Time Restricted Eating in Patients With Microalbuminuria

Официальное название

Impact of Time-Restricted Eating (TRE) on Kidney Health (The TREK Study)

Обзор

This is a clinical trial to assess how time-restricted eating (TRE) may improve kidney health and filtration patients with type 2 diabetes and increased protein content in their urine. All participants will be participating in TRE in which they follow a consistent 8-10 hour eating window everyday.

Подробное описание

The proposed study aims to address the unmet medical need of treating microalbuminuria, particularly in patients with diabetes, through a prospective single-arm intervention lasting twelve weeks. Microalbuminuria, indicative of abnormal glomerular capillary permeability, serves as an early marker for renal impairment and heightened cardiovascular risk. The study hypothesizes that adherence to time-restricted eating (TRE) over the intervention period will significantly reduce microalbuminuria levels, as assessed by the urine albumin-to-creatinine ratio (uACR). Unlike other methods, uACR provides an estimation of 24-hour urine albumin excretion and is unaffected by variations in urine concentration, eliminating the need for timed specimens or 24-hour collections. If successful, this study could highlight the potential of TRE as a non-invasive and accessible dietary intervention for managing microalbuminuria and related conditions.
