GLP-1 drugs are everywhere.
2
GLP-1.
3
GLP-1s.
4
People scramble to get their hands on GLP-1 drugs.
5
Today we're going to talk about the psychiatric effects of GLP-1 agonists or medications like Ozempic.
6
And if you're thinking about taking a GLP-1 agonist, or if you're taking a GLP-1 agonist, what you should be aware of,
7
because things are a little bit complicated.
8
Some studies will show improvements in binge eating, some studies will show increases in anorexia, Some studies will show improvements in moods.
9
Some studies will show triggering of depression.
10
And so what's going on here?
11
And it turns out that actually all of that is true.
12
And that's why we need to dive into it with a little bit more detail.
13
So we're going to start off by doing a quick review of glucagon-like peptide and what its role is in the body.
14
So the first thing to understand is that GLP is a hormone.
15
So the hormones are chemical signals that travel everywhere in your body, everywhere that blood exists.
16
Okay, so the first thing to understand about hormones is that they have differential effects on different parts of your body.
17
So let's use a simple example of hormone, testosterone.
18
So testosterone has differential effects depending on the tissue that it reaches.
19
So the skin cells on the top of my head will make me bald.
20
The skin cells over here will make me actually grow hair.
21
The skin cells on my back will also start to grow hair.
22
So it causes a differential pattern of hair growth depending on the target tissue.
23
When testosterone travels to my brain, it'll increase my sense of protectiveness, maybe some degree of aggression, some degree of competitiveness.
24
When it travels down to my scrotum and testicles, it stimulates sperm production.
25
And so depending on where a hormone travels in the body, it will have a differential effect.
26
And when it comes to GLP-1 agonists, this will explain a lot of the contradictory information.
27
So next thing we have to understand about GLPs is what is the role of glucagon-like peptide?
28
Why does the body secrete it?
29
What is its job?
30
So GLP is a satiety hormone, okay?
31
So satiety is to feel sated, to feel satisfied.
32
So basically when we eat something, our stomach stretches, glucose gets entered into our bloodstream.
33
And so our body has these two modes.
34
It has a hungry mode and it has a no longer hungry or satisfied mode.
35
And GLP is one of the key signals that tells our body we are satisfied.
36
GLP also works in concert with insulin.
37
So you can sort of think about it like in the same way that you get a food coma from insulin, GLP-1 will signal to parts of your brain that we have had enough to eat.
38
I keep seeing comments, Dr. K, how do I apply this to a situation in my life?
39
That's literally why we created a coaching program.
40
Our coaches are certified on an evidence-based curriculum designed to help you get unstuck.
41
This involves analyzing your patterns, increasing your understanding, and working with you week to week to help you develop a plan to create lasting change.
42
So if y'all are interested, check out the link in the description below.
43
If we look at insulin, insulin is focused primarily on glucose metabolism.
44
So it regulates our blood sugar, okay?
45
But GLP is not related to blood sugar, but it is related to other parts of satiety.
46
So GLP travels to this part of our brain called the ventral tegmental area, which is where our dopaminergic reward circuitry is.
47
So when we have a craving, that comes from our dopaminergic reward circuitry, right?
48
Like I wanna eat french fries.
49
And then I eat french fries and then it feels pleasurable.
50
So eating food is tied with pleasure.
51
Eating fatty food, having intense cravings for sugary food, all of those are tied to pleasure.
52
And I don't know if you guys have kind of experienced this, but like, hopefully.
53
You know, you can eat a cookie and it tastes really good then you eat a second one, you eat a third one, you eat a fourth one, you eat a fifth one.
54
And if you look at the volume of cookies you're eating, they're actually pretty small, right?
55
Like you can eat five cookies.
56
And it's not like the same quantity of food.
57
It's not the same volume of food as let's say like a big salad that is like low calories, right?
58
But as each subsequent cookie you eat gives you a reduction in your craving, and then your pleasure starts to kind to go down.
59
A lot of that reduction in your pleasure is mediated by GLP.
60
So GLP travels up to your brain and actually inhibits the pleasure that you get from eating foods.
61
That same part of your brain, the ventral tegmental area or nucleus accumbens, is also where our cravings come from.
62
So I don't know if this kind of makes sense.
63
The more you eat, the less you crave eating, unless you've got something like a binge eating disorder, right?
64
So that kind of makes sense.
65
more pleasure you have.
