Girls usually want the guy that's tall and strong. There’s no big secret as to why big, handsome alpha males get all the girls. However, there are instances where the guy is able to beat the system.
I'll share mine:
When I was in Latin America a couple years ago I stayed at a penthouse with a couple other guys. One of them, Kyle (I forgot his name so I'm using that one) didn't have a hard time dating down there. He was 5'5'', in his late 30s, bald, 50 pounds overweight, didn't own a suit, and worked as a teacher (Connecticut IIRC). I don't think he had IG but he apparently got his dates from Tinder. He has admitted to paying for sex on occasion. I never asked him but I wouldn't be surprised if he had a hard time dating in America so that's why he dates girls overseas. He told me he had 14+ day streaks where he would bang a girl (ugly or not). He would also get some stunners every now and then.
What worked for him:
Even with a teacher's salary most guys don't make that much in Latin American countries. Kyle would tell me if he wanted to especially meet up with a girl he would offer to fly her out to where he's staying if she was on the other side of the country.
He showed me his Tinder account, I saw that he had professionally edited pictures where he was in multiple countries (scarce resources).
He's pretty open minded. Like I mentioned before, he has admitted to paying for sex, he also was into drugs lilke shrooms.
If Kyle wanted to settle down he's be doing it out of abundance and not because he is dying for female attention. Also, nobody is aspiring to be Kyle, ideally get your income streams going when you're young and if you're overweight lose weight.
