Mukbang Videos

If you dont know what they are take a minute and look them up on youtube :)

So, I'm oddly fascinated by these videos and now because of them im trying new foods I've never tried before. One thing I have noticed though are the portions are huuuge for just one person and the individual is literally shoveling spoon fulls into their mouths. Do you think these videos are harmlessly entertaining or could it possibly result I some kind of eating disorder or maybe even obesity?
