Inside each of us lives a bustling community of microbes; tiny organisms that outnumber our human cells. They’re there from the very moment we’re born, shaping our immune system and influencing our long-term health.
The science of the microbiome is evolving rapidly, but one thing is clear: We need to take care of these microbes so that they can take care of us.
Today, I’m joined by Dr. Suzanne Devkota and Tim Spector to explore h...

We often hear people talk about metabolism - whether it’s fast, slow, strong, or sluggish. It’s one of those health buzzwords that’s often said, but rarely understood.

In this episode, Shawn Stevenson and Tim Spector cut through the confusion....

Calories. They’ve been at the heart of dieting advice for decades. Eat fewer, burn more, lose weight. simple, right?
Except it’s not that simple. Calories only tell us a fraction of the story. To really understand what's going on, we need to take a step back and look at the bigger picture.
Helping us take this step is biologist Giles Yeo. He’ll explain why obsessing over the numbers doesn’t work, and how we can change the way we ...

Today we’re talking about something we’re all guilty of: food waste.
A forgotten yogurt at the back of the fridge, a stale hunk of bread, a bag of dry wilted greens.
They may seem insignificant on their own, but collectively, in every kitchen across the world they add up to a global environmental crisis.
So, can we change the way we approach food and help curb this epidemic of waste?

Conditions like endometriosis and polycystic ovarian syndrome are more common than might think. Yet they’re often misunderstood, frequently undiagnosed, and are all too easily dismissed.
That’s why it’s essential for us to build a clear understanding of these conditions: How lifestyle factors can influence them, and when it’s time to seek expert care.

You can think of your immune system as your body’s personal physician. Diligently working around the clock to monitor, detect, and repair anything that might disrupt your health.
