The Influence of Time-Restricted Eating in Patients Metabolic Syndrome

2019-08-18 20:09:26 | BioPortfolio


In a randomized controlled trial, the investigators intend to measure the health impact of TRE in patients with metabolic syndrome (with three or more of the following criteria: increased waist circumference, abnormal cholesterol levels, elevated blood pressure, or elevated blood sugar), who habitually eat for more than 14 hours every day. Patients will be randomly assigned to a control group of behavioral nutrition counseling (standard of care) or the intervention group of behavioral nutrition counseling with the addition of adopting a 10 hour eating window for 12 weeks (TRE).


Circadian rhythms optimize nutrient homeostasis by orchestrating catabolic and anabolic metabolism to appropriate times of the 24 hour day. Chronic circadian rhythm disruption predisposes individuals to metabolic diseases including obesity and type 2 diabetes. Conversely, maintaining a daily rhythm of feeding and fasting cycles sustains a robust circadian rhythm which improves cellular bioenergetics and results in improved metabolism. Time-restricted eating (TRE) is a specific feeding-fasting pattern in which feeding is restricted to 8-12 hours a day.

At the beginning and end of the study (which will be three months in duration), the following parameters will be measured: height, weight, body mass index, percent body fat, waist/hip circumference and blood pressure. Blood sugar levels will be monitored continuously for 2 weeks at a time at the beginning and end of the study using a continuous glucose monitor. Additionally, a dual energy X-ray absorptiometry (DXA) scan will be used to collect information about body composition. Information will be collected about the mitochondria with a muscle biopsy. Participants will use a smartphone application (called myCircadianClock (mCC), developed by the Salk Institute) to keep track of food/beverage intake and will wear a wrist-worn actigraphy device to monitor physical activity levels and sleep.

Medical and Biotech [MESH] Definitions

The minimum acceptable patient care, based on statutes, court decisions, policies, or professional guidelines.

Organization of medical and nursing care according to the degree of illness and care requirements in the hospital. The elements are intensive care, intermediate care, self-care, long-term care, and organized home care.

Medical care provided after the regular practice schedule of the physicians. Usually it is designed to deliver 24-hour-a-day and 365-day-a-year patient care coverage for emergencies, triage, pediatric care, or hospice care.

An interval of care by a health care facility or provider for a specific medical problem or condition. It may be continuous or it may consist of a series of intervals marked by one or more brief separations from care, and can also identify the sequence of care (e.g., emergency, inpatient, outpatient), thus serving as one measure of health care provided.

Prudent standard preventive measures to be taken by professional and other health personnel in contact with persons afflicted with a communicable disease, to avoid contracting the disease by contagion or infection. Precautions are especially applicable in the diagnosis and care of AIDS patients.
