Thank you :) I haven’t planned on writing about this yet but thank you for the idea. A very high protein diet that’s low in carbs and fat can be hard on the liver and kidneys. If calories or the other two macronutrients are low, the body can start converting some of the excess protein to sugar to create more fuel. Ammonia is a byproduct of turning protein into sugar, and the liver and kidneys will have to work harder to get rid of it. Excessive reliance on protein for fuel can eventually really take a toll on the kidneys, especially if someone is very physically active. Additionally, if calcium intake it low, bone loss can become a concern, as the body pulls calcium from bone to buffer the acid load of excess protein. I think a moderate protein intake with a carb intake that meets the body’s needs and doesn’t force it to resort to turning protein into carbs is a better approach, and far less stressful on the body.
