Практика Shadowing: Peptides Are Insane - Изучайте разговорный английский по видео
Создание урока...
1
Peptides are kind of insane, and right now, they're everywhere.
2
You cannot open social media without seeing a new peptide that'll transform your body.
3
There's millions of people that are taking peptides, and it's radically improved their health.
4
What if I told you that there was a peptide that tells your brain to grow new neurons?
5
If you are not on peptides, I want to know why you are not on peptide.
6
I am now on five different peptides.
7
You're telling me I'm going to be able to inject myself with a Zenpec to lose the fat, and then inject myself with something else to keep the muscle? it's wild usually big claims like
8
that trigger my detector right away and they did in this case too
9
but the thing is peptides actually do work at least some
10
of them do for the first time ever people can simply take a peptide like ozempic
11
and fat seems to melt off like a lot this is
12
what weight loss typically looks like over a year of diet
13
and exercise and this is what weight loss typically looks like over a year of diet
14
and exercise plus a glp1 peptide people have been struggling with fat loss for decades.
15
So this is a huge shift and naturally it raises the question if peptides can do that, what else can they do?
16
So I went down the rabbit hole.
17
I pulled together all the studies I could find on peptides, the good and the bad.
18
In this video, I want us to take these peptides together, see what happens inside our bodies and figure out which ones are actually worth the hype.
19
At this point, I'm sure you've probably heard about peptides, but you may not know what they actually do a lot of people think of them like mini steroids
20
but chemically no they're nothing like testosterone they're also not stimulants like the caffeine in your coffee they're not vitamins
21
or minerals or anything like that biochemically they're actually most similar to protein
22
if you take a scoop of protein powder
23
and zoom all the way in the individual protein molecules look
24
like this long tangled chains of amino acids you get a peptide
25
if you untangle those long chains and cut them down into shorter chains of amino acids.
26
There are about 20 amino acids in total that can be linked in different combinations to make millions of different peptides.
27
But we can simplify all that down to the three kinds of peptides that health and fitness people really care about.
28
First, the fat loss peptides.
29
This is where most of the mainstream hype is coming from.
30
These are the GLP -1 peptides like Ozempic.
31
Second, the injury healing peptides like BPC -157, also known as the Wolverine peptides,
32
and third, the anti -aging peptides that claim to help you stay fitter, healthier, and younger looking.
33
Right now, one in every eight U .S adults say that they use fat loss peptides,
34
and tens of millions of people are taking fat loss peptides right now across the globe.
35
Obviously, this has become a really lucrative business, which is why I want to say up front that I'm not sponsored by any peptide companies.
36
I do have a degree in biochemistry, and I've published peer -reviewed studies on muscle growth, and I'll be fact -checking this video with researchers and medical doctors to make sure it's as unbiased as possible.
37
Easily the most famous fat loss peptide is this one.
38
It's called semaglutide.
39
It's a big GLP -1 peptide sold under the brand names Ozempic and Wegovy.
40
To take semaglutide, you usually inject it because if you swallow it, it gets destroyed by the acid in your stomach.
41
There is an oral version, but it's still degraded in the stomach, so you need a higher dose and special technology to help it get absorbed.
42
Surprisingly, the oral version seems to be getting pretty close to the injectable version.
43
After you inject semaglutide into a layer of fat, the peptide moves into the surrounding blood vessels and travels to three places, your pancreas, your stomach, and your brain,
44
where it activates GLP -1 receptors.
45
That tells your pancreas to stabilize your blood sugar, your stomach to slow down its emptying, and your brain to stop sending so many hunger signals.
46
Those three effects create one very simple, yet very powerful super effect.
47
You feel less hungry.
48
Unlike pretty much every other fat loss supplement, semaglutide works in a pretty unique way.
49
It doesn't claim to burn more fat.
50
It also doesn't claim to boost your metabolism.
51
Instead, what it does is it simply lowers your appetite.
52
So you just eat less calories without really noticing it.
53
And that really works.
54
Because back in 2018, right before the peptide hype started to take off, 2 ,000 people volunteered to take semaglutide for the first time.
55
But here's the thing.
56
The researchers only gave some of the subjects real semaglutide.
