Hello, everybody.
Welcome to Studio Classroom Worldwide.
Thanks for joining us.
My name is Steve.
Go to any bookstore's Health section, and you'll see a huge selection of books
about dieting.
One book might claim: Lose weight by eating three grapefruits a day.
Another might say: Eat whatever you want but not after six o'clock at night.
Now all this leads me to wonder: With so many different opinions about losing
weight, are any of them right?
Well, to help dispel some of the confusion surrounding dieting,
Studio Classroom is going to look at six diet myths and the truth behind them.
Let's look at some of these myths starting on page 48.

Diet Myths.
Get the facts, or your diet may fail!
Dieting is hard work, and there are plenty of "helpful" diet tricks that can
make weight loss even harder.
Here are six common myths about losing weight and the truth behind them.
1. Carbs are bad for you.
Carbohydrates are actually an important source of energy.
There are good carbs and bad carbs.
Refined and processed foods, like white bread or white rice, are examples of bad
carbs.
Good carbs include whole wheat bread and brown rice.
They're rich in fiber and really good for you!
2. Skipping meals helps you lose more weight.
On the contrary, studies show that people who eat breakfast tend to eat fewer
calories throughout the day.

Hello, friends.
Thank you for joining us.
My name is Ryan.
And my name is Kaylah.
And today we are talking about Diet Myths.
That's right.
Now this is our HEALTH article for the month.
And many of you would might... or might want to start a diet.
Friends, if you want to lose weight, then you can try taking a diet.
But oftentimes you hear a lot of advice of what you should do, but maybe it's
really just a myth.
That's right.
Now a myth is something that is not true.
Often a myth refers to something many people know.
So it's... mythology is those stories that are not true but we all understand
them.
Now a diet myth would be something that everyone thinks is true but actually is
not.
OK. Now Kaylah, this is our HEALTH article for the month.
And an important point that I think we should make is it's OK to lose weight but
only do it in order to stay healthy.
Don't just do it because people tell you to or just because you want to look
thinner.
That's right.
Now we're not telling you you need to diet or that you have to take time to do
that.
But if you want to be healthier and would like to try a diet, that's OK, but
make sure you get the facts first.
Or your diet may fail, and you can also end up not healthy.
So this is a HEALTH article, stay healthy.
Don't worry about being super skinny.
All right. So now let's get the facts.
We know dieting is hard work, and there are plenty of "helpful" diet tricks that
can actually make... weight lost even harder.
Well, we're going to get started with this.
But that first sentence is our Grammar on the Go.
So let's visit Liz and then we'll get started into our Diet Myths.
Hi, friends. I hope you're doing well today.
My name is Liz.
And it's time for Grammar on the Go.
So we're talking about dieting in today's HEALTH article.
And the writer says:
Dieting is hard work, and there are plenty "helpful" diet tricks that can make
weight loss even harder.
That's our Grammar Tip sentence.
Now if you have your magazine with you, you'll notice how the word "helpful" is
marked with quotation marks.
We normally use quotation marks for titles or to show what someone said.
But in the case of today's sentence, the quotation marks are there to show
sarcasm.
In other words, what is said and what is meant are opposite.
So what the writer is saying is there are thse diet tricks that claim to be
helpful.
But in reality, these diet tricks make weight loss even harder.
These diet tricks aren't helpful.
They are not helpful.
Let's have a look at some other examples of how we can use quotation marks for
sarcasm.
We know that most people don't enjoy going to the dentist.
And if you're one of those people, you can say:
I get "excited" whenever I have a dentist appointment.
Or: Finney hasn't done laundry for a very long time, but he'll try to find
something "clean" to wear for his job interview.
If you'd like to see some more example sentences, then check out the Grammar
section in today's article in your magazine.
That's all the time we have for today.
This is Liz with Grammar on the Go signing off.
Bye-bye.
All right, friends.
It's important to get your facts straight.
