New Diet Trend in America: Intermittent Fasting
The latest diet trend in America is also an ancient human activity. The activity is fasting, or not eating food for a set amount of time.
Social media apps and Facebook groups are appearing for people who do "intermittent fasting," or fasting on a part-time basis.
Different approaches
Like other diets, intermittent fasting helps you lose weight by setting limits on eating. But instead of limiting what you eat, it limits when you eat.
One of the more popular approaches to intermittent fasting is called "time-restricted feeding." It is not as difficult as some of the other approaches, since the fasting period can include the time you are sleeping.
The basic idea of time-restricted feeding is to limit eating to an eight-hour period. You then fast during the day's other 16 hours.
Many people make the eating period shorter or longer. Some eat just one meal a day.
In other approaches, people fast several days during a week. On fasting days, some people may permit themselves around 600 calories.
Whatever the approach, people are not supposed to overeat when they stop fasting.
Supporters and critics
Melissa Breaux Bankston is a Crossfit instructor in New Orleans, Louisiana. She tried intermittent fasting as a way to reduce her snacking. "I wanted to limit the amount of time that I was eating," she said.
Studies on the potential health benefits of intermittent fasting are still limited, including for its effectiveness with weight loss.
For now, limited research suggests it may not be any better for weight loss than reducing calorie intake over the long term.
"It's really another way of fooling your body into eating less calories," said Krista Varady, who studies intermittent fasting at the University of Illinois at Chicago.
Courtney Peterson, of the University of Alabama at Birmingham, also studies intermittent fasting. She suggested the benefits of intermittent fasting are not as great as some might suggest. "Unfortunately, intermittent fasting gets a little hyped," she said.
Is intermittent fasting right for you?
Some health experts say intermittent fasting might be too difficult for many people. They point to a study of 100 people where those placed in a fasting group lost about the same amount of weight as those on diets that restricted calories. The fasting group had a dropout rate of 38 percent, compared with 29 percent for the caloric-restriction diet group.
But intermittent fasting may be easier for people who already skip meals when they are too busy, said Varady.
People interested in intermittent fasting should talk to their doctor before trying it. Health experts do not recommend intermittent fasting for children, people on some medications and people with a history of eating disorders.

美国的新饮食趋势——间歇性禁食
美国最新的饮食趋势也是一种古老的人类活动。这种活动就是间歇性禁食，或在一定时间内不进食。
供“间歇性禁食”或部分时间禁食人群使用的社交媒体应用程序和脸谱网群组正在涌现。
不同方法
与其他节食方法一样，间歇性禁食通过限制饮食来帮助你减重。但其限制地不是你的饮食，而是你的饮食时间。
一种比较流行的间歇性禁食方法名为“限时进食”。这种方法不像其他方法那样难，因为禁食期可以包括你的睡眠时间。
“限时进食”的基本概念是将进食限制在八个小时内。之后，当天剩余16个小时要禁食。
许多人会缩短或延长进食时间。有些人一天只吃一顿饭。
其他方法要求人们一周要禁食数天。在禁食日，有些人可能会允许自已摄入约600卡路里的热量。
无论采用哪种方法，人们都不应在停止禁食后暴食。
支持者和批评者
梅丽莎·布瑞鲁克斯·班克斯顿是路易斯安那州新奥尔良市的混合健身运动教练。她曾尝试用间歇性禁食来减少零食的摄入。她说：“我想限制自已吃东西的时间。”
有关间歇性禁食的潜在健康益处的研究仍存在局限性，包括这种方法对减肥的效力。
目前，有限的研究表明，间歇性禁食的减肥效果可能并不比长期减少卡路里摄入量更好。
在伊利诺伊大学芝加哥分校研究间歇性禁食的克莉丝塔·瓦拉迪说：“这其实就是哄骗你的身体减少卡路里摄入量的另一种方法”。
阿拉巴马大学伯明翰分校的考特尼·彼得森也在研究间歇性禁食。她认为，间歇性禁食的益处并不像某些人所说的那样大。她说：“不幸的是，间歇性禁食有些被夸大了。”
间歇性禁食适合你吗？
一些健康专家表示，间歇性禁食对大多数人来说可能太难了。他们指出，一项对100人进行的研究表明，禁食组与饮食限制热量组减掉的体重大体相同。禁食组的退出率为38%，而饮食限制热量组的退出率为29%。
瓦拉迪说，但对于忙碌起来就不吃饭的人来说，间歇性禁食可能比较容易。
对间歇性禁食感兴趣的人在尝试禁食前应该先咨询医生。健康专家不建议儿童、服用药物者以及有饮食失调史的人尝试间歇性禁食。
