1
This is Ozempic, the drug that can make people lose this much weight with just one injection a week.
2
But how does it actually work?
3
Is it truly safe?
4
And what happens when people stop taking it?
5
To answer these questions, we first need to understand why losing weight is so difficult.
6
The world has a fat problem, a massive, global, decades -long problem.
7
More than a billion adults are now classified as obese, a number that has tripled since 1975.
8
So the solution should be simple, right?
9
Eat less?
10
Move more?
11
Problem solved?
12
No. Because the moment you start eating less, your body says, we are under attack.
13
Release the hunger.
14
Your metabolism slows down.
15
Your body starts treating every calorie like it's the last helicopter out of Saigon.
16
Which is why so many people lose weight and then gain it all back.
17
For decades, scientists knew the body was fighting back.
18
They just couldn't figure out how to turn that signal off.
19
Then the answer came from the last place anyone expected.
20
A lizard.
21
Introducing Dr. John Eng.
22
Eng was an endocrinologist, a doctor who treats hormone -related problems in the body at a VA hospital in the Bronx with a very unusual interest.
23
Venom.
24
More specifically, the venom of the Gila monster.
25
A large, slow, deeply unfortunate -looking lizard from the American Southwest that looks like it was assembled from leftover parts.
26
John.
27
What are you doing?
28
This thing barely eats.
29
Sometimes only a few times a year.
30
And yet, somehow, its body stays stable.
31
Maybe that is just what it does.
32
Ain't no way.
33
Something in that saliva is keeping it alive.
34
So Eng studies the lizard's venom.
35
And inside it, he finds something remarkable.
36
A compound that behaves a lot like a human hormone called GLP -1.
37
Now GLP -1 is basically the body's meal signal.
38
You eat.
39
Your gut sends a message to your brain.
40
Food arrived.
41
You can stop eating now.
42
Then it sends another message to your pancreas.
43
Sugar incoming.
44
Release insulin.
45
When that signal works properly, the body handles food without much drama.
46
When it does not, everything starts getting messier.
47
Appetite?
48
Insulin response?
49
Blood sugar?
50
Weight?
51
The whole system begins slipping out of balance.
52
And Eng realizes something huge.
53
What if you could replace that failing signal?
54
That idea eventually leads to the first GLP -1 drug.
55
For the first time, medicine is not just treating the consequences of metabolic disease.
56
It is trying to restore one of the signals behind it.
57
But there is one problem.
58
The drug is clunky.
59
Patients need to inject it twice a day.
60
The effect fades quickly, so most of the world shrugs and moves on.
61
Except for one company watching from Denmark.
62
They look at the same drug everyone else dismisses and see something different.
63
Introducing Novo Nordisk.
64
They are a Danish company that has spent 50 years as the backbone of diabetic care.
65
Insulin is their main solution.
66
But it has limits.
67
Insulin helps manage blood sugar and keep patients alive.
68
Yet it does not fix the deeper signaling problem underneath where GLP -1 might.
69
So Novo sets itself a brutal goal.
70
Let's make it last for a week.
71
That is the target.
72
The molecule dissolves in minutes.
73
Two minutes.
74
How do you build a weekly drug out of something that dissolves quickly?
75
That is the job.
76
And this is where the nightmare begins.
77
The moment natural GLP -1 enters the bloodstream, the body breaks it down almost immediately.
78
So they change the molecular structure.
79
Tweaking it for stability?
80
It loses power.
81
Making it more powerful, the body destroys it faster.
82
Again and again and again.
83
216 versions.
84
None good enough.
85
But now it's a good enough time for a quick ad break.
86
You know what's weird?
87
I'll spend three hours researching whether a $20 gadget is worth buying, but the moment I need to book a doctor's appointment, suddenly my brain goes, eh, tomorrow.
88
Because then you have to call, wait on hold, play phone tag, and by the time someone finally answers, the next appointment is sometime after the heat death of the universe.
89
That's why I've started using ZocDoc.
90
It lets you search and compare local in -network doctors, read reviews from real patients, check actual appointment availability, and book online in just a few clicks.
91
Appointments are often available within 24 to 72 hours, sometimes even the same day.
92
And it's completely free to use.
93
So if you've been putting off making that appointment like I used to.
94
Click the link in the description or head to zocdoc .com slash crayoncapital.
95
Seriously, it's a small click that makes taking care of your health a whole lot easier?
96
Okay, back to Novo.
97
The costs keep growing and the confidence shrinking.
98
The problem is starting to look unsolvable.
99
But then, what if we attach a fatty acid chain to it?
100
A fatty acid?
101
Why?
102
Okay, think of the bloodstream like a nightclub.
103
The body's enzymes are the bouncers.
104
Anything foreign gets spotted and thrown out.
105
Our drug?
106
Kicked out in minutes.
107
But albumin is a protein that naturally lives in the blood.
108
The VIP who's never questioned?
109
And the only thing that gets albumin's attention?
110
Fatty acids.
111
It's basically albumin's magnet.
112
So if we attach a fatty acid to our drug, albumin pulls it in like a plus one.
113
Suddenly it's not a stranger anymore.
114
It's rolling in with the VIP.
115
Bouncers wave it through.
116
It stays in the system for a week.
117
At last, on the 217 attempts, they have it.
118
A lab -engineered version of the body's own signal, built to last 7 days instead of minutes.
119
In 2017, the FDA approved it for type 2 diabetes.
