Sleep can help weight loss by suppressing obesity genes

suppress:抑制する; 抑制
obesity:肥満

Enjoying sufficient night sleep helps weight loss by affecting the expression of genes involved in body weight control, US researchers say.

Plenty of studies in recent years have linked lack of night sleep and obesity but none of them said how sleep influences body weight.

link: 連結する,結合する 〈up,to‐gether〉

A team at the University of Washington Sleep Center in Seattle studied 1,088 pairs of twins and discovered a complex interaction between sleep and genes associated with body weight control.

interaction:相互作用,相互の影響 〔between,with〕
associate:提携する,連携する,連合する 〔with〕; 〔…に〕協同する 〔in〕

Their findings revealed that the genetic influence on body mass index (BMI) was doubled in people who slept less than seven hours per night.

BMI:肥満度指数

“The results suggest that shorter sleep provides a more permissive environment for the expression of obesity related genes,” SAID Lead author Dr. Nathaniel Watson. “Or it may be that extended sleep is protective by suppressing expression of obesity genes.”

permissive:寛大な,寛容な.

The genes affect how the body uses energy, how fat is stored, how quickly sugar is used up and the feeling of being full after a meal, wrote researchers in the journal Sleep.

The study does not mean that people may lose weight just by sleeping. Sufficient physical activity and a balanced diet have a crucial role in weight control, but the findings suggest that sleeping as much as recommended by scientists may considerably help weight loss efforts.

crucial:決定的な; (きわめて)重大な,重要な
considerably:かなり, 相当に

The study also warns about the negative effects of modern life on the average time people spend for sleeping and refreshment.

“Modern society with its ubiquitous technology often can cause misalignment between sleep need and sleep actualization,” they noted. “This frequently has adverse consequences for cognitive (mental) function and metabolic, cardiovascular, and immunologic health.”

ubiquitous:(同時に)至る所にある,遍在する
misalignment:ずれ、整合不良
actualization:具体化
adverse:逆らう,反対の; 〔…に〕反対で,反して 〔to〕
consequence:(続いて起こる,または必然的な)結果,成り行き
cognitive:認識[認知]の
metabolic: (新陳)代謝の
cardiovascular:心臓脈管; 心臓血管; 心臓脈管系; 心血管; 心臓血管性
immunologic:免疫学的; 免疫


“Indeed, over the past century habitual sleep duration has dropped 1.5 hours per night and since 2001 the percentage of US adults getting at least eight hours of sleep per night on weeknights has fallen from 38 per cent to 27 percent.”

habitual: 習慣的な,いつもの
duration:持続(期), 存続(期間)
