In a US study that studied the health information of 50,000 people over seven years, researchers found that those who made breakfast the largest meal of the day were more likely to have a lower body mass index( BMI,体重指数) than those who ate a large lunch or dinner.
However, studies have shown that giving up dinner increases the risk of physical illness, according to Courtney Peterson, the study’s author at the University of Alabama at Birmingham.
“For those who eat dinner late, their risk of obesity(肥胖) and diabetes(糖尿病) goes through the roof. While it seems breakfast is the most important meal of the day, it might actually be dinner,” she says. “Our blood sugar control is best early in the day. When we eat dinner late, that’s when we’re weak because our blood sugar is the worst.”
Researchers designed a study in which 52 women took part in a 12 - week weight loss programme. All had the same number of calories(卡路里) over the day, but half had breakfast, while the other half did not. What they found was that it wasn’t breakfast itself that caused the people who joined this study to lose weight: it was changing their normal routine.
When you have been eating less and less, and the blood sugar in your body drops, your body will produce something named “cortisol(皮质醇)” that specifically has a great influence on blood sugar. But it can also create stress in the body, making you feel sad and nervous.
