What are calories? arrow top

Calories are a form of energy. When we talk about calories in food, we mean the energy that the food supplies to a person's body. When we talk about calories and physical activity, we mean the energy that your body uses ("burns") to do the activity.

To stay at a healthy weight, you want to take in around the same amount of calories as you use for activity. Are you active a moderate, or medium, amount? (That means something between sitting around a lot and walking more than 3 miles per day.) If so, you probably can eat around 2,000 calories each day.

Sometimes, girls think they need to be thinner, even if they are not overweight. You may see models in magazines or on TV who are really skinny, and you may think that you need to lose weight so you can look like them. But many of these models are underweight to a point that is unhealthy.

So how do you find out if you are a healthy weight? One tool that can help tell if you are at a healthy weight for your age and height is the Body Mass Index (BMI). Talk with your doctor about BMI and your weight. Together, you can decide whether you need to lose weight, gain weight, or stop worrying about your weight.
