What Obesity is, exactly.

Obesity is a complex health condition that affects millions of individuals worldwide, significantly increasing the risk of various chronic diseases.

As a physician at Missouri Metabolic Health, I believe it's essential to understand the different ways we measure and define obesity.

Here are three key metrics commonly used: Body Mass Index (BMI), waist circumference, and percent body fat.

1. Body Mass Index (BMI)

BMI is a widely used screening tool that calculates a relative number based on a person’s weight and height.

- Underweight: BMI < 18.5
- Normal weight: BMI 18.5–24.9
- Overweight: BMI 25–29.9
- Obesity: BMI ≥ 30

While BMI is a useful general indicator, it does not directly assess body fat or account for muscle mass, bone density, or distribution of fat.

2. Waist Circumference

Waist circumference measures the distance around your waist and helps estimate abdominal fat, which is a significant risk factor for cardiovascular diseases and type 2 diabetes.

To measure waist circumference:
- Use a flexible measuring tape.
- Measure just above the hip bones, usually at the narrowest point of the waist.
- Make sure the tape is snug but not compressing the skin.

Cut offs for obesity: Men with a waist circumference > 40 inches (102 cm) and women > 35 inches (88 cm).

3. Percent Body Fat

Percent body fat indicates the proportion of fat in your body relative to your total weight. It provides a more accurate assessment of body composition than BMI.

Body fat can be measured using various methods, including:
- Skinfold calipers: Pinching the skin at specific sites on the body.
- Bioelectrical impedance: Using a device that sends a small electrical current through the body.
- Dual-energy X-ray absorptiometry (DEXA): A more precise imaging technique.

Cut offs for obesity: Men >25% body fat and women >30% body fat.

Conclusion

Understanding these definitions and measurements is crucial in identifying and managing obesity effectively.
