简要总结
The investigators intend to measure the health impact of a dietary intervention known as time restricted feeding (TRF) on patients with metabolic syndrome (three or more of: increased waist circumference, abnormal cholesterol levels, elevated blood pressure, or elevated blood sugar). The investigators will enroll patients with metabolic syndrome who eat for ≥ 14 hours per day and will ask participants to reduce daily oral intake to 10 hours per day. The investigators will assess the impact of this dietary change using measures obtained before and after a 12 week intervention period, including body mass index, blood pressure, various lab parameters and blood sugar levels (assessed using a continuous glucose monitor). The investigators will assess for compliance with TRF using a Smart Phone application (myCircadianClock (mCC) app).
