[REPLAY] Personalised Health: Looking at Different Health Types and Genetics with Dr Cam McDonald

Many popular diets and exercise crazes assume that they're going to work on everyone who tries them. However, every human being is unique. Health isn't one-size-fits-all. What works for one person may not work for you — it might even be detrimental! That's why we need to personalise our health programs to suit different body types.

Dr Cam McDonald joins us in this episode to discuss the importance of understanding your biology to personalise your health program. He talks about the role of genetics and epigenetics in determining your bodies' specific tendencies towards stress and food. We also delve into the different body types and what diets and exercises are most suitable for each one.

Tune into this episode if you want to learn more about personalising your health program based on your genetic make-up.

Episode Highlights [01:31] Why Personalisation Is Key

• Every individual is different, but we keep applying the same health approaches to everyone.
• Misalignment between the body and its environment causes diseases.
• Personalising your health helps you align yourself with your environment.

[06:45] The Science of Chronobiology

• Chronobiology is how our biology interacts with time.
• Examples of chronobiological processes are our circadian rhythm, menstrual cycle, and ageing.
• Our bodies have a rhythm that follows along with sunlight.
• When people are active at night, it disrupts their system. This disruption creates hormonal irregularities, leading to diseases.
• Listen to the full episode to learn more about chronobiological processes and how they affect our health.

[18:24] The Genetic and Epigenetic Component of Circadian Rhythms

• People have different chronotypes which are based on when their bodies can tolerate stress.
• Some people are 'Activators'. Their bodies respond best to adrenal systems. In turn, they have energy that matches their strength throughout the day.
• 'Diplomats' have bodies that respond better to their digestive and nervous systems. These people are more at risk for fluid retention, tiredness, and weight gain.
• Muscle and fat production relies on the hormones stimulated by food and exercise.

[27:50] About Food Timing

• 'Crusaders' have bodies that are neurally-driven and are not prone to obesity.
• Because Crusaders are more likely to lose muscle, they are recommended to eat several small meals per day.
• 'Guardians' have thick joints and big muscles. However, they also have the greatest capacity to store fat.
• Guardians are recommended to have two meals per day (breakfast and lunch) and a very light, if not non-existent, dinner.

[38:41] Intermittent Fasting for Crusaders and Guardians

• Because Crusaders are always on the edge of their fuel supply, intermittent fasting will impact their stress levels more.
• Crusaders should only do one day of intermittent fasting per week.
• Guardians, however, can go for extended periods of fasting because their rhythms are slower.
• Being in a peaceful environment helps manage stress levels and makes intermittent fasting more tolerable.
• Intermittent fasting and autophagy do not necessarily work for all.

[45:08] More About the Guardian Body Type

• Because Guardians have strong and resilient bodies, they're more likely to survive if there were a lack of food supply.
• A Guardian's body is that way because in nature, they protect their community.
• 'Sensors', another ectomorph body type like the Crusaders, prefer nutrient-dense foods like vegetables.
• Guardians, however, like high-calorie foods more because they provide a feeling of safety.

[54:48] Dominant Hormones for Different Body Types

• The dominant hormone for Guardians is prolactin—a 'caring' hormone.
• Diplomats search for a balance in serotonin—a hormone that you get as a reward for pleasurable things. This makes them assess an activity carefully if it's going to be rewarding.
• Activators search for adrenaline, so they always want excitement and action.
• Crusaders' dominant hormone is dopamine, which creates drive and focus.
• Listen to the full episode to learn more about the different body types (like 'Connectors' and 'Sensors') and their dominant hormones.

7 Powerful Quotes from This Episode

'We know that everyone's different, but then when we go to actually doing the thing, we apply the average, or we apply what we think is appropriate thinking that everybody else is the same. So we have this disconnect between knowledge and action.'

'The mind is also on a clock of its own. Essentially, if you're exercising at the wrong time, you set up the wrong kinds of hormones, then you can actually create complete stasis in your health.'

'There's a full continuum of where people are. This is based on not just their wants to wake up. . . it's actually as to when a body can tolerate stress, and how that stress should be placed on them.'

'Whether you put muscle or fat tissue on, it's actually not to do with your food or your exercise, it's got to do with the hormones that those foods and exercise stimulate.'

'It's not a one size fits all when you hear everybody talking about intermittent fasting or doing these things—autophagy, inhibiting mTOR, and all those sorts of things.'

