Well ..it's easier said than done. I'll venture to say that you don't have a weight problem. Probably never had. I'll also venture to say, without any judgment one way or the other, that there is SOME undisciplined part of your life that's not quite up to SAE/API standards. Obesity is just a very apparent and visually displeasing problem ..so we tend to regard it with a more critical view if we don't share the condition.
You can have this attitude toward obesity if you're a flaming alcoholic ..an obsessive gambler ..or any number of "defects of personality" and think that you're perfectly alright since you weigh within 10 lbs of your high school weight. Many smokers who are alcoholic and wife beaters are slim and trim
(extreme examples just to make the point).
This is the usual format. Those who never had weight challenges, typically cannot cross identify with other challenges that they face and fail at. Hence they've found their infidel to flog.
Now, I'll surely go with the notion that you don't like looking at fat people. Some are really visually revolting, but I think that the assumption that they're any more "defective" than any number of other people is misguided.
Now heres one for those who reject the metabolism or genetic aspects to this obesity issue.
Take Shak O'Neil and Kareem Jabbar
. Both are about the same height and both were about at the same level of physical activity. You will never get O'Neil to look like Jabbar outside of a concentration camp ..and maybe if you attempted to treat Jabbar like Cobey beef you may put some pounds on him.
If Shak stops being physically active ..he'll be one lazy sack of **** if you don't already regard him that way (not the lazy part). Jabbar will be a skinny freak with, maybe, a pot belly. Which one is "undisciplined"?
This template example works for mere mortals too. I'm 6'1" with a 30" inseam ..most others are a 33-36" inseam for that height. The lean jean crowd in my height peer group will never be capable of being power lifters ..at least not to the extent that I could reach in the same capacity. I'm built for it. Mr. long distance runner ..isn't.
Now sure, anyone can keep in shape if they applied the right amount of time and effort ...but it's usually those who require very little time or effort to maintain their visually pleasing appearance that are more critical of those who may in fact put forth much more effort than they do, to much less apparent effect.
Again, some fat people are pretty hard to look at ..so I don't necessarily have issue with attitudes that are poised from that view.
Let me add that there is no "magic" when it comes to this (and other) issues. I can't say that I struggled with this all my life ..even though I gained about 3-5 average annually over a very long time. I was always strong enough and healthy enough to make others, who were in leaner condition, look like wimps in my raw power when the need for "beef" was apparent. That is, I wasn't "insecure" in my largeness. I played volleyball and basketball @ 265-280 ..and many a lean jeaner got the surprise of their game getting rejected at the net and in the paint.
So ..was I "undisciplined" ..sure. Did I care as long as I could satisfy my personal needs for self esteem.
My son is overweight ..by any standard you can measure. He can also bench 350 for reps and leg press around 500. His arms are bigger than my thighs were when I was in my 20's. He bypassed most of my suits that I wore in my late 20's as a teenager.
What do you think he's going to look like at 45? Is he inherently a lazy sack of ****?? Maybe ...but I doubt that anyone who isn't, and not his fried, would say it to him without a clear exit strategy. Luckily, he subscribes to his father's philosophy of extending goodwill to all ..and to forgive those who trespass against him.
