Make sure that your answers are grammatically correct. A new study finds that getting seven to nine hours of sleep per night may help you tame (驯服) your sweet tooth. Researchers at King's College London recruited "short sleepers" — people 　 　routinely sleep less than seven hours per night. The participants were trained 　 　(extend) their sleep time in many ways, such as cutting back on caffeine, reducing screen time and 　 　 (stick) to a regular bedtime each night. With the training, the short sleepers began to sleep about one hour more per night. And here's the interesting thing: They also changed their diets — without 　 　(ask). "We found that these people also reduced their intake of added sugars by about 10 grams per day," explains one of the study's authors. That's about 40 calories' worth of sugar, 　 　 is not a huge change. But 　 　time, a small, daily decline in sugary foods can make a difference. The study was published in the American Journal of Clinical Nutrition. Its findings serve up more evidence 　 　our sleep can influence our eating habits and waistlines. A study published in 2013 also found that just five days of 　 　(shorten) sleep can lead to weight gain. In that study, people 　 　(allow) to sleep for just five hours for a five-day period. They gained, on average, almost two pounds. And as reported, the timing of meals can also influence 　 　our bodies respond to all the calories we eat.
