At one time or another, it seems we’ve all had that friend.
The one who seems to be able to eat whatever he or she wants without gaining weight. And maybe, if we’re close enough,
we’ve expressed how lucky they are to be so “naturally thin.” But, does such a thing really exist?
A friend recently sent me a link to the following BBC documentary from 2009 titled, “Why Are Thin People Not Fat?,” which explored this question in some depth. In the film, a subject group of “naturally thin” folks were told to increase their calorie consumption and limit their exercise for a period of 4 weeks to see if they would gain weight as expected.
I won’t spoil the results for those of you who are interested in watching, but I will say some of them were quite interesting. It should also be noted that this experiment was done primarily for entertainment so I doubt it would hold up to rigorous scientific evaluation. Because of this, I think it’s only appropriate that we take the results with a grain of salt. Regardless, the exploration of genetic predisposition to weight is fascinating.
Here is the complete documentary on YouTube:
Do you know someone who fits the description of “naturally thin”? Are you one of these people? What do you think of the concept of a weight set point? If you did watch the documentary above, what did you think of it?
And most importantly, for all my British friends out there- what’s the deal with your fondness for eating pizza with mayonnaise?
