On principle op you are right. But you'll always get flamed here for daring to say people are unhealthy and fat.
I am overweight for my height a bit. Got no excuse, not ill or anything, I just reduced my exercise without decreasing the food intake. And most of that is rubbish. I am trying to reduce, but it's not going anywhere fast. Being lazy doesn't help, but I do exercise every day, just need to do more.
People have lost sight of what healthy is, even if they won't admit it. It's like in the film wall-e, everyone becomes huge and floats around in chairs, it's totally normal to them. That seems insane for us, and yet we are heading in that direction. We are getting bigger, and sitting down a lot more. Less physical jobs, more sitting behind desks.
Saw an article recently about a girl who does horse riding, owns her own horse and had for years, and hadn't noticed her weight creeping up and up, until her horse went lame. Her vet pointed out she was actually too heavy for the horse, which had injured the horse. She wasn't even that heavy, but the horse couldn't handle it. She lost weight to keep riding and avoid damaging the horse further.
Too many people use excuses for why they can't lose weight. My aunt is a great example of that. Bad back, bad knees, bad hips etc. Wouldn't have happened if she hadn't deliberately gained weight to go on sickness benefits for the past couple of decades (sadly I am not even joking). And all her issues could be solved by walking each day and gradually increasing it. But then she would have to work again so she won't. A lot of issues can be helped with exercise and a lot can't.
But there's no need to shame either side for being thin or fat. Shaming people for being thin is really just as petty and sad as shaming people for being fat. We fight our own battles in our bodies, leave each other to it.
