Obesity and overweight can increase your risk of high blood pressure.
In fact, recent research has shown that your blood pressure rises as your body weight increases.
Therefore, losing body can help improve your health.
For example, losing 10 pounds can lower your blood pressure, and losing weight offers the biggest benefits to those who are overweight and already have high blood pressure.
Overweight and obesity are also big risk factors for heart disease.
They can increase your chances of developing high blood cholesterol and type 2 diabetes—two more risk factors for heart disease.
So how to know if you are overweight or obese?
Two key measures help you. These are body mass index, or BMI, and waist circumference.
BMI is a measure of your weight relative to your height. It gives an approximation of total body fat—and that’s what increases the risk of diseases that are related to being overweight.
But BMI alone does not determine risk.
For example, in a person who is very muscular or who has swelling from fluid retention (called edema), BMI may overestimate body fat.
On the other hand, BMI may underestimate body fat in older persons or those losing muscle.
That’s why waist measurement is often checked as well. Another reason is that the location of the fat is very important.
For instance, too much body fat in the stomach area can greatly increase disease risk.
A waist measurement of more than 35 inches in women and more than 40 inches in men is considered high.
Overweight is defined as a BMI of 25 to 29.9; obesity is defined as a BMI equal to or greater than 30.
If you are obese, you may have a risk for heart disease and need to lose weight.
You also should lose weight if you are overweight and have two or more heart disease risk factors like smoking and drinking too much alcohol.
If you have normal weight and do not need to lose pounds, you still should be careful not to gain weight.
If you need to lose weight, it’s important to do so slowly. A realistic goal is to lose no more than 1/2 pound to 2 pounds a week.
You can begin with a goal of losing 10 percent of your current weight. This is the healthiest way to lose weight and offers the best chance of long-term success.
There’s no magic formula for weight loss. You have to eat fewer calories than you use up in daily activities.
Just how many calories you burn daily depends on factors such as your body size and how physically active you are.
One pound equals 3,500 calories. So, to lose 1 pound a week, you need to eat 500 calories a day less or burn 500 calories a day more than you usually do.
It’s best to have a combination of both eating less and being more physically active.
And remember to be aware of serving sizes. It’s not only what you eat that adds calories, but also how much.
As you lose weight, be sure to follow a healthy eating plan that includes a variety of foods.
