What Is BMI?
Body Mass Index (BMI) is a simple calculation—your weight divided by the square of your height—that helps screen for obesity and related health risks. It’s closely linked to other measures like waist circumference and waist-to-hip ratio.
Why a BMI of 20–25 Is Ideal
A BMI between 20 and 25 is considered healthy. Benefits include:
- Longer life expectancy and lower cardiovascular risk
- Easier weight management if you do gain pounds
- Reduced chances of type 2 diabetes, high blood pressure and certain cancers
Health Risks of Obesity
Obesity greatly raises the risk of serious conditions, such as:
- Type 2 diabetes and heart disease
- Hypertension, high cholesterol and elevated blood sugar
- Several types of cancer
With excess weight, physical activity becomes harder and losing pounds more challenging—a cycle that can worsen these health threats.