'The reason that their (Guardians') body is built the way it is is [because] when we go through famine as a community, their body goes into conservation. They essentially start growing, or they start slowing down their metabolism so that they can provide food for everybody else.'

'If you put your body in the right environment, get the right foods, eat at the right times of the day, work and do your mental stuff, you'll get health and you'll get optimal performance and you'll get longevity.'

Lisa Tamati: Well, hi everyone and welcome back to Pushing The Limits. I'm super excited to have you here with me again. Today, I have another superstar, Dr Cam McDonald, all the way from Australia. And he is one of our mentors and teachers here. He is the CEO of ph360.me. So people are listening out there, you've probably heard one or two episodes where we've talked about genetics and epigenetics and how to understand your genes. Well, that's what we're going to be talking about today. And Dr Cam is an absolute expert on this. So welcome to the show, Dr Cam.

Dr Cam McDonald: Thanks, Lisa.

Lisa: Great to have you again.

Dr Cam: It's great to be here. It's been a long time between chats, but there's been an awful lot of interaction between. It's always been great.

Lisa: Yes, so you're our repeat offender on the show. But I think it was a good couple of years ago now. So I mean, meanwhile, we've dived deep into the world of epigenetics with you and learned from you and learned a ton of stuff. Way overdue that we had this conversation and started to share a little bit of your knowledge and the amazing things that we can now do with genetics and understanding how we run.

So everything in regards to epigenetics and genetics is all about personalising everything to your specific set of genes. And this has really been a game-changer for us personally and professionally, for our athletes, for people that we're working with, in the corporate setting and everything because everything should be personalised now, shouldn't it? Should we start there? I think that's a good place. Why is personalisation key?

Dr Cam: Yes, I mean there's a number of reasons why we definitely should be personalising. But the first is that we actually have the knowledge now, that's one thing. We have an understanding of how we can actually do this. I guess for our long history, and I guess for the history of the people that are alive, the people listening to this right now, we always know innately, 'I'm different to that person'.

But then, when we go to recommendations. And when we go to how we go about our life, whether it be the job that we're sitting in, it's like, 'You have to do this job in this way' or 'You can't do that great. We'll get someone else to do this job this way'. Like you must do this job this way. You must, 'Oh, you're going to get fit? Great? You go to this gym, and you do this boot camp. Everyone goes to this boot camp because that's what is going to be great for everyone because the latest science says this'.

And when it comes to food, it's like 'You should definitely do this because this is what the average of everyone should do'. And so we know that everyone's different. But then when we go to actually doing the thing, we apply the average or we apply what we think is appropriate thinking that everybody else is the same. So we have this disconnect between knowledge and action.

And so why we need to? I guess what we know now is that the timing of your food, the timing of your exercise, the type of exercise or foods that you're consuming, the type of work that you're doing, the types of interactions that you're having, if you don't get that right, it creates disease. If you align your body with its environment, then your body goes into a healing and recovery state, and you get healthier. But if you misalign, and that can just be getting up at the wrong time, and we see this with shift workers all the time—the longer that they do shift work, the more likely they are to die prematurely.

And this is when you get a misalignment with the body and the environment. But the really incredible thing is now, it's not just that we all should avoid shift work, it's rather that some people are going to be better suited to it than others. And when it comes to every other domain of life, there's going to be something that is great for one person. Like a big Gatorade is going to be the best thing ever for a runner during their race for it's in the mean of best thing ever, and I'm not attached to Gatorade as a brand.

But let's say that you have some sort of electrolyte fluid as a drink. And that's going to be fantastic for a marathon runner 30K's in versus a person who's been sitting on the couch for the last six years and has a significant waist circumference and diabetes.

Lisa: Disaster.

Dr Cam: That drink is diabolical. And so, when we start thinking about personalisation, we start thinking about, well, 'What's going to help this person align and perform'? Because if you misalign, it creates disease. So that's another motivation.

And then I guess, as I started, we now have the understanding of how people are different, what people need to do about it, and we've got some really wonderful results on if we apply that to these individuals, they're going to get a great result for themselves. It's now the time that we can act on this innate knowledge that we've always had but do it in a very intelligent way.

