????33年前簡(jiǎn)?費(fèi)爾茨加入麥當(dāng)勞的時(shí)候還只是負(fù)責(zé)炸薯?xiàng)l，當(dāng)她快要55歲那年，她已成為這個(gè)快餐連鎖集團(tuán)的美國(guó)總裁。她說(shuō)，“有天醒來(lái)后我對(duì)自己說(shuō)，‘天啊！我怎么變得這么胖了？’”

????與她掌管的14,000家麥當(dāng)勞連鎖店的上百萬(wàn)顧客一樣，費(fèi)爾茨也是在不知不覺(jué)間長(zhǎng)胖的——“每次10磅：10磅，10磅，10磅，然后突然間，我看了看自己，不禁驚呼，天哪，我重了90磅。我怎么長(zhǎng)這么胖了？”

????誠(chéng)然，麥當(dāng)勞一直是評(píng)論家們公認(rèn)的美國(guó)肥胖問(wèn)題的罪魁禍?zhǔn)?，但是費(fèi)爾茨堅(jiān)持認(rèn)為她本人發(fā)福的根源不是食物，而是缺乏鍛煉?！拔也辉趺催\(yùn)動(dòng)，”她承認(rèn)，“整天除了上班，就是回家睡覺(jué)”。

????費(fèi)爾茨在財(cái)富（Fortune）最具影響力女性名單中位列第25名，并不怎么引人注目：她在印第安納州的小城鎮(zhèn)文森尼斯長(zhǎng)大，來(lái)自于一個(gè)有8個(gè)孩子的家庭，排行老七。小時(shí)候她一直很纖瘦，并夢(mèng)想著長(zhǎng)大了當(dāng)一名修女，后來(lái)又憧憬著當(dāng)一名律師。但她隨后結(jié)識(shí)了她丈夫，早早地結(jié)了婚，生了個(gè)女兒。23歲那年，在開(kāi)車去參加建筑公司秘書招聘面試的路上，她上麥當(dāng)勞喝了一杯可樂(lè)，碰巧看見(jiàn)了“招聘”的牌子。其實(shí)，那是費(fèi)爾茨第一次在麥當(dāng)勞用餐。由于囊中羞澀，她和曾是空軍的丈夫從未在餐館吃過(guò)飯。

????由于一時(shí)心血來(lái)潮，她接受了麥當(dāng)勞的工作，時(shí)薪2.65美元。上班第一天晚上回到家，她大哭一場(chǎng)——“糟透了”。后來(lái)公司把她從煎炸部調(diào)到了前臺(tái)做客服?！安灰?yàn)槟臣禄蚰硞€(gè)人而放棄，”她說(shuō)。由于在工作上恪盡職守，在領(lǐng)導(dǎo)風(fēng)格上平易近人，勵(lì)精圖治，她在公司一路平步青云。

????一直以來(lái)，由于在工作上太賣力，她很難抽出時(shí)間去大學(xué)深造或保養(yǎng)身體。直到有一天，在約見(jiàn)了一位營(yíng)養(yǎng)師之后，她才下決心向肥胖開(kāi)戰(zhàn)?！耙婚_(kāi)始，我主要是在健身房的跑步機(jī)上練習(xí)”，她說(shuō)，只要有走道的地方，就能健身，“我并沒(méi)有請(qǐng)教練。”

????她開(kāi)始加大飲水量，不喝汽水，即便是無(wú)糖汽水。費(fèi)爾茨每天仍然都在麥當(dāng)勞用餐，只是和過(guò)去相比，吃的種類不同，份量也更少。早餐是麥當(dāng)勞的燕麥粥或雞蛋麥?zhǔn)纤娠灮蛩退崮虄龈?。她在伊利諾伊州奧克布魯克辦公，辦公室附近有一家麥當(dāng)勞，這也是她午餐的地點(diǎn)，午餐菜譜通常是烤雞三明治或芝士堡，并搭配少量法式薯?xiàng)l和冰茶。

????晚餐不在麥當(dāng)勞吃——工作之余她也有自己的生活。通常，她會(huì)點(diǎn)通心粉，她常說(shuō)，“我是西紅柿干酪沙拉的粉絲。這是我一直以來(lái)最鐘愛(ài)的一道菜”

