   When we exercise hard,we bum fat. But have you ever wondered where the fat 61. goes?

Some doctors think that fat is 62. into heat and released in the air. 63. think the body burns it.

Some even joke that the fat fairy comes and takes it. That's why you always weigh 64. 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. It goes into thin air," the 65. lead author,Ruben Meerman,said to Science Daily .

Scientists followed the atoms in 10 kilograms of fat as they were lost. They 66. that 8. 4 of those kilograms were breathed out as carbon dioxide through the lungs. The rest of the weight — 1. 6 kilograms — became water that left the body in the form of fluids such as urine (尿) ,sweat,67. 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 body9s metabolic rate (新陈代谢速度) can make you 68. . You may feel dizzy and become unconscious,according to the study.

   So how to lose weight 69. ? The key is to eat less and move more. You may have heard this many 70. .

During a day,a 70 kg person breathes out about 200 g 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 240 g of carbon dioxide.