66
So I have cravings high, pleasure low.
67
And then as I eat, cravings go down and pleasure goes up.
68
And the chemical signal to mediate that shift is a GLP-1.
69
So the GLPs basically reduce our cravings and increase our sense of satiety.
70
So now let's talk about GLPs and addictions, because if we're reducing our cravings and blunting our pleasure, then it should have an impact on addictions,
71
which is absolutely what we see.
72
This is a study that was used AI to analyze people talking on the internet
73
and basically found that people were reporting when they started GLP-1 agonist like Ozempic that it affects their substance intake.
74
So it reduces their alcohol intake, reduces their caffeine intake, reduces their nicotine intake, seems to have not a huge effect on cannabis.
75
And then in terms of behavioral addiction, seems to reduce compulsive shopping, impulsive shopping.
76
But according to some of these reports, may actually enhance pornography usage.
77
So people become potentially more addicted to pornography or use pornography more when they are on GLPs.
78
So what's going on here?
79
So in order to understand how GLPs affect addictions, we have to understand a little bit more about how they affect the dopaminergic circuitry, okay?
80
So this gets a bit complicated.
81
So this is the way that your dopamine normally works, okay?
82
So we have some level of dopamine that just fluctuates throughout our day.
83
I take a sip of water, mmm, that water's tasty.
84
I get a little bit of dopamine, okay?
85
And then there are times where I'm like a little bit bored, oh my god, this is boring, like this guy is just like rambling on about dopamine, he's He's talking about science.
86
Oh my God, that's so boring.
87
So we get a dip in our dopamine.
88
So our dopamine just kind of goes up and down throughout the day.
89
And then what happens is we sometimes get something that is addictive.
90
So I eat a donut or I play a video game or I use cocaine.
91
And in those three cases, right, or sometimes all three all at once, I get a spike of dopamine.
92
So the way that GLPs work is by capping the dopaminergic signal that your brain can get.
93
So it doesn't affect our day-to-day dopaminergic stuff, but if we do something that induces a spike of dopamine,
94
it kind of caps that, okay?
95
So the way that you can think about it is like, it doesn't affect the basic speed of our car, it just lowers the top speed that my car is capable of going.
96
I can hit 100 kilometers, but I can't hit 120 or 140 or 150.
97
Now, the interesting thing is that it is the high spikes that make us addicted to things, okay?
98
So it's really hard to get addicted to something that has a low dopaminergic signal.
99
So the things that are the most addictive are the things that give us the biggest spikes.
100
So when my friend says, hey, Dr. K, it's great to see you.
101
Like, are you having fun at the party?
102
I'm like, yeah, man, I'm having fun.
103
He's like, you want to go into the bathroom and do some c*?
104
And I'm like, sure, I'll give it a shot.
105
Wow, that's amazing.
106
So when we get a high spike of dopamine, that is what triggers neuronal rewiring.
107
So we can look at this in other mechanisms like loot boxes.
108
Why are loot boxes so addictive?
109
Because the spike in dopamine that they give us is way higher because most of the time we get nothing.
110
Occasionally we get a big spike and then we're like, oh my God, I want that high again.
111
This is why people who play the lottery and lose lots of money over the lottery
112
will still continue to play it because that spike of winning keeps us coming back.
113
So now this is something that's like pretty cool because the GLP-1, since it prevents the spike, it prevents us from getting addicted to things.
114
It's not that simple, but that's basically the mechanism that it's blunting, which is why we see, it's really fascinating, reductions in a lot of addictive behaviors, okay?
115
And this is what's kind of interesting about it.
116
So now we're going to tunnel down into specifically alcohol use.
117
So here's a study that's looking at semaglutide or ozempic on alcohol use.
118
And what we find is that people who are on GLP-1s, it doesn't reduce the number of days that they drink.
119
Okay, so if I normally have drinks three days a week, I go to happy hour on Thursday, go to happy hour on Friday, have a wine night on Saturday.
120
Once I start my GLP-1, that doesn't change.
121
I still drink Thursday, Friday, and Saturday.
122
But what it changes is how much I drink.
123
So if you measure the average alcohol concentration in the blood before
124
and after some of the what you find is that the alcohol concentration is way lower.
125
The number of drinks that I have actually drops quite a bit.
126
I still feel like drinking, right?
127
Oh, like I'll have a glass of wine.
