Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Diet 1 (one of the three kinds of diets)

participants will be randomized to diet 1 for 2 weeks. A continuous glucose monitor (CGM) will be placed and the integrated sweat sensor and vascular sensor will be administered.

Group Type ACTIVE_COMPARATOR

Mediterranean diet (MED), high-fat/low carb diet (HF/LC), and low-fat diet (LF)

Intervention Type DIETARY_SUPPLEMENT

Participants will be randomized to either Mediterranean diet (MED), high-fat/low carb diet (HF/LC), or low-fat diet (LF).

The integrated sweat sensor and vascular sensor (wearable)

Intervention Type DEVICE

The integrated sweat sensor and vascular sensor will be worn of each diet period.

continuous glucose monitor (CGM)

Intervention Type DEVICE

A continuous glucose monitor (CGM) will be placed on the patients during each diet period.

Diet 2 (one of the two remaining kinds of diets, excluding Diet 1)

participants will be randomized to diet 2 for 2 weeks. A continuous glucose monitor (CGM) will be placed and the integrated sweat sensor and vascular sensor will be administered.

Group Type ACTIVE_COMPARATOR

Mediterranean diet (MED), high-fat/low carb diet (HF/LC), and low-fat diet (LF)