Lisa: And do it in a very structured way. A great example of this is that the whole fitness industry was really run by people with a certain type of genetic combinations. And so we trained, and I belong in that group, and you belong in that particular group. We train people we like to train and how we see benefits. We see benefits from the way that we train—high-intensity workouts and getting up early and training. Well, that suits you and me, right, Dr Cam? Because we're very close on the epigenetics wheel, if you like, have similar genetic makeup. So that works for us. Whereas it doesn't work for someone on the other side, so who's more that of the endomorph type of body.

So I've used this example before, but my husband, I used to make him get up at five or six in the morning and do a CrossFit workout when he's what they call a Diplomat. And now in that terms, which means he has a different set of genetics, basically, that is not suited to getting up at that time and doing that type of workout. Both are wrong for him. From a chronobiological perspective, he should be in bed because his testosterone, his hormones are doing their thing at that time in the morning. So that was a problem.

Number two, I had him doing a type of exercise that was wrong for his body type. His ATP doesn't replace as quickly, and his cells are doing back-to-back sets just seem to map on a stress reaction. So his cortisol would be up, and then it would be up for the rest of the day. And what have I done to my poor husband? I've made him actually put on weight and not get further and feel like crap all day. So whereas for me, that same class, that same set of exercises, that same time of the day, perfect, and I'm good to go, and I'm really rearing to go. So that just gives you a little bit of an example.

So today, let's look at chronobiology because this is all about at the timings of when to do what. So can you explain what the science of chronobiology is, Dr Cam, and how it applies in this situation?

Dr Cam: Yes, absolutely. So chronobiology is how our biology interacts with time. And we know about this because we all get older—that's a chronobiological effect, is that we get older. But what's really interesting as well is that within because of the sun, and it's showing its face every day or so. It comes along at about 6 am and then leaves at about 6 pm whatever it might be. Because we've been living on this planet with this big stimulant from the sky, essentially our bodies have got adapted to things happening in a rhythm.

And so, it's just like we wake up, and then we go to bed, we wake up and then, that's a daily rhythm. We have a menstrual cycle. We have ovulation. We go through the menstrual period, and that happens on a 30-day cycle. We then have our early life. We have our middle age, and we have our later life. That's another cycle.

Even a yearly cycle as well, we have the circannual cycle. And so, we have seasons. So winter, it gets colder, and our body does different things. And so, essentially, now that we understand that we got these different patterns of time that are occurring, our body is constantly responding to cues from the outside.

And so where this work first came about was they started looking at shift workers instead of wondering why all of these people were getting so much more cardiovascular disease, diabetes. And they found that if you're waking up at night, and you're getting lots of light, and you're getting food at night as well—all of those things, tell your body, 'Hey, you should be awake'. And so it wakes the body up.

But you've got this momentum of a cycle that's coming from generations of being exposed to the sun and sleeping at night, and all of our physiological systems are actually setting up for us to sleep at night and rest and recover and do a whole lot of things that definitely don't require doing heavy work or digesting food as much. And so we get this disruption. We get things happening and things being signalled to the body that shouldn't be signalled at that time, which creates irregularity in the hormones that flow through our body. Our cortisol, our melatonin, our testosterone levels, our adrenal levels—all of those things get shifted out of whack when we give ourselves an artificial time input. So we want to—essentially, the first and foremost, the first thing that we gauge what time it is is what amount of light we have.

Lisa: How much light, yes.

Dr Cam: Yes, and then when we get—when the sun comes up in the morning, it sets off this cascade of wakefulness. It takes us from dead asleep to awake in a very short period of time. There's a big hormonal shift that occurs to make that happen, and it maps into sunlight. And so, as we go through the day, we have this homeostatic drive of 'The longer that I'm awake, the more I want to go to sleep'. That's a natural thing that we have. The more that you run, the more that you want to stop is another way of thinking about this one. So we have this—as the day goes on, you get more tired.

And we then also have these rhythmical changes. Essentially, it's not the homeostatic drive for tiredness, but the circadian drive of tiredness, and you'll have peaks in your day, or maybe in the afternoon, you're firing. Other people are really, really tired that they wake back up at night. Some people are really energised in the morning. We have all of these different things that are happening throughout the day as well. So to simplify all of this, our body is designed to rouse with early morning light or rears with light. We then are meant to—essentially, our body is searching for the rhythm that suits our body.

And what's really interesting, if you take light away from somebody—and I know I'm jumping all over the place, but I will bring this all together. So if you take light away from somebody. A great guy did an experiment on this way back in the day. He sat in a cave for a couple of months and with no changes in light at all, just exactly the same ambient light the whole time. And what happened was, his rhythm went to 24 and a half hours for a daily period. So what happens is, if we were to not have any sunlight input, we would run on a 24 and a half-hour cycle. And the was out of sync by a few days after a couple of months.

