Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, the UK, skipping the first meal of the day not only means you eat more at lunch, but also means that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex(眶额叶皮层), which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.
Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned(扫描) the brains of 21 men and women, around the age of 25.On the first day, these people skipped breakfast before the scans. On the second day, they had cereal(谷物), bread and jam as breakfast. After the scan on both days, they had their lunch.
When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast. Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods—how pleasant, how delicious something is,” Goldstone told The Guardian.

What’s life like on a deserted island?Senator(参议员) Jeff Flake of Arizona decided to find out.
The adventurous senator took a vacation from Capitol Hill and went on a four-day Robinson Crusoe Style holiday with his two teenage sons to a remote,uninhabited island in the North Pacific Ocean.
The senator and his sons,15-year-old Tanner and 13-year-old Dallin,traveled 5,200 miles from Phoenix Arizona to the island of Biggarenn. They didn’t carry any food or water.
The island is part of the Marshall Islands.It offered no basic facilities,so the Flakes had to catch and cook their own food and purify their water.Their diet was made up of coconuts,crab and fish.They captured the crab and fish themselves and cooked the food over an open fire started with a magnifying glass(放大镜).
The Flakes brought along a lobster(龙虾) trap in the hope of having some delicious treats,but lost it within the first few hours after it was attacked by a shark.They also carried two pumps to remove salt from ocean water.It took them hours each night pumping for just a few gallons of fresh water.
One of the most memorable moments of the trip,the father said,was when he and his 15-year-old son were chased by sharks after spearing(叉) a fish in the ocean.
Still,it was quite an enjoyable holiday for the senator. “For a dad it was a wonderful thing.No video games around,no television,no distractions,no texting,” Flake recalled.
