Description

Summary

It is a 12-week study. The participants will follow three different diets, and during each diet period, and the participants will wear our device, and blood samples will be collected.

Details

The investigators will conduct a randomized, controlled crossover intervention study. The investigators will enroll 54 participants, aged >18 years, BMI >25 kg/m2 with metabolic syndrome. During the first phase, all participants will consume their habitual diet for 2 weeks to establish baseline. Then participants will be randomized to either a Mediterranean diet (MED), high-fat/low carb diet (HF/LC), or low-fat diet (LF) for 14 days with 2 weeks washout between the different diets. The wearable system will monitor basal levels and the changes for glucose, cholesterol, TG, and NO through sweat analysis and HR, HRV, and PWV for carotid arterial stiffness during each diet intervention.
