Functional Nutrition vs. Dieting: What Actually Works, with Andrea Nakayama
27 Oct 2025 · 25 min
Andrea Nakayama explains functional nutrition as a personalized approach that looks for root causes rather than following one-size-fits-all diets. She outlines three core principles: fat, fiber, and protein at every meal; eating the rainbow; and building a yes/no/maybe food list. Sleep, bowel health, blood-sugar balance, and a sense of purpose all connect to preventing neurodegeneration.
Chapters
We live in a culture, especially for women, where we're constantly looking for the diet, the whey, the thing that works, and we really attach to different trends, fads that might be happening. Low fat, high fat, high protein, low protein. And if you even look at the research around intermittent fasting, ketogenic, it's mixed. And even in longevity research, it's mixed. So we have to recognize that the answers may be more broad than narrow in terms of what we are subscribing to when we're thinking about food for ourselves.

Hold on to your hats.
Hello and welcome to this episode of the Feel Freaking Amazing podcast. I'm Wendy Trubo. Your host Ed Levitan is obviously not here today and we have an amazing guest. As always, I am delighted to introduce Andrea Nakayama. She is the host of the 15 Minute Matrix podcast as well as the founder of Functional Nutrition Alliance. She's leading thousands of students and practitioners around the globe in a revolution to offer better solutions to the growing chronic illness epidemic. And it really is an epidemic. By highlighting the importance of systems biology, root cause methodology, and therapeutic partnership, she helps historically underserved individuals reclaim ownership of their health. Andrea, welcome. I'm delighted to talk about this. This is near and dear to my heart.
I know it is. Thank you for having me, Wendy. I'm excited to be with you.
So tell me about what functional nutrition is like when you say it. Let's make sure we're using the same language. What do you mean when you say that?
I just love that you asked me that because I think it's really gotten quite far away. Functional medicine and functional nutrition from its roots. And I really am a person who upholds the foundations of the functional medicine model and then translates them to nutrition. So there are three primary tenets of a truly functional practice. That's a therapeutic partnership, meaning both people in the room come with their expertise. The patient has an expertise in themselves that the provider could never have. And we're making room for that deep understanding. So therapeutic partnership, looking for the root causes. And I always like to make sure I'm underlying that s in the plural sense. We're talking about multifactorial issues, not a Singular factor that we're searching for to bring everything into resolution and circumstances. Systems based approach. So that includes systems biology. The gut's connected to the brain, the hormones are connected to the liver, which is connected to the gut. Understanding that everything in the body is connected, but also using systems and frameworks to help us approach the complex challenges that we might experience in health, in our own health or in the health of the people we're serving. So three tenants, therapeutic partnership looking for the roots and a systems based approach. And then the difference that I'm bringing in in functional nutrition versus functional medicine, or I should say in addition to, because they work beautifully together, is really double clicking on the lifestyle factors, filling in those gaps beyond a protocol or a handout, really understanding the individual and their needs in relation to their body, to making dietary changes to foods. A lot of times we're still in a model of this condition means you do this diet. And in functional nutrition, we do not subscribe to any one dietary theory or lifestyle theory. We are really bringing in the slowed down process of seeing the individual. And I think that foundation is very unique to all of us. And we live in a culture, especially for women, where we're constantly looking for the diet, the whey, the thing that works, you know, and we, we really attach to different areas or trends, fads that might be happening. I'm going to be 59 next month. I've watched things go through every permutation of, you know, low fat, high fat, high protein, low protein. And if you even look at the research around intermittent fasting, ketogenic, like it's mixed. And even in longevity research, it's mixed, like there's different information that's still coming out. So we have to recognize that the answers may be more broad than narrow in terms of what we are subscribing to when we're thinking about food for ourselves. And so I really like to get people out of thinking about the healing diets, which are there for a reason and should be done with a provider. If you're on a healing diet that is very restricted, it should be done for a limited time because you still start to introduce nutrient deficiencies when you limit your dietary intake. So our three dietary principles, one I mentioned already, it's fat fiber protein at every meal or snack. Start there before you start measuring your blood sugar or worrying, like just fat fiber protein at every meal or snack. If you don't know like what's a good fat, there's plenty of information about that. Right. And I have it on my Website, I'm sure you have tools and resources, but like that's the place to start. So we're thinking more broadly. Second place I like to go is to eat the rainbow. And that way we're getting a lot of the phytonutrients that we need. They have so many benefits, anti inflammatory, help with our oxidative stress, all