Time-restricted eating (TRE) significantly reduces body weight and fasting insulin levels in overweight and obese women compared to control groups, without negatively affecting fat-free or lean body mass.

If you are overweight or obese, try restricting your eating window to 8-10 hours a day (e.g., 10 AM to 6 PM). This approach has been shown to help women lose weight and improve insulin sensitivity without losing muscle mass, and it is often easier to stick to than strict calorie counting.

TRE significantly reduced body weight (WMD = −1.927 kg, 95% CI: −3.688 to −0.166, p = 0.032) and fasting insulin levels (WMD = −2.120 μU/mL, 95% CI: −4.172 to −0.069, p = 0.043)... No lean mass loss was observed.
