    Maybe a lot of thin people will be worried about their health if the inside fat matters.

    Some doctors now think that the inside fat around important organs like the heart or liver could be as dangerous as the outside fat which can be noticed more easily.

    "Being thin doesn't surely mean you are not fat," said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have tested nearly 800 people with MRI to create "fat maps" showing where people store fat.

    According to the result, people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits (堆积物) of inside fat, even if they are thin.

   Even people with normal Body Mass Index (体重指数) scores can have surprising levels of fat deposits inside. Of the women, as many as 45 per cent of those with normal BMI scores (20 to 25) actually had too high levels of inside fat. Men were nearly 60 per cent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the stomach first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of inside fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that inside fat does harm to the body's communication systems.

    The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits. "If you want to be healthy, there is no other way. Exercise has to be an important part of your lifestyle," Bell said.

Better hygiene (卫生) habits can help you stay healthy

According to the World Health Organization, 60 percent of people's health problems are related(与…相关) to everyday hygiene habits. As the COVID-19 spreads across the world, governments and organizations in many countries have suggested that people should pay more attention to their daily hygiene practices.

In China, for example, people usually share dishes together at the dining table. But this habit has a high risk of spreading diseases through saliva(唾液). To fight against COVID-19, many cities in China, including Beijing, Shanghai and Guangzhou, have called on people to order separate(分开的)meals or use serving chopsticks(公筷) to take their food. Many people also suggest that Chinese should continue these habits after the outbreak.

In the US, the Centers for Disease Control and Prevention has asked people to develop healthy hygiene habits. For example, people should cover their mouth and nose with a tissue when they cough or sneeze.

    According to a survey by YouGov, a British market research company, many Americans have taken action to change their daily habits in the face of COVID-19.
