The Basics: Overview
To stay at a healthy weight, balance the calories you eat 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.
How do I know if I’m at a healthy weight?
Finding out your Body Mass Index (BMI) is the best way to learn if you are at a healthy weight. Use this Body Mass Index (BMI) calculator to find out your BMI and what it means for you.
- If you are overweight or obese, you can lose weight by eating fewer calories and getting more physical activity.
