High-protein diets are usually rich in meat, dairy products and eggs

A high-protein diet is a diet in which 20% or more of the total daily calories comes from protein.[1] Most high protein diets are high in saturated fat and severely restrict intake of carbohydrates.[1]

Example foods in a high-protein diet include lean beef, chicken or poultry, pork, salmon and tuna, eggs, and soy.[2] High-protein diets have been criticized as a type of fad diet and for promoting misconceptions about carbohydrates, insulin resistance and ketosis.[1][3]

A 2017 review indicated that a high-protein diet may contribute to life-long risk of kidney damage, including chronic kidney disease.[4] High-protein diets may increase the risk of coronary artery disease and cancer.[3] A 2020 review found that a high-protein diet does not significantly improve blood pressure and glycemic control in people with diabetes.[5]

The American Heart Association’s Nutrition Committee have issued a strong recommendation against high-protein diets such as Protein Power and the Atkins diet.[3] The committee noted potential health risks of high-protein diets and how there are no long-term scientific studies to support their efficacy and safety.[3]

The following high-protein diets have been criticized as fad diets:[1][3][6][7]