Lisa: After a couple of months.

Dr Cam: He actually—and he thought it was only a month that passed, it was two months that passed. His time really—oh no he thought it was three months that passed. It was only a couple months because time really slowed down. And so what we know is that inside our body, we have a rhythm.

Lisa: Yes.

Dr Cam: But that gets reset every day with the sunlight. And so, and it actually keeps us on track with the hormones that have been flowing as a result of that sunlight. So sunlight is one time giver. And if we disrupt that, it creates lots of disease in that shift work. Not only does your waist circumference get bigger the more shift work you do, all of the risks—cancer, diabetes, heart disease—increases the longer you do shift work.

Lisa: Wow. Wow.

Dr Cam: And what we see is if you disrupt a body for three days with bright light at night, they start looking like they get diabetes. Their insulin resistance changes.

Lisa: Instantly?

Dr Cam: Within a few days, you can start disrupting these cycles of hormones, which makes your body say, 'Well, there's something wrong with this environment. Why am I awake at a time where I shouldn't be? Well, there must be something wrong. Therefore, I'm going to start conserving. I'm going to start going into a stressed state so that I can escape and protect myself', and diabetes is just the ultimate protection—starvation protection that makes you gain weight very easily. And so, after a few days, four days, you can actually start seeing some changes in metabolism if you're out of sync with your sleep alone, then four days to correct it. So you can actually get back on track very quickly.

Now, light isn't the only time giver, there is also heat that you have in your body. Food is also a time giver. Exercise is also a time giver. And so if you eat regularly at the same time each day, your body will start falling into a rhythm of 'I expect food', and this is what happens when you change your diet. Some people go from six meals a day to two. Let's say they're doing some fasting or something like that. They'll be really, really hungry at the times that they were eating when they're doing six meals a day for about a week.

Then what happens is each cell in our body has its own timekeeper as well. The master clock is coming from the sunlight, and then each tissue in our body has its own timekeeper. And so our gut takes about a week to correct itself, and then it starts getting on track with the new routine, and so then, it starts setting up for the new routine. Therefore food, it gives time to the body, it actually gives the schedule. And along with that food intake comes insulin release, hormone release, all of those types of things.

But then the really important thing we need to consider is if you don't stimulate the body at the right time to get the right hormonal outflow, you start going into disease. And so, if you're eating food at the wrong time, you're stimulating these hormones just as if you were not sleeping at the right time. If you're exercising at the wrong time. Let's some bodies are really, really well adept at tolerating stress in the morning. If you exercise, that's a stress.

Lisa: Yep.

Dr Cam: You give your body that 'Stress is coming now'. And if you do that regularly, your body's gonna say, 'Okay, stress is coming now'. It prepares itself, and it deals with it quite well. But then if you take a night owl, and you give them that same stress in the morning, it gives them the time of stress in the morning, but their body is not set up for stress at that time of day. And so they start trying to compensate later through weight gains, like 'I spent all of this energy at the time that I didn't want to. I wasn't set up for it, so I'm going to have to conserve my energy because something's wrong'.

Lisa: That's what I was doing to the husband.

Dr Cam: Yes, absolutely. So what you see in a practical sense—and I'll just say one more thing as well, that the mind is also on a clock of its own. And essentially, if you're exercising at the wrong time, you set up the wrong kinds of hormones, and you can actually create complete status in your health. As in it doesn't get any better even though you're working really, really hard or can sometimes take you backwards.

And we're seeing this with some diabetes now is really high-intensity exercise in the morning, in some studies is indicating worsened blood sugar levels at the end of the day because everybody goes into survival of 'Oh, this environment is really stressful'. So where you position things in your day…

Lisa: It's crucial.

Dr Cam: ...sets a rhythm. But if that rhythm doesn't align with what your body needs in order to be in its best health, then it creates disease. And that disease, obviously, tracks down pathways of compensation and stress, and you end up with a body that has been getting up eating five meals per day, has been doing the early morning exercise, just like your husband.

Lisa: Yes. They're getting nothing out of it.

Dr Cam: And because they're putting stress out in the morning, they're giving them too much insulin response throughout the day because their bodies just not designed to get five hits of it throughout the day. Some bodies are, some bodies are.

