Brief Summary

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

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.

Detailed Description

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

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.

Study Groups

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

Time Restricted Eating (TRE) Group

Participants will limit the number of hours they eat in a dat to an 8-10 window and will also receive the standard heath and nutritional wellness guidelines. They will also be required to log food entries through the use of a smartphone app. Patients will also be required to wear a continuous glucose monitor (CGM) for the first and last two weeks of the 14 trial.

Group Type EXPERIMENTAL

Time Restricted Eating

Intervention Type BEHAVIORAL

Participants in the TRE group with continue to follow their physicians treatment plan for type II diabetes mellitus and consume all of their food within an 8-10 hour eating window.
