科普你：关于肥胖你不知道的20件事

1. They’re doing something right out West. Sixty-six percent of Americans are overweight or obese, with the national obesity rate doubling between 1976 and 1999. But as of 2007, California was the only state not getting any fatter.
肥胖问题正在西方国家肆虐横行。65%美国人超重或肥胖，从1976年到1999年，全国肥胖率翻了一倍。2007年，全美只有加利福尼亚州人口没有增胖。

2. The root of the problem? Depending on gender and how active they are, adults should eat 2,000 to 3,000 calories per day. U.S. agriculture now produces 3,900 calories of food per inhabitant per day.
症结何在？肥胖程度因性别及个性而不同。成人每天需消耗2000-3000卡路里能量。而当下美国农业的产出为每天人均3900卡路里。

3. People who regularly eat dinner or breakfast in restaurants double their risk of becoming obese.
常在餐馆解决早晚餐的人，发胖率是正常人两倍。

4. Being overweight reduces a woman’s chances of getting pregnant.
肥胖会降低女性怀孕率。

5. The National Institutes of Health believes obesity is one of the reasons why the fastest-growing group of women experiencing infertility are those under 25.
国家卫生院表示，肥胖是引起越来越多25岁以下女性不孕不育的症候之一。

6. We’re trying. Each year nearly $50 billion is spent on diet programs.

7. People who lose just 10 percent of their weight report significant improvement in their sex lives.
成功减轻10%体重的人表示，他们的性生活也大有提高。

8. Biology is trying to help too. Leptin is a hunger-slaking hormone pumped into the bloodstream by fat cells. The more fat you have, the more leptin you make and the less hungry you feel.
生物界也一直在努力。“瘦素”是一种能延缓饥饿感的基因，可通过脂肪细胞注入人体血液。脂肪越多，容纳的瘦素就越多，饥饿感也就越少。

9. Want to get your hands on some leptin? The hormone never panned out as a diet aid because most overweight people have become insensitive to it.
你是不是也想注入瘦素呢？可惜瘦素还不及节食援助奏效，因为大部分肥胖的人早已对瘦素麻木了。

10. Over the course of a year, about 10 percent of an adult’s fat cells die. Alas, the body promptly replaces them.
每年，成人体内约有10%的脂肪细胞会消亡。可惜，新陈代谢很快又能跟上来。
