Calories are the basic unit of energy found in all foods and are necessary to maintain the body's vital functions or basal metabolic rate. The amount of calories a person needs depends on factors like their age, gender, and lean muscle mass.
Eating too few calories for a prolonged period of time causes a person to become underweight (per the BMI) leading to muscle atrophy, weakened immunity, and eventually, organ failure. Conversely, eating too many calories causes a person to become overweight and obese, increasing their chances of heart disease, type II diabetes, and cancer.
Healthy high-calorie foods include nuts, seeds, dark chocolate, dried fruit, avocados, whole grains, milk, dairy, eggs, fish, and meats. The amount of calories a person needs depends on their age, gender, activity level, and muscle mass. The DV for calories is 2000 calories.
