00:00:00.089 --> 00:00:02.250
Welcome to episode 32 of the cancer pod.
00:00:02.490 --> 00:00:07.459
In this episode, we talk about that low carb diet, you know, the one everybody's talking.
00:00:08.160 --> 00:00:09.179
Where did it come from?
00:00:09.390 --> 00:00:10.380
What is it good for?
00:00:10.470 --> 00:00:14.189
Can it help cancer patients stick around to find out these answers
00:00:14.189 --> 00:00:16.260
in more, um, Dr.
00:00:16.260 --> 00:00:19.620
Tina Kaeser and his lay likes to say, I'm the science one.
00:00:19.920 --> 00:00:20.399
I'm Dr.
00:00:20.399 --> 00:00:21.780
Lee Sherman and I'm
00:00:21.780 --> 00:00:29.460
the cancer insider, and we're to naturopathic doctors who practice integrative cancer care, but we're not your doctors.
00:00:29.670 --> 00:00:34.439
This is for education, entertainment, and informational purposes only do not
00:00:34.439 --> 00:00:36.090
apply any of this information.
00:00:36.119 --> 00:00:37.439
Without first speaking to you.
00:00:38.429 --> 00:00:44.100
The views and opinions expressed on this podcast by the hosts and their guests are solely their own.
00:00:44.520 --> 00:00:46.079
Welcome to the counselor pod.
00:01:02.729 --> 00:01:03.270
Hey Tina.
00:01:03.780 --> 00:01:04.170
Hey Leah.
00:01:04.590 --> 00:01:05.939
So we've got a new series
00:01:06.120 --> 00:01:07.530
pod series.
00:01:07.620 --> 00:01:08.219
Yeah.
00:01:08.370 --> 00:01:08.700
Yeah.
00:01:08.730 --> 00:01:10.349
Kind of straighten things out a little.
00:01:11.219 --> 00:01:13.890
Maybe talk about some, not so convenient truths out there.
00:01:14.370 --> 00:01:14.849
Yeah.
00:01:14.849 --> 00:01:20.219
So there are things that patients, you know, they hear from other people you've got to take this, you've got to do this.
00:01:20.219 --> 00:01:24.150
You've got to not eat this because it's good for cancer cancer in general.
00:01:24.780 --> 00:01:32.939
And so we're going to take a look at whether it's a, a supplement or a diet or just some sort of recommendation.
00:01:32.939 --> 00:01:37.500
And we're going to kind of break it down and see, is this the cancer cure hall, right.
00:01:37.680 --> 00:01:37.890
That
00:01:37.920 --> 00:01:38.400
it's claimed.
00:01:39.150 --> 00:01:39.840
Exactly.
00:01:40.200 --> 00:01:48.030
And we're gonna start today with the ketogenic diet, which I think a lot of people get recommended to them by well-meaning loved ones, ketosis,
00:01:48.060 --> 00:01:49.049
ketosis.
00:01:49.079 --> 00:01:50.069
That's what we're talking about
00:01:50.069 --> 00:01:52.920
today, where the question is is, is ketosis.
00:01:53.909 --> 00:01:57.180
Truth about ketosis, actually the
00:01:57.180 --> 00:01:58.469
truth about the ketogenic diet.
00:01:58.799 --> 00:02:01.439
It's confusing because there's so many sources.
00:02:01.439 --> 00:02:05.310
So even if you're just sticking to the medical literature, it can be confusing.
00:02:05.340 --> 00:02:06.180
So yeah.
00:02:06.299 --> 00:02:07.620
Add some, uh, Dr.
00:02:07.620 --> 00:02:08.280
Google in there.
00:02:08.735 --> 00:02:11.794
Whatever your search engine is, and it gets confusing quickly.
00:02:11.914 --> 00:02:12.245
Yeah.
00:02:12.275 --> 00:02:12.664
I
00:02:12.754 --> 00:02:18.634
had to do a lot of research for this, cause I don't really talk diet with my patients because we have dieticians.