57
They gave the other subjects a fake placebo that looked like semaglutide, but it didn't have any actual semaglutide in it.
58
None of the subjects knew whether they were taking the real semaglutide or the fake placebo semaglutide, and all the subjects were told to exercise and given dietary counseling.
59
Everyone's average weight was 232 pounds on day one.
60
The group taking semaglutide lost 34 pounds in 16 months on average,
61
but the group taking the fake placebo semaglutide only lost six pounds.
62
That's 34 pounds of weight loss versus six pounds of weight loss, with the only difference being a single peptide.
63
But that was 2018.
64
These days there are newer peptides that honestly kind of wipe the floor with Ozempic.
65
For example, compared to semaglutide's 15 % weight loss, a newer peptide called terzepatide caused 23 % weight loss in a similar time frame.
66
And retitrutide just passed through phase 3 clinical trials caused 28 % weight loss.
67
That means if you started at 250 pounds and took retitrutide for about a year and a half, you'd be expected to lose around 71 pounds.
68
The reason they work so well is that semaglutide only activates one receptor, GLP -1, but terzepatide activates two receptors, GLP -1 and GIP.
69
Reditrutide activates three, so your hunger gets even more blunted and there may be a metabolic effect too.
70
The thing is, these fat loss peptides clearly do work, but are there long -term health issues?
71
Are they even safe?
72
right hey buddy what's up man you hear me yeah yeah can hear you loud and clear
73
so you prescribe weight loss peptides to patients right yeah uh i've been fully board certified since 2014
74
and on so i don't think there's really any doubt at this point
75
that they work right yeah they are the most effective, non -surgical way for weight loss, yes.
76
Would you say that there's any doubt about whether they're safe or not?
77
No, there doesn't seem to be any big smoking gun.
78
There are some potential very rare things
79
that may not show up in a randomized controlled trial where
80
you just don't have enough people to see some of these rare things.
81
They're extremely safe, especially in the indicated population.
82
In your clinical practice, have you run into any issues with patients
83
or do most people seem to tolerate them pretty well by
84
far the most common side effect you see in the trials
85
and what we see clinically is nausea
86
and vomiting at the severe level high in the beginning
87
when you start the medicine but over time the nausea just goes down the other things
88
that we see constipation things get slower in the gi tract
89
and that actually doesn't go away over time the constipation stays constant
90
but other weird side effects people feeling like they have uti
91
i've had some patients with developing gallstones i haven't had any patients with gallbladder attacks
92
but you see it once in a while
93
but that's still relatively rare as well for what it's worth of the three weight loss peptides
94
that i've focused on semaglutide and trisepatide have fda health canada
95
and european medicines agencies approval retitrutide is just now getting through phase three clinical trial
96
so it doesn't have approval yet but based on what i've seen also seems to be tolerated pretty well overall.
97
Yeah, very similar.
98
Maybe a slight increase risk of nausea, vomiting, and a few other things.
99
But really, until you do head -to -head, you won't know for sure.
100
But it looks pretty similar.
101
These peptides do have a dark side, though.
102
This January at the gym, a lot of people noticed that there wasn't the same New Year's rush as usual.
103
I think that could be
104
because a lot of people who set New Year's resolutions to
105
lose weight this year simply just started taking a peptide instead of exercising, which sucks if true because exercise has mental health benefits
106
that you simply can't replace and you will lose a lot of muscle if you take one of these peptides without lifting.
107
In fact, without weightlifting and proper protein intake, about 40 % of the weight lost on the GLP -1 peptide is lean mass.
108
That's almost certainly not due to the peptide itself, but simply the fact that people are just losing a lot of weight without eating enough protein or training hard enough.
109
I do think a lot of people using GLP -1s do know about the risk of muscle loss though, because more people are using protein powder now than ever before
110
which sounds great in theory
111
but in some places it seems to be leading to protein shortages
112
which may be causing the price of protein powder to skyrocket much more concerning is the fact
113
that you technically need a prescription to get a glp1 peptide
114
but a lot of people either won't qualify
115
or don't want to get access through their doctor as a
116
result swaths of people are buying them from black market
117
and gray market sources online where there's often zero quality control
118
that ease of access means that now they're being used by already lean, healthy people who are trying to get even thinner,
119
which could further shift society's expectations about what a healthy or desirable body should look like.
