Final answer:
High blood pressure, type 2 diabetes, and coronary heart disease are disease risks that increase for people with a BMI greater than 30.
Step-by-step explanation:
Obesity is defined by the body mass index (BMI), which is a measure of a person's weight in kilograms divided by height in meters squared. The normal, or healthy, BMI range is between 18 and 24.9 kg/m². Overweight is defined as a BMI of 25 to 29.9 kg/m², and obesity is considered to be a BMI greater than 30 kg/m². High blood pressure, type 2 diabetes, and coronary heart disease are disease risks that increase for people with a BMI greater than 30.
