Many health care professionals also measure around a person's waist to help guide treatment decisions.
This measurement is called a waist circumference.
Treatments for obesity include lifestyle changes, medicines and weight-loss surgery.
Your body can meet the majority of your calorie requirements from stored fat, but total starvation is fatal in 8-12 weeks, regardless of initial body weight.
Within one or two days of your last meal, your body will have exhausted all the glycogen stored in the liver and muscles.
Having overweight or obesity increases your risk of developing conditions that can lead to heart disease, such as high blood pressure, high blood cholesterol link, and high blood glucose.
In addition, excess weight can also make your heart have to work harder to send blood to all the cells in your body.
