研究人员让9名体重正常的成年人在8点至19点之间摄入3顿正餐和两顿零食,持续8周,然后让他们在12点至23点间同样用餐,再持续8周。为了控制睡眠因素,研究人员要求测试者两次都在23点至9点之间休息。
They found that when participants ate later at night not only did their weight increase, but so did their levels of insulin, glucose and cholesterol.
他们发现,当测试者吃饭时间较晚时,他们不仅会体重增加,而且胰岛素、血糖以及胆固醇的水平也会上升。
They also found that during the first eight weeks of daytime eating, participants produced a hormone which stimulates the appetite to help them feel fuller for longer.
研究人员还发现,在前8周白天进食时,测试者体内产生了刺激食欲以促进更长时间饱腹感的激素。
Namni Goel, lead author of the study, said: "Eating later can promote a negative profile of weight, energy and hormone markers - such as higher glucose and insulin, which are implicated in diabetes, and cholesterol and triglycerides, which are linked with cardiovascular problems and other health conditions."
该研究的领头人纳米•高尔称:“进食晚会对体重、能量以及激素等指标产生负面影响,比如血糖和胰岛素升高,这可能意味着糖尿病,再比如胆固醇和甘油三酯升高,可能和心血管疾病以及其他健康问题有关。”
