About

Metabolic syndrome (MetS) is a global health issue defined by a cluster of risk factors-abdominal obesity, elevated blood pressure, high fasting blood sugar, high triglycerides, and low HDL cholesterol-that together significantly increase the risk of cardiovascular disease, type 2 diabetes, and overall mortality. Globally, about 20-25% of adults are affected, but prevalence varies by region and population; in Saudi Arabia, studies report rates ranging from 28.3% to 56.4%, with higher rates observed in northern and central regions and among men. Major contributors to MetS in Saudi Arabia include obesity, sedentary lifestyle, smoking, and poor dietary habits, such as low fruit consumption. Effective management strategies focus on weight loss through caloric restriction, intermittent fasting, and increased physical activity, all of which have demonstrated improvements in metabolic markers like insulin sensitivity, blood pressure, and lipid profiles. Despite international evidence supporting these interventions, no randomized controlled trials have yet evaluated the combined effects of these approaches on MetS biomarkers in Saudi adults, underscoring the need for targeted research and public health initiatives to address the high and regionally variable burden of MetS in the country.

Full description

This study aims to evaluate the effectiveness of interventions involving intermittent fasting, physical activity, and caloric restriction on metabolic syndrome biomarkers, body composition and lifestyle characteristics among patients with metabolic syndrome in Riyadh, Saudi Arabia. A randomized controlled trial (RCT) will be conducted at two hospitals, with 140 participants randomly assigned to two groups: Intervention Group the participants will be engaged in Intervention program of modified IF (Intermittent fasting, caloric restriction and physical activity) and Control Group: the participants will be engaged standard intervention provided by hospital. The primary outcomes will include changes in glycemic control (fasting blood glucose, HbA1c), cardiovascular risk markers (blood pressure, lipid profile), anthropometric measures (weight, BMI, waist circumference), physical activity levels, sleep quality, and dietary intake, assessed before and after the intervention to determine the comparative effectiveness of each approach on MetS biomarkers.