128
But whereas I used to have like two, three, four glasses of wine, now I'm having like one and a half to two.
129
And if we kind of think about it, once we understand the neurochemistry, it sort of makes sense because it's reducing my craving.
130
It is blunting the pleasure that I get from alcohol.
131
So I can enjoy a glass of wine with dinner, but then after you have that first glass, you're like, man, like top me up.
132
Give me a hefty pour, right?
133
After you have that second drink, you're like, fill it up all the way, baby.
134
Like, let's go.
135
As you start to drink a little bit, you wanna drink a little bit more.
136
As you start to eat one potato chip, you're like, man, that potato chip was really good.
137
Let me have a second.
138
Let me have a third.
139
Let me have a fourth.
140
That's what it blunts, right?
141
Because it caps that dopamine.
142
So it appears like we've got pretty decent evidence
143
that it improves a lot of addictions alcohol at the top of the list, maybe caffeine, maybe nicotine, maybe impulsive shopping, maybe binge eating for sure,
144
but it may not have much of an effect on cannabis and may actually be harmful when it comes to pornography.
145
Now remember that GLPs affect all the different parts of our brain.
146
And so when it affects the emotional parts of the brain, it appears that it leads to a lot of mood dysregulation that is not good.
147
So it seems to increase feelings of depression, seems to blunt our capacity to experience pleasure.
148
And this is what some people call kind of the ozempic personality.
149
This is when people are on semaglutide, like they just don't feel like doing stuff.
150
Stuff doesn't really feel super fun to them.
151
And that kind of makes sense.
152
So it causes some anhedonia.
153
So anhedonia is the inability to experience pleasure.
154
It's one of the hallmarks of a depressive episode.
155
And when people are on semaglutide, we can see how it can cause anhedonia because it is capping our dopaminergic response, right?
156
So we're not feeling really excited about stuff.
157
Like sure, it caps the cocaine response and the alcohol response, but maybe it's also capping the birthday party response.
158
And since those spikes of dopamine are what encourage our behavior, right?
159
Once I get a loot box, I want to buy another one.
160
Once I go out and I have a blast, how was this party on Saturday night?
161
Oh my God, bro.
162
It was completely awesome.
163
Some people were doing in the bathroom.
164
I steered clear of it, but I still had a great time.
165
But if I'm blunting my ability to have a great time at a party, that'll then shape my motivation.
166
And over time, the Ozempic personality seems to kind of like contract people's sphere of what they do.
167
So there's evidence that it increases feelings of depression.
168
One study found that it increased as much as 195%.
169
So the risk of depression skyrockets, right?
170
So that's almost a twofold risk.
171
And it also appears to increase suicidality by over 100% according to this one study.
172
And so doctors for the past several years have been noticing that when they start their patients on GLP-1s, that it seems to be increasing the risk of depression,
173
can cause relapses of depression.
174
And what's even the scariest thing is that for people who have had no history of depression,
175
seems to drastically increase the risk that they will develop depression for the first time.
176
But then there are some studies, especially things called meta-analyses.
177
So this is when we pool together data from lots of different studies to see
178
if there's something that kind of floats to the surface.
179
So here's an example of a meta-analysis that basically found that there's no increased risk of depression.
180
So like what's going on, right?
181
So on the one hand, you have doctors who are prescribing this medication, who are seeing people relapse onto depression or having a resurgence of their depression.
182
You're seeing people have new onset depression, but then you have some of these big trials that are showing actually there seems to be no difference.
183
It doesn't actually increase risk.
184
So what's the deal?
185
And this is where we get to a really fascinating, I think for me, key finding about GLPs,
186
which is that the kind of person who takes it determines how healthy or unhealthy it is.
187
So here's a study that found something really interesting.
188
For people who were obese and took a GLP-1, it did not increase their risk of depression.
189
But for people who were at a normal or healthy weight, and if they took a GLP-1,
190
there is a greater chance that it increased their risk of depression.
191
And this is where we have to get to some like really basic important stuff about medicine.
192
See, anytime I prescribe a medication as a doctor, there's a risk benefit, which is like, duh, but let's understand something about depression.
193
So let's say I'm morbidly obese.
194
I have a BMI of 30.
195
When I need a CAT scan, I have to go to the, literally, I've had patients who have this, I'm like 600 pounds or 700 pounds,
196
and I don't fit in the CAT scan at Massachusetts General Hospital.
