1
To be obese means to have too much fat on the body.
2
Obese people are not just overweight.
3
Such people are likely to suffer health problems because of their weight.
4
The precise cause of obesity is not clear.
5
However, it is clear that obesity is a problem in most countries.
6
One study estimated that about 55% of people in the United States are obese.
7
People need to understand what obesity is and how to tell
8
if they themselves are obese so that they can change their condition.
9
An obese person does not have to look extremely fat.
10
Even people who seem only slightly overweight can actually be considered obese.
11
If a person has a certain amount of fat on their body,
12
then their health might be in danger.
13
This amount of fat is usually thought to be 40% of the body's total composition.
14
Finding a person's exact fat percentage is troublesome.
15
Most people still rely on their weight measurement to tell them if they are overweight or obese.
16
There are problems with this method, however.
17
There are recommended weights for different ages.
18
In addition, weight alone says nothing about a person's percentage of body fat,
19
which is most important.
20
People have different body types,
21
which can make weight measurements unreliable.
22
For instance, athletes usually have more muscle mass than other people.
23
Muscle weighs more than fat.
24
Therefore, an athlete may weigh more than their recommended weight.
25
But this does not mean they are not healthy.
26
A more accurate measurement of body fat is needed.
27
Probably the most popular method of determining body fat today is the Body Mass Index, BMI.
28
BMI is a person's weight in kilograms divided by the square of his or her height in meters.
29
For men, a BMI is a person's weight,
30
in kilograms, divided by the square of his or her height, in meters.
31
For men, a BMI of 24 to 27 is normal.
32
For women, it is 23 to 26.
33
A BMI of 30 or more means a person is obese.
34
Many experts feel that BMI is a reliable way to determine if a person's weight is unhealthy.
35
However, others feel that BMI is too general to be really useful.
36
The numbers come from comparisons of large groups of people.
37
It is not related to an individual's body composition.
38
BMI says nothing about a person's actual percentage of body fat.
39
There are many different ways that BMI can be affected by body shape and size.
40
Muscular people may show a high BMI,
41
even though they are perfectly healthy.
42
Some people have higher bone density than others, which increases their weight.
43
In some cases, those who have very low body fat
44
and are also not muscular can have a BMI that is too high.
45
BMI is also unreliable for children and the elderly.
46
Even supporters of BMI think that it should not be used for people under 18 or over 70 years old.
47
Despite these criticisms, there are strong positive aspects of BMI.
48
The main one is that it is very simple.
49
The measurement can be performed easily.
50
It does not take special knowledge or equipment.
51
Though BMI is a general measurement,
52
it still gives useful information.
53
At least, it can suggest that there might be a problem.
54
Furthermore, some studies have shown that people with higher BMI numbers have a higher risk of health problems.
55
It takes only a minute to get a BMI number,
56
but the results can be very important to a person's life.

Why practice speaking with this video?

Engaging with a podcast like "Obesity" not only expands your knowledge on a pressing global issue but also enhances your speaking abilities in English. Listening to native pronunciation while discussing familiar topics, such as health and wellness, helps in shadow speech practice. This method allows you to mimic the speaker's intonation and rhythm, significantly improving your English pronunciation. By actively practicing with this video, you can develop not just vocabulary, but also the fluency and confidence needed for the IELTS speaking practice. Incorporating effective speaking techniques, especially through methods like the shadowing app, can greatly advance your English proficiency.

Grammar & Expressions in Context

  • Active Voice Usage: The speaker often uses active voice, such as "obese people suffer health problems," which directly connects the subject to the action. This structure is essential for expressing clear ideas in speech.
  • Comparative Structures: Phrases like "more reliable" and “less clear” demonstrate how to compare different aspects, a skill vital in academic and speaking contexts, especially for IELTS speaking practice.
  • Conditional Sentences: The use of conditions, such as "If a person has a certain amount of fat," enables nuanced discussion. Practicing conditional structures will help you articulate causes and effects in your speaking.
  • Quantifying Expressions: The speaker mentions statistics like "about 55% of people in the United States are obese." Learning how to use percentages and statistics can enhance the credibility of your arguments in discussions.
  • Descriptive Language: Terms such as "extremely fat" and "certain amount of fat" illustrate how descriptive adjectives can add precision to your speech, making your arguments stronger.

Common Pronunciation Traps

While practicing with this podcast, pay attention to some common pronunciation traps. Words like obese and statistics may pose challenges due to their uncommon stress patterns. Additionally, the phrase "Body Mass Index" can be tricky due to the rapid linking of consonants between words, which may make it hard to pronounce clearly. Incorporating a shadowing app can help you master these nuances, allowing you to hear how sounds blend together in natural conversation. Consistent practice will assist in avoiding common pitfalls and can remarkably enhance your overall English pronunciation.

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.