120
But to me, that's different than overweight people using them as medicine to try to help them get down to a healthier body weight.
121
As someone who prescribes these medications to people, you'll often hear it's cheating, it's taking a shortcut.
122
Do you see it as a shortcut?
123
As someone who has to take a few medicines for my own diseases that I have, I have hypothyroidism, Hashimoto's, I would think of it similar to like put the fork down
124
and start eating a DASH -like diet and do exercise for hypertension.
125
Nobody shames anybody for taking an anti -hypertensive or tells them it's a shortcut.
126
Obesity has biological drivers in it that we can't just necessarily out discipline or out willpower.
127
And so it
128
goes
129
and hits the receptors in the brain to basically not have
130
those same biological drivers anymore kind of evens the playing field
131
so i don't see it like a shortcut at all yeah
132
i think people almost like hate on shortcuts a little bit
133
too much too right like to me there's a fine line between like taking a shortcut
134
and just like working smarter if you can get the same outcome
135
for like less torture on yourself why make it harder on
136
yourself than it needs to be right there is a slippery
137
slope there where you're just like always looking for the easy way out
138
but like at the same time you know i don't think it's
139
so black and white as to say like oh because it's a shortcut, therefore it's not a good thing.
140
A good analogy would be like, okay, you got to go from New York to LA.
141
Do you take the direct flight or do you drive?
142
Do you take a train?
143
Do you walk?
144
Do you hitchhike?
145
Do you bike there?
146
We have newer technology.
147
As long as it's safe and not harming people, why not utilize good new technology for the better?
148
That's the way I would say it.
149
Now, before we move on to the next category of peptides, should you take a GLP -1?
150
Well, I think if you're already at a healthy body fat percentage, you feel good, and you're performing well, no. I do think diet and exercise should be your first go -to,
151
but if you've been struggling to lose weight and you've talked to your doctor about this medication, I think that's a decision that you and your doctor can come to.
152
We can debate whether the good outweighs the bad societally, but what isn't up for debate is that these peptides that we've covered so far clearly do a lot for fat loss.
153
So then, what in the world do the other peptides do?
154
Injuries suck, and they happen to every serious lifter at some point.
155
And until recently, your main options for treating an injury were basically physiotherapy and maybe surgery if it was serious enough.
156
But now, there's a peptide for that.
157
It's called BPC -157, and it has absolutely raving reviews.
158
You need to know about the BPC -157.
159
BPC -157 is a miracle compound.
160
It has anti -inflammatory properties, also blood -driving properties.
161
It tells damaged tissues how to heal.
162
BPC stands for Body Protection Compound.
163
And it's surprisingly simple.
164
Just 15 amino acids taken from a larger protective protein and human gastric juice.
165
It was developed by Croatian researchers in the early 90s while studying potential healing effects it had in the stomach.
166
To test those healing effects elsewhere, scientists gave BPC -157 to rats with an injured leg and discovered that,
167
yeah, 50 % more blood vessels formed in the injured leg.
168
More blood vessels should mean more blood flow and more nutrients going to the damaged tissue, which led later scientists to test BPC -157 in a variety of different tissues,
169
including muscles, tendons, and ligaments.
170
Once again, it accelerated healing everywhere it went.
171
But there's a catch, and it's a big one.
172
All those studies were done on rats, rabbits, and dogs, not humans.
173
BPC -157, the wolverine peptide all over the internet, has only ever been formally studied in 30 people.
174
That's it.
175
Compared with semaglutide or terzepatide, which have been tested on tens of thousands of people across multi -year, phase 3, placebo -controlled clinical trials,
176
BPC -157 has just three pilot studies with barely a small handful of subjects in each.
177
To be fair, those pilot studies did show some promise for knee pain, bladder pain, and safety, but they're still plagued by really small sample sizes and no placebo or control group.
178
There's no high -quality, well -controlled science.
179
There are plenty of anecdotes, though, and I think they're worth something.
180
I know people who've had an injury that's been nagging them for years suddenly heal up after taking BPC.
181
The internet is full of similar stories.
182
I was in a really bad car accident.
183
I immediately started taking BPC that day.
