Eat less, move more. That’s been the mantra of the weight loss movement for decades. But as those who have fought the battle of the bulge will tell you, there’s a lot more to obesity than just too much junk food or too little willpower. Even when genes are taken into account, scientists have struggled to explain why one person can eat cake and stay skinny, while another munches on carrots and can’t shed a pound.
Now, exciting new research reveals there is a missing piece to the obesity puzzle, one that is highly complex and intensely personal: gut microbes.
Inside our intestines, there’s an entire ecosystem – our own “inner rainforest” - made up of microorganisms so small that millions could fit into the eye of a needle. But these tiny bugs that live in our gut are proving key to human health and the obesity epidemic.
Could microbes be the missing key to weight loss?
Some of these bacteria are nasty pathogens that lead to diseases. As a result, conventional wisdom has given all bacteria a bad rap – until recently, when researchers began proving what one science writer calls a “subversive” idea: bacteria are actually our biggest allies. By targeting them as the enemy, we’ve damaged our bodies’ own biological systems, including weight control.
Microbes help us digest food, harvest calories, provide us with energy, produce crucial vitamins, regulate appetite, protect our immune system and fend off the bad guys. But because of our modern lifestyle, including a highly processed Western diet and overuse of antibiotics, some of the species of bacteria that once lived in our gut are on the verge of extinction.
Our microbes need to eat, but we’re starving them by failing to nourish them with the proper foods. The result? Unhealthy guts, and an obesity rate that has skyrocketed.

According to geneticist Tim Spector, author of the new book “The Diet Myth: The Real Science Behind What We Eat”, the most important diet myth is that, “like identical lab rats”, we all respond to food and consume calories the same way.
But just like a fingerprint, each person’s microbiome is unique, and so is the way diet impacts our weight and our health. So the diet that works for a British scientist may be radically different from a hunter-gatherer in Tanzania, or even the person living next door.
In It Takes Guts we’ll explore the links between microbes, diet and weight. We’ll discover surprising new information about the food we eat, and the food our microbes love to munch on. And we’ll meet the researchers who are applying what they’ve learned in the lab to their everyday lives, and experimenting on themselves, including:
- an anthropologist who is on the hunt for gut bugs and performs a risky procedure with a turkey baster
- a microbiologist who feeds an artificial intestine called Robogut
- a student who eats nothing but burgers and fries in a “gut-wrenching” experiment a la Supersize Me
- a scientist who keeps all of his daughter’s diapers in the freezer
- a geneticist who has redesigned his family’s meals
With the help of colourful graphic animations, we’ll learn how we’ve damaged our microbiomes, and discover ways to restore our “inner rainforest”. As one researcher notes, “You never eat alone. Because whatever food you put in you're feeding trillions of your microbes.”
In the battle of the bulge, should we learn to trust our gut?

THE BOTTOM LINE IS STAY OFF A FAST FOOD DIET, AND JUNK FOODS WITH JUNK DESERTS, JUNK DRINKS; AND ANTIBIOTICS THAT TOO MANY CHILDREN GET TOO MANY TIMES AS THEY GROW; EAT MORE FIBRE FOODS..... FRUITS AND VEGETABLES, WITH AS NATURAL AS POSSIBLE PROTEINS [FISH, CHEESE, EGGS, BEEF ETC.].
