People are eating themselves to death.
I'd consider that to be something of a problem.
Some people consider it to be a matter of personal pride.
Well...to be fair, if you take it out of context...people do the same thing with smoking & alcohol. We know what smoking does to your lung, how it can cause cancer, the annual cost of smoking, etc., and yet a ton of us fragile humans still smoke every day. Or the effects of drinking on your liver, drunk-driving, etc. - people celebrate that lifestyle with drunk selfies at parties & clubs, so (playing devil's advocate here, not endorsing it) why
not allow people be proud of their eating habits?
Also, there's an enormous amount of psychology that plays into food: food addiction, comfort food, emotional eating, availability & budget, dietary education, etc. I became overweight after high school because I didn't know squat about the realities of nutrition & truthfully didn't much care - I ate whatever I wanted, whenever I wanted, even if that meant a pair of double bacon cheeseburgers at midnight. I was fortunate to have a fast metabolism so that I never got much beyond 50 or 60 pounds overweight, which didn't look too terrible on me because I'm tall, so I never had to deal with getting made fun of or anything, but it still wasn't a super-healthy route for me to pursue.
Back then, to me, eating healthy meant bland salads or Jenny Craig programs, or having to go slave away at a gym, all of which were unappealing. It was eye-opening to learn that I could eat all of the delicious food I wanted and actually
lose weight by eating lean proteins like chicken, complex carbs like brown rice, good fats like avocado, etc. - which may sound bland, but with a little effort, you can whip up some mighty tasty meals. That doesn't mean that I eat perfectly all the time, but I've gotten a handle on my weight, my energy, and my blood tests, all of which has made a huge impact for the better on my quality of life.
I don't quite know how to describe it, but it's like your body is either a prison or a spaceship...you're either locked in & homebound & confined to doing low-energy activities, or you're free to pursue anything you want to, which includes sports activities, visiting new places, etc. & actually feeling good enough to enjoy them properly.
