According to a document by The National Institutes of Health, approximately 97 million Americans are either overweight or obese. Obesity, in particular, is a serious problem that raises your risk of conditions such as diabetes, stroke, heart disease, cancer, sleep apnea and osteoarthritis. Exercise is a key factor in reversing obesity and leading a healthier life.
Definition
Obesity is a condition of being severely overweight as determined by a body mass index measurement. The body mass index, or BMI, is derived by using a formula that calculates the ratio of weight to height. A BMI of between 25 and 29 equals overweight, while a BMI of 30 or more is obese.
Exercises
If you are obese, exercise will definitely be on the agenda as a prescription to get your weight down. If you are using a trainer, it is wise to get a written note from your doctor, clearing you to proceed and stating any limitations. Much of your exercise program will depend on your physical limitations, but walking is always a good start. Swimming is also an activity that is gentle on joints but will start to burn off calories. You can add resistance training if you are more mobile and your doctor approves.
Precautions
To ensure a safe and productive exercise experience, you must follow certain precautions. Let your trainer know about any pre-exisitng conditions you may have, such as diabetes or heart disease, so any program can be crafted accordingly. Also, be sure you listen to your body's signs as you exercise. If you experience shortness of breath, tingling, dizziness or chest pain, stop what you are doing and seek medical attention. Avoid pushing yourself just to push yourself.
Benefits
As you progress with an exercise program, many of the dangers and risks of obesity will diminish. You will lower your risk of heart disease, stroke and diabetes, your blood pressure will lower and your blood sugar will even out. Your metabolism will rise, which will help you maintain any weight loss you have achieved, and your self-esteem will get a boost.
Considerations
While an exercise program will do wonders for obesity, it is only half of the equation. Modifying what you eat is equally important. Moving away from high-fat, high-sugar fast foods and junk foods and toward a healthier diet will multiply your results. Ask your doctor or dietitian for help creating a diet that is right for you.
