Chapter 1: What is the main topic discussed in this episode?
Hello and welcome to The Midpoint. And it is a very warm welcome back to the wonderful medical scientist and clinical nutritionist, Dr. Federica Amati. She's back with a timely new book, The Appetite Reset. And the core of the book is the idea that hunger is not a test of willpower. It is indeed a biological function.
And this, of course, comes out as the use of GLP-1s are ever more mainstream, ever more popular. And the conversation around their long-term use and how to get off them without piling on the weight is also getting louder. She looks at why jabs alone are not enough and why you should be preparing before you even start using them.
And of course, if you don't want to use a GLP-1, the book is for you because it aims to help you reduce food noise, something people talk about when they find it really difficult to lose weight and how you can improve that idea of being fully sated. There is lots to talk about. You've also sent in a load of brilliant questions, so I'm going to put those to her too.
So let's go meet Dr. Federica Amati. Federica Amati, it's so great to have you back on The Midpoint. And you have this new book, The Appetite Reset. And I'm intrigued to know when you realised this book was necessary with the conversation and the noise around GLP-1s.
Chapter 2: What is the core idea behind Dr. Fede Amati's book, The Appetite Reset?
Yeah, I think it was around autumn last year, actually, so quite recently. But the conversation had really picked up. I was asked to contribute to a documentary for the BBC two, three years ago when it first started. And a lot of the predictions we made then started coming true about... how people were going to come off it and potentially be in worse shape than when they started.
And all of these stories started to come up, you know, lean mass loss and side effects.
Chapter 3: How do GLP-1 medications change the conversation around weight loss?
And I just thought, actually, I have quite a lot of patients that I've looked after with my clinical team, Well-Founded Health. They're a group of doctors and we work together.
together and it's exactly how you should take these drugs right so with all the care and even then it's complicated and each patient's very different and so I just thought actually this is a you know I always try to make my books useful Gabby so that people can actually take something from them and improve their lives and I thought this would be quite useful because we know that the stat that did it for me was that 99% of people are accessing these drugs outside of a healthcare setting
99%?
Yeah, depending on which estimate. Some say over 95, but it's definitely sort of in the 90s.
So they're not getting any support before they go on them, during their usage, maybe ticking a box on a website or something, and then coming off, which is obviously hugely important. Exactly.
Yes, and now we know that 50 to 60% of people come off within a year. And this is for people whose prescriptions are due to obesity or type 2 diabetes. So this is for the people who are taking the drugs as intended.

Chapter 4: Why is it important to prepare before starting GLP-1 medications?
Even they're coming, sort of stopping within a year. So there's a real need to help support people through this time. And as I started writing the book, which was really designed to be a companion to anyone who is thinking about taking the drugs or on them or coming off them, I started to realize actually the science of appetite is fascinating.
And it's not always explained or taught, even at medical school. So as you know, I teach medical students about nutrition. And I was like, we don't actually teach that much about how appetite regulation works, the hormones involved, you know, how it all functions.
Chapter 5: What does 'food noise' mean and how can it affect weight loss?
So in the end, the first half of the book is actually just the physiology of hunger and appetite.
Which is wonderful. it's relevant to somebody who isn't going on GLP-1s or thinking of going on them because they can almost if they understand what appetite is and how it works you're hoping that they then can control that with their diet
Yes. The hope is that if we have a better understanding and appreciation of how the system is set up and it is actually set up for us to succeed, like biology is trying to help us out here, then we can appreciate it better, realise that we are in a situation where the environment we live in is stacked against us. But there's things we can do to help ourselves out of that.
And then also, if you're somebody who actually biologically needs more support, and so when you start to understand that in some people, the brain responds differently to the same signals, then the medication becomes a really good option. But we still need the support, the lifestyle medicine intervention alongside the medication. Otherwise, you're just getting half a prescription.
And it really isn't setting anyone up for success. So I'm hoping that the book will help more of us appreciate how amazing our appetite system is, how brilliant the biology inside us already is. And then also make sure we take these medicines seriously. Don't treat them as a silver bullet that works for everybody. They really don't. Right.
Like every other medicine, there's side effects and there's potential that it won't work.
If our body and our brain are set up to understand that appetite is something that you sate and then later in the day when you need to eat something, your brain, your body tells you, what happens to people who talk of food noise, who just don't seem to be able to control that appetite?
You know, so food noise is super interesting because it's essentially something that's a result of these medications is suddenly so many patients have described food noise quietening, switching off food noise, that there is now medical consensus as to what food noise is. Before these medications, it wasn't a thing, which I find fascinating.
So now there's, for the first time, literally last year, a group has published what's considered to be the first description of it and the first way that we can categorize food noise. So it's a really important point to say that food noise isn't just thinking about food or being a foodie. Food noise is disruptive. It gets in the way of your normal daily function.

