There's nothing awkward about it at all, nobody deserves to be bodyshamed, period. Yes, being overweight is unhealthy. The vast, vast majority of overweight people know this. The only thing you accomplish by expressing your concerns and "acknowledging it's bad" unprompted is making the person feel worse, they're not gonna go "Wow, li10 is concerned about my weight, this was the moment I was waiting for to start being healthier". This isn't a hallmark movie, it rarely works like that.

If an overweight person expresses a desire to lose weight and be healthier, absolutely encourage and support that... but support looks like things like offering to be a gym buddy,sharing healthy recipes, words of encouragement as they progress, maybe even joining them on their diet, etc... and even then only if they've expressed a desire for that support. Telling them unprompted "I'm concerned about your health due to your weight" is NOT support, it's nothing but an empty platitude.

No. I don’t think it’s awkward. At all.

The only person whose weight and body is your business is your own. My body isn’t your business. Your neighbor’s body isn’t your business. Your coworkers body isn’t your business. It’s not your business and your opinion doesn’t matter about any body but your own.

So how about this… let’s just not talk about each other’s bodies and let people be who and what they are. Fat people have enough shit to deal with already and they don’t need shit from you too, whether it’s ’support in losing weight’ or criticism.
