Obesity in women is on the rise. Overall, about one third of all women are obese. But some groups of women suffer more. Obesity is measured with a body mass index (BMI), which shows the relationship of weight to height. As a woman’s body mass increases, so does her risk for serious health problems. Some of these problems include heart disease, type 2 diabetes, high blood pressure, and some cancers. A woman’s weight is affected by how much physical activity she does, her diet, and her genes. So having a healthy diet is one of the most important things you can do to help your overall health. If you burn as many calories as you take in, your weight remains the same. If you take in fewer calories than you burn, you will lose weight. So make sure the foods you eat are healthy ones that will work hard for your body.