Lisa: Yes.

Dr Cam: After 12 weeks, they've gained a kilo and got a bad knee. And they're wondering, 'What the hell is going on'?

Lisa: And they've been a super disciplined person getting up. And I mean, just to give you a couple of examples of the set of my life because I like to put things into stories.

Dr Cam: Yes, please.

Lisa: So that people actually get the science. Six months ago I went through this terrible time with my dad, who was unfortunately dying and passed away in July. In the 16 days that we were in the hospital battling for his life, I was round the clock with him. Now my blood sugar levels went through the roof. So afterwards, I was showing like diabetic levels of blood sugars—fasting blood sugars because I was so out of whack and so stressed alongside of it. And it took me a good two to three months for me to get my body back into rhythm. So that was just 16 days of sleep deprivation, being up all night, hardly any food, in this case, was actually sharp throwing my blood sugar's up through the roof and the stress hormones that were coming out. So that's a really extreme example. And obviously, that was for a specific purpose.

And I've seen this also with ultramarathons that I've done, that I've been going for days on end. You would think that a person who was exercising 24/7, around the clock, sort of thing for not seven, but let's say two, three days, that they would lose massive amounts of weight, and so on. And I would actually put on weight when I did ultramarathon. So I typically lose it initially, and then I would have all this weight gain. And then I would have this response. And within a month, I would be usually heavier than when I started, which was really frustrating.

Dr Cam: Yes.

Lisa: So this stuff matters, and this stuff is really, really important. And I've done podcast episodes already on circadian rhythms in regards to light and why we need to block out blue light at night time because, again, that's giving us a signal to stay awake and stopping our melatonin production.

And the example there with the cortisol, right? We want cortisol. We want these stress hormones at the right times of the day. So there is also a genetic component to this. And this is where, what we do at ph360, and what we find out in the programme that we run is looking at your specific genes in relation to circadian rhythms. Can you explain a little bit?

So why is it for my husband that if he gets up at 5 am and does that, that's not good for him? Whereas for my body type, that's not so bad?

Dr Cam: Yes, sure. So when we're talking about this, there is a genetic component, and I guess what we're going to be talking about today and what we've kind of alluded to is that there's also an epigenetic component. And so when we talk about chronotypes, and whether someone's an early bird, a night owl, or an intermediate type, or somewhere in between because there's a full continuum of where people are. This is based on not just their wants to wake up, not just that 'I can wake up', I'd prefer to sleep in', or 'I'd prefer to wake up early'. It's not necessarily that. It's actually as to when a body can tolerate stress and how that stress should be placed on them.

And in our body, at all times, there is a system of stress and then recovery, and it's that balance that we're trying to fluctuate through with our rhythms throughout the day. That's actually what the rhythms protect is that stress-to-recovery balance. So waking and then sleeping and then eat and then rest or, move, eat, rest, all of those types of things.

So, we have individuals that as they're developing in the womb, they get a heightened sensitivity to testosterone, they have a greater development of their adrenal system and their response to adrenaline, and that's due to embryological epigenetic factors. And to make that simple is that there's different tissues that are developing in the womb, obviously, that make up our body. Depending on the genes that you have and in the environment in the womb, you will give more dominance to certain tissues. And this particular person, they called the Activator in our ph360 circle. The Activators have, they develop the tissues more dominantly that are related to the muscle, the skeleton, the testosterone, and the reproductive glands, adrenal glands, kidneys. And so as they develop throughout their life, these hormones and these tissues have more dominance than the other tissues.

And so, I'll give another example just to give a comparison in a second. So if you've got a body that's more sensitive to testosterone, it also has a slightly stronger adrenal system. And Lisa is a perfect example of that, and I'm not too far from that.

Lisa: Yes.

Dr Cam: And essentially, what this body does really well is that it responds to that adrenal system very powerfully. And first thing in the morning is when your adrenal system is the strongest. This is when you get the biggest glucocorticoid release that's your cortisol and your adrenalines. And essentially, it's to say, 'Hey, you were dead asleep, and now you need to be awake'.

And because they've got tissues that are also ready for that, they even take that energy. And if they use their adrenal system at that time, it matches their strength. This is what they've grown to be strong in. And so it matches their strength to be really great at this. And so, when they use it, it aligns with what their body is looking for. And then they ride that energy all the way through to the end of the day. And this is because we've put the right body into the right environment at the right time.

