Specialized diets are eating plans designed to meet specific health needs or lifestyle choices. These diets can be tailored for various reasons, such as managing medical conditions like diabetes or celiac disease, or for personal preferences like vegetarianism or veganism. Each diet typically emphasizes certain food groups while limiting others to achieve desired health outcomes. Common examples of specialized diets include the Mediterranean diet, which focuses on whole grains, fruits, and healthy fats, and the ketogenic diet, which is high in fats and low in carbohydrates. These diets can help individuals improve their overall health, manage weight, or enhance athletic performance.
