INS and prediabetes syndrome: In contrast, in a study performed by Sutton et al. [5] in which men with prediabetes were assigned to ETRE (early time-restricted eating; 6-h eating period, with dinner before 15:00) or a control schedule (12-h eating period) for 5 weeks and then crossed over to the other schedule, showed that ETRE reduced fasting insulin and insulin resistance compared with the control schedule, but did not affect fasting blood glucose levels or glucose levels recorded during a 3-h oral glucose tolerance test.
