Supersize Surprise

Ask anyone why there is an obesity epidemic and they will tell you that it’s al down to eating

too much and burning too few calories. That explanation appeals to common sense and has

dominated efforts to get to the root of the obesity epidemic and reverse it. Yet obesity researchers

are increasingly dissatisfied with it. Many now believe that something else must have changed in

our environment to precipitate( 促成) such dramatic rises in obesity over the past 40 years or so.

Nobody is saying that the “big two” – reduced physical activity and increased availability of food –

are not important contributors to the epidemic, but they cannot explain it all.

Earlier this year a review paper by 20obesity experts set out the 7 most plausible alternative

explanations for the epidemic. Here they are.

1.Not enough sleep

It is widely believed that sleep is for the brain, not the body. Could a shortage of shut-eye also

be helping to make us fat?

Several large-scale studies suggest there may be a link. People who sleep less than 7 hours a

night tend to have a higher body mass index than people who sleep more, according to data

gathered by the US National Health and Nutrition Examination Survey. Similarly, the US Nurses’

Health Study, which tracked 68,000 women for 16 years, found that those who slept an average of 5

hours a night gained more weight during the study period than women who slept 6 hours, who in

turn gained more than whose who slept 7.

It’s well known that obesity impairs sleep, so perhaps people get fat first and sleep less

afterwards. But the nurses’ study suggests that it can work in the other direction too: sleep loss may

precipitate weight gain.

Although getting figures is difficult, it appears that we really are sleeping less. In 1960 people

in the US slept an average of 8.5 hours per night. A 2002 poll by the National Sleep Foundation

suggests that the average has fallen to under 7 hours, and the decline is mirrored by the increase in

obesity.

2. Climate control

We humans, like all warm-blooded animals, can keep our core body temperatures pretty much

constant regardless of what’s going on in the world around us. We do this by altering our

metabolic(新陈代谢的) rate, shivering or sweating. Keeping warm and staying cool take energy

unless we are in the “thermo-neutral zone”, which is increasingly where we choose to live and

work.

There is no denying that ambient temperatures(环境温度) have changed in the past few decades.

Between 1970 and 2000, the average British home warmed from a chilly 13C to 18C. In the US, the

changes have been at the other end of the thermometer as the proportion of homes with air

conditioning rose from 23% to 47% between 1978 and 1997. In the southern states – where obesity

rates tend to be highest – the number of houses with air conditioning has shot up to 71% from 37%

in 1978.

Could air conditioning in summer and heating in winter really make a difference to our

weight?

Sadly，there is some evidence that it does-at least with regard to heating. Studies show that in

comfortable temperatures we use less energy.

3. Less smoking

Bad news: smokers really do tend to be thinner than the rest of us, and quitting really does

pack on the pounds, though no one is sure why. It probably has something to do with the fact that

nicotine is an appetite suppressant and appears to up your metabolic rate.

Katherine Flegal and colleagues at the US National Center for Health Statistics in Hyattsville,

Maryland, have calculated that people kicking the habit have been responsible for a small but

significant portion of the US epidemic of fatness. From data collected around 1991 by the US

National Health and Nutrition Examination Survey, they worked out that people who had quit in the

previous decade were much more likely to be overweight than smokers and people who had never

smoked .Among men, for example, nearly half of quitters were overweight compared with 37% of

non-smokers and only 28%of smokers.

4. Genetic effects

Yours chances of becoming fat may be set, at least in part, before you were even born.

Children of obese mothers are much more likely to become obese themselves later in life. Offspring

of mice fed a high-fat diet during pregnancy are much more likely to become fat than the offspring

of identical mice fed a normal diet. Intriguingly, the effect persists for two or three generations.

Grandchildren of mice fed a high-fat diet grow up fat even if their own mother is fed normally-so

you fate may have been sealed even before you were conceived.

5. A little older…

Some groups of people just happen to be fatter than others. Surveys carried out by the US

national center for health statistics found that adults aged 40 to 79 were around three times as likely

to be obese as younger people. Non-white females also tend to fall at the fatter end of the spectrum:

Mexican-American women are 30% more likely than white women to be obsess, and black women

have twice the risk.

In the US, these groups account for an increasing percentage of the population. Between 1970

and 2000 the US population aged 35 to 44 grew by43%.the proportion of Hispanic-Americans also

grew, from under 5% to 12.5% of the population, while the proportion of black Americans increased

from 11% to12.3%.these changes may account in part for the increased prevalence of obesity.

6. Mature mums

Mothers around the world are getting older. in the UK, the mean age for having a first child is

27.3,compared with 23.7 in 1970 .mean age at first birth in the US has also increased, rising from

21.4 in 1970 to 24.9 in 2000.

This would be neither here nor there if it weren’t for the observation that having an older mother

seems to be an independent risk factor for obesity. Results from the US national heart, lung and

blood institute’s study found that the odds of a child being obese increase 14% for every five extra

years of their mother’s age, though why this should be so is not entirely clear.

Michael Symonds at the University of Nottingham, UK, found that first-born children have

more fat than younger ones. As family size decreases, firstborns account for a greater share of the

population. In 1964, British women gave birth to an average of 2.95 children; by 2005 that figure

had fallen to 1.79. In the US in1976, 9.6% of woman in their 40s had only one child; in 2004 it was

17.4%. this combination of older mothers and more single children could be contributing to the

obesity epidemic.

7. Like marrying like

Just as people pair off according to looks, so they do for size. Lean people are more likely to

marry lean and fat more likely to marry fat. On its own, like marrying like cannot account for any

increase in obesity. But combined with others—particularly the fact that obesity is partly genetic,

and that heavier people have more children—it amplifies the increase form other causes.
