Why Do Some Women Naturally Have Bigger Booties Than Others?

It's true - some women just have bigger booties without doing much to achieve them.

In fact some just go as far as sitting on them only - yet they remain so round and plump!

And some races, particularly the Brazilians, are blessed with larger derrières on average compared to some other races.

So why is that?

Brazilian Booty - Why Your Buttocks May Be Bigger Or Smaller 

Obviously the first way in which women can get bigger is by squatting, but some are just born with it. 

For instance, women in brazil are prone to be born with larger buttocks independent of trips to the squat rack, due to a mutated gene called "callipyge" (1).

Callipyge translates to "beautiful buttocks" in Greek, and one with more of it has a larger bottom with little fat.

And in sheep, this gene enables them to convert food into muscle 30% more efficiently than the other sheep (1).

Talk about an unfair advantage!

Also, women tend to store more fat in their buttocks and therefore have larger bums than men, as a babies brain relies on this for formation during pregnancy.

Steatopygia

Steatopygia is the term used for people who have a substantial level of tissue on their buttocks and thighs (2).

This obviously describes a lot of African women, as it's believed this is where it stemmed from.

Given the Brazilian race is made up (partly) of Black African slaves, it certainly makes a lot of historial sense (3).

Steatopygia is believed to have stemmed from two things:

1. All the walking around which generates a larger gluteus maximus due to the constant contractions

2. Stored fat in the thighs and buttocks for long periods to ensure survival, given hunting and gathering doesn't mean breakfast lunch and dinner like we enjoy today!

We're also told that The Khoisan population (from southern Africa) saw steatopygia as a sign of beauty and men were more sexually attracted to those women with it, in comparison to those without.

And it's fair to say given how many of you read and looked at my recent artice on the Brazilian Miss Bum Bum booty competition - not much has changed!

Factor that in with the love of the booty in today's pop culture, and we have a fair hypothesis to say that whilst time goes on, human beings don't change as much as some people may think.

So if you've ever wondered why some women naturally have bigger butts -  now you know!