the things, the neurodegeneration, brain health. They also give us a lot of fiber, so they bring in a lot of nutrients. When we're thinking more broadly about color and we're getting super playful. The third principle that I like to bring to the table, so to speak, is what I call the yes, no, maybe list. And this is a great way to set ourselves up for the conversations with our providers who are starting us with those foundations because we're coming in saying, I can eat this and feel great. I am not, I cannot eat this. And I'm not sure, I'm not sure about this. That's a great starting place because like you, Wendy, I'm sure you've seen in the different populations that you serve, there's some people who are like, I'm in all the, I'm in pain all the time, but it's not my food. So they haven't yet made associations that are going to support them. And on the flip side of that, there's people who are eating three foods and they're coming in saying I'm not better. And they've developed a kind of conditions, food hypersensitivity, where they're noticing that there's a symptom or a sign that emerges every time they eat and they haven't done the internal healing and there's everything in between. So in our practice we've seen the people who are making, making no associations and the people who have limited so far down that they're now so malnourished that their body cannot heal in that state. So I just like to make it a little broader, I think when we are stuck in that sympathetic dominant fight or flight, what's the right diet, the right wearable, the right test, the right supplement, the right doctor, I call it pill protocol, practitioner shopping. When we're stuck there, we cannot heal. And so my goal is always, yeah, I can talk to you about the narrow diets, but is there a place where we need to broaden and heal the internal terrain in order for what we eat to be as vast as possible for that period of time, that season of your life and what you're going through as possible? That's always my goal.
No, that's great. Variety. Variety is key.
Yes. Thousand percent.
You know, you just highlighted something that was so like, the core tenet of med school for me was there's only one big problem. Find it, fix it. And it always sat funny. Like, there's often lots of issues going on. And sure, we can take away one thing, but I forget the guy who said, you know, if you're sitting on a tack, no amount of Motrin in the world is gonna help. And if you're sitting on 10 tacks, taking one away is not gon to help. You really have to shift the whole system so that you take away a majority of them until you can notice an improvement. So if I could pinpoint one failing in the medical system, it's that there's one problem, right? Like, one problem. No, there's usually a number of problems, and we have to deal with all of them.
Yeah, and I think that's such a good point, Wendy and I call it the X for Y. And it's also become kind of an issue in functional medicine as well, where people are sitting stuck looking for the test that's going to tell them the one thing. And this multifactorial piece and understanding that it could be from our life or our history could be an epigenetic factor. And the one thing I wanted to add there that helps us understand the difference of functional nutrition and functional medicine is I call it a three roots, many branches approach. So the branches are the signs, the symptoms, the diagnosis. And in medicine, and as patients, we often get stuck only thinking about the branch. This is the sign I have, this is the symptom I have, this is the diagnosis I have. What do I do? In functional nutrition, we not only recognize that there are three roots always when we're dealing with chronic issues, but our focus is the soil those roots live in. So the epigenetic factors, the omic factors, the procedures, decision factors, really understanding how we address genes, digestion and inflammation from a broader perspective versus a narrow perspective. So we tend to look at. And the way I teach is really a deep, deep, deep look at a timeline and a matrix that I've adapted from the tools of the Institute for Functional Medicine. So I tend not to lead with all these are the symptoms that means this. I'm usually looking at it through the lens of here are all the signs, symptoms, and diagnoses. They could be joint pain, fatigue, brain fog, so many different things that could also be conflated with hormone issues, menopause, perimenopause other inflammatory issues that aren't autoimmune. Like, there's so many things that can be going on. So I'm taking that opportunity to think about the entire pigment picture on my version of what we call the matrix. And it's aligned with some of your thinking that I've heard you speak into. I call it the story, the soup, and the skill. And so when we're talking about symptoms in isolation, they exist in the soup of the body, what's happening physiologically? But I also want to understand the scale. Where are you now? What are you doing? Are there easy changes that we can make? But the story for me is a huge missing piece. Piece that has a foundation in the expression of those signs, symptoms, and diagnoses. So for the work I do, it is a bit reductionistic to just look at the signs and symptoms from the approach that we take.
Yeah, that's fair. That's fair. So are you a fan of tracking? You know, because I'm a huge fan, I'll just acknowledge I'm a huge fan of tracking. I wear a whoop. I just upgraded. Cause I was like, oh, I'll do an EKG on myself and then I don't have to go to my doctor's appointment. By the way, don't do what your doctor does. Go to your doctor. Are you a fan of tracking for women, tracking their data to understand their health more?
