Overweight people eat less often: study 體重過重者用餐次數較少

Overweight adults eat less often than people in the normal body weight range, but still take in more calories and are less active over the course of the day, according to a US study.

By contrast, normal weight adults, including those who had lost a lot of weight and kept it off, ate more often.

“Most of the research has shown that people who eat more frequently have a lower weight. But no one knows why,” said lead researcher Jessica Bachman, an assistant professor in the department of Nutrition and Dietetics at Marywood University in Scranton, Pennsylvania.

More than 60 percent of US residents are obese or overweight, but the relationship between the number of meals people eat each day and the ability to maintain weight loss has remained unclear, she said.

Bachman and her team followed about 250 people for a year, analyzing data collected in two large studies sponsored by the National Institutes of Health. One looked at the eating habits of people with a body mass index (BMI) between 25 to 47. On average, the normal weight subjects ate three meals and a little over two snacks each day, whereas the overweight group averaged three meals and just over one snack a day.

根據美國研究,過重成年人的用餐次數,通常比體重在正常範圍的人少,但仍攝取較多卡路里,在一天中也較不活躍。

相較之下,正常體重的成年人,包括曾減去很多體重而且保持下去者,通常用餐次數較頻繁。

主要研究者、賓州斯克蘭頓的馬利伍德大學營養膳食學系助理教授潔西卡.巴克曼表示:「多數研究顯示,吃東西次數較頻繁者,體重較輕,但沒人知道為什麼。」

她說,美國超過六成居民過胖或過重,但還不清楚用餐次數與維持減重能力之間的關聯。

巴克曼與團隊追蹤約兩百五十人一年,分析從國家衛生研究院所贊助的兩份大型研究取得的數據,其中一份觀察身體質量指數(BMI)在二十五到四十七之間的人的飲食習慣。正常體重的樣本,平均每天吃三餐,吃兩份多一點的零食,過重族群則是平均每天三餐,外加一份多的零食。
