diet
Meaning of diet: Diet refers both to everything a person routinely eats and drinks and to a specific eating pattern prescribed for a medical condition.
Definition of diet
Diet, in its broadest sense, refers to everything a person regularly eats and drinks, encompassing overall eating patterns rather than any single meal or food choice. This general use of the term underlies much of nutrition science, which studies how different dietary patterns relate to health and disease over time.
In a clinical setting, diet also refers to a specific eating plan recommended or prescribed to address a particular health condition, such as a diet that limits sodium for a person with high blood pressure or one that restricts certain nutrients for a person with kidney or metabolic disease. These therapeutic diets are tailored to a specific medical need rather than describing general eating habits.
Because diet can refer to either a person's everyday eating pattern or a specifically prescribed plan, the surrounding context, such as whether the word appears alongside a particular condition, usually clarifies which meaning is intended.
Used in a sentence

Good to know
Diet used in its general sense, meaning everyday eating habits, is distinct from a diet prescribed for a specific medical condition, and the surrounding context usually indicates which meaning applies.
