Time-restricted eating (TRE) improves glucose homeostasis, lipid metabolism, and blood pressure in individuals with metabolic conditions, independent of weight loss.

If you have metabolic risks like prediabetes or high blood pressure, try limiting your daily eating window to 8-10 hours, preferably starting earlier in the day (e.g., 8am-4pm). This timing aligns with your body's natural rhythms and can improve insulin sensitivity and blood pressure, even if your weight doesn't change. Ensure you are eating enough protein within that window to protect muscle mass, especially if you are older.

GoodSupportsHIGH confidence
a growing body of evidence suggests that TRE can improve glucose and lipid metabolism and blood pressure and can contribute to improved overall health, including reduced risk of cardiovascular disease... a proof-of-concept study recently demonstrated that, in men with prediabetes, 5 weeks of early TRE... increased insulin sensitivity and β-cell responsiveness, whilst lowering blood pressure and oxidative stress, independent of weight-loss

Why this rating

Based on a review of multiple human studies, including RCTs and proof-of-concept trials, though the paper notes gaps in long-term data.
