The Calories IN Versus the Calories OUT
Too Much In To Burn Off!
Obesity is when you have too much body fat, as opposed to extra weight caused by muscles or water retention. The major cause of obesity is taking more calories in than you burn off with exercise or daily living.
Am I overweight?
One way to find out if you're overweight is to calculate your body mass index or BMI. People with a BMI of 25 or higher — especially people with a BMI over 30 — should consider losing weight to protect their health. Health benefits start even after a weight loss of just 5 to 10 percent of your body weight.
Doctors are still learning exactly how obesity contributes to heart disease, but here's what's known so far:
* Extra weight, particularly around the waist, increases your risk for diabetes and heart disease.
* People who are obese are 3 to 10 times more likely to have high blood pressure, which is a risk factor for heart disease.
* Obesity raises levels of cholesterol and triglycerides (types of fat) in your blood.
* Excess weight increases your risk of arthritis of the hips and knees.
In addition to knowing your BMI, it might also be helpful to figure out your waist-to-hip ratio. Measure around your waist, and then around your hips. If your waist size divided by your hip size is greater than 0.9 to 1.0 for men or 0.8 to 0.9 for women, you're more likely to have heart trouble.
It might not be as hard as you think to lower your health risk. Studies show that cholesterol and blood pressure get better with a weight loss of just 5 to 10 percent. For some people, this could be as small as 10 or 15 pounds.
