Eating dinner at 7pm can help you live longer, study finds

In the quest for a healthier and longer life, researchers are increasingly turning their attention to the timing of our meals. Recent studies suggest that dining early, specifically having dinner at 7 PM, could hold the key to unlocking the secrets of longevity. As our understanding of circadian rhythms and their influence on various bodily functions deepens, the importance of aligning our eating habits with our internal body clocks becomes more apparent.

The human body operates on a circadian rhythm, an internal biological clock that regulates numerous physiological processes over a 24-hour cycle. This includes the sleep-wake cycle, hormone production, and metabolism. Research indicates that our organs and tissues function optimally when synchronized with these natural rhythms, and disruptions to this alignment may contribute to various health issues.

An interesting relationship between eating supper early and maybe living a longer life is explored in a study that was published in the journal Frontiers in Nutrition.

The study focuses on L’Aquila, a region in Abruzzo, Italy, which is well-known for having a large number of centenarians (those who live to be 100 years old) and nonagenarians (those who are 90 to 99 years old). The study, which looked at 68 individuals from this area, provides insight into their eating habits, especially with regard to when they eat dinner.

Eating too close to bedtime, a common modern habit, can interfere with the body’s ability to wind down and prepare for sleep. This disruption can lead to poor sleep quality, which has been linked to a higher risk of chronic conditions such as heart disease, diabetes, and obesity. By choosing to dine early at 7 PM, individuals may create a buffer between their last meal and bedtime, allowing the body to digest food more efficiently and promoting better sleep hygiene.

Remarkably, most of the centenarians and nonagenarians in L’Aquila finished their dinners early, usually at 7:13 p.m.

After more investigation, the researchers discovered a unique eating pattern: a strict calorie restriction. These individuals continued to consume little calories for a considerable amount of time—17.5 hours from supper to lunch the next day.

Moreover, the timing of our meals appears to influence our metabolism and how the body processes food. A study published in the International Journal of Obesity found that individuals who ate their main meal earlier in the day had a greater chance of weight loss compared to those who ate later. This is attributed to the body’s natural fluctuations in metabolic rate throughout the day, with it being highest in the morning and gradually tapering off towards the evening. Eating earlier may capitalize on this metabolic peak, enhancing the body’s ability to burn calories and potentially aiding in weight management.

Beyond the immediate benefits of improved sleep and metabolism, the connection between early dining and longevity is gaining attention. Some studies suggest that aligning meals with circadian rhythms could positively impact various health markers linked to longevity, such as insulin sensitivity and inflammation. Early dining may help regulate blood sugar levels more effectively, reducing the risk of insulin resistance and type 2 diabetes.

In addition to the physiological aspects, the psychological impact of an early dinner should not be overlooked. Eating earlier allows individuals to enjoy a relaxed and unhurried dining experience, promoting mindfulness and the appreciation of food. This mindful eating approach has been associated with better digestion and a reduced likelihood of overeating, further contributing to overall health and well-being.

However, it’s essential to note that the benefits of early dining extend beyond the clock; the quality and composition of the meals matter as well. A balanced diet rich in whole foods, fruits, vegetables, and lean proteins remains a cornerstone of good health. Timing alone cannot compensate for poor dietary choices.

The diets of the survey respondents were high in grains, fruits, vegetables, and legumes. On the other hand, they continued to consume very little meat, processed meat, eggs, and sugary foods.

This plant-forward strategy fits with patterns frequently linked to improved lifespan and well-being.

“Our results support the importance of a daily caloric restriction lapse, hampering nocturnal postprandial stress and optimising metabolic response, associated with high consumption of plant-based foods and physical activity for the longevity of centenarians from Abruzzo,” the researchers stated.

In conclusion, the science behind dining early at 7 PM as a means to increase longevity is compelling. Aligning our eating habits with our circadian rhythms appears to offer a range of health benefits, from improved sleep and metabolism to potential impacts on long-term health markers. Embracing the practice of early dining may not only contribute to a longer life but also enhance the overall quality of that life by fostering better sleep, metabolic health, and mindful eating habits.
