Reaching and maintaining a healthy weight is important for overall health and can help you prevent and control many diseases and conditions. If you are overweight or obese, you are at higher risk of developing serious health problems, including heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers. That is why maintaining a healthy weight is so important: It helps you lower your risk for developing these problems, helps you feel good about yourself, and gives you more energy to enjoy life.
Energy balance is important for maintaining a healthy weight. The amount of energy or calories you get from food and drinks (energy IN) is balanced with the energy your body uses for things like breathing, digesting, and being physically active (energy OUT):
- The same amount of energy IN and energy OUT over time = weight stays the same (energy balance)
- More energy IN than OUT over time = weight gain
- More energy OUT than IN over time = weight loss
To maintain a healthy weight, your energy IN and OUT don’t have to balance exactly every day. It’s the balance over time that helps you maintain a healthy weight.
You can reach and maintain a healthy weight if you:
- Follow a healthy diet, and if you are overweight or obese, reduce your daily intake by 500 calories for weight loss
- Are physically active
- Limit the time you spend being physically inactive
