Summary

The goal of this clinical trial is to learn if changing when and how often people eat works to improve health in adults with Type 2 diabetes. The main questions it aims to answer are:

How do these eating patterns change body weight and body fat?

Does changing meal timing and frequency lower blood sugar levels (HbA1c) over 12 weeks?

Does it lower blood fat levels, such as cholesterol and triglycerides?

Researchers will compare three groups to see which eating pattern works best:

Standard Group: Participants eat 3 main meals and 3 snacks (6 times total) each day with a calorie limit.

3-Meal Group: Participants eat only 3 main meals each day with a calorie limit.

Time-Restricted Group: Participants eat all their daily food within an 8-hour window (from 12:00 to 20:00) without a calorie limit.

Participants will:

Follow their assigned eating plan for 12 weeks.

Visit the clinic once every month for checkups and body measurements.

Give blood samples at the start and end of the study for laboratory tests.

Record the food they eat and their physical activity levels.
