Wasn't trying to be rude. My best friend had MI(myocardial infraction) at 27 and the doctors said he has to loose weight otherwise it can turn into a massive heart attack that can be fatal. But I just don't understand why people just prevent it when it's still early and he's not even that fat either.

It’s incredibly naive when people just assume overweight people had the forethought that they would get fat eventually. That’s not how it works. There are a ridiculous amount of reasons for people to gain weight and saying “well you should’ve prevented it” is fucking asinine and stupid. 100 pounds ago I was 16 years old, go tell a 16 year old to just hire a personal trainer. Hell, a year ago I couldn’t afford a personal trainer. Weight loss isn’t just a thing that happens, it’s really difficult for so many reasons. Not impossible, but a lot harder after years of neglect and obtaining bad habits. The mindset you and lots of other people have doesn’t help anything, it just makes you look ignorant and selfish.
