Scientists have linked meal timing to weight regulation and metabolic health.

Problems with obesity and related metabolic disorders such as type 2 diabetes and cardiovascular diseases are becoming important health challenges. Scientific studies show that not all calories have the same effect on metabolism. Individual differences in hormonal responses and genetic factors can also affect how calories are processed and stored in the body. This was reported by the MDPI portal.

Chrono-nutrition, which focuses on the timing of meals and its relationship to the circadian rhythms of the body, has become a significant area of research in the context of maintaining metabolic health and energy balance. Dysfunction of circadian rhythms, for example, irregular meals or night shifts, is associated with a deterioration in metabolic parameters, which leads to obesity and type 2 diabetes.

Some studies show that eating during the active phase of the day (usually in the morning) corresponds to the peak time of insulin sensitivity and glucose tolerance, while late dinners can lead to a deterioration in metabolism and increased fat accumulation. This discovery highlights the possibility of using chrono-nutrition as an additional approach to traditional weight loss and nutrition correction strategies.

Circadian rhythms are internal biological cycles that control body functions such as metabolism, hormone secretion, sleep, and wakefulness. They are regulated by a complex network of biological clocks that synchronize internal processes with external signals, primarily the cycle of light and dark. Violations of these rhythms, such as irregular meals or job changes, can disrupt metabolism and increase the risk of type 2 diabetes.

Research shows that a mismatch between circadian rhythms and mealtimes (such as eating at night) disrupts this balance and contributes to hyperphagia and weight gain. These disorders are especially pronounced in people who work night shifts. They have disrupted circadian rhythms and, as a result, an increased risk of obesity and metabolic disorders.

According to numerous studies, eating early and limiting meals to late in the evening are associated with improved metabolic health, reduced insulin resistance, and improved lipid profile. Systematic observations also show that skipping breakfast is associated with an increased risk of obesity and type 2 diabetes. These findings confirm the importance of time constraints on food intake and maintaining regular circadian rhythms for the prevention and treatment of metabolic diseases.

Understanding the relationship between meal timing and circadian rhythms opens up new perspectives in the treatment of obesity, type 2 diabetes, and other metabolic disorders. Optimizing meal timing can be an effective tool in treatment, along with other strategies such as physical activity and a balanced diet.

Earlier, on November 19, Medical Xpress magazine reported on the need to adjust the dinner time in winter. According to the publication, early dinners can be more consistent with the body's natural metabolic rhythms, especially when the last meal occurs long before the start of the body's "rest" phase.
