A New Study Says When You Eat Is More Important Than When You Sleep

  1. After-hours meals have been linked to increased stress and clotting risks — even with the same amount of sleep.

    Key Points
    • A new study from Mass General Brigham found that eating only during daytime hours significantly reduces cardiovascular risk factors, such as elevated blood pressure and clotting protein levels.

    • The researchers used a tightly controlled lab setting to eliminate outside influences, making meal timing the only variable and directly linking nighttime eating to negative heart health outcomes.

    • The study found that eating in both the daytime and nighttime increased stress and clotting risks, while daytime-only eaters had better heart metrics.

    Timing is everything. And according to a new study by scientists at Mass General Brigham, that includes when you eat your food for optimal heart health, too.


    On April 8, researchers published their findings in the journal Nature Communications, assessing whether limiting meals to daytime hours could protect heart and blood vessel health, especially for those who are awake or asleep during irregular hours — such as night shift workers, individuals with sleep disorders, or frequent travelers across time zones.

    To reach their conclusion, the team conducted a carefully controlled lab study, splitting 20 healthy volunteers into two groups: a control group that ate their meals both during the day and at night to replicate real-world shift workers and their usual eating schedules, and an intervention group that only ate during the day. The participants took part in the study for two weeks, during which they had no access to windows, electronics, or watches, ensuring their bodies had no clues about the time of day.

    Part of that time was spent on a “forced desynchrony” schedule, meaning each “day” lasted 28 hours instead of the usual 24. They also went through two special “constant routine” periods, one lasting about 32 hours and the other about 40 hours, during which they stayed awake, reclined in a dimly lit room, and had hourly snacks — which does sound suspiciously like a typical workday these days.


    Then, they were asked to participate in "night work." Throughout the study, both groups maintained the same nap cycle to ensure they all had the same sleep cycle to measure against. This means the only difference between the two groups was their eating times.

    "Our study controlled for every factor that you could imagine that could affect the results, so we can say that it's the food timing effect that is driving these changes in the cardiovascular risk factors," Sarah Chellappa, MD, MPH, PhD, an associate professor at the University of Southampton, and lead author for the paper, shared in a statement.

    I stopped reading at "a new study". :)

    What did it say?
     
  4. It said that it was a new study.

    Trivial news.

    There are actually thousands and thousands of new studies
    written by very smart health 'expert' writers out there on the internet.
    Enjoy your reading.
