Summary
This trial will test whether eating earlier in the day and/or light therapy can improve blood sugar and other aspects of health in people with type 2 diabetes.
Who is the study for?
Adults aged 30-80 with type 2 diabetes, HbA1c levels between 7.0 - 10.0%, and waking up between 5-9 am can join this trial if they're on stable diabetes medication or none at all. Excluded are those with severe health issues like unstable heart or liver disease, major psychiatric conditions, outdoor activity over 1.5 hours/day, recent significant weight changes, or travel plans that disrupt time zones during the study.
What is being tested?
The study is examining if eating earlier in the day combined with timed light therapy can better manage blood sugar in type 2 diabetics compared to no change in meal timing or light exposure. It will also assess effects on sleep, weight, body composition, cardiovascular health, quality of life and mood.
What are the potential side effects?
While not explicitly stated for this trial's interventions (Early Time-Restricted Feeding and Timed Light Therapy), potential side effects may include discomfort from changing eating habits and possible eye strain or sleep disturbances from light therapy.
