If it wasn’t reason enough to try and reduce your protein intake because of the environmental effects of protein processing (see http://www.ecomerge.blogspot.com/2012/10/animal-based-protein.html and http://www.ecomerge.blogspot.com/2012/10/environmental-cost-of-protein.html), the personal health benefits of reducing a high protein diet may just convince you. People may think that high-protein/low-carb diets lead to weight loss. The issue is when people consume lots of protein and few carbohydrates, their metabolisms go into a state of ketosis, when the body changes from burning carbohydrates for fuel to burning its own fat. Ketosis is a problem because it tends to suppress appetite and increases the body's elimination of fluids through urine, resulting in a loss of water weight. There is also evidence that suggests that people who eat high-protein diets excrete excess calcium in their urine, and the loss of too much calcium can lead to osteoporosis. Animal based proteins are also usually high in saturated fats, which increase the risk for heart disease, stroke, diabetes, and several types of cancer.