Chapter 6: How can understanding appetite physiology improve eating habits?
It's not drooling. I think it's true. It's when you're, like, you... When you're just releasing your saliva. Yeah, there's a phrase for it. It'll come to me later. So that starts, like, increasing. And your pancreas gets primed to releasing insulin because we want to absorb the nutrients as efficiently as possible, right? So that all happens before you've taken your first bite.
Now, if you cut that out entirely and you're somebody who's drinking your lunch at your desk... Mm-hmm. you've just given yourself, you've just shortcut one of the main things that are part of the appetite.
So what's happening then? Say you are drinking your lunch at your desk.
If you're drinking your lunch at your desk, you don't have any of that priming. So what's happening to the nutrients? So the stomach hasn't increased its gastric juices, for example. So you're a bit less efficient at breaking the food down in your stomach. So some of it will just leave you without leaving the goodness. Yeah, it just won't.
You won't have the same amount of breakdown and the insulin priming won't have happened as well. So you won't start absorbing nutrients as quickly. It's all things that when you look at population level data, the populations who spend time preparing their foods and sharing it at a table have better health outcomes. They're associated with overall improvements in markers of health.
The Mediterranean diet, one of the key components of the Mediterranean diet is conviviality, which is this idea of preparing your meals and sharing them. It's literally a part of the diet. Because we know it's so important. So it's called the cephalic stage of appetite regulation. It's this interaction with food, seeing, smelling, and thinking about preparation. Then you get to eating it.
And when it reaches your stomach...
our stomach is like a balloon and as it stretches they're stretch receptors and those stretch receptors are nerves that literally travel through the vagus nerve to your brain and they tell your brain hey there's food in the stomach we've got we've got something here and that's what i would describe as fullness so when your stretch receptors are activated to a certain point your stomach is full and you get that it's temporary but it means you've got enough food in your stomach but it's temporary
Then as your stomach empties into your small intestine, you have some of these nutrient-sensing cells are there. And they're really important for telling the pancreas, get the insulin out, there's things coming. They're very sensitive to the protein, the fat, the carbohydrates. And they're the first time that you see this GRP1, PYY, GIP, these peptides that are satiating there.

Chapter 7: What role do nutrients play in appetite regulation?
So that's the whole grain. It hasn't been rolled out. And is barley gluten free? Barley isn't gluten-free. Buckwheat is. Quinoa is. Frica, I believe, is also gluten-free. So there are gluten-free grains you can get.
So you can just use those like you would use rice, effectively. Yes.
You can add them to stews, to soups. You can put them in stir-fries. It's the same way as you would rice. I would say that for texture reasons, quinoa is a hard swap for me. Because it's a very different texture. But barley and buckwheat for the gluten-free option work well. You can make a buckwheat risotto, for example. And it's just, you know, I'm passionate about the whole grains.
The other group of foods is whole fruits. Both whole grains and whole fruits have been quite demonized with the kind of fear of sugars, glucose. But actually, they have so much more to them than their starch, right? Yeah.
And we know from population level data that the dietary factors that are driving most deaths, that's a strong statement, but it's what the data shows, is a diet low in whole grains. By a country mile is the biggest one. And a diet low in whole fruits. So diet low in whole grains, diet low in whole fruits, diet low in nuts and seeds is up there at the top.
So fruits are controversial, aren't they? And actually, one of the questions that came through to you was about
smoothies yeah and so when you say whole fruits you mean eating the apple rather than juicing the apple yes so eating the apple eating the banana eating the kiwi keep the skin on it to as many things obviously not bananas but like kiwis and apples and pears keep the skin on um whole fruit kiwi skin Oh, I do, yeah.
But you know the golden kiwis, the skin's a bit less fluffy, so it's a bit less of an aggressive way to do it.
Like you're eating a brush. Yeah. Okay, so obviously bananas, you can't keep the skin on, but any fruit that you can.
