Effect of Post Dinner Snack and Pre-Breakfast Consumption on Sleep Quality, Heart Rate Variability, Temperature, Interleukin-6, and Cortisol Levels in Healthy Males

What this Trial Is About

Researchers are studying how eating snacks after dinner and before breakfast affects sleep quality, heart rate variability (HRV), body temperature, and stress-related hormones like cortisol and interleukin-6 (IL-6) in healthy men aged 30 to 50. The study explores the body's natural 24-hour rhythm and how diet influences important health factors, including heart and mental health. This research aims to better understand how these snacks might impact the body's physiological processes and overall well-being. Participants are divided into groups receiving different combinations of snacks: some consume a post-dinner snack of nuts (including peanuts, walnuts, cashews, almonds, and pistachios) and various pre-breakfast snacks such as peanuts or raisins, while others receive no snacks. The study uses a randomized design with single masking, comparing these groups over an intervention period. Two assessments occur: one before and one after the intervention, with statistical analysis to compare the effects. During the study, participants will have their heart rate variability, sleep quality, cortisol and IL-6 levels, and body temperature measured at the start and after three weeks. Additional tests include blood pressure, heart rate, lipid profiles, liver and kidney function, inflammation markers, and stress scales. These evaluations help researchers monitor the participants' physiological responses and understand the impact of the dietary interventions on circadian rhythm and stress markers.
