The diet industry and fad diets can lead friend to believe that over there is a precise time that the day to eat her meals the is best or “healthiest.”

But for most of us, the time of the day we eat our meals is figured out by myriad factors, favor our job-related schedules, our hunger levels, the drugs we take, and also even the time our family, friends, and co-workers are free to re-superstructure a meal.

You are watching: Which statement is always true about the frequency at which you eat meals?

The fluid nature the day-to-day life way that difficult to specific mealtimes every job is difficult — and some days, the just can not it is in possible. Plus, the ideal mealtimes because that you may readjust or evolve throughout her life.

Nevertheless, this doesn’t median that mealtimes nothing matter. In fact, research says that the moment of the day we eat and also the quantity of time that elapses in between meals may have actually profound effects on ours health.

Why mealtimes matter
Though plenty of of us often tend to feel like what we eat has a greater impact than when us eat, it’s important to remember the our bodies digest food in different ways at miscellaneous times the the day.

Many that these daily fluctuations are pertained to circadian rhythm, the cycle the moderates our sleep-wake trends over 24 hours. In other words, that the body’s inner clock, and it reacts mainly to alters in irradiate (1).

We usually think that circadian rhythms together affecting how worn down or awake us feel, but they also influence various other physical, mental, and also behavioral procedures in the body, consisting of eating and digestion (2).

Conversely, mealtimes influence circadian rhythm. Thus, our eat habits and also circadian rhythms continually interact, though some scientists continue to be unsure regarding exactly how much (3, 4, 5).

Still, researchers have found associations between circadian rhythm, mealtimes, weight status, and even insulin resistance, a hallmark that metabolic problems like obesity and also diabetes (6, 7, 8, 9).

In fact, repeated interruptions to typical circadian rhythms, such together those that occur when girlfriend travel between time zones or traction an all-nighter, may increase your hazard of occurring a metabolic condition (10, 11, 12, 13).

For example, a recent study that 31 police officers found that officers consumed much more calories during night shifts than day shifts. Other studies have linked night shifts with irregular enjoy the meal patterns, poorer diet quality, and rise in metabolic risk determinants (14, 15, 16, 17).


Mealtimes and digestion communicate with natural processes in the body, such as circadian rhythm. Timing meals and also digestion in a means that prevents disruption that these other processes has tendency to yield much better health outcomes.

Keeping a continuous meal schedule native day to day is connected to load loss, rise in energy, and also a palliation in metabolic risk determinants for chronic an illness (18, 19).

Still, eating at the exact same time every day may not always be doable, so it’s finest not to take a one-size-fits-all strategy to mealtimes.

What’s more, individual genetics impact much of how our bodies control circadian rhythms that communicate with mealtimes. Thus, there’s no solitary best mealtime schedule for everyone, and it might take some trial and also error to find the best mealtimes because that you (20).

Here room some indict to save in mind when scheduling her meals.


Taken literally, breakfast is the very first meal that the day during which friend break your overnight fast. Researchers still dispute just how necessary the time of that meal is.

Some people feel strongly about eating breakfast in ~ the first few hours of rising, if others prefer to wait until later on in the day as soon as their appetites are higher to have actually their very first meal. Each may have actually its own set of benefits.

A few studies discovered that skipping breakfast may impact diet quality. An ext specifically, skipping breakfast may result in eating an ext calories during lunch — and also less nutritious food in its entirety — throughout the remainder of the day (20, 21, 22, 23).

What’s more, consuming much more calories during breakfast rather than later on in the night may benefit weight loss initiatives (24, 25).

On the other hand, some research uncovered that restricting the total variety of hours in the day throughout which friend eat — particularly to 12 hrs or less — may also assist weight loss efforts and improve metabolic health in its entirety (19, 26).

Keeping a restricted meal window during the job is a form of intermittent fasting recognized as time-restricted eating.


In enhancement to eating a continuous breakfast meal, studies imply that an earlier lunch may aid people shed weight — despite it’s vital to note that separation, personal, instance genetic components are additionally at beat (27, 28, 29, 30).

Some newer research even suggests that an early lunch may add to a healthy microbiome, the collection of bacteria in the human being gut and body the have far-reaching effects on all at once health (31, 32).

