Time Restricted Eating in Patients With Microalbuminuria

Recruiting now · Phase 1

Conditions studied: Type 2 Diabetes Mellitus (T2DM), Time Restricted Eating, Microalbuminuria

In brief

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.
