If your BMI is 25 or above, you are overweight; if it is 30 or above, you are obese. It is a good idea to talk to a doctor or nutritionist about how you can lose weight. This is especially true if you have any of the following factors that increase your risk of developing serious weight-related health problems:

• If your waist circumference is 35 inches or above for women or 40 inches or above for men, this tends to increase the health risks associated with excess weight.
• If you tend to have an “apple” shape to your body in which your body is thickest around the tummy area (as opposed to in the thighs or lower body), you have a higher risk of developing health problems associated with obesity.
• If you have a BMI of 40 or above, you are considered morbidly obese and are at very high risk of serious health consequences.
• If you have other medical conditions already such as high blood pressure or diabetes or if you have a family history of obesity, cardiovascular disease, diabetes, high blood pressure or sleep apnea, you may be at increased risk of developing weight-related complications.
