Frankly, I am not part of the "skinny" Somali male club but I wonder why my Somali brothers are so skinny when our diet consists of predominantly high carb food.
So true coupled with their lifestyle they probably walked a lot. And had an active lifestyle.The western diet is not suitable for Somalis which is why you'll mostly find fat Somali women and skinny Somali men. If we can make the right diet for our people then we can grow a healthy and strong population which could help some Somalis to gain desirable heritable characteristics.
During pre-colonial Somalia, the men back then looked much bigger, muscular and well fed.
The women looked slim.
