of maintenance calories should do the trick. Doing moderate amounts of cardio throughout both weeks will help too. Myself, I prefer the Animalbolics diet for fat loss (with a few of my own personal variations). It's where you only eat carbs in the post workout meal. For me, that's 3 large bananas and then I'll throw in about 15g creatine. Then it's back to lean protein for me other meals. The one post workout carb + creatine hit allows my muscle to stay full. This way I can diet down to low bodyfat levels without the flat look of other low carb diets. Justin Hasselman
