Understanding Calories In Calories Out

What Does Calories In Calories Out Mean?

The principle is straightforward: the calories you consume are the same amount of energy your body has to use. Whether you are eating, exercising, or resting, your body is constantly balancing the energy coming in with the energy going out. This balance determines whether you gain, lose, or maintain weight.

• If you eat more than you burn, the excess is stored as fat.
• Eating fewer calories than you use leads to weight loss as your body uses stored energy.

How Your Body Uses Calories

Calories from food are used in three main ways: for immediate energy, to build and repair tissues, or to be stored for later use. Your body decides how to use each calorie based on your needs, activity level, and overall health.

• Calories are used for energy and movement, such as walking or exercising.
• Some calories help build muscle and repair your body.
• Extra calories are stored as body fat for future energy needs.
