Vliv časově omezeného stravování na metabolickou a neuroendokrinní homeostázu, zánět a oxidační stres u pacientů s metabolickým syndromem: Pilotní klinická studie TREMNIOS

The main purpose of the clinical trial is to determine the health impact of a dietary intervention known as time-restricted eating (TRE) in patients with metabolic syndrome (defined as the presence of elevated fasting plasma glucose and two or more of the following criteria: increased waist circumference, elevated fasting plasma triglycerides, reduced high-density lipoprotein-cholesterol, elevated blood pressure) and self-reported dietary intake of ≥14 hours per day. Participants will reduce the amount of time they eat to 10 hours per day over a 12-week monitored intervention followed by a 12-week self-directed intervention and will log their dietary intake using a smartphone application (myCircadianClock (mCC) app). Glucose homeostasis (blood glucose levels will be monitored continuously for 2 weeks at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention using a continuous glucose monitor), and other metabolic, neuroendocrine, inflammatory and oxidative stress/antioxidant defense biomarkers, body weight and composition, blood pressure, heart rate, sleep and activity (using mCC app), personal sense of wellness and dietary timing (using health questionnaires) will be evaluated at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention.

Detailní popis

Metabolic syndrome occurs in approximately 30% of adults and is associated with increased risk of cardiovascular disease and type 2 diabetes. Circadian rhythm disruption due to lifestyle including erratic eating patterns may lead to metabolic and neuroendocrine dysfunction, inflammation, oxidative stress, and cardiometabolic diseases. Maintaining a daily rhythm of eating and fasting cycles sustains a robust circadian rhythm which improves cellular bioenergetics and metabolism. Recent studies support the notion that restricting a period of food intake to 8-12 hours a day (time-restricted eating, TRE) can prevent and reverse obesity and metabolic dysfunction.

The main purpose of the clinical trial is to determine the health impact of TRE in patients with metabolic syndrome (defined as the presence of elevated fasting plasma glucose and two or more of the following criteria: increased waist circumference, elevated fasting plasma triglycerides, reduced high-density lipoprotein-cholesterol, elevated blood pressure) and self-reported dietary intake of ≥14 hours per day. Participants will reduce the amount of time they eat to 10 hours per day over a 12-week monitored intervention followed by a 12-week self-directed intervention and will log their dietary intake using a smartphone application (myCircadianClock (mCC) app, developed by the Salk Institute for Biological Studies). The participants will select a 10-h eating window that best suits their lifestyle. All food/beverages except water must be consumed within the time-interval. No further dietary restrictions will be applied. The participants will be provided with behavioral nutritional counseling by a dietician. Glucose homeostasis (blood glucose levels will be monitored continuously for 2 weeks at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention using a continuous glucose monitor), and other metabolic, neuroendocrine, inflammatory and oxidative stress/antioxidant defense biomarkers, body weight and composition, blood pressure, heart rate, sleep and activity (using mCC app), personal sense of wellness and dietary timing (using health questionnaires) will be evaluated at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention. The investigators will assess for compliance with TRE using mCC app.
