We’ve all heard that eating later in the day is bad for our waistlines, but why is that? A new study addressed this question by comparing people who ate the same foods at different times of the day.
When everything else is constant, does the time we eat matter? “First author Nina Vujovi, a researcher at Boston’s Brigham and Women’s Hospital who studies sleep and circadian disorders, made this statement.
According to a study published on Tuesday in the journal Cell Metabolism, the answer is yes — eating later in the day doubles the likelihood that you’ll feel more hungry.
We discovered that eating four hours later significantly affects our hunger levels, how many calories we burn after eating, and how much fat we store. “Together, these changes may explain why eating after a certain time is linked to an increased risk of obesity, as observed by other studies, and offer novel molecular insight into the underlying mechanisms,” the authors write.
According to researchers, the study lends credence to the idea that circadian rhythm, which affects important physiological processes like body temperature and heart rate, affects how our systems absorb fuel.
The research did demonstrate that eating later causes “an increase in appetite, effects hormones and also changes gene expression, notably in terms of fat metabolism with a tendency towards less fat breakdown and greater fat deposition,” according to the study.
Although earlier research have connected eating later to weight gain, this study did not evaluate weight loss and hence cannot demonstrate a direct relationship, according to Kolla, a non-participant in the study. Additionally, he added, studies have connected skipping breakfast to obesity.
“So, rather than having dinner late, could skipping breakfast have caused these results?
The review was little – just 16 overweight or fat individuals – yet painstakingly intended to dispense with other possible reasons for weight gain, the creators said.
Late-night eating has been linked to obesity in previous studies, but this might be the most controlled examination of its kind. The study controlled for the amount, type and timing of meals, physical activity, sleep, room temperature and light exposure. All participants were healthy, without any history of diabetes or shift work, which can affect circadian rhythm. Every person in the study ate three meals per day, with one either at breakfast time, lunchtime or dinnertime.
The results showed that those who ate their last meal later in the day had a higher body mass index (BMI) than those who ate their last meal earlier. They also had poorer quality sleep and were
All members were healthy, without any set of experiences of diabetes or shift work, which can influence circadian beat, and had standard actual work. Every individual in the review was kept to a severe sound rest/wake plan for around three weeks and was furnished with arranged dinners at fixed times for three days before the lab exploration started.

Members were then randomized into two gatherings. One gathering ate calorie-controlled feasts at 8 a.m., early afternoon, and 4 p.m., while the other ate similar dinners four hours after the fact, around early afternoon, 4 p.m. what’s more, 8 p.m. for the six days announced in the review. Proportions of craving and hunger were accumulated multiple times each while tests for muscle versus fat, temperature, and energy consumption were assembled on three separate days.
Results showed that food cravings multiplied for those on a night-eating system. Individuals who ate later in the day and pungent food sources, meat and, less significantly, a longing for dairy food sources and vegetables.
By taking a gander at the consequences of blood tests, scientists had the option to see the reason why: Levels of leptin, a chemical which lets us know when we feel full, were diminished for late eaters versus early eaters. In correlation, levels of the chemical ghrelin, which spikes our craving, rose.
“What’s going on is that our outcomes show that late eating causes an expansion in the proportion of ghrelin and leptin found the middle value of across the full 24-hour rest/wake cycle,” Scheer said. As a matter of fact, the investigation discovered that the proportion of ghrelin to leptin rose by 34% when dinners were eaten later in the day.
These progressions in craving controlling chemicals fits well with the expansion in yearning and hunger with late eating,” Scheer said.
At the point when members ate later in the day they likewise consumed calories at a more slow rate than when they ate at before times. Trial of their muscle versus fat found changes in qualities that would affect how fat is scorched or put away, the review found.
“These progressions in quality articulation would uphold the development of fat tissue by arrangement of additional fat cells, as well as by expanded fat capacity,” Scheer said.
It’s not known if these impacts could go on after some time, or on individuals who at present take prescriptions for persistent sickness, which were avoided from this review. Further review is required, the creators said.
