Dietary regimens refer to structured eating plans designed to promote health, manage weight, or address specific medical conditions. These plans often include guidelines on food types, portion sizes, and meal timing. Common examples include the Mediterranean diet, which emphasizes fruits, vegetables, whole grains, and healthy fats, and the DASH diet, which focuses on reducing sodium intake to lower blood pressure. Individuals may choose dietary regimens based on personal health goals or recommendations from healthcare professionals. Some regimens are tailored for specific needs, such as gluten-free diets for those with celiac disease or ketogenic diets for weight loss. Following a dietary regimen can help improve overall well-being and nutritional balance.
