A unit of energy within your food is called what?

The term that refers to a unit of energy within your food is the calorie. Calories measure the amount of energy that food provides to the body when consumed. When you eat food, your body breaks it down during digestion, and the energy released is utilized for various bodily functions, including maintaining body temperature, supporting metabolic processes, and powering physical activity. Understanding calories is essential for managing energy intake and expenditure, which plays a significant role in nutrition, weight management, and overall health.

The other options, while related to health and nutrition, refer to different concepts. BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic physiological functions at rest. BMI (Body Mass Index) is a calculation that uses height and weight to assess body fatness and categorize individuals into weight categories. Diet simply refers to the types and amounts of food consumed regularly.
