1 . Do you love holidays but hate the increase in weight that follows? You are not alone.
Holidays are happy days with pleasure and delicious foods.Many people，however，are worried about the weight that comes along with these delicious foods.
With proper planning，though，it is possible to control your weight.The idea is to enjoy the holidays but not to eat too much.You don’t have to turn away from the foods that you enjoy.The following suggestions may be of some help to you.
Don’t miss meals.Before you leave home for a feast (宴会)，have a small，lowfat snack.This may help to keep you from getting too excited before delicious foods.
Begin with clear soup and fruit or vegetables.
A large glass of water before you eat may help you feel full.
Use a small plate; a large plate will encourage you to have more than enough.
Better not have highfat foods.Dishes that look oily or creamy have much fat in them.
Choose lean meat.Fill your plate with salad and green vegetables.
If you have a sweet tooth，try mints(薄荷) and fruit.They don’t have fat content as cream and chocolate.
Don’t let exercise take a break during the holidays.A 20minute walk after a meal can help burn off excess calories(多余的热量).

Regular exercise can reduce a woman’s risk of cancer, but the benefits may slip away if she gets too little sleep, U.S. researchers said on Monday. The study involving 5,968 women in Maryland confirmed previous findings that people who do regular physical activity are less likely to develop cancer.
But when the researchers looked at the women ages 18 to 65 who were in the upper half in terms of the amount of physical exercise they got per week, they found that sleep appeared to play an important role in cancer risk.
Those who slept less than seven hours nightly had a 47 percent higher risk of cancer than those who got more sleep among the physically active women, the researchers reported at a meeting of the American Association for Cancer Research.
“We think it’s quite interesting and intriguing. It’s kind of a first look into this. It isn’t something that has been widely studied,” James McClain of the National Cancer Institute, part of the U.S. government’s National Institutes of Health, said in a telephone interview.
McClain, who led the study, said it is unclear exactly how getting too little sleep may make one more susceptible（易受感染的） to cancer. “Getting adequate sleep has been long associated with health,” McClain said.
The U.S. Centers for Disease Control and Prevention calls sleep loss an under-recognized public health problem, saying Americans are getting less and less slumber. The CDCP said the percentage of adults reporting sleeping six hours or less a night increased from 1985 to 2006. Sleep experts say chronic sleep loss is associated with obesity, diabetes, high blood pressure, stroke, cardiovascular disease, depression, cigarette smoking and excessive drinking.
In addition, research had shown that people who get regular exercise have a reduced risk of breast, colon and other types of cancer. Experts think the effects of exercise on the body’s hormone levels, immune function and body weight may play an important role.

3 . Should you work out in the gym in the morning instead of in the evening? It all depends. Of course, there are advantages of working out(运动) in the morning.
You will increase your energy for the rest of the day. “Morning workouts result in better energy levels throughout the day and give you more mental sharpness,” says Dr. Cedrie Byrant, Chief Science Officer of the American Council on Exercise.
Here is another advantage. In 2017, health researchers found that exercising in the morning helps you sleep better at night. According to the study, in all cases, those who exercised at 7:00am experienced about a 10 percent drop in blood pressure that carried through the rest of the day. They also had about a 25 percent drop in blood pressure at night, slept longer and had more beneficial sleep cycles than when they exercised at other times of the day.
However, there are disadvantages, too.
If you are not an early riser, getting out of the bed in the morning can be very difficult. Byran says that if you’re not used to exercising in the morning and force yourself to get up, you may not put as much effort into the exercise as you would later in the day. Also, if you aren’t careful, you can damage your sleep schedule, which can lead to insufficient sleep.
Besides, hitting the gym before work can cause a challenge in terms of scheduling. If you work a 9-to-5 job, getting ready for work and going to work can cut your morning workout short, Byrant notes.
To sum up, it has both advantages and disadvantages. If it suits you better to work out in the morning, you can do so.