197
So I have to get transported by ambulance to the zoo because they have a CAT scanner that will work on me.
198
Imagine that that is what my life is like.
199
Now imagine what is the impact on my mood
200
if I am very overweight and I have to use the zoo's CAT scanner, right?
201
So shaming, incredibly depressing.
202
Now let's say I take semaglutide.
203
and then what happens is I lose, let's say, 100 pounds, 200 pounds, 300 pounds, what impact will that have on my mood?
204
So what we start to see, this is really important, is weight loss and a reduction in obesity has a positive impact,
205
a huge positive impact on depression.
206
That's not just because of the shame of the Zoo Cat Scanner, that's because we don't realize that adipose tissue, fat tissue, is hormonally active.
207
So the greater my fat tissue, the more insulin resistance I have, the more inflammation I have.
208
There are many negative mental health benefits of being at an unhealthy weight, let alone the psychological shame and all that kind of stuff.
209
So when we're talking about a risk benefit, being able to lose 100 pounds, being able to go outside and go to the beach and things like that,
210
that will have such a positive impact on my mental health that even if from a chemical sense, it's messing with my affect regulation centers,
211
the gain that I get from the weight loss for my mental health will outweigh
212
or balance the risk of messing up my emotional regulation centers in my amygdala and my limbic system.
213
Whereas if I am at a healthy weight and I just start some agglutide,
214
I'm not getting some of those benefits from the weight loss for my shame
215
and being able to go to the beach and things like that, because I can already do that.
216
I already get sent to an imaging center instead of the zoo when I need a cat scan.
217
So this is why I think it's really important to like that, and this is what the studies show, is that there is a differential effect of GLPs on people's mental health.
218
And the more overweight you are, the more helpful a GLP is.
219
And the less overweight you are, the more potentially harmful a GLP is.
220
And the best place that we see that is actually when we talk about eating disorders.
221
So the first thing, remember, is that GLPs go to the ventral tegmental area.
222
They blunt the dopaminergic pleasurable response.
223
So no surprise that people with binge eating disorders, right, when I can't stop myself and I'll eat 6,000 calories in a sitting.
224
And if we think about what's driving that, it's the pleasure, It's the dopamine.
225
I feel addicted.
226
I can't stop.
227
And when we give people GLPs, it seems like they really blunt binge eating disorders.
228
So people's binge eating goes way down.
229
Good job.
230
But if we look at other kinds of eating disorders that are not reward based,
231
are not addictive, are not dopaminergic, anorexia is at the top of the list.
232
So the neurochemistry of anorexia is not related to reward, right?
233
It's not like people who are anorexic, they actually feel awful.
234
They feel really bad.
235
They're not, I've had patients who are hospitalized with anorexia, who we have to start, we have to put tube, we have to start tube feeds.
236
We have to sometimes in really scary situations, strap them, actually physically restrain them to get calories inside their body
237
because they're so malnourished that their heart is starting to have arrhythmias.
238
The interesting thing is when someone is in that bed getting IV fluid or getting nasogastric tube feeds,
239
they're not high, right?
240
They're not like pleasurable.
241
This isn't fun for them.
242
Their suffering is profound.
243
Their suffering is intense.
244
And even if you talk to people with anorexia, what you'll find is that like the majority of their day is like suffering.
245
Like they're like, they have all these cravings.
246
They really want to eat their fucking body wants to eat something, man.
247
Like, Oh my God, I want to eat something.
248
The cravings are so hard.
249
I'm with my friends and my friend brought a peanut butter, peanut butter and crackers and, and like a girl dinner plate with like fruit and peanut butter and crackers.
250
And this like triggered me so hard.
251
Their baseline experience is suffering.
252
An anorexia conversation for a day is all about control trying to exert control trying to hammer your body
253
and the world around you into complying with your will
254
that has nothing to do with dopamine and
255
so what we're starting to see that's really scary is
256
that glp1s they may help with binge eating disorders
257
but they are actually making anorexia and restrictive eating disorders potentially way worse and they are potentially causing a trigger,
258
someone who didn't have an eating disorder, to have eating disorders.
259
So here's what's really scary.
260
One of the risk factors for causing an eating disorder is weight loss.
261
So if you are someone who has certain psychological vulnerabilities, especially around body image, right?