184
I was back at work in like two or three days.
185
I've been running the BPC because I have some pretty bad elbow inflammation.
186
But then a few days of being back on that, I have no issues, no inflammation, no pain.
187
I healed a little knee injury.
188
I healed some nerve damage.
189
I've healed my gut.
190
I've healed my shoulder.
191
I know that it works, and I know that it works super fast.
192
Eh, we need to be careful with these, though, because most injuries heal with time anyway.
193
If you started taking BPC and your shoulder finally started feeling better after six weeks, it's tempting to credit the peptide, and maybe it was the peptide,
194
or maybe your shoulder just started healing naturally on its own.
195
Without a placebo -controlled trial, it's hard to know.
196
In my opinion, the mechanism does make sense.
197
The animal data is intriguing, and I hope more high -quality human research happens.
198
But as of now, it's still not FDA -approved, it's banned by WADA, and sourcing it can be sketchy.
199
So as frustrating as injuries are, I'd stick to the boring stuff for now.
200
Manage your training loads, try to find pain -free variations, and gradually build yourself back up over time.
201
If your injury isn't getting better, have it looked at by a qualified physical therapist.
202
So before we cover the last peptide category, should you take BPC -157?
203
I think, no. I just don't think that the human evidence is there.
204
Sourcing can be sketchy, and even though the mechanism does make sense, I'd stick to the verified, safe, boring stuff for now.
205
but injuries aren't what most people are truly worried about anyway it goes deeper than
206
that but a lot of people are really worried about is aging getting older and looking older
207
the most ambitious peptide
208
that we've covered to date is this tiny little four amino acid peptide called epitalon
209
because unlike the glp1 peptides that promise weight loss
210
or the injury peptides that promise healing epitalon is aiming at something much bigger
211
aging itself epitalon works by targeting the most fundamental structure in
212
your entire body your dna every muscle tendon organ blood cell
213
that you've ever had has come from instructions encoded in your dna
214
and to keep those instructions protected your dna is packaged up
215
into chromosomes with these little caps on the end called telomeres as we get older those telomeres get shorter
216
and shorter and that may be one of the key reasons why we age in the first place
217
And it's why so much anti -aging research is focused on telomeres.
218
So this is where the peptide epitalon comes in.
219
It activates an enzyme called telomerase, which helps rebuild those protective telomeres as they shorten over time.
220
Sounds promising on paper, but does epitalon actually increase lifespan in the real world?
221
Well, actually, yes.
222
Yes, it does.
223
At least it does in flies, mice, and rats.
224
Unfortunately, when it comes to increasing our human lifespans, the only studies that we have is this 2003 study from Russia, and this 2006 study from the same Russian research group,
225
and neither study was independently replicated outside of Russia.
226
There's little doubt that telomeric shortening is involved in the aging process, but over -activating telomerase may be involved in cancer development, so it is a delicate balance.
227
And when it comes to epitalon, and frankly the rest of these peptides, the human evidence on anti -aging specifically just really isn't there at all that's kind of okay though
228
because humans are already uniquely well adapted for longevity
229
when you compare humans to other mammals of a similar size you consistently see
230
that humans live much longer and virtually all the compounds out there
231
that are being marketed as anti -aging solutions follow a similar
232
pattern they probably work in rats they might work in pigs sometimes they'll work in other primates
233
and then they do basically nothing when it comes to humans
234
but we don't really need to look for a peptide to help us live longer anyway
235
because the science is already quite clear on what helps slow aging down in humans.
236
It's relationships, friends, family, and community.
237
That's the big one.
238
And the rest is the same boring stuff you've heard about before.
239
Exercise, sleep well, don't smoke, don't drink too much, and try to maintain a healthy body weight.
240
Not as sexy as a new anti -aging peptide, but those truly are the things that move the needle the most.