00:02:18.724 --> 00:02:22.895
So I was just kind of looking to see if there was anything new.
00:02:22.895 --> 00:02:25.555
And I noticed I did a search in my.
00:02:26.294 --> 00:02:28.634
Inbox on Quito.
00:02:28.724 --> 00:02:34.694
And it seems to be like, kind of a, like, even a bigger thing in the medical newsletter world.
00:02:34.694 --> 00:02:36.944
Like there's a lot of information that is out there now.
00:02:36.944 --> 00:02:38.145
So I think it's even becoming more
00:02:38.145 --> 00:02:38.745
confusing.
00:02:39.224 --> 00:02:39.884
Yes.
00:02:39.914 --> 00:02:40.965
And you know what?
00:02:41.085 --> 00:02:42.104
I'll admit to something.
00:02:42.164 --> 00:02:46.185
I do not read anything, but the medical literature on ketogenic diet.
00:02:47.354 --> 00:02:48.974
'cause, I don't want to confuse myself.
00:02:49.094 --> 00:02:59.715
I don't want the onslaught of, you know, public facing health information because a lot of that is put out by industry or by interested supplement companies that might skew the information.
00:02:59.715 --> 00:03:04.875
And so I stick to ketogenic diet in the realm of cancer care specifically.
00:03:04.875 --> 00:03:09.884
So I just stick to the reliable stuff, knowing that if I read it, then I read it from a reliable source that way.
00:03:10.245 --> 00:03:10.514
And the
00:03:10.514 --> 00:03:14.474
cancer part of it is, I mean, relatively new because.
00:03:15.719 --> 00:03:21.659
Initially, it was used as a treatment in the early 1920s for epilepsy.
00:03:22.020 --> 00:03:24.689
And they used it before the drugs ever were invented.
00:03:24.689 --> 00:03:33.389
I mean, they didn't know the drugs were going to be invented, but this was the, this was the standard treatment until anti-epileptic drugs were created.
00:03:33.810 --> 00:03:38.129
And then it kind of fell out with popularity until.
00:03:39.074 --> 00:03:46.064
Yeah, it fell out of favor because phenobarbital, I think was the first or something of the sort was one of the first anti-seizure medications.
00:03:46.064 --> 00:03:49.004
And then there were some children, especially with epilepsy.
00:03:49.889 --> 00:03:57.689
Didn't have controlled seizures with the drugs and my recollection, although I don't know if I can find this again, 20 years ago.
00:03:57.689 --> 00:04:08.400
I remember reading and I think it was through the Charlie foundation, which is a foundation that was founded on promoting the ketogenic diet for epilepsy specifically.
00:04:08.849 --> 00:04:13.439
I remember in their materials a long time ago during my residency, when I was reading it, that there was a nurse.
00:04:14.264 --> 00:04:18.704
Johns Hopkins that remembered the old ketogenic diet protocol.
00:04:18.944 --> 00:04:23.264
And she kind of was the, the one practitioner keeping it alive.
00:04:23.504 --> 00:04:24.014
And the whole
00:04:24.014 --> 00:04:27.435
Charlie foundation there's in there a movie based on that story too.
00:04:27.555 --> 00:04:27.975
Okay.
00:04:28.185 --> 00:04:32.235
For anyone who's interested, but yeah, there there's a movie based on the story of.
00:04:32.750 --> 00:04:33.439
The little
00:04:33.439 --> 00:04:33.889
boy.
00:04:34.009 --> 00:04:34.399
Yeah.
00:04:34.430 --> 00:04:35.389
Whose name was Charlie?
00:04:35.389 --> 00:04:41.029
And he had seizures that couldn't be controlled with medications and had seizure control with a ketogenic diet.
00:04:41.060 --> 00:04:47.720
And then the foundation was founded with the mission of bringing that to children, with epilepsy who needed to have seizure control.
