A series of recent studies has shown that pudgy guys have a better immune system than thin guys. That's the good news. But, as it turns out, women seem to be more attracted to thinner men regardless how masculine their looks. The study was just among Latvian women, but, maybe it explains a lot.
The "Metro-Sexual" look is what gets the gals, but once married they feed you like a prize hog until you are neither attractive to other women nor likely to suffer the weaker immune system of your former thin self.
So for you single guys out there, drink your water, jog your knees sore, remove your body hair, dress from an Abercrombie catalog and get the gal of your dreams.
And for you married guys, well, bottoms up your beer boys, and eat more pizza.
