...I agree with you on the deductive and inductive sources of the problem, but also, disagree. When you have a financial force (aka corporate political) that has greater scope to reach targets, via various specific media-propoganda and cultural assimilation - then the onus is on regulation of/combating that. However, I also agree that, in tandem, it is us as individuals and societal groups that need to take responsibility and address these issues. The main issue is who we submit ourselves to, to create our culture and our values and why do we let this happen?
The internet has enabled us to access much information but the channels of information that people choose to access are based mostly on their/our own set of knowledge; so it is discriminative. Therefore, despite the seeming choice of internet searches of resources it exhasberates people, illiciting confusion and fear and therefore, supplying market need/consumers- this funnels individuals toward their own specific bias. Models like these are deductive; they are purposefully designed to enlighten a specific issue; the result to society is the neglect of the of more pertinent, overall issue - which to the individual remains illusive. Keeping the individual in the dark is problematic for us; is profit for industry. Having breadcrumbs of information can give one a false sense of empowerment and simultaneously, gives the reward of having discovered information that should not be covert in the first place and also, which solely understood in isolation of context, is not factual. There have been many articles published on this - this is not a foreign concept.
If you noticed the nuance of the talk/video, it mentioned the difference between visceral fat and subcutaneous fat. The former being much more malignant.
It is issues like these that are ignored in popular discourse and mostly, discarded with a focus on how the extraneous body looks, or how much BMI or muscle-fat ratio one has. This again, is feeding into a paradigm which elevates healthy looking attractiveness or, a sense of superficial empowerment over actual factual information; again cultural norms fuelled by industry. This is a huge problem and keeps people paying exorbitant gym membership fees ( speaking of the rat-race; the treadmill was never a better metaphor) and buying into the 'heath industry' nonsense. An alternative to this is going outside and exploring the environment and valuing the natural environment. You only have to observe the ubiquitousness of protein laced food; with a shelf-life of eternity to deduce what marketing forces are feeding our culture and lining their pockets. Such propoganda excludes the concept of health as a multi-dynamic system, i.e. focusing on the physical while neglecting the physiological, mental and emotional (also social) factors that all work together.
Obviously, that is not to say that exercise in any form is not good BUT it is a ruse to focus solely on this- especially equating it with the gym - this goes to show how limited our collective perception of health and well-being is and how we have been collectively primed to be senstivie to industry marketing over actual valid health information and self-actualization toward our own health needs.
I agree with you that it is disheartening but disheartening doesn't mean that it can not be challenged.
I've seen people under 22, with knee injuries and worse, from running marathons. Also, obese individuals who cannot walk to the toilet - these are different sides of the same problematic, coin imho.
Biological systems are not deductive, this has been proved over and over. The elitist ignorance that is apparent and success of corporate control of these related areas, has more to do with a cultural veil of, health to the wealthy/middle class wannabes/successful/educated/compliant/winners ( those who 'deserve it') and crumbs to those who are left out of the knowledge equation. Keeps our sociaty ill and unequal. I think it is pretty obvious and it is an illusory trap of fiscal origin.