00:04:47.899 --> 00:04:50.720
So through that we know a lot about the ketogenic diet.
00:04:50.720 --> 00:04:53.089
So one it's been used for a very long time.
00:04:53.180 --> 00:04:54.709
So we have lots of information on it.
00:04:54.860 --> 00:04:59.689
It is used safely and can be used safely with guidance, professional guidance.
00:05:00.779 --> 00:05:05.519
So that that's a lot of evidence just right there to say, okay, this is not just fly by night.
00:05:05.519 --> 00:05:06.449
We didn't just make it up.
00:05:06.689 --> 00:05:08.040
You know, in the last 20 years,
00:05:08.370 --> 00:05:14.610
even though it is popular, like you go to the grocery store and you see things like keto donuts and keto bread, like all of that kind of stuff.
00:05:14.790 --> 00:05:18.870
Like it's kind of, I don't want to say jump the shark, but it's kind of jumped the shark.
00:05:19.170 --> 00:05:19.709
Yeah.
00:05:19.829 --> 00:05:22.230
We need our own term and natural medicine for when things do that.
00:05:22.930 --> 00:05:27.759
As jumping the sharks based on that happy days episode where Fonzie goes over to the sharks.
00:05:27.790 --> 00:05:27.939
Yeah.
00:05:28.120 --> 00:05:28.779
He literally
00:05:28.779 --> 00:05:29.560
jumps the shark.
00:05:29.560 --> 00:05:29.949
Yeah.
00:05:29.980 --> 00:05:30.339
Yeah.
00:05:30.399 --> 00:05:32.800
But that's kind of, yeah, that's kind of what happened with the keto diet.
00:05:33.819 --> 00:05:39.009
So maybe Tina, you want to explain what ketosis is, which is the foundation.
00:05:39.040 --> 00:05:39.970
Like that's the whole thing.
00:05:39.970 --> 00:05:44.350
That's the whole point of the ketogenic diet is to put the human body into ketosis.
00:05:45.009 --> 00:05:46.750
What the heck is ketosis
00:05:47.290 --> 00:05:50.170
by definition, the ketogenic diet is a high fat.
00:05:50.925 --> 00:05:52.425
Low carbohydrate low.
00:05:53.160 --> 00:06:09.750
Protein diet that I should say adequate protein, you know, not low as in deprivation, adequate, but low protein intake that puts the body into a state of metabolism that uses ketones instead of glucose as its major energy source.
00:06:09.930 --> 00:06:10.529
So
00:06:10.560 --> 00:06:14.759
our bodies use glucose normally for energy.
00:06:14.759 --> 00:06:16.500
Our brains use a lot of
00:06:16.500 --> 00:06:17.160
glucose.
00:06:17.759 --> 00:06:18.060
Yeah.
00:06:18.060 --> 00:06:21.149
So if you look at a cell, glucose goes into the cell.
00:06:21.819 --> 00:06:26.199
And that glucose basically gets modified.
00:06:26.230 --> 00:06:27.250
We'll just leave it at that.
00:06:27.699 --> 00:06:28.060
And we get.
00:06:28.980 --> 00:06:38.310
So instead of glucose going into the cell and making energy with ketosis, you have ketones going into the cell and entering a cycle that can then make energy within the cell.
00:06:38.310 --> 00:06:40.949
So you can run on ketones rather than on glucose.
00:06:40.980 --> 00:06:41.759
Your cells can,
00:06:42.779 --> 00:06:44.730
but it's getting it from fat.
00:06:44.759 --> 00:06:45.240
Yes.
00:06:45.269 --> 00:06:45.779
Right?
00:06:46.259 --> 00:06:54.509
So that's, that's the whole point of why it's like this high fat diet is because your body will convert and start to use fat for fuel instead of.
00:06:55.165 --> 00:06:55.884
Glucose.
00:06:55.944 --> 00:06:56.365
Right.
00:06:56.694 --> 00:06:57.055
Right.
