So what we're going to talk about today is really why?

治療性斷食以解決兩倉儲問題 【酮好字幕組】(翻譯：曾建璋)

intermittent fasting and low carbohydrate diets work Whereas the Calorie counters

It just doesn't seem to work right and the problem with the calorie

為什麼間歇性斷食法和低醣飲食是有效的

但計算卡路里的飲食法  卻似乎不太有效

Because we don't really understand obesity

That's why we can't cure it right, so I'm sure many of you have seen this show. It's called the biggest loser and it's on

It's everywhere right and what people do is [they're] contestants that compete to lose weight, and they get put on a diet

It's a calorie reduce diet and they do a lot of exercise, and you've seen Jillian Michaels screaming at everybody, right?

那就是為什麼  我們無法治癒肥胖

So it's a lot of exercise, and they don't show it on the show, but there's actually a fairly severe caloric restriction as well

我相信各位都看過有個節目叫「減肥達人」 (譯註：「減肥達人」是一檔美國真人實境秀節目)

It's more of a kind of everything in moderation

在北美、澳洲、世界各處都在播

sort of an approach, so the problem of course is that this show has been running for a long time and

Certain of the Contestants have come out and said well

[you] know this really doesn't work now the reason more haven't come out is because they're essentially under a legal gag order, right?

they're actually not allowed to say any of this stuff, but certain contestants have actually come out and

So this contestant Suzanne said well they never do a reunion show why they've all gain that weight again

你也看過 Jillian Michaels 對每個人大吼

Unique to the biggest loser [a] lot of diets and we've all done these Calorie reduce diets

it does the same for everything it does fine for about six months, but then after that it just

但他們相當嚴格地  限制飲食的卡路里

Keeps coming back your weight plateaus then it starts to come back and everybody knows this right because everybody's done this diet

比較像是  各種食物都適量的方式

Right and that's what we really have to understand and that's what I mean by we have to solve the two compartment problem

And I'll explain that in a second so the biggest loser diet despite the fact that we all know it doesn't work is

actually ranked very highly so Usa news for example just this past year put the biggest loser diet at

Number three for weight loss and number 11 overall so really a very good diet and why not it's a eat less move more

Sort of approach, right cut your calories in increase your calories out and hey presto. You're going to lose weight

So that's why it does so well because all the doctors recommended and so on

是因為他們都簽了類似保密協定的文件

The thing is that there have been some studies that have been done [on] these contestants, and it's very interesting to [look]

Scientifically at what actually happens to these people as they do this sort of eat

Less news more approach now the biggest loser of course is that approach on

Steroids [rates] or eating a lot less, and you're moving a lot more, and that's why you get these dramatic weight losses

「他們從來不辦同學會特別節目」

So one season they actually took these contestants made them signed consents

「為什麼呢？因為大家全都胖回去了！」

And then actually did metabolic studies on them and what's interesting is that at first it looks amazing, [right]?

[and] [we've] all seen [that] show right the before on the after it looks amazing and

the studies really bear that out, so if you look at the before [and] after if you look at the

我們都親身經歷這種  限制卡路里飲食

composition of weight loss so at week [six] and week 30 at the end of the

Show is week 30 you can see that. They've lost a lot of weight right. This is 60 kilograms right and this is

Fat mass so most of it is fat right everybody says [aw], you're going to lose muscle. You lose muscle another losing mostly fat

There's a little bit of muscle loss, but it's mostly fat

and this is their body fat percentage you can see it's follows a pretty steady trend downwards and

329 pounds to 202 pounds so an amazing result right body fat [went] from 49% to

28% so at the end of the show you get these great results

You have the end of the show everybody wins and they pretend like everything's fine, but we know that it isn't

And why not? What's the problem? It sounds like it should work, right?

這就是我們必須深入了解的部份

You keep doing what you're doing, and you'll keep losing weight

But you don't and the reason and we've known this for [at] least a hundred years is

我們需要解決兩個倉儲所造成的問題

that your metabolism starts to slow down, and this is what happened to the metabolism of all these contestants, and you can see in the

Solid bar that's their baseline rate of metabolism

Before they start at this and the open circles is that afterwards you can see that in virtually every case

雖然事實上  我們都知道那是行不通的

These people are cutting the amount of calories they expend by a lot

okay, so you can look at some of these dramatic examples, so this fellow for example [list] starts out by

Earning Thirty five hundred calories a day and he's dropped all the way to about seventeen hundred [calories] a day, right

在減重飲食項目「減肥達人飲食」名列第三

在所有飲食中也排名到第11名 (譯註：其他的飲食包括降血壓、改善老年痴呆症等…)

Decrease in metabolism is over seven hundred calories a day

right, so [if] you start by burning Thirty five hundred

Which is a lot, so you start at two thousand you're going to drop down to like

Twelve Thirteen hundred by the end of the show so you wonder why you're not losing weight?

It's because your metabolism has slowed down so much that if you're burning thirteen hundred and you are eating

[1,500] remember that's still a lot less than you used to eat

有些針對「減肥達人」參賽者的研究

從科學的角度來看是很有意思的

you feel cold [you] feel tired if you're hungry, [you] feel like shit and

他們在配合「少吃多動」的方法時

Right and that's the problem right we all know that's the problem. It's the decrease in metabolism

「減肥達人」的方法就是「少吃多動」的極致

So you can try to make up for it with more exercise, right?

And that's what they pretend that you can do so you can see that baseline. There's a certain amount

那就是為何能得到如此有效的減重成果

Which is resting metabolic rate certain amount of exercise?

During the show they burn a hell of a lot of calories as exercise you see that the gram tops your total energy expenditure

Is better but when you stop exercising for like you know five hours a day?

Then your exercise goes down, but look at what's happened to your basal metabolism

This is your resting metabolic rate. It's already gone down by week six okay, so don't kid yourself

But by week [thirty], it's gone down even or and that's the whole problem you get this

Metabolic Slowdown and because you're not burning as much energy. You don't have that you know liveliness

看體重減少的成份  (譯註：左圖)

In this graph you can see this is the biggest loser contestants, and you see that the basal metabolic rate just keeps on going down

Extreme measure that doesn't seem to have this problem and the question is why?

你可以看出他們減了相當多的體重

So you can look at bariatric surgery so bariatric surgery is stomach stapling surgery, right?

So you cut your stomach into the size of a walnut you

而這是減去的脂肪重量  (譯註：約50公斤)

Really just can't eat and you can't eat for months and months and months and guess what the weight goes down, right?

每個人都說「你會減掉肌肉、你會減掉肌肉」

the surprise is that it works to keep weight off in the long term yeah, there are a lot of problems with this okay, so

Let's be clear. I'm not recommending it for anybody, right?

but if you look at the resting metabolic rate

with a similarly sort of extreme measure it goes back up the

Study of the long-term effects of bariatrics and you can see that a baseline and a follow-up. This is several [years] [later]

The resting metabolic rate and the total energy expenditure how much energy you're burning has really not gone down

Right as opposed to the eat less move more where it keeps going down keeps going down until you fail, right?

That of course is the saddest part of all right the saddest part of the entire thing is that we know about this

所以當季結束  得到很好的結果

1915 so we've known about it for a hundred years
