Obesity is a complex disorder involving an excessive amount of body fat. Obesity increases your risk of diseases and health problems such as heart disease, diabetes and high blood pressure.

The good news is that even modest weight loss can improve or prevent the health problems associated with obesity. Dietary changes, increased physical activity and behavior changes can help you lose weight. Prescription medications or weight-loss surgery may also be options for treating obesity.

What you can do?

  • Exercise. Aim for 30 to 60 minutes of moderately intense activity daily.
  • Set goals focused on specific healthy activities such as improving muscle tone through strength training or starting a daily food and activity diary.
  • Consider weight loss surgery if you're concerned about weight-related health problems. See your doctor to evaluate your health risks and discuss your weight-loss options.