120
And they name it, Ozempic.
121
It is a quiet launch.
122
No headlines.
123
Just another diabetes drug entering a crowded market.
124
But doctors start noticing something strange.
125
Did you change these patients' diets?
126
Tell them to exercise or anything?
127
Hmm, I don't think I did.
128
Why, is something wrong?
129
No, it's just they lost weight.
130
Like, all of them.
131
For most companies, this would be the dream.
132
A diabetes drug that also makes people lose weight?
133
That is a jackpot, not a side effect.
134
But inside Novo, nobody is celebrating too loudly yet.
135
Because weight loss drugs had a history.
136
A very ugly one.
137
The results were disappointing, dangerous, or both.
138
Fen -Fen pulled in 1997?
139
Meridia pulled in 2010?
140
By the 2010s, much of medicine had reached an uncomfortable conclusion.
141
Maybe obesity was too complicated for a drug to solve.
142
But Novo doesn't flinch.
143
They launch a major clinical trial to answer one question.
144
Can this drug cause major weight loss in people who do not even have diabetes?
145
Hi, I'm calling from Novo.
146
I just wanted to check if the trial data has been reviewed yet.
147
Yes.
148
We finished going through it this morning.
149
Patients lost an average of 15 % of their body weight.
150
Some were closer to 20.
151
Sorry, what?
152
15 %?
153
Average.
154
Across the trial.
155
Before this, the best FDA -approved weight loss drugs usually delivered around 5 to 8 percent weight loss on average.
156
That was considered strong.
157
This is not a slightly better obesity drug.
158
This is in a completely different league.
159
A weekly injection was now producing numbers people used to associate with surgery.
160
So researchers and regulators check the data again and again.
161
The methodology holds, the results hold.
162
The weight loss is real.
163
So by 2021, the FDA approved a higher dose version specifically for obesity, WEGAV.
164
And just like that, the drug splits into two identities.
165
Ozempic for diabetes, the stronger dose for weight loss.
166
That is when the story leaves medicine and enters culture.
167
Doctors start getting flooded with questions.
168
Patients start asking for it by name
169
because suddenly celebrities are looking smaller influencers are whispering about it and search traffic is exploding
170
ozembek goes viral demand surges sales explode where by 2024 the
171
drugs generated 26 billion dollars in revenue novo nordisk becomes one of the biggest pharmaceutical stories on earth
172
But there is one problem.
173
They cannot make enough.
174
In 2022, the FDA placed Ozempic and Wegevee on its shortage list.
175
And this is where the story gets ugly.
176
Good afternoon.
177
Welcome to Crayon Pharmacy?
178
Picking up a prescription?
179
Yes, Ozempic.
180
I see it here.
181
Just so you know, your insurance didn't cover it, so this would be out of pocket today.
182
How much?
183
Total is $1 ,200.
184
Fine.
185
Sorry, you have Ozempic?
186
I'm here for another prescription.
187
But I've been trying to get a refill for weeks.
188
I see your refill request.
189
Your insurance covered order is still pending.
190
We're waiting on allocated stock for covered prescriptions.
191
But there's one right there.
192
This one has already been processed as a cash pay prescription, so if I can pay cash, I can get it today?
193
I have type 2 diabetes.
194
I've been on this for two years.
195
I really need this.
196
Is there a problem?
197
You're all set.
198
Thank you for waiting.
199
Your medication and receipt are in the bag.
200
Have a wonderful day.
201
regarding your situation we can fill the temporary medication your doctor
202
sent in you've got to be kidding me I'm sorry for the inconvenience
203
but until your insurance covered refill clears there's nothing I can release today except the temporary medication
204
and that is the dangerous part
205
if the official system will not give people the drug someone else in the gray market will.
206
Clinics offering the alternatives at a fraction of the market price.
207
$200 a month instead of $1 ,200.
208
No wait list.
209
No insurance battle.
210
A quick online form and a vial arrives at your door.
211
It sounded perfect for desperate patients.
212
Until it wasn't.
213
By 2023, Faco Zempic has entered the American drug supply chain, manufactured to look real, distributed through channels that bypass safety checks,
214
sold into a market desperate for the miracle.
215
Some patients received the wrong dose or the wrong substance, leading to some being hospitalized.
216
But even the real drug wasn't perfect.
217
Nausea.
218
Vomiting.
219
Sometimes bad enough that patients quit in the first month.
220
Doctors started noticing muscle loss alongside the fat.
221
And the worst part?
222
I stopped taking it six months ago.
223
I've gained almost everything back.
224
That's not uncommon.
225
So is this a cure or a subscription?
226
The drug didn't cure anything.
227
It managed it.
228
Stopped paying.
229
The hunger comes back.
230
The body remembers.
231
But we had been here before.
232
Novo Nordisk failed 216 attempts.
233
Every dead end eventually wasn't.
234
So the scientists went back to work.
235
Next generation drugs already in trials, Preserving muscle, lasting a month instead of a week.
236
Showing signals in alcohol cravings, opioid addiction, even brain disease.
237
What started in a lizard's venom was turning out to be something much larger.
238
By 2025, the chaos had settled.
239
Supply caught up.
240
The gray market collapsed.
241
And quietly, without anyone declaring it, the conversation had moved on.
242
If hunger could be rewritten, what else could?
243
As Brian Johnson said, we might be the first generation, that doesn't die.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
