The scientists, from the Medical Research Council’s National Survey of Health and Development, have concluded it is better to avoid getting fat in the first place。
医学研究理事会国家卫生与发展调查机构的科学家得出结论,最好从开始就不要长胖。
They followed 5,362 men and women from their birth in 1946 and 20,000 from birth in 1958, measuring their weight and blood pressure and assessing their lifestyles. The researchers found both groups began gaining weight in the 1980s and have steadily increased in size ever since。
受访者中有5362人于1946年出生,另有两万人于1958年出生,研究人员自其出生后就开始跟踪调查,包括测量体重、血压,并评估他们的生活方式。研究发现,两组人群都在20世纪80年代开始增重,且此后体重持续增加。
Dr Rebecca Hardy, the council’s programme leader on body size, said: ‘Once people become overweight, they continue relentlessly upwards. They hardly ever go back down。
理事会体型研究项目负责人丽贝卡?哈代博士说:“人们一旦超重,就会不可收拾地胖下去。很难瘦回来。”
