When we exercise hard, we burn fat. But have you ever wondered where exactly the fat goes?

Some doctors think that fat is changed into heat and released in the air. Others think the body burns it. Some even joke that the fat fairy comes and takes it. That is why you always weigh less in the morning.

Now a new study from the University of New South Wales in Australia reveals the mystery. “the correct answer is that most of the mass is breathed out as carbon dioxide(二氧化碳). It goes into thin air,” says the study’s lead author, Ruben Meerman, to Science Daily. Scientists followed the atoms(原子) in 10 kilograms of fat as they are lost. They found that 8.4 of those kilograms are breathed out as carbon dioxide through the lungs. The rest of the weight —1.6 kilograms— becomes water that leaves the body in the form of fluids(液体) such as urine(尿), sweat, breath and tears. “None of this is obvious to people because we can’t see the carbon dioxide gas we breathe out,” said Meerman.

Does that mean you can lose more weight by breathing more? It is not as easy as you think. Breathing more than the body’s metabolic rate(新陈代谢) can make you uncomfortable. You may feel dizzy and become unconscious(无意识的), according the study. So how to lose weight healthily? The key is to eat less and move more. You many have heard this many times.

During a day, a 70kg person breathes out about 200g of carbon dioxide. So if the same person wants to lose weight, he or she can do some light exercise, for example, jogging. This can help lose 240g of carbon dioxide.

A.It is changed into heat and given off in the air. B.The body burns it.

C.The fat fairy comes and takes it. D.Most of it is breathed out as carbon dioxide.

2.What will happen to people if they breathe more than the body’s metabolic rate?

A.They will put on more weight. B.They will feel comfortable.

C.They may become unconscious. D.They may not lose weight at all.

3.Which of the following is a better way to lose weight?

A.Sitting still and breathing more. B.Sleeping a lot and breathing a lot.

C.Eating less and exercising more. D.Eating more and doing some light exercise.

4.Which is true according to the study from University of New South Wales?

B.Most of the kilograms of fat as they are lost are breathed out as carbon dioxide.

D.If we breathe more than the body’s metabolic rate, we will feel good.
