BMI Calculator and obesity chart

BMI is a useful measure of overweight and obesity. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.

Although BMI can be used for most men and women, it does have some limits:

  • It may overestimate body fat in athletes and others who have a muscular build.
  • It may underestimate body fat in older persons and others who have lost muscle.

Work on your weight

Changing the way you approach weight loss can help you be more successful at weight management. Most people who are trying to lose weight focus on just the goal of weight loss. However, setting the right goals and focusing on lifestyle changes such as following a healthy eating plan, watching portion sizes, being physically active, and reducing sedentary time are much more effective.

Risk Factors

  • High blood pressure (hypertension)
  • High LDL cholesterol (“bad” cholesterol)
  • Low HDL cholesterol (“good” cholesterol)
  • High triglycerides
  • High blood glucose (sugar)
  • Family history of premature heart disease
  • Physical inactivity
  • Cigarette smoking
Eat Right
To lose weight, it’s important to make lifestyle changes with a focus on reducing calories from food and beverages, a healthy eating plan, and portion control.

Diabetes is a chronic disease, which occurs when the pancreas does not produce enough insulin, or when the body cannot effectively use the insulin it produces. This leads to an increased concentration of glucose in the blood (hyperglycaemia).