I do. I love data tracking. I think sometimes we don't understand the data and we're making assumptions about the data without that full understanding. So I do think I love data, but I love quantitative and qualitative data both. And I think once there are times where we get too connected to the quantitative data without understanding the qualitative nuance. So I'll just give you an example of what I mean by that. There's definitely a trend of wearing a continuous glucose monitor. I think there's a time and a place for a continuous glucose monitor. Love all the tools and the tricks, but there are ways in which they're being misused and leading to confused narratives. So, for instance, somebody could be wearing a continuous glucose monitor, start to tell themselves a story about a food they ate because of a spike they're seeing, when in fact they didn't sleep last night. They worked out really heavy the night before, they didn't hydrate appropriately. It's not for their body. It's not just one thing. Our food doesn't exist in isolation. And I worry sometimes that we are becoming very reductionistic about the data we're capturing. So I love tracking. Sometimes the tracking we need to do is very simple just to get a sense of the more gross arena that we're living in versus the fine tuning of the data.
Yeah, I would say if you notice something like that, like, you eat something and your blood sugar spikes, then my response is, okay, wait a few days, test it again. If you have the same result, then you can say, okay, yeah, I am not reacting well to this food. But eating it in the same order matters, right? Like, if. So, yeah, I tested out. I wore CGM for a month. I can't say I wore it for a month because I got an allergic reaction both times. So I wore it twice over the span of a month for 10 days each. That's more accurate. And I found pretty consistently that every time I ate chickpeas, I went, like, through the roof. Didn't seem to matter what order it was in. And I was like, okay, I guess that's real.
Yes.
But I also found that order mattered a lot. And that was the takeaway that I took, was like, eat for me. Eat protein first, leafy vegetables, carbs last. Because I actually had it on on my birthday last year or a year ago, year and a half ago. And I didn't feel well. It was kind of weird. I didn't feel well. So I had. This is a really weird meal. I had Manchego cheese pox. Like, crispy. They were like Parmesan pox, but we made them from Manchego sheep cheese. And then I put chopped liver on top of it. And that was what I ate for dinner. It was really a weird dinner. I didn't feel well. I wasn't hungry. And then I had cake because it was my birthday and my blood sugar went nowhere, which was so shocking to me. I was like, I just ate cake. Why is it not spiking? And I just. That was really, for me, like, right in my face of. Okay, I understand order. You know, order matters for. And generally, I would say eat your vegetables and your protein first, and then eat your carbs and your sugar. If you're going to eat your sugar, try not to eat your sugar, but eat it later.
Yeah. And two things in response to that. I mean, I don't subscribe to any one dietary theory, but one of our food principles is fat, fiber, protein at every meal. And then it might be figuring out, like, what is that order? When I used to, early in my career, when my son was young and I would go into the classroom and teach the kids, I would teach them about a slow train and a fast train. And what you're talking about there are the slow train and the fast train. The fast train can't go any faster than the slow train in front of it. So if you have your protein and fat and fiber before you have your carbs, then you're going to have a slow train in front of the fast train and you're mitigating the spikes that you might have from fast train first or in isolation.
That's a nice way to think about it, actually. That's really like a clear methodology. So. So you've separately offline referred to challenges of having a chronic illness while in midlife. But I think bigger than that is I consider women to be underserved. And I didn't ask you when you said historically underserved in your bio, are you talking about women or are you talking about what's traditional underserved populations?
Yeah, I'm definitely talking about women and I'm talking about people with chronic health challenges. So I see those who are experiencing chronic health issues as underserved because our, as you know, our conventional medical model is better serving those with acute situations and is applying acute care model to those who have chronic health challenges. So women tend to, I think of it as the 80, 20, Wendy. Like, you know, 20% of people aren't going to get better with the all the hacks that are out there for us. And as we age, that 80, 20 flips because of so many issues that we experience as we age, as our hormones shift, as our immune system is compromised. So the 20% that doesn't get served is now the 80% as we age.
So how does the functional nutrition work with and prevent and slow down neurodegeneration and dementia and Alzheimer's and other degenerative diseases? Like, what's the relationship?
