The primary characteristic of a high-protein diet is its increased intake of protein compared to other macronutrients such as carbohydrates and fats. Typically, it emphasizes lean protein sources like poultry, fish, legumes, and dairy, while often limiting high-carb foods. This type of diet is popular for its ability to support muscle growth, boost metabolism, and enhance satiety, potentially aiding weight management. However, it's essential to balance protein intake with other nutrients for overall health. Consulting with a healthcare professional is advised for personalized recommendations and to avoid potential drawbacks associated with excessively high protein consumption.
