The Basics

What are Overweight and Obesity?
Overweight is a term used to describe someone who is too heavy for his or her height. Obesity means having a high amount of body fat. About two-thirds (over 60%) of Americans are overweight or obese.

How do I Know if I am Overweight?
Finding out your body mass index (BMI) is the best way to learn if you are overweight or obese. Enter your height and weight into this BMI calculator to find out your BMI number and what it means for you.

What Causes Someone to be Overweight or Obese?
Most people become overweight or obese by eating foods high in calories, sugar, and fat and not getting enough physical activity. Genetics and biology can sometimes cause obesity.

Take Action

If you are overweight or obese, you can improve your health by losing just 10–20 pounds. Find out how to get started by clicking on the links below:

Watch Your Weight
If you need to lose weight, do it slowly over time. Try losing 1–2 pounds per week.

Get Active
Aim for 2 hours and 30 minutes of activity a week. Do at least 10 minutes of activity at a time. In addition, do strengthening activities (like sit-ups or lifting weights) 2 days a week.

Eat Healthy
Choose healthy foods and eat smaller portions.

Get Your Blood Pressure Checked
Your blood pressure goes up as your weight increases.

Getting more physically active and eating healthy foods can help you lower your blood pressure and blood sugar. It can help you raise your "good" cholesterol and lower your "bad" cholesterol. It may also prevent heart and blood flow problems that can lead to heart disease and nerve damage.

  • What is a healthy weight for me?
  • How does my weight affect my health?
