Time-restricted feeding (TRF) improves insulin sensitivity and glycemic control (including reduced glucose variability and HbA1c) in individuals with overweight or obesity, independent of significant weight loss in some studies.

If you have insulin resistance or pre-diabetes, try shifting your eating window to end earlier in the evening (e.g., 8 PM) and start later in the morning (e.g., 4 PM). This timing aligns with your body's natural circadian rhythms, helping to lower blood sugar spikes and improve how your body uses insulin, even if the scale doesn't move dramatically.