Yeah, I love that you ask that. And it goes back to a thought bubble I had earlier when you were talking about the tax. Right. So Dr. Dale Bredesen, who is one of the foremost researchers in neurodegeneration and very popular in the functional medicine space, has a model called the 36 holes in the roof. It speaks to that multifactorial approach. And what he's done is really map the physiological pathway for each of those potential 36 holes. And somebody who's experiencing neurodegeneration has at least half of those presenting in some way. When you look at those, and I have an article about this on the Functional Nutritional alliance website, when you look at those pathways and get down to the, you know, what is it, why is it happening? But what do you do now? Most of it, a lot of it is related to dietary and lifestyle modification. And so we can embrace that understanding from the researchers, from the medical doctors, but understand in functional nutrition, at least the way I teach it, the physiological mechanisms that allow us to make a difference in long term results. Again, if I think about it as the three roots and that soil that those roots live in, and the many branches, Alzheimer's, neurodegeneration, brain fog, any issues that we're having at the neurological level are the branches, they're the expression. And if we get down into that soil, we start to shift the expression of those branches, just like the medical doctor is shifting the expression of those branches in a more head on, targeted way. So they work together to say we're coming at the same issue from different vantage points. And it's a huge difference. I mean, sleep, poop, blood sugar balance, which are my non negotiable trifecta, are all going to be helpful in the prevention of neurodegeneration. Right.
And you refer at some point that I was looking at that having a sense of purpose. So our business is called Five Journeys because there's five intertwined, unique journeys, but each of them is a core pillar of your health. So your physical body, bones, muscles, ligaments, posture, movement, chemistry, that's the functional medicine, the emotional component, which is your relationship to yourself, your self, talk, the thoughts you have about yourself. Then the social component, which is you in the world, in community, and your spiritual component, which is having a sense of purpose, understanding what your legacy is about. So can you talk a little about why having a sense of purpose helps cognitive decline?
Yeah, I think that's a really great question and a great call out. And I love the pillars that you have in those different areas. It really relates to the matrix and there's a lot of beautiful overlap there. My work has really led me, and I'm going to just back up a minute to talk about narrative medicine, because when I mentioned the story, the soup and the, the skill, there's a piece of our story, who we are, what led us here, what really sparks us and moves us forward, where we're moved, where we feel a sense of belonging, all of those things have a physiological impact. As an example, there's been a lot of research around loneliness and the impact of loneliness on physiological health, on the chemistry. Right. But if we, if we flip that and we think about the power of belonging, when we belong, we are actually turning off inflammatory Genes at a rate that we can speak about. Turmeric or curcumin. Right. There's things we can do in life that actually have a physiological impact. And purpose is a huge one. I've been doing a deep dive into the science of longevity. I'm leading a book club where I've been reading a book every two weeks. There's a lot of science, a lot of technology, but without the purpose, without the reason why we're doing the thing, without the thing that fuels us to move forward, it's all for naught. And so purpose at so many levels helps us connect with ourselves. It helps us to resonate internally. It drives us forward to make change. But it also often helps us to feel connected to something larger than ourselves. Ourselves, which has a physiological impact in and of itself.
Yeah, it's funny, I got married a long time ago. I just actually celebrated my 22 year anniversary over the weekend. And one of my relatives was very overweight and for our wedding lost like a hundred pounds, which is a feat unto itself. And these are the days before Ozempic. She did this like work, you know, food and some movement, but she did it for my wedding. And after my wedding, there was no greater purpose. There was no reason to keep the weight off. There was no why. Like Simon Sinek, start with why. There was no why. And she gained all the weight back. And it was. It broke my heart. I was like, you know that you can lose it and you know that you can feel good in your body, right? It's not about. It's always about the weight. It's never about the weight.
Right.
So I was like. Because the way the weight is for her, it was mostly in her legs and her lower body. She had a really hard time moving. And when she lost the weight, she was more mobile. So it's so poignant to me that the why is always gonna override the what and the how. And really the why is the reason. Okay, tell me how people can find you. You.
Thank you for asking. Yeah, you can always find me at Andrea Nakayama on all the places on the web. Andreanakayama.com Andrea Nakayama on LinkedIn or Instagram. And that will lead you back to the Functional Nutrition Alliance. So there's two different bodies of work there. The Functional Nutritional alliance is where we train practitioners. And in the Andrea Nakayama space, talking a little bit more about longevity and narrative medicine and the intersections with functional nutrition.
This is fantastic. Thank you.
Yes.
You know, I think you can't get away from chronic illness. And you can't get away from health without taking into account the things that you're talking about. Right. These foundational impacts on our health. So thank you for this. Okay. This is good. So for the listeners, this is Andrea Nakayama. I'm Wendy Trubo. Thank you for joining us for another episode. And, Andrea, thank you for being here and sharing this cause. I think this will make a difference for me, people.
Thank you so much, Wendy.
It's been great. Don't go it alone.
It's not a social journey until others join.
Share this with your friends.