However, a Diplomat, which is the opposite side of the circle, and what we see with embryological development is, on a circle, opposite sides, you'll see opposite effects. And so, instead of it being the adrenal system and the testosterone system that's really sensitive within the body, the other body, we actually see their digestive system and their neuro system being more developed and more sensitive.

And so what's happening in digestion in the morning is that it's, essentially, it's regulating where all the fluid is going to go in the body. It's finishing off these really important digestive processes, clearing out the digestion, making sure that the gut is rested and ready for new meals. And it's doing that right up until 7am.

And so this body is having to focus all of its energy on its digestive system because that's the really important system for this body. And if you then stress this body, what happens is it goes, 'Well, I was trying to put water into the right place, I was trying to get my digestion on track, and I'm running all of a sudden'?

Lisa: You're just taking what. Yes.

Dr Cam: 'Like this does not match at all. I don't need adrenaline right now. This is bad news'. And so what happens is the body then goes into compensation. It says, 'Oh, God. Well, I'm gonna have to make up for this later. I've spent all of this fluid of sweat. I've used all of this energy'. And so this body goes, 'Well, I didn't get time to put my fluid away, so where is it? Okay, I'm going to retain fluid now', because, and this is exactly what happened in that body.

Lisa: You've put on weight.

Dr Cam: You have enough cortisol at the wrong time.

Lisa: Yes.

Dr Cam: They make that retaining fluid. And this is exactly what's happening—they get the adrenal burst in the morning, but if they then run with that with some morning exercise, it becomes too much for their system. They can't then do those digestive processes. Their gut goes off, which influences their serotonin production, which makes them less happy.

Lisa: Wow.

Dr Cam: What's really interesting with this kind of crowd is that the things that we'll see is an individual wakes up, like I said before, we'll get up, and they'll do their exercise. And what they'll notice is they start getting this bit of weight around the middle.

Lisa: Around the middle.

Dr Cam: And they'll also start accumulating fluid. They'll get a halo effect from exercise of two to three hours because their stress levels actually stay a lot higher for a lot longer because they shouldn't be stressed at that time. So they get this, and stress hormones make you feel alive, and they make you feel awake. And so, for the first three hours of the day, you're going, 'Yes, I'm an early bird. This is awesome', and then come lunch, it crashes really, really hard. And you also become more diabetic in the afternoon, for lack of a better term, more insulin resistance.

Lisa: Insulin resistance

Dr Cam: Yes. And so, this individual has been working their guts out literally, and all they've got is more fluid retention, tightness in the afternoon, weight gain around the middle, which is the thing that they're doing exercise for.

Lisa: They're stuck.

Dr Cam: And if they just shift that exercise later in the day when their body is ready for movement because this body likes to conserve energy in the morning, make sure everything is sorted in their body, and then they can move in the stress and all that sort of stuff in the afternoon. And if they do that, there's no cortisol rise to the same extent. They have much lower cortisol all day, which means they don't deposit fat around their stomach.

Lisa: Because cortisol is a real effect on…

Dr Cam: Huge one. And this particular body, absolutely, because it's the opposite of the Activator, the Diplomat is, they don't like their cortisol so high. They like things to be cruisy and peaceful and steady as opposed to high-intensity and… Exactly. And so, whenever you put this body into this thing at the wrong time, you end up with this adverse effect. And you start questioning yourself, it's like, 'What the hell could I be doing better? I'm waking up, I'm getting my food in…'

Lisa: 'I'm useless'.

Dr Cam: '...I'm doing the things I'm supposed to do, and then I'm crashing in the afternoon'. And all of a sudden, now they're having three or four coffees, which is just another stimulant of cortisol.

Lisa: Yes.

Dr Cam: And then they worsen the effect. And so we see for this person, if they just sleep in, they actually start losing weight faster than if they exercise. And this is…

Lisa: So counterintuitive.

Dr Cam: So counterintuitive. But when you think that whether you put muscle or fat tissue on, it's actually—not to do with your food or your exercise, it's got to do with the hormones that those foods and exercise stimulate.

Lisa: Yes.

Dr Cam: You don't grow muscle from protein alone. Because we'll see people in hospital who are malnourished, and we're feeding them lots of protein and they just burn then they lose weight. What we're trying to do is we need to modify the hormones. And if we get the right rhythm to our day—cortisol is acting, testosterone is acting at the right time, growth hormone is acting at the right time—if we were able to match our day with our hormone release that's relevant to us, then our body is able to—anytime that it gets some protein, is able to put it to work rather than burn it off in stress.