00:06:57.084 --> 00:07:01.165
It's a little bit more intricate than glucose from carbohydrate, which is very simple.
00:07:01.464 --> 00:07:05.845
We can get, we all know that blood glucose comes from carbohydrates in our diets.
00:07:06.295 --> 00:07:09.055
Some blood glucose can come from proteins in the diet.
00:07:09.055 --> 00:07:10.944
It is possible to convert some amino acids.
00:07:11.470 --> 00:07:14.980
Over into glucose, but we cannot make glucose from fats.
00:07:15.069 --> 00:07:23.439
So when you put fats in your mouth, you're going to make ketones from them, but only when there's a metabolic necessity to do so.
00:07:23.529 --> 00:07:25.959
And that metabolic necessity is starvation.
00:07:26.865 --> 00:07:27.105
Right.
00:07:27.105 --> 00:07:30.944
So if there's no, the feast and famine idea is what we're built on.
00:07:30.944 --> 00:07:40.935
Our physiology is founded on the whole idea that sometimes of the year we are feasting and other times we have famine and that has to do with seasons and cycles and geography.
00:07:41.024 --> 00:07:46.605
Um, it's kind of amazing when you think about what a fast is, the body can run on very low.
00:07:47.295 --> 00:07:53.444
And when we don't have food going in, when we're truly fasting, ketosis is a survival mechanism.
00:07:53.685 --> 00:08:00.134
We go into ketosis to make sure that our heart and our brain and our liver and Al of our internal organs can function.
00:08:00.225 --> 00:08:00.435
So.
00:08:01.154 --> 00:08:10.035
When you think about it, it's a natural state of being, and I'm sure it does some physiological good to be, to be fasting because our bodies were made for that.
00:08:10.305 --> 00:08:10.605
Okay.
00:08:10.605 --> 00:08:26.819
So a ketogenic diet is low carb, but it's not no carb, but it may as well be no carb because if normally you eat between 200 to 300 grams of carbs, A day, the ketogenic diet limits at between 40 and 50 grams.
00:08:26.819 --> 00:08:30.629
So it's only five to 10% of your calories carbohydrates.
00:08:31.050 --> 00:08:35.610
And from what I was looking up, cause I have to look all this up because it's not something I recommend.
00:08:35.940 --> 00:08:40.559
Um, for women, they need to go more towards the 40 than the
00:08:40.559 --> 00:08:41.159
50.
00:08:41.399 --> 00:08:41.789
Yeah.
00:08:42.394 --> 00:08:46.684
And what I have seen in patients is it seems to be highly variable.
00:08:46.835 --> 00:08:52.774
I think it has a lot to do with how a person's physiology handles carbohydrates and how well they regulate it.
00:08:52.804 --> 00:08:58.174
So someone with trouble, you know, someone who's pre-diabetic, for example, might have to restrict it down to that 40.
00:08:58.264 --> 00:09:07.355
So in my experience, if there's some variability between people, but 40 to 50 is, is a good range, I think, to hit when you want to be ketogenic, it's very low it's.
00:09:08.054 --> 00:09:10.184
You know, it's not a convenient diet.
00:09:10.304 --> 00:09:18.914
I mean, online, you'll see a lot of variations, but what we're talking about is the medically therapeutic ketogenic diet, not
00:09:18.914 --> 00:09:20.565
the fad, not the fad.
00:09:20.565 --> 00:09:21.945
And you know, I guess, okay.
00:09:21.945 --> 00:09:22.934
Let's take a quick break.
00:09:22.934 --> 00:09:25.934
And then when we come back, we can talk about why people do the ketogenic diet.
00:09:26.684 --> 00:09:30.184
Beyond the fad beyond the Instagram posts
00:09:30.184 --> 00:09:30.904
and all of that.
00:09:30.965 --> 00:09:31.235
Yeah.
00:09:31.384 --> 00:09:32.315
All right, let's do that.
00:09:39.215 --> 00:09:40.924
So, Tina, what the heck are ketones here?
