The exact time you should eat dinner

We know that what we eat can influence our health and longevity—but research now suggests that when we eat may be just as important. And according to scientists, there’s a surprisingly precise time to sit down for dinner if you want to give yourself the best shot at a longer, healthier life.

Why meal timing matters

Healthy eating isn’t just about choosing the right foods; the timing of your meals can also impact your metabolism, digestion, and long-term wellbeing. Studies have shown that eating too late in the evening can interfere with sleep, raise blood sugar levels, and even contribute to weight gain.

Now, new findings indicate that eating dinner earlier—well before bedtime—might also play a role in extending life expectancy.

The “magic” time: 7:13 pm

A study published in Frontiers in Nutrition examined the eating habits of residents in L’Aquila, a town in Italy famous for its unusually high number of people living into their 90s and beyond. Researchers found a consistent pattern: most residents sat down to dinner at around 7:13 pm.

The scientists believe this habit, along with other lifestyle factors, could be one of the secrets to the community’s impressive longevity.

More than just an early dinner

Of course, these Italian long-livers don’t rely solely on early dining to stay healthy. Their overall lifestyle is a blend of nutrient-rich foods, moderate calorie intake, and regular physical activity. The combination supports heart health, reduces inflammation, and keeps the body functioning efficiently well into old age.

Why earlier might be better

Eating dinner earlier gives your body more time to digest before sleep, which can improve metabolic health and reduce the risk of chronic diseases linked to late-night eating, such as type 2 diabetes. It may also help regulate hormones like insulin and cortisol, both of which play a role in weight management and ageing.

The takeaway

While you don’t need to be exact to the minute, aiming to finish dinner around 7 pm could be a smart, science-backed habit to adopt—especially when paired with a balanced diet and active lifestyle. It’s a small shift that, over time, might just help you live not only longer, but better.
