Many people think that obesity kills more than malnutrition… But the truth is that both can be equally deadly.

Now imagine a body with no fat.
Nothing under the skin. Nothing between the organs.
Just bones, muscles, and emptiness.

In this video, we explore the science behind living without body fat:
what functions fat actually performs,
what would happen to your body if you eliminated it completely,
and why you couldn't survive even a few days without it.

We analyze the physiological, hormonal, and neurological effects
of having 0% body fat, from metabolism to organ failure.

And we'll also see real-life cases of people who pushed their bodies to the limit…
and what that cost them.
