Comparing 4-Week High-Intensity Interval Training and Time-Restricted Eating to Reduce Type 2 Diabetes Risk in Overweight Youth and Young Adults

What this Trial Is About

Researchers are studying the effects of two different lifestyle interventions on heart and metabolic health markers in overweight or obese adolescents and young adults aged 14 to 30 years. The study aims to compare high-intensity interval training HIIT and time-restricted eating TRE over a period of four weeks to see which approach better improves factors linked to type 2 diabetes risk and cardiovascular disease. Obesity is a major health concern linked to these conditions, making this research important for young people at increased risk. Participants are randomly assigned to one of three groups a HIIT group, a TRE group, or a control group. The HIIT group performs supervised sessions on a stationary bike three times per week, involving short bursts of intense exercise followed by rest. The TRE group restricts their calorie intake to a 10-hour daily window, choosing a consistent timing for meals, with guidance on calorie needs. The control group continues their usual lifestyle without changes. Each intervention lasts four weeks. Throughout the study, participants will have various measurements taken at the start and end of the four weeks, including weight, height, body mass index, waist and hip size, blood pressure, blood sugar, insulin, cholesterol levels, and inflammatory markers. Heart rate and exertion levels are monitored during exercise sessions. The researchers will assess changes in these biomarkers to understand how each intervention affects cardiometabolic health. The total participation time is approximately one month for each individual.
