Eating within 6-8 hrs improves insulin sensitivity
Eating early in the day aligns with circadian rhythms and improves insulin sensitivity, β cell responsiveness, blood pressure, oxidative stress, and appetite.
In the study, eight men with prediabetes tried following eTRF and eating at typical American meal times for five weeks each. On the eTRF schedule, the men each started breakfast between 6:30-8:30 each morning, finished eating six hours later, and then fasted for the rest of the day—about 18 hours. Everyone finished dinner no later than 3 p.m.

Early time-restricted feeding improved insulin sensitivity, which reflects how quickly cells can take up blood sugar, and it also improved their pancreases’ ability to respond to rising blood sugar levels. The researchers also found that eTRF dramatically lowered the men’s blood pressure, as well as their oxidative stress levels and their appetite levels in the evening.
