Final answer:
A BMI value above 25 is associated with increased health risks and is considered overweight, while a BMI of 30 or higher is classified as obese, leading to serious health issues. Morbid obesity is classified as a BMI of 40 or more or 35 with associated health conditions.
Step-by-step explanation:
A BMI value above 25 is associated with increased risks of chronic health diseases. This value is considered the threshold for being overweight with a BMI of 30 or higher categorized as obese. Obesity can lead to a variety of serious health problems, including type 2 diabetes, heart disease and high blood pressure. It is important to note, though, that while BMI is a useful tool for assessing population health it may not be as accurate for individuals due to factors it doesn't account for such as muscle mass in athletes.
Morbid obesity is a more severe form, defined as a BMI of 40 or more, or a BMI of 35 or more in the presence of obesity-related health conditions. Maintaining a healthy BMI through a balanced diet and regular physical activity is vital for reducing the risk of these chronic diseases.
