Doctors around the world say we need to change how we decide if someone is obese. Right now, we use something called BMI, which looks at height and weight. But this does not tell us about a person's health. The doctors say we should look at the person's health and if their weight causes them problems. They say some people with too much fat are healthy, and others are not. They want to call people with weight problems that make them sick 'clinically obese'. People who are not sick but have too much fat should be called 'pre-clinically obese'.

The doctors wrote about this in a report. They say that not everyone with a high BMI is sick. Some people can live well with extra weight. But others have big health problems because of their weight. They cannot walk or breathe well. The doctors want to help people understand the difference. They say we should look at how the body's organs are doing. If the weight hurts the organs and makes daily life hard, the person needs help with medicine. If not, they should get advice on how to lose weight and stay healthy.

The report says that we should use better ways to measure fat. We should look at how much fat a person has around their waist. We should also know about their health history. This will give us a clearer picture. The report will help doctors give the right care to people. It will also stop people from getting treatments they do not need. The report is important because we now have medicines that can make people lose a lot of weight. The doctors want to make sure the right people get these medicines.
