You need to consider the term obese in relation to the measurement of BMI.
Body Mass Index (BMI) is a person’s weight in kilograms divided by the square of height in meters. A high BMI can be an indicator of high body fatness.
To calculate BMI, see the Adult BMI Calculator or determine BMI by finding your height and weight in this BMI Index Chartexternal icon.
If your BMI is less than 18.5, it falls within the underweight range.
If your BMI is 18.5 to <25, it falls within the normal.
If your BMI is 25.0 to <30, it falls within the overweight range.
If your BMI is 30.0 or higher, it falls within the obese range.
Obesity is frequently subdivided into categories:
Class 1: BMI of 30 to < 35
Class 2: BMI of 35 to < 40
Class 3: BMI of 40 or higher. Class 3 obesity is sometimes categorized as “extreme” or “severe” obesity.
BMI does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, underwater weighing, dual energy x-ray absorptiometry (DXA) and other methods. Furthermore, BMI appears to be strongly correlated with various adverse health outcomes consistent with these more direct measures of body fatness.
So BMI is generally considered to be a good indicator. It also a parameter that is relatively easy to calculate for big groups of people. Note that being obese comes over and above the range of overweight.

You would have to be seriously fit before that becomes a problem. For most people it is a pretty good indicator. In order to qualify as Obese you need to have a BMI over 30. Look at the above scale and calculation! So unless you are a serious sporting person it is likely that you have an issue. But as I mentioned before, BMI is an indicator and a doctor would check a few other things first.
For the last 8-9 years I am under constant and strict supervision regarding my diet/metabolism. I am on a constant (restrictive) diet more or less all the timeMy doctor/dietist will always measure the following with every visit. They do calculate BMI as well, but the below is what determines I can eat!
- weight
- % fat % muscle
- waist circumference
- Upper leg circumference
- blood pressure and heart rate

Numbers are staggering, out of the 650 Million obese globally, we have 135 Million, something to think about. |

I don’t think comparing absolute numbers is very useful. Percentage in a country (as shown in the table) is probably more relevant. The effects (economic and social) tend to be very local.
So lets take as an example my wife’s home country Barbados. A small island in the West Indies. Population about 275.000. 41% of women and 22% of adult men are obese. Which means that the number of diabetes 2 patients on the island is going ballistic. One way or the other, it tends to be society at large that takes the burden of of this. (similar to people living longer). This one is a real problem, people become ill, need to be looked after, people can do less work, tend to loose limbs etc.

Not sure, see also my reference to Barbados mentioned above. In many of these (former colonised) countries you also see a massive shift in diet over the last couple of decades.
