Not sure if it's already been posted as it's still a new video. But what do you think?

Looks like the same guys who did the video here:

Why we are fat - explained in one minute

I'll paste the accompanying text from gizmodo

"

Why can't you stop eating at the sight of delicious fatty or sugary food, even while your stomach is full? Answer: You have a good system in place to avoid over-eating, but it's overridden by your caveman instincts. Confused? Watch this video.

When your stomach is empty, it produces an hormone called ghrelin, which interacts with a neurotransmitter in your brain called NPY. This turns on your hunger. When the stomach is full, it produces another substance, called leptin. Leptin has the contrary effect, and NPY turns off hunger.

But there's something else: the sight of fatty and sweet food, high in energy, fires up a prehistoric instinct. Our ancestors were always on the prowl for food in a world where that food was hard to catch. They had to save every bit of power to survive and, while presented with the opportunity, eat and store it. Just like any other animal on Earth.

And here's where things get interesting: since this kind of food is everywhere, we indulge ourselves, entering a vicious circle that interferes with the ghrelin-leptin mechanism, turning us into fat people. Unless you exercise, that is.

So how to stop being so fat? It's not about starving yourself. It's just about eating healthy and exercising.

"

I get pissed off with these guys. I suspect it is because they are over-simplify the subject in order to make it comprehensible to all and in doing so people will take away the wrong message "I'm fat because of this uncontrollable science thingy and the environment".

It did lead to me reading a bunch of research on ghrelin which was cool but not many people take responsibility for their wellbeing etc etc. Something of a pet peeve :evil:

pretty sure this is the same guy from minute physics
