Presidents normally age badly during their presidency due to stress. Look at George Bush in 2000 and compare him to 2008. He looks like hell, ditto Obama.
Trump has barely any noticeable stuff happen. Whatever happened would have happened regardless to him just being 10 years older when he started campaigning in 2015. He thrives on the hate he receives.
Weight is one of those things that most people can largely change about themselves. I agree it's a lot harder to regulate your weight when you have conditions that reduce your mobility and make you burn far fewer calories like ME/CFS or fibromyalgia, but the basic principles of thermodynamics still apply.
Trump isn't one of those people with a debilitating condition other than his age. He's genuinely an unpleasant glutton who lives on a diet of Big Macs and Diet Coke.
Ehh fat people need to stop trying to hone in on the moral high ground of race, sexuality, and disability and just accept they are fat fucks because they eat like pigs and don't deserve special treatment. If you don't like it put down the hoho and eat some fucking kale.
It’s not that easy for everyone. People’s metabolism works in different ways and genetics is also a huge factor. I have a friend who eats roughly the same as me and regularly goes to the gym while I don’t, and still weighs like 40kg more.
Plus, even when metabolism isn’t the issue, a lot of those people have eating disorders and shaming them for that isn’t cool.
Telling people with eating disorders that everything's fine is even worse. Also, if your friend eats properly and works out they're not fat, they're heavy, noone is making fun of those. They might not let you into the club tomorrow.
