Researchers from the Johns Hopkins University School of Medicine have followed the meal-time habits of more than 500 people for six years, 【小题1】 (find) weight change is most affected by the size and 【小题2】 (frequent) of meals rather than the interval from first to last meal. The study challenges the popular trend of intermittent fasting (禁食疗法) as a useful weight loss strategy.

Intermittent fasting, also referred to 【小题3】 time-restricted feeding, is a dietary strategy where all meals 【小题4】 (consume) during a short window of time each day. These windows can span anywhere from six to ten hours, resulting in a person essentially fasting for up to 18 hours each day.

All of this, of course, doesn’t mean intermittent fasting strategies won’t help. But it seems increasingly clear that the weight loss 【小题9】 (occasion) seen with these eating strategies may be primarily driven by a 【小题10】 (reduce) caloric intake.

New research says that exposing to the smell of junk food for at least two minutes can actually help you make【小题1】(healthy) food choices.

The results of a series of experiments, including field【小题2】(study) at a supermarket and at a middle school cafeteria， show that extended exposure to junk food smell【小题3】(lead) to lower purchases of unhealthy foods【小题4】(compare) with healthy smell. The brain doesn't necessarily distinguish【小题5】a pleasurable smell and taste. That is【小题6】long exposure to junk food smell can be as satisfactory as actually having it in your mouth,【小题7】in turn decreases the desire for consumption of junk food.

However, it's not the same case with smell of healthy food. When the exposure to smell of healthy food【小题8】(examine), food choices were not【小题9】(profound) influenced. The reason for this is that healthy food is not connected with reward in our brain and therefore has little influence on【小题10】we desire.

It 【小题1】debate) for years: Are eggs good or bad for you? People who eat an added three or four eggs a week or 300 milligrams of dietary cholesterol (胆固醇) per day, have a higher risk of both heart disease and early death compared with those who eat 【小题2】 (few) eggs, new research finds.

“Eggs, 【小题3】 (special) the yolk, are a major source of dietary cholesterol,” wrote Victor Zhong. In 【小题4】 study published Friday in the medical journal JAMA 【小题5】 there are many unexpected reports, he and his colleagues noted that a single large egg contains about 186 milligrams of cholesterol. Over the follow-up period, a total of 5400 cardiovascular (心血管的) 【小题6】 (event)   occurred, including 1302 fatal and nonfatal strokes, 1, 897 incidents of fatal and nonfatal heart 【小题7】 (fail)   and 113 other heart disease deaths. An additional 6132 participants died of other causes. 【小题8】 (consume) an additional 300 milligrams of dietary cholesterol per day was associated 【小题9】 a 3.2% higher risk of heart disease and a 4.4% higher risk of early death, Zhong’s analysis of the data showed.

“Eggs are a nutritious food. While this study focuses on the amount we’re eating, it’s just as important 【小题10】 (pay) attention to how the eggs are cooked and to the trimmings that come with them,” said Taylor, who was not involved in the research.
