The Basics: Overview
To stay at a healthy weight, balance the calories you eat and drink with the calories you burn (use up). Calories are a measure of the energy in the foods you eat. To lose weight, you need to burn more calories than you eat.
A healthy diet and physical activity can help you control your weight. You burn more calories when you are physically active.
