Dieters who consume an all-protein diet may develop ketosis, also known as an unhealthy metabolic state. Symptoms of ketosis include a loss of appetite and bad breath, states WebMD. To prevent ketosis, dieters should consume at least 100 grams of carbohydrates each day. High-fiber carbohydrates include whole grains, fruits and vegetables.

To prevent the formation of kidney stones, dieters should eat fruits and vegetables that are high in potassium, reports Women's Health. In addition, dieters should eat less animal protein and more plant protein to reduce acid production in the body. Increased acid in the body aids in the formation of kidney stones and prevents bones from absorbing calcium properly.

Dieters should consult a physician before starting an all-protein diet. If dieters want to add more protein to a diet plan, they should choose lean proteins such as fish, skinless chicken and low-fat dairy products, reports Mayo Clinic. Dieters should also eat high-fiber carbohydrates to help digest food and to help remove bodily waste.
