Is displacing carbohydrate increased urinary calcium loss and dehydration are some side effects of high protein intake?

Yes, high protein intake can lead to increased urinary calcium loss and dehydration. When protein is metabolized, it produces acids that the body neutralizes using calcium, which can result in elevated calcium excretion in urine. Additionally, high protein diets may increase fluid requirements due to the need for kidney function to handle the increased nitrogen waste, potentially leading to dehydration if fluid intake is not sufficient.
