This article makes me sad. No it’s not okay to be obese and it should be a crime to try to convince people otherwise. I know how hard it is to lose weight and it’s a huge task where you need to stay focused for a very long period of time, years probably depending on your goals and where you start at. There’s no shortcuts.
The issue you’re missing is that being obese makes you less productive human being in so many different ways and you are prone to sickness - latter alone makes you a huge liability to the society because we, the other people have to take care of you when you get sick.
By no means you need to look like a model, please don’t, but you should be healthy and I’m sorry but no matter how you try to convince yourself or others, being obese or fat is not healthy - it’s a simple scientific fact and not an opinion.
