What does a body mass index (BMI) of 30 or more indicate?

A body mass index (BMI) of 30 or more indicates obesity, which categorizes individuals at a higher risk for various health complications. BMI is a simple calculation based on height and weight, and it helps to identify weight categories that may be associated with health risks. The classification system for BMI ranges typically includes underweight (less than 18.5), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obesity (30 and above).

When a BMI reaches 30 or above, it signals that the individual has an excess amount of body fat that may affect their health negatively. This can lead to complications such as Type 2 diabetes, heart disease, hypertension, certain cancers, and other metabolic disorders, making it crucial for individuals in this range to seek medical advice and consider lifestyle changes. Understanding this classification allows healthcare professionals to implement appropriate interventions to promote healthier body weight and reduce the risk of associated health issues.
