A 7 day challenge for fatties who simply "can't lose weight" Eat nothing for 7 days.  Take some vitamins, drink lots of water, but eat no food.  Simple and easy to do, not the most healthy thing in the world but better than being morbidly obese.  People much thinner than you have lived much longer without eating, you'll be fine.  If you fail to lose weight (5 pounds or more), then you need to get to a major research hospital as soon as possible because you are the proof that not everyone can lose weight. Of course this will never happen, but it's a way to get a fatty to actually try it. It's a win-win for fatties.  Either you prove that yes, your metabolism is fine and you can lose the weight or you prove once and for all that weight loss is impossible for you.  Every fatty should be chomping at the bit to do this and show society just how wrong they are...but nobody has.  Except that one guy who ate nothing for a year and surprise surprise, lost 300 pounds. This is what I'm going to start telling fatties who simply "can't lose weight".  Prove it.  I'm tired of the burden of proof being on me.  You think you actually only use 500 calories a day?  Fine, prove it.  Eat nothing for a week and show me you lost only one pound.  If that's true, then there's revolutionary medical data hidden in your body that should be analyzed.  So you either lose weight or you become famous as the person who proved all of us shitlords wrong.  There's no downside for you.
