早餐吃飽、晚餐吃少有助于減肥

上班族的早餐總是吃得匆匆忙忙，而晚上又少不了聚餐宵夜。如果時間充裕，就會使人禁不住大吃一頓。研究表明，如果不想讓體重飆升，人們應(yīng)該在早餐吃最飽，晚餐吃最少。

Eating a big breakfast could help you burn double the amount of calories than if you eat a larger meal at dinner.

與一頓豐盛的晚餐相比，吃一頓豐盛的早餐可以幫助你燃燒兩倍的卡路里。

It could be the key to losing weight while also keeping blood sugar levels steady， researchers at Lübeck University in Germany said.

德國呂貝克大學(xué)的研究人員稱，這可能是幫你減肥，同時也能保持血糖水平穩(wěn)定的關(guān)鍵。

Their study found filling up in the morning boosts a metabolism process known as diet-induced thermogenesis （DIT）.

研究人員發(fā)現(xiàn)，早上吃飽可以促進(jìn)新陳代謝過程，也就是所謂的食物誘導(dǎo)產(chǎn)熱（DIT）。

DIT refers to the number of calories the body expends to heat the body and digest food. It was shown to be twice as high for those who ate more at breakfast than at dinner.

食物誘導(dǎo)產(chǎn)熱指的是身體為保暖和消化食物而消耗的熱量。研究表明，與晚餐吃得多的人相比，早餐吃得多的人食物誘導(dǎo)產(chǎn)熱是其兩倍。

On the other hand， a low-calorie breakfast increases appetite， especially for sweets， the researchers admitted.

另一方面，研究人員承認(rèn)，低卡路里的早餐會增加食欲，尤其是對甜食的渴望。

The findings published in the Journal of Clinical Endocrinology and Metabolism were based on a laboratory experiment of 16 men.

共有16名男性參加了這項(xiàng)實(shí)驗(yàn)，研究結(jié)果發(fā)表在《臨床內(nèi)分泌與代謝雜志》上。

They consumed a low and high calorie breakfast and dinner one day—and then vice versa on another.

他們在一天中分別攝入低卡路里的早餐和高卡路里的晚餐，而在另一天則相反。

The study also showed increases in blood sugar and insulin concentrations， caused by eating a meal， was diminished after breakfast， but not so much after dinner.

研究還表明，吃飯時升高的血糖和胰島素濃度在早餐后有所降低，但在晚餐后則下降沒有那么明顯。

The results also showed eating a low-calorie breakfast caused sweet cravings with a higher appetite.

此外，吃低卡路里的早餐會導(dǎo)致對甜食的食欲增加。

This suggests those saving all their calories for the end of the day may face consequences because they snack more.

這表明，想減肥的人們把一天中高熱量的食物都留到晚上會得不償失，因?yàn)樗麄冊谝惶熘袝愿嗔闶场?/p>

Corresponding author Dr Juliane Richter， a neurobiologist at Lübeck University， said， “Our results show a meal eaten for breakfast—regardless of the amount of calories it contains—creates twice as high diet-induced thermogenesis as the same meal consumed for dinner.”

通訊作者、呂貝克大學(xué)的神經(jīng)生物學(xué)家朱利安·里克特博士說：“我們的研究結(jié)果表明，不管早餐含有多少卡路里，早餐的食物誘導(dǎo)產(chǎn)熱是等量晚餐的兩倍?！?/p>

“This finding is significant for all people as it underlines the value of eating enough at breakfast，” added Dr Richter.

The study adds to increasing evidence that the best way of losing weight is to eat your largest meal in the morning—and your smallest in the evening.

越來越多的證據(jù)表明，最好的減肥方法是早上吃最飽，晚上吃最少。

Dr Richter said， “Eating more at breakfast instead of dinner could prevent obesity and high blood sugar.”

里克特博士說：“早餐多吃，晚餐少吃，可以預(yù)防肥胖和高血糖?！?/p>

Both obesity and high blood sugar can lead to a host of life-threatening illnesses including cancer， cardiovascular disease and diabetes.

肥胖和高血糖都會導(dǎo)致許多危及生命的疾病，包括癌癥、心血管疾病和糖尿病。

Previous research has shown DIT is lower in people with obesity. Its seen as a measure of how well our metabolism is working.

此前研究表明，在肥胖人群中，食物誘導(dǎo)產(chǎn)熱更低。食物誘導(dǎo)產(chǎn)熱可以衡量人體的新陳代謝。

DIT can differ depending on mealtime and is generally slower in the evening and at night due to our body clocks.

食物誘導(dǎo)產(chǎn)熱的能力因進(jìn)餐時間而異，受人體生物鐘影響。一般來說，食物誘導(dǎo)產(chǎn)熱速度在晚上會更慢。

Dr Richter said， “We recommend that patients with obesity as well as healthy people eat a large breakfast rather than a large dinner to reduce body weight and prevent metabolic diseases.”

里克特博士說：“我們建議肥胖癥患者和健康人吃一頓豐盛的早餐，而不是一頓豐盛的晚餐，這樣可以減輕體重，預(yù)防代謝疾病。”

A study of over 50，000 adults， which found eating a big breakfast， medium lunch and small dinner led to lower BMIs （body mass indexes）.

一項(xiàng)針對5萬多名成年人的研究發(fā)現(xiàn)，早餐吃得多、午餐吃適量、晚餐吃得少，會降低身體質(zhì)量指數(shù)（BMI）。

The US and Czech nutritionists tracked the participants for seven years and discovered eating the largest meal in the morning was among the most effective strategies for preventing long-term weight gain.

美國和捷克的營養(yǎng)學(xué)家對參與者進(jìn)行了7年的跟蹤調(diào)查，發(fā)現(xiàn)早上吃最飽是預(yù)防長期體重增加最有效的方法之一。

Professor Daniela Jakubowicz， author of The Big Breakfast Diet， found that those who piled on the calories in the morning were more likely to feel satisfied， preventing snacking throughout the day.

《豐盛的早餐》一書的作者丹妮拉·亞庫伯維茲教授發(fā)現(xiàn)，那些早晨攝入大量卡路里的人更容易感到滿足，從而避免了一整天都吃零食。

And another study by Professor Jakubowicz found that eating chocolate in the morning， when our metabolism is at its highest， prevented cravings for sweet things later on.

亞庫伯維茲教授開展的另一項(xiàng)研究發(fā)現(xiàn)，在早上新陳代謝最旺盛，這時吃巧克力，可以防止之后想吃甜食。
