Definition of a Calorie

• The term "calorie" is often misused. A calorie is as a unit of energy. Without calories we would not have energy. However, it is important to keep our calories at a level that is good for our bodies.
  
  

Amount of Calories

• The amount of calories a person should eat depends on the person's weight, height, age and exercise regimen. The World Health Organization states at the lowest, recommended calorie intake for adults per day is 1,200. However, it is recommended to reach between 1,400 and 1,500 calories per day.
  
  

Basal Metabolic Rate (BMR)

• According to Anne Collins' Weight Loss Program, an individual's calorie intake should not fall below the basal metabolic rate, which is the amount of calories burned by the body.
  
  

Nutrition Information

• The amount of calories in food is not the only information one should look at on a nutrition label. It is important to select foods that are high in fiber, vitamins and protein.
  
  

Empty Calorie Foods

• Avoid empty calorie foods, such as candy, soda, baked goods and fried foods. According to Wellsphere, empty calorie foods lack vitamins, minerals and fiber.