Lisa: Wow.

Dr Cam: And the same thing with exercise. If you do exercise stress at the right time, you stimulate the right growth hormones, which like in ultramarathon running, and I use this example all the time, it's just so appropriate right now. If you run for three days, are your muscles bigger by the end of the three days?

Lisa: Hell, no

Dr Cam: Exactly. They're broken down. Exercise is a stress, and it just stimulates your body to say, 'You need to be stronger here'. So this is where—whenever you're thinking about exercise and food, you've got to be thinking about 'What hormones am I modulating here? And what hormones do I need right now'? And that's the information that we can have. Just two very simple examples that we provided before.

Lisa: Yes, and this is why this information in the programme that we do is so powerful because it gives you that specific information along with a ton of other things about what time to do things and when, in optimising your whole daily rhythms. But it isn't just about exercises, it is also about the food timing. So let's look at a little bit into the food timings and then also the whole neurotransmitter side of things.

Dr Cam: Yes.

Lisa: Like when am I going to get the best out of my brain? All that type of stuff as well. So from a food perspective.

Dr Cam: Yes.

Lisa: So you and I are Crusader. I'm a Crusader-Activator on the cusp there, means four to six meals a day is ideal for us or regular food. My mum's a Guardian. Opposite end of the wheel, again.

Dr Cam: Yes.

Lisa: Two to three meals a day, ideal. That doesn't mean that you and I can't do intermittent fasting. That doesn't, by the way. We can still do that and get the benefits of autophagy and stuff, but it's a shorter fast from what I worked on.

Dr Cam: That's exactly right.

Lisa: Yes

Dr Cam: Yes. And that's the perfect—I was actually going to use those two examples for that, Lisa. Spot on. So we've got Activators and Diplomats, which we've spoken about. Then, we got the Crusaders and the Guardians. So Crusaders are, essentially, Lisa's a really good example, I'm a good example.

Generally slight like a soccer player—taller, leaner, slender. And one of the features of their body is that they're very neurally-driven. So as opposed to adrenaline and testosterone, as opposed to digestive, the Crusaders are very neurally-driven. Everything is about mental focus, mental drive, and creation of hormones that allow you to keep driving forward. And you see these types of people in triathlons and marathons and anything that requires that long-term high-intensity focus.

Now, with this body, not prone at all to obesity. You have to really, really really push with bad habits to get this body to a level of obesity versus the Guardian. Naturally, this is your strongest, thickest jointed, biggest muscled, and also, they have the greatest capacity to store fat. So anyone that you see at powerlifting or in shot put or in those power sports, like the world's strongest men. Oprah is a good example of a Guardian. This is a body that's just more substantial.

And so what's really interesting about these two bodies is that—and I guess the most relevant one, we can start with the Guardian because it's kind of interesting. And then we'll come back to the Crusader, which is more—the most appropriate for general healthy guidelines than any other one.

Lisa: So we run the show as far as…

Dr Cam: We have the other types.

Lisa: ...we have told everybody how to do it all wrong.

Dr Cam: Well, and what's really interesting is that our bodies—because we're unlikely to be obese just with the way our body is made up. That's not good or bad. We die from other things, by the way. We may not die from diabetes.But we might get...

Lisa: What can else haunt us?

Dr Cam: Exactly. Yes. There's Parkinson's or something not so pleasant like that. So essentially, when we're feeding a Guardian, they've got a body, they walk past a bakery, and they smell it, and they gain weight.

Lisa: Yes.

Dr Cam: They have this ability of just accumulating mass at all times. But they have these hormones in their body, and they're more sensitive to prolactin, and they produce more insulin. And these hormones are growth hormones. They make you grow. And so, they have an abundance of these things going on. They have a slightly slower thyroid, which means that they are able to conserve weight very easily. And what's really interesting, psychologically, they're being driven to care for people. So they have the most ability to conserve energy and the most ability to nurture. So you have these big, strong protective individuals.

Now what's really interesting with the timing of food, they're recommended to have two meals per day, breakfast and lunch and then a very, very light, if not, non-existent dinner. Now, the reason that we do that, particularly with Guardians who are feeling like they wanting to—because this is the body that's most prone to excess weight gain as well. They'll be
