Overweight - body mass index; Obesity - body mass index; BMI
Nearly 2 out of every 3 adults in the United States are overweight.
Experts often rely on a formula called the body mass index (BMI) to determine if a person is overweight. The BMI estimates your level of body fat based on your height and weight.
The risk of many medical problems is higher for adults who have excess body fat and fall into the overweight groups.
CHANGING YOUR LIFESTYLE
An active lifestyle and plenty of exercise, along with healthy eating, is the safest way to lose weight. Even modest weight loss can improve your health. Get support from family and friends.
Your main goal should be to learn new, healthy ways of eating and make them part of your daily routine.
Many people find it hard to change their eating habits and behaviors. You may have practiced some habits for so long that you may not even know they are unhealthy, or you do them without thinking. You need to be motivated to make lifestyle changes. Make the behavior change part of your life over the long term. Know that it takes time to make and keep a change in your lifestyle.
Work with your health care provider and dietitian to set realistic and safe daily calorie counts that help you lose weight. Keep in mind that if you drop pounds slowly and steadily, you are more likely to keep them off. Your dietitian can teach you about:
