What is the main topic discussed in this episode?
Calorie counting just doesn't work. We've been brainwashed for the last 40 years into thinking that calories were the thing. When you look at the actual data of all the studies done, 80 or 90 percent have returned to their baseline weight and then they tend to overshoot.
Dr. Tim Spector is the founder of the UK's largest twin study and the co-founder of Zoe, a personalized nutrition company. This episode deep dives on how gut microbiome determines our individual response to food and why shifting focus from calorie counting to food quality is the real key to long-term health.
70 to 80% of people believe that if they see high protein in a product, it's healthy. Only 10% of people need more protein, whereas 95% of people need more fiber.
If something is labeled organic, is that something that we should take seriously or is that just hype?
The certification of organic in the U.S. is pretty poor. And you might end up paying twice as much for something that says organic. There are lots of exceptions, but food companies deliberately make food softer and faster to eat. They want you to absorb it without noticing in front of the TV. We all know that feeling where it's a big bag of Doritos or Pringles or whatever it is. They've got exactly that formula.
What did twin studies reveal about why identical people respond differently to the same foods?
We're reading the back of a package and looking at the ingredient list. Like, what are some red flags to show, okay, this is ultra processed?
If you had to look at one thing on there, even if it says low fat on the front, that's a pretty good red flag because... Tim, welcome to Young and Profiting Podcast. Great to be here.
I am very excited for this interview. I can't wait to learn all about gut health and the types of foods we should be eating. And when I was studying you, one of the things that I found really interesting is that you've done an extensive amount of studies on twins. You actually started something called Twins UK. And based on that, you realize that genetics aren't the major factor when it comes to what we eat and how it impacts us, and that different foods can actually impact people with the same genetics differently, which I just thought was so mind-blowing. Can you explain to us some of the studies and research that you've uncovered via twins that helped you understand how food really impacts our bodies?
It's taken me 30 years to get to this point. So it wasn't overnight. And I was a very keen geneticist, thinking that everything was genetic. And so a big proponent of that. And it took really one experiment to change my mind, which was looking at identical twins who were raised together and really lived together until they were in their 20s, and looking at their gut microbes and seeing that when you looked in detail and you sequenced their gut microbes, the species they had were really very different. They only shared a small fraction of all those species and even less of the subspecies. And that was the first time in about 20 odd years that I'd seen anything really different in identical twins. Generally, they matched because they either had the same environment or they have the same genes.
There wasn't this rather randomness of finding these microbes. So for me, that was a big turning point in my career as a researcher and got me moving away from genetics. which I thought was the magic bullet for everything, into this new field, this is about 15 years ago, of the microbiome and gut health. Because for me, it was perhaps this missing link between what we've misunderstood about food, thinking that everyone who eats the same food reacts the same way. And suddenly you realize, well, if identical twins have different microbes, then they, in a way, react with food differently. That could explain why they die of different conditions, why one gets ill, the other one doesn't, et cetera, et cetera.
So that really fascinated me is this extra bit of individuality we've all got that you can see clearly in these identical twins that's quite difficult to see in the general population.
I don't think our listeners truly understand what microbiome means.
