The book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic (频率突增)—and How We Can End It by Deborah Cohen, a senior natural scientist, is very popular now. 【小题1】 But according to this book, the following are some misunderstandings of obesity or being overweight.

1.If you’re obese, blame your genes.

【小题2】 Between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2.If you’re obese, you lack self-control.

Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. 【小题3】 Even the most vigilant (警觉的) people may not be good controllers of themselves.

3.【小题4】

Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, and that about 65 percent of the nation’s population are obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4.The problem is not that we eat too much, but that we don’t exercise.

Michelle Obama’s “Let’s Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. 【小题5】 In fact, although a drop in work-related physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.
