>> Being fat indicates that a person has made one HELL of a lot of unhealthy choices. Like - every single day, he eats to much.
With respect Runaway, that thinking right there is exactly the problem.
Obese != unhealthy life choices (at least not in all cases)
Take for example the 250lb person who eats right, jogs, and works out every day vs the 145lb person who never exercises, eats cookies, and pounds beer and soda but for some reason never gains a pound. The 250lb person could have a thyroid problem or other hormonal imbalance causing their metabolism to be too slow. Thus they burn less calories and keep weight easier. But they have strong lungs and a good heart. The doctor brow beats them every visit harping on whatever diet and exercise they claim to be doing as not enough, or (if they are bolder) outright lies. This does not help this patient stay healthy.
The 145lb person could have the opposite problem with imbalances causing their body to burn too many calories. They could be skinny as a rail with hypertension and be bordering on becoming Type II diabetic. But the doctor doesn't bother to run any tests or take the results too seriously because they are at their "target weight". This does not help this patient stay healthy.
Doctors should diagnose based on full spectrum data collection. Not simply based on what they see and think at first glance. That's like a climatologist looking at a clear blue sky on a good day and saying "look, no smog. Clearly climate change is not caused by man made pollutants!!! No need to look any further into this."
On second though, perhaps a car analogy would work better. Can somebody help me out here?
