Why should it be acceptable for men to look like this?

Biology student here- I'm pretty sure women naturally are supposed to have more fat than men (to protect fetuses) and after being pregnant are more likely to be overweight because some women's metabolisms slow down after they have kids (not sure why this is, but this was was case with my grandma).

And biologically, curvy women = greater fertility = should be more attractive to men for reproductive purposes. Curvy isn't equivalent to obese, though. The two are different things entirely. So the "curvy" argument doesn't work for guys (even though that's just a mocking picture).

You can't really shame either gender for weight, though, because people can have metabolic issues etc. that can affect their weight. I know OP is responding to an earlier thread but it needs to be said.

Could you explain the science behind this please, I'm interested

Girls have a higher BF threshold. I.e. you need to have over 30% BF if you're a girl to be considered obese (if we're classifying obesity by bf as opposed to bmi) whereas men with 25-26% BF are considered obese.

So I don't know what this argument is supposed to show.

Childbearing hips! Women with wider hips = less likely to have complications in childbirth.

Plus bigger boobs = tricking men into thinking they produce more milk (evolution up to it's old tricks again, obviously this isn't true but it's how women attracted men back in the day, and men selected for bigger bwabs in women as they were preferred)

I might be wrong, but I think the other poster was explaining the reasoning behind why women's obesity threshold is higher. Without their explanation, all you've done is give some fairly arbitrary numbers (albeit backed, presumably, by some kind of health authority).

Nah. It's might be, however, because women with larger breasts are smarter and hence could have been evolutionarily selected for survival reasons. http://nhne-pulse.org/study-women-with-large-breasts-are-smarter/

How could "evolution" trick anyone into doing anything? It is simply the process by which the most survivable reproduce the most. Larger breasts which were falsely associated with greater fertility would serve no survivability purpose and be deselected.

Well you know, that's what I was taught in lectures by one of the most prominent human evolution researchers in the country, but hey ho, of course I am wrong.

There are some complaints that it's not as easy for women to be "slim" because women have naturally higher BF%. Which is quite false as the threshold for what is considered "slim" (or average or w/e) is lower for females than for males (classifications take into account natural differences in BF).

But I am not sure what he meant exactly by his post, I only used his post to make a point which many people ignore (perhaps he doesn't disagree).

I actually think the guy on the left has a nice face, he does need to loose some weight for health reasons but he should be able to get a gf.

Clinical Sciences student here - your metabolism slows down as you age, it's normal for all genders. It really is up to people to make an effort.

Edited out!

Literally speechless.

My grandma's metabolism slowed only after she had children, though. Her husband didn't have to shift a pregnancy weight, since he wasn't the one carrying a child for nine months. Therefore, she weighed more than he did.

Yes but everyone's metabolism slows down. Her husband's metabolism slowed down too. There are other things to take into consideration as well. Was she at home taking care of the kids while he was working? Was he a bit more active than her?
