Dieters' who eat meals high in protein might lose a bit more weight than those who get less protein and more carbohydrates (碳水化合物)一all other things being equal, a new analysis of past studies suggests. Researchers found that over an average of 12 weeks, people having a high一protein diet lost about 1.8 extra pounds, and more body fat, than those having a standard-protein diet.
Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”
1.According to Wycherley’s analysis, dieters should take in more ______.
A. fat B. carbohydrates C. protein D. calories
2.What can we learn from the studies?
A. It bums more calories to deal with carbohydrates.
B. Protein helps keep muscle mass which bums calories.
C. Vegetables contain more protein than animals.
D. No more calories are burned while the body is resting.
3.What is Levine’s attitude towards the conclusion of the studies?
A. Doubtful. B. Supportive. C. Curious. D. Agreeable.

Myth: Skipping meals helps you lose weight fast.
Truth: There’s no truth in this advice. Not only will you lose weight by starving yourself, but according to Carol Ann Rinzler, this may actually cause you to gain weight. Rinzler reasons that missing a meal causes your metabolism(新陈代谢) to slow down so that you burn food more slowly. This only makes you feel hungrier and by the time you finally do reach the table you will probably eat more food. Strange as it may seem, studies show that eating several small meals and snacks throughout the day is a more healthy way to lose pounds.
Myth: If you swallow (吞下) gum (口香糖)，it will stay inside your stomach for seven years.
Truth: Actually, it takes just a few days for gum to make its exit---not seven years, says Nei Izenberg, M. D., editor of Kids Health Organization. But because gum is made of the same thing as rubber, it cannot be fully digested (消化) in your stomach--- so if you gum up the works on a regular (经常的) basis, you might find yourself in a sticky situation.
Myth: The best way to stop a nosebleed is to lift your head back.
Truth: Now that’s bad advice. Bloody noses are caused by broken blood vessels (血管), so while lifting your head back might stop the fluid from rushing out of your nose, it won’t stop the bleeding; you’ll just end up swallowing lots of blood. Your best bet? “Rest quietly. Don’t poke or pick, and the blood will naturally clot (凝结) within a minute or two”. Suggests Dr. Izenberg.
Myth: Cutting your hair will make it grow long faster.
Truth: That’s not true. “Your hair isn’t like a lawn or a rosebush, where cutting can stimulate (刺激) fresh growth,” says Phillip Kingsley. The length of your hair is genetically ( 遗传地) determined. When it reaches a certain length, it stops growing. When you clear up the dead split ends, this make your hair look healthier, but not necessarilylonger.
1.According to Carol Ann Rinzler, skipping meals will __________.
A. help you lose weight fast
B. help you lose weight slowly
C. cause you to become fatter
D. make you burning food more quickly
2.Which of the following statements is NOT true according to the passage?
A. Gum cannot be fully digested in the stomach
B. Gum can leave your stomach after you swallow is a few days later
C. If you often swallow gum, you might find yourself in a sticky situation
D. Gum can stay inside your stomach for seven years if you swallow it
3.The length of your hair is determined by ________
A. clearing up the dead split ends
B. your gene
C. cutting it often
D. the food you eat
