DIGESTION
What happens to food after you eat it?
It goes in one end and out the other. The 7-meter journey in between is where all the actual work happens.
THE BODY
What actually
happens
inside me?
Digestion, metabolism, hormones, hunger, energy — let's look at what your body is actually doing behind the scenes.
THE IDEA
Your body isn't a machine with a simple instruction manual.
We often talk about the body as if everything has one cause and one solution. Eat this. Avoid that. Boost this hormone.
But underneath all of it is a huge network of cells, organs, hormones and signals constantly responding to what is happening around you.

APPETITE
Why do we get hungry?
Hunger isn't just an empty stomach. So what actually tells your brain that it's time to eat?
GUT MICROBIOME
The gut microbiome: you are not alone in your body.
Trillions of microbes, a second genome's worth of genes, and a lot more influence on digestion than most people realise — here's what's real and what's wellness marketing.
BODY FAT
What happens to body fat when you lose weight?
Not sweat. Not muscle. Not magic. Here's where it actually goes — and most people, including most doctors, get it wrong.
