This is 6 Minute English from bbclearningenglish.com.
2
Hello, I'm Rob.
3
And I'm Finn.
4
And this is 6 Minute English.
5
In today's programme, we're talking about slimming.
6
In other words, doing something to lose weight and get thinner.
7
Not a problem for you, Finn, eh?
8
Well, actually, Rob, I do have a small tyre of fat that's growing around my middle.
9
So, even I don't have a perfect body.
10
Well, it doesn't show and maybe you are what we call toffee, OK?
11
That's thin on the outside and fat on the inside.
12
Toffee, OK, right.
13
But for people who perceive or think they may be fat on the outside, there could be some good news.
14
Mm-hmm, and this is to do with research about the temperature of your house.
15
We'll explain more soon and we will look at some related vocabulary.
16
But first, Rob, have you got a question for me?
17
Of course I have, a big fat question for you.
18
Very good.
19
This is about calories.
20
These are the units that measure how much energy you get from food.
21
People who want to lose weight try to eat food with fewer calories in them.
22
But what is the recommended number of calories an average man needs each day to maintain a healthy weight?
23
Is it a 2,000 calories, b 2,500 calories, or c 3,000 calories?
24
Oh no, I should know this.
25
I think it's c 3,000 calories.
26
Wow.
27
Okay.
28
That sounds a lot, doesn't it?
29
It does.
30
We'll find out if you're right later on.
31
Thank you.
32
Let's talk more now about a possible new way to slim or lose weight.
33
New research has found that heating your house too much could make you fat.
34
Mmm, and turning the central heating down could make you lose the pounds.
35
This is the claim from Dr. Wouter van Markenlichtenbelt, who is a biologist at Maastricht University Medical Centre.
36
Yes, that's right.
37
He got some brave volunteers to spend six hours every day for ten days indoors,
38
in temperatures of just 15 to 16 degrees Celsius, whilst just wearing T-shirts and shorts.
39
Now, that's not something I would normally do.
40
But these guinea pigs, now that's a name for people who are used in experiments, became accustomed to, or used to, the cold.
41
And their metabolism worked faster.
42
Yes, metabolism is an important thing.
43
This is the chemical process in your body that causes you to burn food and turn it into energy.
44
So in this research, living in cooler conditions made people's bodies burn food faster.
45
Yes, so they burnt off the calories and that means they lost weight.
46
It sounds like a simple and easy diet, doesn't it, Rob?
47
I like the sound of this.
48
It doesn't really involve too much effort.
49
It doesn't mean, though, you can just be a couch potato.
50
You still need to do some exercise.
51
But living in a cooler temperature could help to some extent, and this is because of brown fat.
52
Mmm, brown fat, huh?
53
Now let's find out more about this from Dr. Wouter van Markenlichtenbelt,
54
who's been speaking to the BBC's Health Check programme.
55
What happens to brown fat when it is activated?
56
Brown fat cell is really not filled with fat but with other particles that can increase energy metabolism a lot.
57
So as brown fat gets activated, it produces heat, so it warms up the body.
58
Ah, so he says brown fat isn't actually fat.
59
It has particles that help to increase your metabolism.
60
When it's activated, or when it starts working, it makes heat and that warms up the body.
61
Yes, it's interesting stuff.
62
And brown fat actually increases after living in cold conditions.
63
It's particularly found in animals that hibernate, the ones that sleep during the winter.
64
A similar experiment took place in Japan, which led to people losing weight.
65
But I find if the temperature is colder, I want to eat more to warm up.
66
particularly unhealthy food, or what we call comfort food.
67
Oh yes, me too.
68
But the doctor says we mustn't, and he explains that losing weight this way also depends on other lifestyle factors,
69
so other ways we lead our life, such as exercise and what we eat.
70
But he does feel understanding environmental conditions – that's where we live and work – could be useful in the future.
71
He thinks a factor like temperature has been neglected, or not thought important.
72
And he believes it should be thought about when designing heating and cooling systems for homes and offices.
73
Now, what does this mean?
74
Does it mean I'm going to be shivering like that when I'm at work?
75
Well, it will mean you'll be producing extra brown fat instead of that other fat you've got.
76
Yes, only a little.
77
But seriously, the doctor is just talking about turning the temperature down a few degrees, not turning the room into a freezer.
78
It would certainly help reduce electricity and gas bills, wouldn't it?
79
Well, it's time now to reveal the answer to the question I set you earlier.
80
I asked you, what is the recommended number of calories an average man needs each day to maintain a healthy weight?
81
I said C, 3,000 calories.
82
That's a lot of calories.
83
The answer is actually 2,500 calories.
84
2,500 calories.
85
500 too many.
86
The recommended number of calories for an average woman is 2,000 calories per day.
87
OK.
88
Well, that brings us to the end of today's Six Minute English.
89
Please join us again soon.
90
Bye-bye.
91
Bye.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
