Study confirms long term weight loss on a very-low carbohydrate diet does not adversely affect the kidneys.
Oh dear... The scientific evidence continues to pile up that, when compared to low fat (high carb) reduced calorie diets, low-carb diets are:
1) more effective for fat loss
2) associated with less chronic disease (diabetes, cancer, alzheimers, PCOS, etc)
3) cardio-protective... ie they are good for your heart
But the final, lone stronghold of the carb-loving naysayers was that a low carb diet must be hard on the kidneys in the long term because of the higher protein intake. However, as the above linked study points out "to date, no well-controlled randomized studies have evaluated the long-term effects of very-low-carbohydrate diets on renal function". As in, nobody has ever bothered to check whether this was actually the case! When somebody finally did the study what they found was that "long-term weight loss with a very-low-carbohydrate diet does not adversely affect renal function." So there you have it. Not a leg left to stand on...
