Metabolic syndrome is a group of risk factors including 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, especially in the state of Jalisco. Research shows that not only what we eat but also when we eat can impact health. This study is testing whether combining time-restricted eating (TRE), which limits food intake to a specific daily time window, with a psychochrononutritional program that includes psychological, chronobiological, and nutritional support can improve adherence and health outcomes more than just following a time-restricted eating schedule alone. The study will last eight weeks and involve 64 adults aged 18 to 60 with metabolic syndrome from Ciudad Guzmán, Jalisco. Participants will be randomly assigned to one of two groups: one group will receive psychochrononutritional support through eight weekly sessions covering topics like healthy eating, portion control, sleep, and physical activity, while the other group will receive only instructions on their eating window. Each group will be further divided to follow either an 8-hour or a 10-hour eating window during which they can consume food and caloric drinks; outside this window, only water or non-caloric beverages are allowed. Participants will have measurements taken before and after the intervention, including waist circumference, blood pressure, glucose levels, cholesterol, and triglycerides. They will also complete questionnaires about diet quality, chrononutrition, treatment adherence, and sleep quality. Researchers will monitor treatment adherence throughout the eight weeks. The goal is to observe improvements in metabolic health markers and better adherence to the eating schedule, especially in the group receiving psychochrononutritional support.