All in all, keeping the bulk of her calorie intake in earlier hours the the job by having an previously breakfast and lunch may benefit weight loss and also metabolic wellness (33).


When it come time because that dinner, eating earlier in the evening and avoiding high calorie meals just prior to bedtime or throughout the night might support better health outcomes.

One research in 8,000 adults linked eating so late at night with dyslipidemia, higher levels the fat in the blood and a risk aspect for chronic disease. Rather have linked a late dinner with transforms in human body fat, weight gain, and also the body’s ability to digest sugar (34, 35, 36, 37).

These research findings frequently have to carry out with the hormone melatonin. Released at night, melatonin is among the major hormonal regulators of circadian rhythm and our sleep-wake cycles (38, 39).

As the body releases melatonin, the releases much less insulin, which inhibits its ability to digest sugars favor glucose. Thus, scheduling mealtimes too very closely to when your human body releases the hormone, especially late in the evening, is a risk aspect for chronic an illness (20, 26, 40).


Each of us has actually a unique genetic profile and also individual scenarios that dictate our day-to-day schedule and help determine the ideal times to eat. However, some research shows that eating a bulk of day-to-day calories earlier in the day may be ideal.

The finest times come eat before and after a workout count on the type of exercise you arrangement to do.

A high intensity workout or an extreme cardio session may require much more precise meal timing. On the other hand, a leisurely activity like go lends better flexibility.

For pre-workout meals, eat an hour or two prior to you exercise helps fuel your muscles. Simply remember to provide your meal sufficient time to begin digesting prior to you start any high intensity activities (41, 42).

For post-workout meals, eat within 2 hours of finishing an activity may help replenish your energy stores and repair any type of muscle protein damage that arisen during the exercise (41).

Still, scientists have actually a lot of to learn when it comes to exercise and mealtimes. Because that example, some current research says that eating prior to a workout rather than afterward may advantage blood sugar manage (43).

Other researches have discovered that some people may perform better during aerobic exercises like running while still in one early-morning state of fasting (44).

Research on this topic is quiet emerging and also sometimes contradictory, and also it might depend on an individual factors like individual health and also the form of workout. Thus, an ext studies are needed (45).


Eating 1 to 2 hours prior to a workout and also then again within 1 to 2 hours complying with exercise helps ensure that you’re both properly sustained beforehand and also adequately refueled afterward.

Though the best mealtimes will ultimately vary from person to person, there space some basic suggestions because that timing meals.

Keep these three rules of ignorance in mind once planning her mealtimes (26, 46):

Eat previously when possible. plenty of studies have connected earlier mealtimes to better health outcomes, contrasted with eating late at night. Limit your daily window of eating. maintaining your entire caloric intake because that the day in ~ a 12-hour time framework reduces the danger that digestion will certainly interfere v your body circadian rhythm.

These guidelines might be useful when do the efforts to decision upon a regular meal regime to follow.

However, you’ll likely want to take into consideration some individual determinants as well, together as:

Your day-to-day routine. We often time our meals about work schedules and an individual obligations. That may mean eating earlier or later than you would ideally favor to. In this case, keeping consistency may still aid limit interruptions to her circadian rhythm.Type that meal. on days as soon as you have actually no selection but to eat later in the evening, selecting small, nutrient-dense, yet an easy meals can assist digestion and also limit circadian valuation disruptions.Your instincts. Mealtimes will likely fluctuate indigenous day to day. It’s essential to trust your instincts and allow yourself to eat when you’re hungry, also if it’s in ~ a different time the the day 보다 you planned.SUMMARY

The best times of day come eat will differ from human to human — and also maybe even from day come day. Think about eating the mass of her calories earlier in the day, and try to stop eating within a couple of hours that bedtime.

Eating a bulk of her calories previously in the day and limiting just how much you eat later on in the night or through the overnight hours may aid your body digest her food an ext efficiently.

It may likewise reduce your risk of specific risk components for metabolic problems like diabetes and also obesity.

However, over there is no magic bullet when it concerns mealtimes. The appropriate eating schedule because that you might depend on numerous factors, including your day-to-day routine, health conditions, and genetics.

Nevertheless, by maintaining the fundamentals the mealtimes in mind while allowing yourself flexibility, you deserve to feel confident about your enjoy the meal schedule — no matter what obstacles the work throws your way.
