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.

2. Why can't the physical activity help people lose the same weight as calories cut?

There are some popular diets that will lead to successful weight loss if you follow them exactly as they are designed. That means you have to change your own eating habits to fit the diets' rules.
The__closer__the__food__is__to__its__natural__state,__the__better__it__is__for__us. Fresh fruits are good for our health. Vegetables have lots of vitamins and minerals. So you had better eat more vegetables. Cook them to keep the most value and be careful with sauces. They may be high in fats that aren't good for you.
Any pasta or baked food should be made from whole grains. Avoid sweet food as well. An apple is good for you, but an apple pie really isn't.
Shop for lean meat(瘦肉) and don't forget the fish. Lean meat may be healthier than higher fat beef. Serve seafood two or three times per week. Baked fish and chicken are healthier than the fried. And hot dogs, bacon and sausages have a lot of fat and nitrates(硝酸盐) that you don't want in your body.
Have more water, milk, fruit and vegetable juice as your main drinks and limit sweet soft drinks. If you get tired of plain water, you may add some lemon and so on. For kids, try some fruit juice without carbonated(含二氧化碳的) water.

If you want to see a thing well，touching can help you to “see” it better.
Your eyes can tell you that a glass ball is round. But by holding it in your hands，you can feel how smooth and cool the ball is. You can feel how heavy the glass ball is. When you learn all these about the ball，you really see it well.
With your skin，you can feel better. For example，your fingers can tell the difference between two different coins in your pocket. You can feel a little drop of water on the back of your hand，too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music. All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops，we touch things that we might buy. To see something well，we have to touch it. The bottoms of our feet can feel things，too. You know this when you walk on warm sand，cool grass or a hard floor. All feel different under your feet.
Most museums are just for looking. But today some museums have some things to touch. Their signs say，“ Do touch!” There you can feel everything on show.
There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet，the clothes on your body，the air on your skin.
