So the smaller the eating window, the greater the reduction in body weight. But there have been some studies that actually control the amount of calories that people eat. but have some people having it in a bigger eating window, some in a smaller eating window.
And what these studies have shown that if you have the same amount of calories, but you change the period in time in which you're eating your food, there is an additional benefit on metabolic health. There is a benefit in terms of blood lipids, in terms of inflammation, independent of calories.
Yes, but the bulk of the benefit is due to a reduction in calories. So there's some benefit independent to calorie restriction, but the bulk of the benefit that we see is due to a subconscious or unintentional reduction in calories. And I think this is when we're thinking about diets, I think we need to think about how easy is it to implement? Is there any evidence behind it? And 99% there isn't.
For the ones that there is evidence, like time-restricted eating, can we do it in a way that still enables us to live our life that's sustainable? And the sustainable point I think is really important because there's now some new evidence emerging around consistency and the importance of consistent eating patterns. And I think this is fascinating.
So there's research showing that if one day you're having three meals and then the next day you're having nine meals and the next day you're having six meals and the next day you're having four meals, that troubles your body. It's like, whoa, hold on, I'm used to having, you know, four eating events a day. And this is important to bear in mind when we think about snacking.
If you're typically a snacker, then fine, carry on snacking as long as it's on healthy food and as long as you have your last snack before nine at night. If you're not a snacker, having me just vouch for the great benefits of snacking, don't start snacking because you don't want to be inconsistent.
And this new evidence emerging around the consistency of eating, and there's some research done actually quite some time ago that started this idea, I think is really fascinating. So try and have a consistent eating pattern. Same applies to sleep. Try and go to bed at the same time, get up at the same time. We've done some work around social jet lag. I don't know if you've heard of that term.
So social jet lag is where you have an inconsistent sleeping pattern throughout the week. So for example, for many, maybe 20 year olds or students, they might go to bed at a sensible time in the week and go partying and crazy at the weekend. Or for someone like myself, I go to bed late at night because I'm late night working, parenting, etc. And then at the weekend, I catch up.
So if you have more than about a one and a half hour
uh increase or decrease in sleep between your work days or weekend days etc that's called social jet lag this is a bit like jet lag going from one country to the other and what we know is and we've published on this from our own zoe predict research people who experience social jet lag so have this inconsistent sleeping pattern make poorer dietary choices
they have more inflammation, they have a different gut microbiome composition. Now, it might be because of the dietary choices, but again, it just plays into this whole idea that we're talking about, that we can't just think about the food in isolation, we need to think about how we're eating, our lifestyle, etc.
Sorry, I'm having to laugh. This is like NutriBollocks beyond NutriBollocks, but please.
Okay, so seed oils I think is at the top of the Nutribollocks list. it blows my mind what you've just read me it seriously blows my mind i've done lots of research on seed oils so i can talk from my own research as well as all the evidence bases out there there is absolutely no evidence that is credible evidence when interpreted in the correct way to show seed oils are harmful what is a seed oil
So a seed oil is an oil from a seed. So the most common seed oils in the UK is rapeseed oil, which is also known as canola oil in the US and many other countries, followed by sunflower oil. The most common seed oils in the US are soybean oil, followed by rapeseed or canola oil, followed by sunflower seed oil.
And there's about three or four arguments that people use to say that Cedars are bad for us. And if you go on social media, I mean, this is a perfect example of night and day between scientific evidence and what's on social media. If you go on social media, Cedars are toxic. Cedars are going to give you Alzheimer's. Cedars are going to give you cancer. Cedars are going to kill you.
You look at the evidence, it's totally the reverse. Now, you can have sensible, boring scientists like me say, Seedles are really good for you. You could put that as one of your assets or whatever you call it, or adverts for this. So we could say, Seedles are really good for you, Stephen. Or I could tell you, Seedles are toxic. They're going to kill you. Everyone's trying to kill us with Seedles.
What's going to get more clicks?
And so the sensible science, there's no silver bullet. There's no like, you know, crazy inflammatory argument. The sensible science isn't going to get the clicks. So unfortunately, the voices of reason... And often it comes from boring academics like myself, not saying other academics are boring, but sensible academics like myself that give the, you know, the balance. We don't get a voice.
We're not being heard, which is one of the reasons that, you know, I wanted to come on this show because of the misinformation. And we have to get the voice of reason out there. We have to get the voice of reason. So things like that to do with CEDAWs are not what's dominating the headlines.
So what people say in terms of seed oils is, firstly, our intake of seed oils has increased 100-fold the last 20, 30, 40, 50 years. And with that increase in seed oil intake, so has cancer increased, so has cardiovascular disease increased, so has obesity increased, so has Alzheimer's, et cetera, et cetera. So it must be to do with the seed oils. Well, what else has changed in that 50 years?
