The Eatwell Guide is the official UK government framework for healthy eating, showing recommended proportions of different food groups. It serves as an educational reference for balanced nutrition but is not prescriptive for individuals.

All macronutrients (carbohydrates, proteins, fats) provide energy measured in calories. Carbohydrates and proteins provide 4 calories per gram, while fats provide 9 calories per gram. Each plays distinct roles in metabolism and bodily functions.

Body composition refers to the proportion of different components in the human body: fat mass, lean muscle mass, water, and bone density. It differs from total body weight because individuals with the same weight can have different compositions.

Processing can affect nutrient density, fiber content, and food structure. Some processing preserves nutrition, while other methods may reduce certain nutrients. Whole foods typically retain more original nutrients than highly processed alternatives.

Satiety is influenced by hormonal signals (such as leptin and cholecystokinin), food volume, fiber content, and gastric stretch. Both biological mechanisms and food composition play roles in how full a person feels.