00:09:41.835 --> 00:09:51.674
Okay, so, oh, ketones, as in you take the fat in the fat goes to your liver and your liver kicks out these ketones as needed again, when it sees the necessity for this, right?
00:09:52.034 --> 00:09:57.975
When you don't have enough glucose, your liver will turn out the ketone bodies and there's only three beta hydroxy.
00:09:57.975 --> 00:10:01.304
Butyrate is the one that we talk about the most beta hydroxy butyrate.
00:10:02.294 --> 00:10:05.205
Measured in the bloodstream, then there's acetone.
00:10:05.534 --> 00:10:06.674
We all know acetone.
00:10:06.884 --> 00:10:07.184
Yes.
00:10:07.184 --> 00:10:09.044
It's similar to nail Polish remover.
00:10:09.434 --> 00:10:10.004
Yeah.
00:10:10.394 --> 00:10:11.024
And stuff.
00:10:11.144 --> 00:10:15.945
And acetoacetate is the last one, a CDOT acetate and beta hydroxy.
00:10:15.945 --> 00:10:17.804
Butyrate are the two that are used for fuel.
00:10:19.184 --> 00:10:23.865
Just an aside, they have that kind of sweet smell to them.
00:10:23.865 --> 00:10:27.644
So sometimes you can, you can smell this on someone's breath a little bit.
00:10:27.705 --> 00:10:28.575
You can smell.
00:10:28.664 --> 00:10:29.985
Do you remember juicy fruit gum?
00:10:30.825 --> 00:10:31.034
Good.
00:10:31.065 --> 00:10:31.424
Yeah.
00:10:31.424 --> 00:10:31.995
I love that.
00:10:32.054 --> 00:10:33.375
Yeah, it was delicious.
00:10:33.404 --> 00:10:34.514
Oh, it smells a little bit like that.
00:10:34.725 --> 00:10:35.475
Interesting.
00:10:36.044 --> 00:10:36.164
Yeah.
00:10:36.164 --> 00:10:41.264
I remember hearing about certain actresses on a very popular series in the nineties.
00:10:41.264 --> 00:10:45.065
They were all like, kind of doing a, an Atkins type, which.
00:10:45.904 --> 00:10:47.585
Can be ketogenic in some ways.
00:10:47.825 --> 00:10:50.105
And yeah, they all apparently had really bad breath.
00:10:50.134 --> 00:10:53.825
It was like a gossip column was talking about how they all had really bad breath.
00:10:54.095 --> 00:10:57.065
Cause they were just all, um, yeah.
00:10:57.424 --> 00:11:02.225
Starving themselves and work well for today's world where people don't actually see each other in person.
00:11:02.225 --> 00:11:03.125
They just take pictures.
00:11:03.154 --> 00:11:03.424
Right.
00:11:03.424 --> 00:11:05.195
So you can have bad breath, but look great.
00:11:05.294 --> 00:11:05.914
Or you're wearing
00:11:05.914 --> 00:11:07.654
a mask and it doesn't match.
00:11:08.134 --> 00:11:09.965
Well, you got to live with your own breath then that's true.
00:11:10.445 --> 00:11:10.865
Okay.
00:11:10.865 --> 00:11:14.375
So what besides epilepsy?
00:11:15.149 --> 00:11:20.610
Is Quito used with and weight loss was a really, that's a really big popular one.
00:11:21.360 --> 00:11:29.159
I think that's what you see when you see people who are advertising, like all of these, like, I don't know why I'm obsessed with keto donuts and keto bread.
00:11:30.570 --> 00:11:32.759
That's keto, ice cream, all of that stuff.
00:11:32.789 --> 00:11:33.149
I think.
00:11:34.065 --> 00:11:48.284
For people who don't want to deprive themselves while they're trying to lose weight, um, diabetes, it's been looked at metabolic syndrome, which is that sort of conglomerate of high blood sugars, high blood pressure and high cost.
