Is the diet with high protein harmful? I work on my body and I want to build muscles I don't use any supplements but I eat chicken, egg and meat daily

Some caution. For most healthy people a high-protein diet generally isn't harmful. But some high-protein diets restrict carbohydrate intake too much & can result in nutritional deficiencies or insufficient fiber which can cause bad breath, headache and constipation. Also Some high-protein diets include foods such as red meat and full-fat dairy products, which may increase the risk of heart disease.