262
So if you're someone who is at a healthy weight, and you have a lot of body image issues because you spend a lot of time on the gram,
263
on TikTok, on seeing all these people who have filtered faces and now you start to feel a little bit vulnerable.
264
You go on dating apps, but people swipe left.
265
Oh my God, right?
266
This is happening all over the place.
267
So we have psychological vulnerabilities.
268
In people with psychological vulnerabilities who lose weight, this can actually trigger an eating disorder, okay?
269
So there's something called atypical anorexia nervosa, which has all the features of anorexia.
270
So restricted eating, body image issues, but they're actually at a normal weight.
271
So one of the key factors of diagnosing anorexia is you have to be at an unhealthy weight.
272
That's one of the diagnostic criteria.
273
But there are some people who have atypical anorexia.
274
They have the mind of an anorexic and the body of someone who is at a regular BMI or a healthy BMI.
275
And even as much as a 5% weight loss can trigger atypical anorexia.
276
So we can trigger eating disorders if we actually lose weight.
277
And here's what's really fascinating.
278
There are some studies that show that patients with binge eating disorders who go through cognitive behavioral therapy, the more weight they lose,
279
there's a binge eating disorder, so they're usually at a normal weight or potentially even overweight.
280
The more weight they lose, the greater their risk is of developing something like anorexia.
281
It's insane.
282
So like if I go through cognitive behavioral therapy and I lose 50 pounds, my risk of anorexia is higher than if I lose 25 pounds, right?
283
So there's something about the extremity, I don't know, the severity of like the rigidity of anorexic thinking where the more you lose weight, the more it kind of turns on.
284
And this is what we're seeing with GLPs is it seems to exacerbate this risk.
285
And this is where people are sort of seeing the like the ozempic face, right?
286
And the ozempic face is like kind of shrunken.
287
And there are very like severe cases, case reports of people who are able to manage 400 to 600 calories a day are getting dehydrated with using semaglutide.
288
And I want y'all to kind of think about this for a second, okay?
289
Because let's say I'm an anorexic and I want to lose as much weight as possible.
290
I hate the fact, I look at my face in the mirror and I think that I'm obese.
291
So in my body, there's a war, which is what anorexics suffer with, okay?
292
There's a war between like my liver telling me, hey, we're out of calories, like we need food.
293
And so there's strong craving signals that are being sent to my brain.
294
We are starving, bro.
295
Give us some food.
296
And that fights against my control.
297
So I have pro eating signals and anti eating signals.
298
And how does a GLP-1 work?
299
Agonist work?
300
It reduces my cravings.
301
It reduces, it's a GLP-1 agonist.
302
It tricks my brain into thinking we just ate.
303
So now that I've tricked my brain into thinking that we just ate, my capacity to restrict my calories actually increases.
304
So at the end of the day, what is the impact of GLPs on your mental health?
305
We kind of don't know for sure.
306
Should you take a GLP-1?
307
I would say this is why we say talk to your doctor.
308
This is not just medical, legal, cover your ass.
309
This is why what we're seeing with GLPs-1, GLP-1s, it is a highly individual decision based on your risk factors?
310
Do you have a lot of health benefit to gain from losing weight?
311
Or are you trying to do this for cosmetic reasons, right?
312
Are you struggling with certain addictions?
313
Do you need to cut down on your alcohol?
314
But is it porn addiction?
315
And lastly, if you have a history of mental illness or even don't have a history of mental illness,
316
you should be on the lookout for things like a rise in depression or even spike in suicidality.
317
So potentially amazing drug, but to be used with caution.

발음의 함정 주의하기

영상에서 발음이 어려운 단어와 발음 패턴을 알아보세요. "glucagon-like peptide"는 [글루카곤-라익 펩타이드]로 발음하되, "glucagon"의 'c'는 [k]가 아니라 [g]로 발음하는 것이 중요합니다. "dopaminergic"는 [도파미너지크]로 발음하며, 중간의 'min' 부분을 빠르게 발음하지 않고 명확히 구분해야 합니다. "ventral tegmental area"는 [벤트럴 테그멘탈 에어리어]로 발음하되, 'tegmental'의 'g'는 [g]가 아니라 [dʒ]로 발음하는 것이 일반적입니다. 이 단어들은 영어 쉐도잉 연습을 할 때 정확한 발음을 연습하여 자연스러운 회화를 구사할 수 있도록 합니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
