Therefore, ingested glucose and fats are not burned for energy, but rather end up being stored as fat. If dinner is eaten earlier, metabolism remains active until sleep time and less fat ends up being stored.

This study would seem to corroborate the benefits of the daily time-restricted fast since if no food is eaten after late afternoon, the reduced metabolism associated with sleep is less of an issue because most of the food will have been metabolized in the 5 or 6 hours between the last meal and sleep.

Now, just as I was ready to wrap things up with a final praise of intermittent fasting schemes, I learned of two recently published papers in respected journals. One found that in adults over the age of 40, a time interval of fewer than 4.

The second study asked participants to use an app to record the timing of their meals and then went on to relate this to their body weight as documented in their medical records over a ten-year period.

Weight changes were not associated with the time between the first and last meals, which would seem to argue against trying to lose weight by time-restricted eating. Where does all this leave us? As is the case with almost every aspect of nutrition there is controversy, and studies can be found to back up each side.

Separating the wheat from the chaff is challenging and requires an extensive review of studies to try to get a handle on the preponderance of evidence. At this point, that evidence indicates caloric restriction to be a factor in reducing markers of disease and longevity, but to make recommendations, especially ones that are difficult to institute, we need more than markers.

We need long-term human trials, with a significant number of subjects that compare regular diets, reduced calorie diets, and intermittent fasting with end points of disease or death. Such lengthy trials are difficult if not impossible to finance, organize and monitor.

In their absence, we are reduced to making educated guesses. Since none of the calorie-restricted regimens has shown any risk, there seems to be no harm in giving one or another a shot, whether it be for weight loss or just enhanced health and perhaps a longer life.

But I suspect most people would not be able to endure calorie restriction over the long term. There is just too much pleasure to be had from eating. However, having an early dinner and then fasting until bedtime may be a challenge that can be met and may be worth a try. At least until the next study comes out telling us that life expectancy in Spain, where dinners are traditionally eaten late at night, is longer than in North America.

Obviously, the field of nutritional research is very fertile and there are many plants to harvest, but we do have to watch out for the weeds. McGill University Office for Science and Society Separating Sense from Nonsense.

In addition to the flexibility and freedom that this plan offers, TRE also touts a long list of possible health benefits, ranging from increased longevity to weight loss , improved blood sugar control , and more.

We reached out to a few of the top experts on time-restricted eating to understand how it impacts your health, who it might be a good fit for, and how you can find a schedule that works for you. Time-restricted eating is a form of intermittent fasting that involves limiting your food intake to a specific window of time each day.

In most cases, people will limit their food intake to a six- to hour slot and fast during the remaining hours outside of this time period.

Though some people limit their intake during fasting periods to water only, others may choose to opt for calorie-free beverages, like black coffee or tea, or eat a small number of calories. In recent years, TRE has soared in popularity thanks to the unique flexibility that it offers.

Contrary to other diet plans that focus on meticulously measuring grams of carbs, fat, or protein , TRE doesn't require you to log your food intake and enables you to eat whatever you choose within a specific time period each day.

Plus, TRE doesn't make you majorly restrict calories like other forms of fasting such as alternate-day fasting ADF , one meal a day OMAD , and fasting. Emerging research shows that time-restricted eating has a number of potential benefits, ranging from enhanced longevity to increased weight loss and a reduced risk of chronic disease.

Here, we take a deep dive into the science behind each:. According to Humaira Jamshed, Ph. In one study conducted by Jamshed and her colleagues, participants followed an early time-restricted eating plan for four days, which involved limiting their food intake to the hours of 8 a.

each day. By the end of the study, researchers observed increased markers of autophagy 1 , suggesting that TRE could potentially have anti-aging effects. Researchers in this study concluded that TRE could reduce inflammation and other age-related changes, resulting in enhanced longevity.

While it may sound too good to be true, this found in a pilot study 4 conducted by Gabel and other researchers. The study found that, on average, people who limited their food intake to an eight-hour period each day consumed calories less per day and lost 2. Jamshed notes that TRE may also help regulate levels of ghrelin and leptin, two hormones involved in regulating hunger and satiety.

Interestingly, one study found that early time-restricted eating increased feelings of fullness, decreased the desire to eat, and reduced levels of ghrelin the "hunger hormone" , all of which could potentially boost weight loss 5.

