Can skipping dinner help you lose weight?
    2021-04-26  08:53    Shenzhen Daily

If your phone needs a software upgrade, you would likely run the installations when it’s fully charged. Otherwise, your phone and its software would take longer to sync.

A new study finds human energy systems operate in a similar fashion: Our metabolisms likely function best in the morning when our bodies are fresh and fully charged.

The research, based on a seven-year dietary analysis of 50,000 adults, found that body weight, measured by body mass index, corresponds with when we eat and how often we eat.

Specifically, people who eat larger breakfasts and adopt an 18-hour overnight fast, say from 1 p.m. to 7 a.m., have the lowest body weights. Those who ate more than three meals, or three meals plus snacks, had higher BMIs.

Those who ate later in the day, after 6 p.m., compared to having the largest meal at breakfast or lunch, had higher body weights.

The Loma Linda University researchers hypothesize that 18- to 19-hour overnight dietary fasts reboot our metabolisms to help our bodies burn calories efficiently.

Lead author Hana Kahleova, director of clinical research at the nonprofit Physicians Committee, says this process ensures our energy intake correlates with energy output, instead of energy reserves — or enlarged fat cells.

Contrary to popular belief, these extended overnight fasts seem to help boost metabolic function.

Kahleova also finds meals consumed in the evening, compared with those eaten in the morning, result in a hyperglycemic response, or elevated blood sugar, which happens when insulin can’t process glucose into energy. Like a clog in a machine, extra glucose slows down our bodies’ metabolic process.

Depending on your goals and health status, you may consider rearranging your meals so you consume more calories in the morning when insulin function is most efficient.

So, let’s say you consume 1,500 to 1,800 calories a day. Instead of splitting 500 to 600 calories evenly at each meal, you could experiment with eating 600 to 700 calories for breakfast, 600 to 700 calories for lunch and a light 300- to 400-calorie dinner.

If you’re looking to lose 10 pounds or reverse the early stages of Type 2 diabetes, the 18- to 19-hour overnight fast might work well for you. This could mean eating a larger breakfast, a medium-sized lunch and no dinner at all.

【身体质量指数】BMI shēntǐ zhìliàng zhǐshù a person’s weight in kilograms divided by the square of height in meters

如果你的手机需要升级软件,你应该会在手机完全充电后再安装。否则,手机和软件同步会耗费更长的时间。

一项新的研究发现,人体内的能量系统也在以相似方式运作。人体的新陈代谢在清新而充沛的早晨可以发挥出最佳效能。

在对5万名成年人长达7年的饮食分析的基础上,研究发现体重指数(BMI)与进食时间和进食频率相关。

具体而言,早餐吃得多、18小时

(下午1点—早上7点)空腹的人,体重指数最低。一天吃三顿以上,或者三餐加零食,体重指数会更高一些。

那些在下午6点以后进食的人比早餐或午餐吃得很多的人体重指数要高。

洛马林达大学的研究员们假设,18-19小时空腹可以重新发动人体的新陈代谢,以帮助高效燃烧卡路里。

这项研究的第一作者,非营利性医师委员会临床研究主任Hana Kahleova表示,这一过程确保摄入的能量与消耗直接相关,脂肪不会被储存或增加。

与普遍流行的观点相反,长期的夜间断食似乎有助于促进新陈代谢。

Kahleova还发现,与早餐相比,晚餐会让血糖升高更明显(胰岛素无法将葡萄糖转换为能量)。如同机器堵塞,额外的葡萄糖会降低人体的新陈代谢速度。

你可以根据你的目标和健康状况,考虑一下重新安排你的膳食。你可以在早晨胰岛素效能最高时,摄入更多的卡路里。

假设你每天摄入1500-1800卡。你可以试一下早餐600-700卡、午餐600-700卡、晚餐300-400卡,而不是每餐500-600卡平均分配。

如果你想减重10磅或处于2型糖尿病早期,18-19小时的隔夜断食也许会很有帮助。可以选择更丰盛的早饭,中等分量的午饭,并且不吃晚饭。
