Mid-day time-restricted feeding (mTRF), defined as an 8-hour eating window between 11:00 and 20:00, does not significantly improve insulin sensitivity, fasting glucose, body mass, or inflammation compared to ad libitum eating in healthy non-obese adults.

If you prefer eating later in the day (e.g., 11 AM to 7 PM), be aware that this specific mid-day TRF window may not improve insulin sensitivity, reduce body weight, or lower inflammation compared to normal eating habits in healthy, non-obese individuals. If metabolic health is your goal, shifting your eating window to end earlier (by 3 PM) may be more effective.