00:11:48.980 --> 00:12:02.269
Um, different neurodegenerative diseases like Parkinson's and Alzheimer's, I think also it's being looked at, and then the reason why we're here, cause we're the cancer pod is it's also being studied with various
00:12:02.269 --> 00:12:03.049
cancers.
00:12:03.169 --> 00:12:03.529
Yeah.
00:12:03.769 --> 00:12:07.610
There's a few reasons it's become popular and the whole idea of the metabolic.
00:12:08.065 --> 00:12:12.445
In flexibility of the cancers, uh, various cancers has become popular.
00:12:12.445 --> 00:12:20.934
So meaning the metabolism of the cancer cells is different than the metabolism of normal cells that we've known this for a very long time, right?
00:12:20.934 --> 00:12:23.335
That the metabolism within cancer cells is different than normal cells.
00:12:23.605 --> 00:12:28.674
The problem with this whole thing is, and I want to just put this out front is there is no cancer material.
00:12:29.320 --> 00:12:31.120
As a whole, it's not like one thing.
00:12:31.120 --> 00:12:32.799
It depends on the type of cancer.
00:12:32.830 --> 00:12:35.649
And then even within the type of cancer, which subtype of cancer.
00:12:35.679 --> 00:12:42.789
So breast cancer, for example, has a different metabolic picture for each different type of breast cancer.
00:12:42.789 --> 00:12:53.830
So if it's estrogen receptor positive versus negative, if it's her two positive versus negative, the type or subtype of breast cancer will change, it's likely metabolism.
00:12:54.100 --> 00:12:55.019
So meaning when.
00:12:55.860 --> 00:13:03.659
Remember metabolism of every cell in the body is based on using either fat, amino acids or glucose as fuel.
00:13:03.720 --> 00:13:14.879
That's it, you've got three things that can be used as fuel within a cell and normal cells can be very flexible between using, for example, glucose when it's available and ketones, when there's no glucose available.
00:13:15.059 --> 00:13:17.159
The only exception to that by the way, is the liver.
00:13:17.250 --> 00:13:19.259
The liver cannot use ketones for energy.
00:13:20.460 --> 00:13:22.590
But otherwise all cells in the body can generally do that.
00:13:22.980 --> 00:13:33.269
And in some cancers like glioblastoma primary brain tumor, aggressive brain tumor, it happens to most often have a metabolic inflexibility.
00:13:33.269 --> 00:13:35.370
So it can't use those ketones.
00:13:35.370 --> 00:13:39.960
So when glucose is not around glioblastoma cells have a hard time using ketones for.
00:13:40.735 --> 00:13:51.294
So it's, it's one of those that's been well-studied and well-proven, and I think of all the cancer is glioblastoma has the most research of any cancer and probably the best hypothesis for its use to.
00:13:51.625 --> 00:13:58.705
And so when somebody would start a ketogenic diet, if they had glioblastoma, this is something they have to be on for.
00:13:59.360 --> 00:14:05.240
That's what's also being looked at is the data that we do have implies that that is true.
00:14:05.659 --> 00:14:11.029
In the case of glioblastoma, we had some early anecdotal cases that were written up.
00:14:11.419 --> 00:14:13.460
I can think of one paper in particular.
00:14:14.865 --> 00:14:24.945
The patient had glioblastoma went on a ketogenic diet, had control of the disease long story short until they couldn't do this ketogenic diet anymore because it was so restrictive and they stopped doing it.
00:14:24.945 --> 00:14:29.475
They had progression of disease and there was an assumption that, you know, this must have something to do, right.
00:14:29.475 --> 00:14:31.725
There's correlation here, but that was a case study.
00:14:31.725 --> 00:14:37.965
And there have been several trials of patients with glioblastoma who have tried ketogenic diets.
00:14:37.965 --> 00:14:43.965
And I want to say right now, the number of publications, either either nine or 10 out there, almost all of them are small.
