More people are overweight today than ever before. In fact, almost 70 percent of Americans aged 20 and older are overweight. And of those, about one third are considered obese. Unfortunately, the problem has become much more common in children, too. Surprisingly, 17 percent of children aged are obese, and 10 percent of children aged Being overweight or obese are both terms for having more body fat than what is considered healthy.
Both are used to identify people who are at risk for health problems from having too much body fat. However, the term "obese" generally means a much higher amount of body fat than "overweight. Everyone needs some body fat for energy, heat insulation, and other body functions. But having too much can lead to serious health problems. The more body fat you have, the greater your risk for diabetes, kidney disease, heart disease, and other problems.
The most common way is to figure out your body mass index BMI. BMI is a quick and simple way to help identify people who are overweight or obese. It allows you to compare your weight to what is considered "normal" for an adult with your same height. If your excess weight is mostly around your middle apple shape , you are more likely to develop health problems than if the weight is around your hips pear shape. The greater your waist size, the greater your health risk.
To learn more, ask your healthcare provider to measure your waist. If you are overweight or obese, you have a greater chance of developing diabetes or high blood pressure, which are the leading causes of kidney disease and kidney failure.

Or is it more than that? Well, there is a medical definition of obesity , as well as for the term overweight. A 5-footinch woman, in other words, would be better off weighing pounds than Willett has co-authored studies finding the opposite effect.
They argue her study conflates normal-weight, healthy people with formerly overweight people who lost weight due to liver disease, cancer, or some other illness. Having those individuals in the pool of normal-weight people makes the normal-weight people seem sicker, and the overweight people seem healthier, than they actually are. In , Willett and dozens of other researchers from around the world published a paper in The Lancet analyzing studies and millions of study subjects.
Their takeaway was clear: Above the normal weight range, the fatter you are, the higher your risk of premature death. Flegal takes issue with how Willett and his colleagues selected the studies for their review. In the s, the BMI that was associated with the lowest risk of death was Nordestgaard, a clinical professor at the University of Copenhagen and an author of that study, speculated that this could be because over time, doctors have gotten better at treating some of the side effects of excess weight, like high blood pressure and high triglycerides.
But when reporters found that Lavie had received money from the Coca-Cola Company for speaking and consulting on obesity, it fueled speculation that junk-food companies are promoting the supposed benefits of obesity in order to evade blame for causing it. Find and continue a behavioral weight-loss program. When you are choosing a behavioral weight-loss program, you may want to consider whether the program should: offer the service of multiple professionals, such as registered dietitians, doctors, nurses, psychologists, and exercise physiologists.
When selecting a program, you may want to ask about: the percentage of people who complete the program. Monitoring your condition and its health risks. Assess your weight loss since your last visit. A weight loss of approximately five percent in an overweight patient may improve the function of the fat tissue and help lower bad cholesterol and other substances that can predispose to complications. Measure your waist circumference if you are an adult.
If your waist circumference is greater than 35 inches for women or greater than 40 inches for men, you may be at risk for heart disease, stroke, or type 2 diabetes. South Asians and South and Central Americans have a higher risk of complications, so waist circumference should be smaller than 35 for man and 31 for women. To correctly measure your waist, stand and place a tape measure around your middle, just above your hip bones. Measure your waist just after you breathe out. Order blood tests to screen for complications.
A lipid panel test can check if you have high cholesterol or triglyceride levels in your blood. A liver function test can determine if your liver is working properly. A fasting glucose test can find out if you have prediabetes or diabetes.
