A strict diet refers to a specific eating plan that limits or excludes certain foods, often for health reasons. This type of diet is typically very restrictive and requires careful planning and adherence in order to achieve desired results. A strict diet may be prescribed by a doctor or nutritionist for medical conditions such as food allergies, intolerances, or chronic diseases like diabetes or heart disease. It can also be followed voluntarily for weight loss, performance enhancement in sports, or to achieve specific health goals. The goal of a strict diet is usually to eliminate certain foods that may cause harm or discomfort and replace them with nutrient-dense alternatives that promote optimal wellness.
