3点后不吃东西,减肥更有效!JAMA子刊最新研究

2022-08-15 中国循环杂志 中国循环杂志

每天在早7点至下午3点之间的8小时内进食(晚上不吃),与每天进食时间窗≥12小时相比,可更有效地减重。

已有不少研究表明,限时进食,即将一天内进食时间限制在某一特定时间窗(例如8小时),有助于减重。

8月8日,JAMA内科学子刊发表的一项随机临床研究提示,在每天限制热量的基础上,尽早限时进食(early time-restricted eating),即每天在早7点至下午3点之间的8小时内进食(晚上不吃),与每天进食时间窗≥12小时相比,可更有效地减重。

这项为期14周的平行分组、随机临床研究一共纳入90名肥胖成年人(25~75岁),所有人在接受减重治疗(限制热量)的基础上,随机分入尽早限时进食组(在早7点至下午3点间进食)或对照组(进食时间窗≥12小时)。

结果显示,尽早限时进食组的体重减轻幅度明显大于对照组(6.3 kg vs. 4.0 kg),但在体脂减少方面与对照组相似(4.7 kg vs. 3.4 kg),两组的体脂与体重减轻比例差异也相似(相差-4.2%)。

尽早限时进食组的减重效应相当于每天的热量摄入额外减少了214 kcal。

在减重的同时,尽早限时进食组的舒张压明显降低(与对照组相比降低4 mmHg),患者的情绪问题也得到明显改善。

两组在心脏代谢危险因素、进食、运动和睡眠等方面的情况相似。

在包含59人的次要分析中,与对照组相比,尽早限时进食组在减少体脂和躯干脂肪方面更有效。

该研究纳入的肥胖成年人平均年龄为43岁,平均体重指数为39.6 kg/m2,80%为女士。尽早限时进食组每周平均有6天遵循限时进食规定。
