Weight-reducing favorable environmental protection A fat person has many every year to arrange a ton of carbon dioxide

The scientist thinks that it is a key factor in the fight of reducing greenhouse gas emissions too to keep slim. (materials picture) Keep the slim stature being not only useful to one's own health, but also help to protect the earth environment. This is a British scientist, according to the conclusion that can worked out newly.

London University subsidiary institute - -London hygiene and tropical medical researcher of institute find weight overweight person no matter take or walk respect emit more greenhouse gas than tight people, average to discharge 1 more ton of carbon dioxide than thin people every year, thus cause greater destruction to the environment. This research is issued on the latest " international epidemiology monthly magazine ".

Fat people consume oldly

Hygiene and researcher Phil and Edwards and Ian and Roberts of the tropical medical institute of London are pointed out in the thesis, grain-production is an important factor which causes the global warming. Population is larger than the consumption of the grain of fat country, there will be more greenhouse gas produced.

In with the same population base cases, look like Vietnam the population thinner country this kind 40% people whether overweight country of population take in 20% of the grain less averagely almost than look like U.S.A. generally, thus produce less greenhouse gas. Meanwhile, greenhouse gas emissions relating to traffic will be reduced too, because carry thin people and consume less energy, and fat people incline to take the car and go out even more.

The researcher estimates, 1 billion thinner population is every younger than 1 billion fatter population to produce 1 billion tons of gas of greenhouse - -Carbon dioxide. It is average that this means each fat person to discharge 1 more ton of carbon dioxide than thin people every year.

One before European Union discovers, each citizen of European Union is average to discharge greenhouse gas and reach 11 tons every year.

The hygiene of London and researcher of the tropical medical institute also find, almost average physique index (BMI) of people of every country on the earth Rising. Took Britain as examples, among 1994 - 10 years of 2004, Britain's male average BMI index was improved from 26 to 27.3, but British women's average BMI index is improved from 25.8 to 26.9, that is to say, British women are 3 kilograms equally fatter among 10 years. BMI index is the commonly used human body's fat thin intensity of measurement in the world at present and a healthy standard.

In the seventies of last century, had only 3.5% people who were overweight in the British adult population, this proportion was regarded as normal proportions of people. However, the scientist predicts, by 2010, the population of being obese of Britain will account for 40% of total population.

It influences environmental protection that fat

Constantly Britain population who is fat is meaning Britain consumed 19% of the grain more than 40 years ago, this means and compares 40 years ago at the same time, Englishmen emit 60 million tons of carbon dioxide more every year.

"In consumption of grain, get about with the fat body just as driving a car which consumes the oil. " Phil and Edwards and Ian and Roberts point out in the thesis, " the health is the heavier, difficult to move, the more rely on the car. It is not only useful to health to keep slim, is but also favorable to the environment. The mankind needs to do a large amount of work in order to reverse the global trend which become fat, need, realize fat mankind in greenhouse gas emissions of reducing, reduce, get a breathing space key factor in the fight changed to wait. " (such as being good)

BMI physique index

BMI( Bodymassindex) Refer to the body performance figure, it is a daily tool which assesses weight and height proportion, it is the commonly used human body's fat thin intensity of measurement in the world at present and a healthy standard.

The calculation formula of BMI is:

BMI =Weight (kg) /Height (m) The square of

World Health Organization thinks, as to 18 to the 65 -year-old person (except the athletes with vigorous pregnant woman, women breast-feeding their children, old man and figure) ,Can judge whether a person is fat according to the following standards:

BMI value is fewer than 18.5 o'clock, thin;

BMI is at 18.5- 24.9 o'clock, normal;

BMI is at 25- 30 o'clock, overweight;

BMI exceeds 30, it is fat.