So first, let's show you what some of the common myths about dieting are.
That's right.
Here we're talking about six common myths about losing weight and the truth
behind them.
So we know that a myth is not true.
So we're going to look at what is true in each situation.
OK. Number 1, the first diet myth that we have is that carbs are bad for you.
"Carbs" are also known as carbohydrates.
That's right, Ryan.
And "carbohydrates" is our first vocabulary word to look at.
Now carbohydrate refers to a substance that supplies energy in the body.
And often we get these from bread, pastas, rice and potatoes.
So these are things in our bodies that we need to create energy.
But often our myth says that carbs are bad for you.
Yeah. Now carbohydrates are stored in your body usually as fat.
So then people think: Well, if they are kept as fat, then you should eat less,
and you will lose that fat.
But we find that carbohydrates are actually an important source of energy.
You need them.
That's right.
As I said, they give you energy.
You need them to have energy.
If you have no carbohydrates, your energy gets really weak.
So there are good carbs and there are bad carbs, so let's break those apart.
OK. Now refined and processed foods, like white bread or white rice, are
examples of bad carbs.
That's right.
That word "refined" means they are made a certain way or pure by removing other
substances from them by taking things out.
Now when you have white bread or white rice, they have been bleached,
and something has been brought out of it, usually the most nutritious part.
So these are bad carbs because they're giving you that fatty substance without
all the other vitamins and minerals you need.
Typically, foods are refined to make them taste better or look better.
And that can also be used with the word "process." That means something is
changed in the food.
But people usually don't make them healthier.
They usually take out whatever makes the food healthy.
Now good carbs include whole wheat bread as well as other things.
That's right. Whole wheat bread and brown rice are good examples.
They have that natural color.
They're rich in fiber and are really good for you.
So if you're going to eat rice, if you want to be healthy with your carbs, eat
brown rice instead of white rice.
And eat wheat bread or grain-based bread instead of just white bread, and you're
getting good carbs.
That's right.
You're also getting fiber.
These foods are rich in fiber, which means they have a lot of it, and that is
really good for you.
OK. Number 2 is skipping meals helps you lose weight.
Well, on the contrary, studies show that people who eat breakfast tend to eat
fewer calories throughout the day.
OK. Something that is "on the contrary" shows that it is the opposite of what
you might think.
That's right.
So people think: Oh, if I don't eat breakfast, I'll lose weight faster.
Don't skip a meal.
Eat all of your meals.
It will help you eat fewer calories.
All right.
We'll talk about calories and more after we visit the Chat Room.
Hey, Ken.
You're leaving pretty early today.
No. I'll be back.
I'm just going out to get some coffee.
Would like to join me?
I'd love to, Ken, but I'd better not.
If my supervisor catches me playing hooky, I'll be in big trouble.
Playing hooky? Hmm. I don't think I've ever played that game.
No, Ken.
"Playing hooky" is an expression used for people who skip school.
But you're not in school.
Well, it's commonly used to refer to people who skip school, but it can apply to
workers too.
Oh, I see.
And when you say skipping school, you're talking about playing hooky, right?
That's right. You got it.
So did you skip school very often when you were a kid?
No, not often.
I tried it once, got caught, and then got in so much trouble that I never tried
it again.
So what about you, Ken?
Nope, never skipped school.
And another thing I hardly ever skip is breakfast.
I'm with you there.
I never miss eating breakfast if I can help it.
Hey, I'm wondering other than skipping school and skipping meals, are there
other things people can skip?
There are. But they don't all use "skip" in the same way.
Skipping school or skipping a meal means to avoid those routine activities.
But skipping a question on a test would mean to leave it and move on to the next
item.
That's what one of my high school teachers always said.
When you don't know the answer to a specific question, just skip it and go on to
the next one.
That's pretty good advice.
Oh, by the way, do you mind bringing me back a coffee?
No problem. I wouldn't want you to skip your coffee break.
Thanks, Ken.
