Chris turns to longevity doctor Peter Attia to find out how changing his eating habits can help his quest for longevity. Ironically, the answer is to eat no food at all for four long days. If he can bear the hunger, fasting will unlock his body’s own anti-aging powers and give Chris the edge he needs when he tries to hunt for his next meal … by spearfishing off the Great Barrier Reef.

Master Chef judge Gregg Wallace and mathematician Dr Hannah Fry take over a restaurant and invite five special guests to enjoy a dinner party with a difference, where they will be scored on the carbon footprint of every dish they choose. Food accounts for a third of all greenhouse gas emissions, so making informed choices about what we eat is more important than ever.
Gregg is with the kitchen team preparing delicious dishes and uncovering tips and tricks we can all use to cook more sustainably. Hannah is working with environmental scientists to reveal the carbon footprint of every single item on the menu and uncovering the latest research that can help us enjoy the food we love that doesn't cost the Earth.

In a late Jurassic forest in what is now China, an Epidexipteryx escapes from a juvenile Sinraptor by climbing a tree. It finds a beetle grub in the tree bark, being shown to use its elongated fingers in a similar way to a modern day aye-aye. However, its prey is stolen by another, larger Epidexipteryx, and after a brief bout of posturing, the smaller individual goes to find more food. It drops a second grub to the forest floor, where the other Epidexipteryx retrieves it, only to be killed by the juvenile Sinraptor. The episode then cuts to a desert in late Cretaceous Mongolia, where a Saurornithoides is shown brooding a nest of eggs. When it leaves the nest, an Oviraptor raids it, fleeing when the troodontid returns. The Saurornithoides is suddenly attacked and eaten by a Gigantoraptor, which then heads to compete in a breeding ritual for mates. The males use their feathers for display, a brief fight between two erupting at one point, allowing the females to choose the best suitor. The episode finally cuts to an early Cretaceous forest in China, where a Xianglong is being hunted by a Microraptor, which uses its feathers to pursue the gliding lizard in the air. A Sinornithosaurus attacks it, and after a brief chase the Microraptor manages a lucky escape. The Sinornithosaurus, alongside two other members of its species is then shown hunting a Jeholosaurus and its three young. The group brings down the parent, the narrator explaining that their possibly venomous bite allowed them to tackle animals much larger than themselves. A montage is then shown of the feathered dinosaurs featured in the programme, with the narrator saying that Microraptor not only hints at how flight might have developed, but also that dinosaurs still live amongst us today, as birds.

Upending the conventional wisdom of why we gain weight and how to lose it, Fed Up unearths a dirty secret of the American food industry—far more of us get sick from what we eat than anyone has previously realized. Filmmaker Stephanie Soechtig and TV journalist Katie Couric lead us through this potent exposé that uncovers why—despite media attention, the public’s fascination with appearance, and government policies to combat childhood obesity—generations of American children will now live shorter lives than their parents did.
