Question:
How do I know if I'm overweight?
Answer:
While BMI (body mass index) is often used to gauge whether a person is overweight, a recent study found that waist circumference is more closely linked with cardiovascular disease. I also consider waist circumference a better measure because it reflects body density.
Further, if you are trying to lose weight, fat loss is more important than total weight loss. Some people lose fat without actually losing much weight, and waist (and hip) measurements can help you track how much fat you have lost.
Your waist circumference should be measured by placing a tape measure around the smallest area below your rib cage and above your belly button.
For men:
- Ideal waist measurement: between 31 and 36 inches
- Overweight: between 36 and 40 inches
- Obese: over 40 inches
For women:
- Ideal waist measurement: between 28 and 33 inches
- Overweight: between 33 and 37 inches
- Obese: over 37 inches
