These claims of yours have nothing backing them up, AutoModerator. Unless you can show a source for your 20% men get 80% women, it's just an opinion and that means jack shit.
I agree these percentages were just pulled out of his ass, but can I provide some anecdotal support that the ratios are at least skewed? First thing though, you're going to have to just trust that I'm pretty decent at judging what qualifies as 'overweight'. I've always had a knack for guessing things such as people's weights, ages, calories in various foods, and things of that nature. In addition, I know what qualifies as a healthy weight range for the typical person based on height and sex, and I also know the distinction between being overweight and obese. My guesswork is surely off the mark from time to time, especially in borderline cases, but I think I generally can tell when someone falls into a healthy or unhealthy weight range.
So on to my point. Roughly 72% of adults are overweight, and this is distributed about equally between sexes.
That only leaves 28% of men and 28% of women who are not overweight. For quite a long time now I've been paying attention to couples. It's probably my autistic side, but I keenly observe things like the couple's ages (is there a large disparity between ages?), their weights (again, is there a disparity?), if they are of different races (I'm not racist in any way, but it's something I notice), how they interact (do they seem to be chatty, do they joke around a lot, or are they being silent), disparity between classes, does one have a noticeably better personality than the other, facial attractiveness (is one more attractive than the other), etc. Some of these things can be hard to impossible to judge, like someone could seem to have a shitty personality because they failed an important test, or their dog died that day, but weight is pretty straightforward. Now, among everything I just mentioned, the things I notice foremost are facial attractiveness (which I won't talk about right now), and weight--specifically, dynamics where the female is apparently overweight and the guy is in apparent perfect shape, or vice versa.
The 'results' have been astonishing to me. It's an extremely rare occurrence to spot a perfectly in-shape female with an overweight guy. However, I see the opposite dynamic every singe day. I've seen thousands of couples where the female is overweight and the guy is in great shape.
Moreover, I have never seen an obese man with an in-shape woman. On the other hand, I see obese women with in-shape men every single day. According to the CDC about 40% of the adult population is obese, with women overtaking men by about 4%.
At the very least, this means men are willing to date a wider percentage of the female population, than women will men. At most, it suggests automod's claim has credibility to it. It suggests hypergamy, that is, women generally set a minimum standard (which is higher than their own status).
Especially making the assumption that women don't know what it feels like to not have dating options. You make it sound like they're some majestic animal that don't follow normal human behavior. Women are just people like you and me. Some get dick, others don't. Some may be into you and others might not. It's just life.
What world are you living in? I recommend you just open your eyes and look around sometime. There isn't a single shred of evidence that any women (apart from ultra deformed, disease-ridden, older women) struggle in the slightest to get a date or get laid. Now you're the one clearly pulling shit out of your ass. You can right now create a POF or OkCupid, and use 'Pig Lady's' profile (it's a humongous woman with a hairy chest and a hideous pig nose), and the messages will begin to surge. Unbelievably, these incoming messages will be from average looking dudes. All this without even having to send them messages first. A well above average guy could remain online for weeks and never get inboxed without first messaging a woman.
