Obesity is an imaginary word used on a sliding scale.
BMI is bunk. body weight/height ARE up for interpretation. Take for instance a 6′ tall, 215lb athlete, true body fat percentage 4%, but by BMI calculations, 29.2 and overweight-nearing ‘obese’.
Even within BMI, countries have different ‘normalcy ranges’. The calculation is stated as a risk assessment tool, and when coupled with ANY other ‘risks’, can be an indicator for shorter life expectancy. A more general statement is difficult to find when it comes to health.
A more accurate body fat percentage measurement is not performed by your local physician. Hydrostatic body fat testing is a method.
For me, the places I frequent, activities I participate in, people I would classify as adversely overweight are not an overwhelming common sight.
The reality is, we are all in the process of dying, some faster than others by choice, some not by choice, some by random life events.
Are diet and nutrition widely understood, of course not. Are many restaurant options more concerned with profit than raw food quality, of course. Is large scale food mfg/processing ‘made’, and not ‘natural’, yes.