In addition to supporting weight loss, TRE may promote other aspects of metabolic health as well. Jamshed adds that it may help reduce insulin resistance 6 and increase insulin sensitivity, which can improve your body's ability to use insulin to regulate blood sugar levels effectively.

A recent review by Gabel and colleagues theorized that the benefits of TRE could stem from its ability to 6 stimulate autophagy, reduce oxidative stress, and increase the responsiveness of insulin-producing cells in the pancreas.

There are several simple ways to integrate TRE into your day. Here are some sample schedules for the most popular methods, along with a few of the key pros and cons to consider for each. Early TRE usually restricts food intake to a period earlier in the day and involves fasting in the early afternoon.

Sticking to an early eating schedule may help you get the most bang for your buck, according to Jamshed. This is also reflected in multiple studies, which have linked an early time-restricted eating schedule to improved insulin sensitivity 8 , decreased oxidative stress 8 , increased weight loss 9 , and reduced blood pressure levels 9.

However, this plan may be challenging to stick to, especially as it involves forgoing family dinners, happy hours, and late-night snacks. It might also not be a good fit if you sleep in or prefer eating your morning meal a bit later in the day.

Midday TRE involves limiting your food intake to the middle of the day, often by skipping breakfast and eating an early lunch. However, it may not align with your natural circadian rhythms as well as early TRE, she says, which could diminish some of the possible benefits.

In fact, one study comparing the two methods found that early TRE was more effective at improving insulin sensitivity 10 than midday TRE. Early TRE was also associated with reductions in body weight, fasting blood sugar levels, and inflammation, whereas midday TRE was not.

Jamshed states that this could be a good option for people who prefer to socialize or eat dinner later in the day, noting that it may still offer some of the benefits of TRE.

In fact, a recent trial 11 comparing early and late TRE found that both resulted in similar amounts of weight loss compared to a control group. However, early TRE still had an edge over late eating, especially in terms of its effects on blood sugar, blood pressure, fasting insulin, and insulin resistance.

According to Jamshed, late TRE may not be ideal for blood sugar control and fat burning, as our body's sensitivity to insulin tends to decline 12 in the evening.

may have more benefits for glucose control," says Gabel. Jamshed agrees, noting that early TRE may be the most effective option when it comes to metabolic health, weight loss, and mood. However, both also acknowledge that this eating pattern may be harder for some people to follow, as many people prefer socializing in the evenings and enjoying dinner with family or friends.

Jamshed emphasizes that there's no single "best" type of TRE for everyone, as the most appropriate option can vary depending on many individual factors. Ultimately, it may be best to tailor your eating pattern to your individual schedule and experiment with the precise timing to find what works for you.

And as far as how long to fast, if you're new to time-restricted eating, consider checking out and fasting plans, both of which involve abstaining from food for 18 or 16 hours each day, respectively. While there's no one-size-fits-all plan when it comes to time-restricted eating, these are two of the most popular and beginner-friendly variations.

Though TRE may offer several possible health benefits, it's not a good fit for everyone. Gabel states that intermittent fasting in general is not recommended for children, adolescents, people with a history of eating disorders, and those who are underweight.

Additionally, she notes that there is limited research on the safety of fasting for other groups, including people who are pregnant or lactating and individuals over the age of Jamshed points out that there are several possible time-restricted eating side effects to keep in mind, including:.

Following an early time-restricted eating schedule may offer the most benefits in terms of weight loss and metabolic health. However, it's important to pick a schedule based on what works for you and your lifestyle and what you're most likely to follow. Time-restricted eating has been shown to support weight loss in several studies.

Of course, it's best to pair time-restricted eating with a nutritious, well-rounded diet and regular physical activity to maximize your results. Time-restricted eating is a flexible eating pattern that may offer benefits in the long run, including increased weight loss and improved metabolic health.

Additionally, there are several variations available, making it easy to incorporate TRE into your schedule. However, TRE isn't a good fit for everyone and may be associated with negative side effects, some of which can be serious.

For this reason, it's best to talk to your doctor to see if TRE is worth a try and how it may impact your health. If you do decide to try TRE, these tips can make it easier to follow. Skip to Content. Shop Health Coaching Classes Editor's Picks Beauty Food Healthy Weight Login Login.
