How to know if you're just unnatractive or fat?

Genuinely I'm pretty depressed about this because I don't know if I'm just fat or unnatractive

For extra detail I'm 103kg and 5'11 so there is not that many fat I lost around 5kg in 2 month so I'm working on it, but I'm curious how you can tell if you're just unnatractive or fat

I really want to escape this self images problem but it's hard if you are just turnturn out to be unnatractive (no I don't want personality bullshit​ we know it was a lie)
