What this trial studies

This randomized trial evaluates the health benefits of intermittent dietary restrictions, including low-carbohydrate and calorie restriction diets, in school-aged children with cardiometabolic risk factors. Participants will be assigned to either an intermittent low-carbohydrate diet, an intermittent calorie restriction diet, or a general health education program over a 12-month period. The study aims to determine the effectiveness of these dietary approaches in improving cardiometabolic health compared to standard dietary guidelines. The intervention phase lasts for three months, followed by a nine-month self-maintenance phase.

Who should consider this trial

Good fit: Ideal candidates are children aged 7-18 years with at least one cardiometabolic abnormality such as prediabetes, lipid abnormalities, or elevated blood pressure.

Not a fit: Patients with severe health conditions like heart failure, liver or kidney disease, or those who have undergone bariatric surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide effective dietary strategies to reduce cardiometabolic risks in children, potentially improving their long-term health outcomes.

How similar studies have performed: While intermittent dietary restrictions have shown effectiveness in adults, evidence in pediatric populations is limited, making this approach relatively novel.
