Interaction Between Early Meals (Big-Breakfast Diet), Clock Gene mRNA Expression, and Gut Microbiome to Regulate Weight Loss and Glucose Metabolism in Obesity and Type 2 Diabetes.

The circadian clock gene system plays a pivotal role in coordinating the daily rhythms of most metabolic processes. It is synchronized with the light-dark cycle and the eating-fasting schedule. Notably, the interaction between meal timing and circadian clock genes (CGs) allows for optimizing metabolic processes at specific times of the day.

Influence of Fasting until Noon (Extended Postabsorptive State) on Clock Gene mRNA Expression and Regulation of Body Weight and Glucose Metabolism.

The trend of fasting until noon (omission or delayed breakfast) is increasingly prevalent in modern society. This eating pattern triggers discordance between endogenous circadian clock rhythms and the feeding/fasting cycle and is associated with an increased incidence of obesity and T2D. Although the underlying mechanism of this association is not well understood, growing evidence suggests that fasting until noon, also known as an "extended postabsorptive state", has the potential to cause a deleterious effect on clock gene expression and to disrupt regulation of body weight, postprandial and overall glycemia, skeletal muscle protein synthesis, and appetite, and may also lead to lower energy expenditure.

Disease Progression in Older Patients With Renal Tumor Assigned to an Active Surveillance Protocol.

Background: Active surveillance (AS) is a validated option for the treatment of small renal masses (SMRs), especially in older patients. This study investigates the oncologic outcomes and competitive mortality of older patients prospectively assigned to AS.

Methods: We conducted a monocentric study on patients ≥75 years treated between 2011 and 2016 for a SMR.

Serum from type 2 diabetes patients consuming a three-meal diet resets circadian rhythms in cultured hepatocytes.

Aims: Feeding regimens alter circadian rhythms in peripheral tissues, but the mechanism is not understood. We aimed to study whether soluble factors, rather than neuronal-based communication, directly influence circadian rhythms in the liver, in response to a nutritional treatment in type 2 diabetes (T2D) patients.

Methods: Cultured hepatocytes were treated with serum of insulin-treated T2D patients following either a three-meal diet (3Mdiet) or six-meal diet (6Mdiet) and the circadian expression of clock and metabolic genes was measured.

Role of High Energy Breakfast "Big Breakfast Diet" in Clock Gene Regulation of Postprandial Hyperglycemia and Weight Loss in Type 2 Diabetes.

Postprandial hyperglycemia (PPHG) is strongly linked with the future development of cardiovascular complications in type 2 diabetes (T2D). Hence, reducing postprandial glycemic excursions is essential in T2D treatment to slow progressive deficiency of β-cell function and prevent cardiovascular complications. Most of the metabolic processes involved in PPHG, i.
