The difference between morbidity and mortality

I have already explained the flawed separation of the population to the obese and non-obese, wrongly claimed as NORMAL.

Here I would like to make sure that you understand this flawed claim in the whole context.

I still keep watching related videos to metabolic syndrome, where Dr Lustig participated. This time it was the video The Complete Skinny on Obesity.  At around 10:26 minute you could again hear, how 20% of obese people have normal cellular metabolism and live to a normal age.

Firstly, let me repeat: those people are metabolically normal at a given time. That does not mean they will not develop a sort of metabolic disease later.

Secondly, I accept that the BMI is not an indicator of body fat distribution and even people of normal BMI can have extra fat deposits in their abdomen - increasing the risk for metabolic diseases.

But thirdly: even people with cardiovascular disease can live to a normal age. The statistics say it all: the cardiovascular mortality in the U.S. has decreased over the decades, but it was not the case for the morbidity. The nation is sicker than ever before, it is just the pharmacological and medical advancements that were able to manage the diseases and keep people alive with various conditions. Does that mean people are healthier? Not at all.

I agree that obesity goes with gaining these metabolic diseases and appears as a marker. However, we should not get mislead by saying that obesity does not matter. It makes it worse for 80% of the population suffering clinical obesity, affecting their health by other means than only the metabolism: they suffer sleep apnea, ache in ankles or knees, breathlessness and other physiological consequences of excess body fat. ON top of that, extra adipose tissue of any kind is prevalent among more than half of those with a 'NORMAL' weight, they are just not (yet) obese. Interestingly, almost half of these also suffers metabolic disturbances.
