Time Limited Eating for Adolescents with Type 2 Diabetes

This study is looking at how a diet plan called Time Limited Eating (TLE) affects adolescents (ages 12-21) with type 2 diabetes. TLE means eating all your food and drinks within an 8-hour window each day and then fasting for 16 hours. Another group will eat over 12 hours or more. All participants will receive standard nutrition counseling. The study wants to see if TLE can improve blood sugar control (measured by A1c and time in range), how well the body makes insulin, and body fat/weight. To join, you need to have type 2 diabetes, an A1c below 9%, and be willing to follow the study schedule. The current recruitment status is unclear, but the study plans to enroll 100 participants.

Study design
This is a pilot randomized controlled trial, meaning participants are randomly assigned to either the Time Limited Eating group or the control group. It plans to enroll 100 participants.
What's involved
You would receive training to wear a continuous glucose monitor (CGM) for the entire 12-week study period and attend assessments at weeks 0, 4, and 12.
Compensation
Not stated in the trial record.
Follow-up
The primary outcomes are measured at Week 12 compared to baseline, indicating a 12-week follow-up period.
