Diet is the habitual pattern of food and nutrient intake that supplies an organism with energy and the macronutrients and micronutrients required for growth, maintenance, and physiological function. Beyond simple energy balance, diet is defined by its composition, the relative proportions of carbohydrate, protein, and fat, and by the overall pattern of foods consumed, which together shape metabolic, cardiovascular, and gastrointestinal health. Dietary patterns are commonly studied as coherent wholes rather than single nutrients, reflecting how foods are combined in real eating behaviour. Several well-characterised patterns recur in nutritional research. The Mediterranean diet, rich in plant foods, unsaturated fats, and moderate intake of animal products, is examined for its associations with cardiometabolic outcomes and its cultural context. Exclusion diets, such as gluten-free or casein-free regimens, are investigated as interventions in conditions ranging from coeliac-spectrum disorders to symptom management in chronic syndromes. Manipulations of macronutrient ratio, including high-protein and high-fat approaches, are studied for their effects on body composition, muscle adaptation, and fat mass. Energy-restricted, or hypocaloric, diets are evaluated for weight management and adherence. Increasingly, the interaction between diet and the gut microbiota is recognised as central to how dietary intake translates into health maintenance and disease risk.
