Weight loss is still incredibly challenging for most people, as evidenced by the growing global obesity epidemic.
據證據表明全球肥胖現象正在日益蔓延,對於大部分人來說，減肥仍然是一項艱鉅的挑戰，。
According to the latest Centers for Disease Control and Prevention statistics, more than two in three US adults are considered overweight (defined as a body- mass index between 25 and 30), and 36.5% of US adults fall into the obese category (BMI greater than 30).
根據疾病控制和預防中心的最新資料統計，超過三分之二的美國成年人屬於超重(身體質量指數在25到30之間)，而36.5%的美國成人已經進入肥胖範疇(體質指數大於30)。
Many people also want to lose weight. According to a recent study in the Journal of the American Medical Association, approximately half of overweight and obese adults report that they are trying to lose weight. Which is why my patients often ask, "Why aren’t I losing weight?"
許多人也想減肥。《美國醫學會雜誌》最近的一項研究表明，大約一半的超重和肥胖人群說他們正在盡力減肥。那麼我的病人們經常就會問：“為什麼我沒有減肥成功?”
There is no simple, universal answer to this question, but after nearly two decades of working with patients trying to lose weight, and with the help of two leaders in the field of nutrition and obesity medicine, I’ve put together this list of some of the most common behavioral and medical reasons you might not be losing weight, even though you think you are doing everything right. I’ve also tried to include suggestions to get you on the right track to sustained weight loss.
這個問題並沒有一個簡單而通用的答案，但是經過對那些盡力在減肥的病人長達近二十年的研究，以及兩位營養學和肥胖醫學界領軍人物的協助下，我列出了一些可能導致你減肥失敗的最常見的行為和醫藥方面的因素，儘管你可能認為自己沒做錯什麼。我還盡力為你提供了建議來幫你走上減肥成功之路。
You have calorie ’amnesia’
你有熱量“失憶症”
This is one of the most common and easy-to-fix issues that I see in my practice: Put simply, people often eat more calories than they realize.
這是我在實踐中看到的最常見的，也是最容易解決的問題之一：簡單來說，人們通常攝入的熱量要比他們意識到的要多。
You relax your diet too much on weekends
你在週末太過放縱飲食了
This is another very common issue that is a bit more challenging to fix, as weekends are generally much less structured and more social than weekdays. Three days (Friday, Saturday and Sunday) of more relaxed eating (and in many cases drinking) can easily erase four days of more focused effort.
這是另一個很常見的問題，但是有點兒難以解決。因為週末相比工作日，缺少結構體系，而更偏向社會化。三天(週五，週六和週日)的大吃大喝(在很多情況下)很容易就將你前四天努力的成果抹除掉了。
Your medication is working against you
藥物對你沒什麼好處
Most physicians do not receive adequate training in obesity medicine and nutrition. Many may not be aware that the medications they prescribe may lead to weight gain or make weight loss more challenging.
在肥胖醫學和營養學方面，大多數內科醫生都沒有接受足夠的訓練。他們中許多人可能還沒意識到他們開的藥物可能會導致體重增加，或者使減肥變得更難。
You eat too much of a good thing
你好東西吃太多了
It is true that recommendations concerning dietary fat have changed in the past decade, and nutrition science has found that unsaturated fat, including nuts, seeds, avocado and olive oil, plays an important role in a healthy diet.
確實，關於飲食中脂肪方面的'建議在過去十年裡已經發生了改變，營養科學表明，不飽和脂肪，包括堅果、種子、鱷梨和橄欖油，在健康飲食中起著重要作用。
However, you can easily eat too much healthy fat along with other healthy foods, including whole grains.
然而，你很容易就會在吃其他健康食物的同時攝入過多的健康脂肪，包括全穀物類食物。
Your body is resistant to insulin
你的身體對胰島素有抵抗作用
This is an issue I often encounter with patients and one that my colleague Dr. Michael Rothkopf, president of the National Board of Physician Nutrition Specialists, confirms is an often overlooked reason for weight loss failure.
這是我在病人身上經常遇到的一個問題，而我的同事，全美營養醫師專業委員會主席邁克爾·羅特科普夫博士也證實，這是一個經常被忽視的導致減肥失敗的原因。
