Q. How is overweight defined, and what are the common criteria or measurements used to determine it?

Overweight is typically defined as having an excess amount of body weight, often in the form of fat, which can adversely affect health. It's commonly assessed using various criteria and measurements to gauge an individual's level of excess weight.
One widely used method is the Body Mass Index (BMI), calculated by dividing a person's weight in kilograms by the square of their height in meters. A BMI between 25 and 29.9 is generally considered overweight, while a BMI of 30 or higher is classified as obesity. However, it's important to note that BMI has limitations as it doesn't consider factors like muscle mass or distribution of fat.
Waist circumference is another measurement used in conjunction with BMI. A larger waist circumference can indicate excess abdominal fat, which is linked to a higher risk of health issues like heart disease and diabetes. For men, a waist circumference over 40 inches (102 cm) and for women over 35 inches (88 cm) is considered a risk factor for overweight-related health problems.
Health professionals also assess body fat percentage. While there are various methods to measure it, such as skinfold calipers, bioelectrical impedance analysis (BIA), or dual-energy X-ray absorptiometry (DEXA), these are not always easily accessible or practical for everyone.
Understanding these criteria and measurements helps individuals and healthcare providers identify potential health risks associated with excess weight. However, it's essential to consider these measurements as part of an overall assessment of health, including other factors like lifestyle, diet, physical activity, and medical history.
If you're concerned about your weight, consulting a healthcare professional can provide personalized guidance and support tailored to your individual needs. They can help interpret these measurements and work with you to develop a plan for achieving a healthier weight through diet, exercise, and lifestyle changes.
Remember, while these measurements offer guidance, the focus should be on overall health and well-being rather than solely on the numbers on the scale or specific measurements.
