A high-protein diet is a dietary approach that emphasises the consumption of foods rich in protein, with the aim of increasing the proportion of protein in one’s daily caloric intake. This diet typically involves getting a higher percentage of your daily calories from protein sources compared to carbohydrates and fats.

Protein is an essential macronutrient that plays a crucial role in various bodily functions, including muscle building and repair, immune system support, and the production of enzymes and hormones. 

General Dietary Guidelines suggest 10-35% of our energy needs should come from protein, whereas a high protein diet is considered to have protein values of over 35% (Marta Cuenca-Sánchez 2015) (Samuel 2014).
