Summary

This trial will test if time-restricted eating can help people with obesity and prediabetes manage their weight and improve their insulin sensitivity.

Who is the study for?
This trial is for adults aged 18-70 with obesity (BMI of 30-50) who are sedentary or lightly active. It's not suitable for those unstable in weight, on certain medications, unable to maintain a food/activity log, with eating disorders, irregular menstrual cycles, smokers, diabetics, night shift workers, or pregnant individuals.
What is being tested?
The study tests if eating within an 8-hour window (12pm-8pm) leads to better weight management compared to daily calorie restriction or no intervention over a year. Participants will first focus on losing weight for six months and then maintaining it for another six.
What are the potential side effects?
Potential side effects may include hunger during fasting periods, possible changes in energy levels and mood swings due to altered meal timing and reduced calorie intake.
