145.
A new study collected data that shows that people who snore are more likely to gain weight than are people who do not snore. It is well known that many people who snore also stop breathing frequently during the night for a few seconds, a condition called sleep apnea. The interruption of breathing wakes the person—often so briefly that the waking goes unnoticed—and can leave the person too tired during the day to exercise. Anyone who snores, therefore, should try to eat less than the average person and to exercise more.
正文：
   The editorial suggests that anyone who snores should try to eat less and to exercise more for lose weight. To support the suggestion, the author cites a study as the evidence. This reasoning is unsubstantiated and therefore is unconvincing.

In the first place, the author fails to give the accurate data of the study on which the conclusion relies. Perhaps the number of the sample is so limited, and it is not representative enough to draw any conclusion. Perhaps the number of the people who snore and gain more weight is just a little more to the people do not snore, for instance, in the total 100 people, 51 people who snore and gain weight to the other 49 who do not snore. And the lower this ratio, the less warranted the conclusion is.

Secondly, the author unfairly assumes that the people who gain weight easily are attributable to snore. But there is no evidence to prove that is the real case, and there are many other factors may influence the gaining of weight. It is possible that those who gain weight easily like too eat food with high energy and fat, or like to spending most of their time sitting and watching TV. Without ruling out these possible scenarios, I can't accept the author's reasoning.

In addition, even if the snore people indeed easily gain weight, the author rest on the assumption that the people who snore lacks of exercise for that those people are interrupted in sleeping caused by snore to stop breath. However, we lack the detail statistics of how many people stop breathing when snore in their sleep. The less the number is, the less convinced the assumption is. Even if snore of many people indeed interrupts their breathing. There is no evidence to show it will influence the physical condition significantly so as to let the people feel tired when exercising.

Finally, even if the foregoing assumption is credible. The author suggests anyone who snores should try to eat less and exercise more than the average person. However, common sense tells us that not every person who snores are fatter than average and need to lose weight. And there must be some people who snore are thinner than average people, and it is unnecessary for them to do so much exercise or eat less. In the contrary, what this kind of people should do is to eat more and rest more.

In sum, the author's suggestion rests on some insufficient assumption and too extreme and therefore unconvincing. To strengthen the argument, the author should give more evidences too prove the real condition. To better assess the argument, more proper proposal should be offered.
