If you really want to see that number on weight loss, what you put in your mouth matters most. People who simply cut calories to lose weight lose about 2 pounds a week, says a study in the International Journal of Obesity and Related Metabolic Disorders. At the same time, people who exercise but don't cut calories drop less than half a pound each week.
Why doesn't the physical activity produce the same pound-dropping results as calories cut? One thought is that though exercise burns calories, it doesn't increase your metabolism (新陈代谢), says a study in Obesity Reviews. It doesn't prevent your metabolism from slowing as you lose pounds. As you slim down - through any method - your metabolism slows with your weight loss and exercising doesn't keep that from happening. As you lose weight, you burn fewer calories through exercise. For example, a 150-pound person who exercises for 30 minutes burns about 306 calories. After losing 10 pounds, that person will burn about 286 calories doing the same exercise. So to burn 306 calories, you need to extend (扩大) your exercise.
A research shows people who diet and exercise for weight loss drop the same amount of weight as people who have a balanced diet. They are, however, more successful keeping the weight off than their counterparts (相当的人) who simply eat less.
| A．If you want to put on weight, you should eat more. |
| B．If you want to lose weight, you should eat more. |
| C．If you want to lose weight, you should have a balance diet. |
| D．If you want to lose weight, you should exercise more. |
| A．Because it doesn't increase metabolism. |
| B．Because it doesn't burn calories. |
| C．Because it bums less calories than calories cut. |
| D．Because calories cut slows metabolism. |

Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts，but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of colours is protecting themselves. bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
