Too Much Protein, Too Little Water
Research has found that high-protein diets can dehydrate you. Research from the University of Connecticut studied low, medium, and high-protein diets. Participants on the high-protein diet were far more dehydrated than people on other diets. Perhaps this happens because of the nitrogen in protein.
Researchers discovered that high protein causes the kidneys to create more concentrated urine. Protein produces more nitrogen in the blood, which prompts the kidneys to work harder. If you’re going to eat a high-protein meal, drink plenty of water.