????健康飲食為費(fèi)爾茨帶來(lái)了健康，也造福了公司。全新的食品比如冰沙和燕麥粥幫助公司擴(kuò)大了客戶群，同時(shí)也帶來(lái)了更豐厚的利潤(rùn)，公司股價(jià)也在近期升至歷史新高。與此同時(shí)，麥當(dāng)勞上周宣布，旗下店面將為開(kāi)心樂(lè)園餐（Happy Meals）搭配水果或蔬菜，并減少薯?xiàng)l的分量，這意味著“公司為迎接重大轉(zhuǎn)變邁出了第一步”，費(fèi)爾茨說(shuō)。

????費(fèi)爾茨重視培養(yǎng)年輕人，她認(rèn)為自己的經(jīng)歷是“有志者事竟成”的寫照。那么這個(gè)月即將年滿56歲的她又會(huì)在盤算什么新的目標(biāo)呢？那就是10月9日的美國(guó)銀行（Bank of America，BAC）芝加哥馬拉松。雖然在2月份之前她連1英里（1.61公里——譯注）都沒(méi)跑過(guò)，但是費(fèi)爾茨目前正在積極備戰(zhàn)。周日，她在給我的郵件中說(shuō)：“上周末我跑了13.1英里”，她繼續(xù)寫道，“太熱了（有90華氏度——32.22℃）。我花了3小時(shí)12分才跑完。所以近期跑奧運(yùn)賽事是沒(méi)戲了…但是我堅(jiān)持跑完了 ”

????Jan Fields, who started at McDonald's 33 years ago cooking fries and is now the fast food chain's U.S. president, was soon to turn 55 when, she says, "I woke up one day and said, "Oh my God, how did I gain this much weight?"

????Like millions of her customers at the 14,000 restaurants she oversees, Fields added her weight gradually--"10 pounds at a time: 10, 10, 10 and all of a sudden, I looked and I said, 'Oh, my God, I've gained 90 pounds. How did I ever do that?"

????Of course, McDonald's tops critics' hit list for compounding America's obesity epidemic, but Fields insists that her own culprit wasn't food but lack of exercise. "I didn't exercise," she confesses. "I worked all the time, went home and went to bed."

????Fields, No. 25 on Fortune's Most Powerful Women list, has always been easy to underestimate: The seventh of eight children raised in tiny Vincennes, Indiana, she grew up skinny and dreamed of being a nun, then a lawyer. But she met a guy, married young, had a daughter, and was driving to an interview for a secretarial job at a construction company when, at 23, she stopped at McDonald's for a Coke and spotted a "Now Hiring" sign. It was, in fact, the first time Fields ever ate in a McDonald's. She and her husband, who had enlisted in the Air Force, were so poor that they couldn't afford to eat out.

????Accepting a job on a whim and starting at $2.65 an hour, she went home that first night and cried -- "a disaster" until they moved her from cooking fries to serving customers at front counter. "Never quit over one thing or one person," she advises. Rising rapidly through the ranks, she was propelled by a remarkable discipline and a down-home, inspirational leadership style.

????Along the way, Fields was working so hard that she never had time to get a college degree or take care of herself. Until she visited a nutritionist and committed to do something about her weight gain. "I started with going to the gym and getting on a treadmill," she says, noting that all you need is a walking path to begin a fitness routine. "I didn't hire a trainer."

????She started drinking a lot more water. And no soda, not even the diet kind. Fields still eats at McDonald's every day--but different foods and smaller portions than she used to. Breakfast is McDonald's oatmeal or an Egg McMuffin or a fruit and yogurt parfait. Lunch, at the McDonald's next to her office in Oak Brook, Illinois, is usually a grilled chicken sandwich or a cheeseburger, with a few French fries and iced tea.

????Dinner is not at McDonald's -- she does get away from work. Typically, she has pasta, or, she says, "I'm big on tomato mozzarella salad. That's my favorite all-time food."

????The focus on healthy eating has been good for Fields -- and the company. New products like smoothies and oatmeal have helped expand McDonald's customer base and profits, and the stock recently reached an all-time high. Meanwhile, McDonald's announcement last week that its restaurants will serve fruit or a vegetable with Happy Meals and cut the portion size of French fries signifies "our first step toward creating serious change," Fields says.

????Fields, who loves to mentor young people, contends that her story proves that people "can do anything that they can set their mind to." And what, as she turns 56 this month, is she setting her mind to next? The Bank of America (BAC) Chicago Marathon, on October 9. Though she never ran a mile until this past February, Fields is now training vigorously. On Sunday, she emailed me: "This past weekend, I did 13.1 miles," she wrote. "It was so hot (got to 90), it took me 3 hrs and 12 minutes. So I will not be qualifying for any Olympic trials any time soon...but I made it "
