1
Insulin resistance describes an abnormal process in the body that goes along with lots of medical conditions that are very common,
2
like type 2 diabetes, obesity, and atherosclerotic cardiovascular disease.
3
Insulin is a hormone produced by the pancreas
4
that helps your body break down the energy we eat and nutrients into substances it can use, like glucose, which is the medical word for sugar, and fats.
5
In states of insulin resistance, the body is not responding normally to levels of insulin that are being produced.
6
And as a result, we see lots of abnormalities.
7
The most common one we see is slightly elevated glucose.
8
Glucose won't always be elevated, but if the body isn't making enough insulin to keep up with insulin resistance,
9
then it certainly can be very elevated and lead to type 2 diabetes.
10
Lots and lots of different things can cause insulin resistance.
11
But when we commonly talk about insulin resistance occurring, it's usually because people are carrying extra weight, and that extra weight ends up getting stored in places it shouldn't be,
12
like liver and other tissues.
13
And that extra fat sitting in the liver then interferes with the body's ability to respond appropriately to insulin.
14
So there are lots of common conditions that go along with insulin resistance.
15
One of the most common is fatty liver, but there are other conditions such as polycystic ovarian syndrome, type 2 diabetes.
16
Fatty liver is a very common condition that you could be diagnosed with by a doctor, and that is described when people are really carrying extra fat in the liver.
17
When you take a big step back, the liver is really the factory that processes our energy.
18
And carrying extra fat in the liver interferes with a lot of a body's normal ability to function.
19
The good news is that when we overeat, the fat goes straight to the liver, but also when When we diet, the first place we lose weight is from the liver.
20
A common syndrome accompanied by insulin resistance without high blood sugars or diabetes is polycystic ovarian syndrome.
21
Polycystic ovarian syndrome is a syndrome characterized by irregular menstrual cycles.
22
People with PCOS often have very high insulin levels.
23
That said, the high insulin levels in PCOS probably to some degree drive the irregular menstrual cycles
24
and even to some degree drive the excess androgen or male hormone levels.
25
People often say insulin resistance causes type 2 diabetes.
26
And I want to point out
27
that that's not true unless the pancreas is not making enough insulin to keep up with the body's demand.
28
So there are many, many people who have insulin resistance, who are overweight with fatty liver, who don't have type 2 diabetes because their pancreas just produces more
29
and more and more insulin and keeps up to a large degree with the body's demand.
30
That's not a good situation because those high levels of insulin probably drive other abnormal body processes.
31
So even those people would benefit from weight loss.
32
But you really need insulin deficiency in combination with insulin resistance to lead to type 2 diabetes.
33
A lot of what determines insulin resistance is where excess weight is stored.
34
Some people tend to gain weight in their upper body and be sort of more apple-shaped.
35
Other people tend to store their excess weight in their hips or in their lower body and tend to be more pear-shaped.
36
It's actually the people who tend to store weight in what we call the apple distribution, the central weight, who tend to have much more problems with insulin resistance
37
because the excess weight is being stored in the liver and other abdominal organs, interfering with normal metabolic function.
38
So the best treatments for insulin resistance are also the best treatments for being overweight
39
or having obesity and also the best ways to just stay healthy overall.
40
Losing a modest amount of weight actually is very beneficial for insulin resistance
41
and the best way to achieve weight loss is through diet and exercise.
42
While many people give up on diet and exercise, in fact, relatively simple steps like eliminating sugary beverages,
43
including juices, having portion controlled meals that are balanced with a mixture of carbohydrates, protein, and fruits and vegetables,
44
particularly the healthy carbohydrates are very beneficial for insulin resistance.
45
And actually just exercising reduces insulin resistance, even in the absence of weight loss.
46
A lot of people feel it's very overwhelming to start an exercise program, but actually simple steps like walking 30 minutes over the course of the day,
47
even in three separate bouts of 10-minute exercise, things as simple as parking the car farther away, taking the stairs.
48
These things really make a difference over time and help reduce insulin resistance.
49
So people often wonder, should I take a medicine to treat insulin resistance?
50
Well, insulin resistance isn't really a disease in and of itself.
51
It's sort of the abnormal body process that goes along with many other conditions.
52
So if you have another condition that needs a medication, then by all means medications could be used to treat that condition.
53
The good news is that very simple steps, such as increasing exercise, healthier diet, and weight loss can dramatically improve insulin resistance
54
and reduce the risk of a lot of the health conditions that go along with it.
55
Thanks for joining me today.

このビデオで話す練習をする理由は？
「インスリン抵抗性」のテーマを扱ったこのビデオは、健康や体重管理に関する重要な情報を提供しています。英語を学ぶ際に、専門的な内容を聞き取り、表現することは非常に有益です。このようなテーマは、特にIELTS スピーキング対策においても役立ちます。具体的な医療用語や健康状態の説明を通じて、英語で話す自信を高めることができます。また、shadowspeakや英語シャドーイングのテクニックを用いることで、正確な発音や自然なリズムを身につける良い機会です。
文法と表現の文脈
このビデオでは、以下のような重要な文法構造や表現が用いられています。
- 「is described when」 - 状態や条件を説明する際によく使われる表現で、例えば「脂肪肝は人々が肝臓に余分な脂肪を持っているときに説明されます」。
- 「interferes with」 - 「妨げる」という意味を持つ動詞で、特定の現象が他のプロセスに影響を与えることを示します。
- 「it can certainly be very elevated」 - 現在形と副詞を使って、確実性を示す文の構造です。
- 「people often wonder」 - 一般的な疑問を述べる際に使用されるフレーズで、普遍的な考えや疑問を表すことができます。
これらのフレーズを練習することで、専門的なものであっても、自分の言葉で表現する力が鍛えられます。
一般的な発音の落とし穴
ビデオ内での発音には、特に注意が必要な言葉がいくつかあります。
- 「insulin」 - スラングに聞こえないように、母音の「i」を明確に発音することが大切です。
- 「resistance」 - 強調する音節があるため、リズムよく発音する練習をしましょう。
- 「polycystic ovarian syndrome」 - 長いフレーズであるため、分割して練習し、一つ一つの音を丁寧に発音することが推奨されます。
これらの言葉を練習する際は、YouTubeで英語学習のリソースを活用することで、視覚的に確認しながら練習できます。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