241
So should you take an anti -aging peptide i think no the human evidence is just really really scant
242
and like i said we already know what helps with aging
243
the most it's the boring stuff my key message with this video is
244
that just because there are certain peptides
245
that do work for weight loss doesn't mean that everything
246
that falls under the category peptides will work for everything it's
247
ultimately your daily habits that'll determine how well you follow through on your health and fitness goals
248
one habit
249
that i follow through on pretty much every day is tracking
250
my nutrition with macro factor i'm a part owner of the app
251
and we've done everything possible to make it the easiest simplest
252
and most intuitive nutrition app on the market it isn't just
253
a tracker though it uses science -based algorithms to learn your specific metabolism
254
and then updates your calories and macros over time to mathematically guarantee
255
that you get to your goal as long as you stick
256
to the plan we have a really amazing community with over 500 000 users
257
and i think the app's reviews and testimonials speak for themselves
258
if you'd like to try it out just use code jeff
259
when you download on the app store or google play
260
and that'll get you two weeks for free there are zero ads on the app

262
if you ever run into anything that you're not sure about
263
so click the first link in the description box below
264
or scan this qr code on screen if you've never tracked your nutrition before
265
or you just haven't been consistent with it i really think
266
macro factor will help you get to where you want to be that's it for this one guys thank you

Контекст и фон разговора
Видео посвящено обсуждению пептидов — биологически активных соединений, которые становятся все более популярными в сфере здоровья и фитнеса. Спикер делится своими исследованиями, объясняя, как пептиды работают, их разновидности (для снижения веса, восстановления после травм и противостарения) и разницу с другими веществами. Диалог отличается научным тоном, но остается доступным, что делает его отличным материалом для практики аудирования и повторения.
5 ключевых фраз для повседневной коммуникации
- "Peptides are kind of insane" — "Пептиды действительно безумны" (выражение удивления или восторга).
- "it's wild" — "Это безумие" (отражение неожиданности).
- "I went down the rabbit hole" — "Я погрузился в это темное дело" (выражение глубокого исследования).
- "cut them down into shorter chains" — "разрезать их на более короткие цепочки" (простое объяснение химического процесса).
- "worth the hype" — "стоит такого хайпа" (оценка реальной ценности).
Пошаговое руководство по shadow speech для этого видео
Чтобы эффективно практиковать shadowing на этом материале, следуйте этим шагам. Сначала прослушайте фрагмент длиной 5–10 секунд и обратите внимание на интонацию (спикер часто подчеркивает важные моменты повышением тона). Затем повторите его сразу же, стараясь скопировать ритм и ударения — это поможет улучшить речевую плавность. Используйте shadowing site для записи своего повторения и сравните с оригиналом: обратите внимание на слова, которые вы пропустили или произнесли с ошибкой (например, "peptides" или "semaglutide"). Повторяйте каждый фрагмент 3–5 раз, пока не почувствуете, что ваше произношение близко к оригиналу. Этот подход работает, потому что shadowspeak тренирует мозг быстро анализировать и воспроизводить речь, что важно для повседневной коммуникации. Не забывайте: цель не в точном копировании, а в развитии способности понимать и говорить на английском естественно.
Грамматика в этом видео
Конструкции, которые говорящий использует чаще всего, с точными словами из видео:
| Конструкция | В видео |
|---|---|
| Present Perfect Continuous have/has been + -ing — действие началось раньше и продолжается | have been struggling · you've been struggling · I've been running |
| Present Perfect have/has + причастие прошедшего времени — прошлое действие, важное сейчас | you've probably heard · has become · I've published |
| Пассивный залог be + причастие прошедшего времени — важно, что происходит, а не кто это делает | can be linked · were told · be expected |
| Придаточные определительные who / which + предложение — уточнение о человеке или предмете | business, which is · people who set · people who are |
Что такое техника Shadowing?
Shadowing — это научно обоснованная техника изучения языка, изначально разработанная для подготовки профессиональных переводчиков и популяризированная полиглотом доктором Александром Аргуэльесом. Метод прост, но эффективен: вы слушаете аудио на английском от носителей языка и немедленно повторяете вслух — как тень, следующая за говорящим с задержкой в 1–2 секунды. В отличие от пассивного прослушивания или грамматических упражнений, Shadowing заставляет мозг и мышцы рта одновременно обрабатывать и воспроизводить реальные речевые паттерны. Исследования показывают, что это значительно улучшает точность произношения, интонацию, ритм, связную речь, понимание на слух и беглость речи — что делает его одним из самых эффективных методов для подготовки к IELTS Speaking и реального общения на английском.
