We all have that one friend who defies all laws of weight gain. The one who can down a cheese burst pizza with a glass of coke, portion of fries without ever having to buy bigger pants on a monthly basis. Or the guy who can guzzle as many beers as he wants and still doesn’t grow a beer belly.
So did these people just get lucky in the genetic lottery? Or is there such a thing as an inherited fast metabolism? And if so, does that mean the less fortunate ones with an ordinary metabolism are doomed to lifelong weight struggles?
The answer is a more complicated than a yes or a no. But, yes, a person’s metabolism (fast or slow) is something they’re born with. It also implies that even though your metabolism is in your DNA, it can be changed.
