Metabolic syndrome is a group of risk factors like abdominal obesity, high blood pressure, high triglycerides, and insulin resistance that increase the chance of developing type 2 diabetes and heart disease. This condition is becoming more common in Mexico. Researchers are exploring how the timing of eating, not just what is eaten, affects health. This study compares the effects of time-restricted eating TRE alone versus TRE combined with a psychochrononutritional program, which includes psychological, biological, and nutritional support, to see if the combination improves adherence and health outcomes better than TRE alone. The study will recruit 64 adults aged 18 to 60 with metabolic syndrome in Ciudad Guzmn, Jalisco, Mexico. Participants will follow an eight-week TRE plan restricting eating to either an 8-hour or 10-hour daily window. They will be randomly assigned to either receive psychochrononutritional support through weekly group sessions or only instructions about the eating window. The psychochrononutritional program covers topics like body clocks, healthy eating, portion control, sugary drinks, sleep impacts, social factors, physical activity, and informed decisions. Participants will be assessed before and after the intervention on measurements including waist circumference, blood pressure, blood sugar, cholesterol, triglycerides, body weight, body composition, visceral fat, diet quality, and sleep quality. Adherence to the eating schedule will be monitored during the eight weeks. The study aims to see if the combined approach leads to better health improvements and adherence than TRE alone. Participants may be followed up to measure lasting effects after the intervention ends.
