Time-restricted eating (TRE) may not improve cardiometabolic health if you don't change what or how much you eat. Women with obesity who practiced early TRE (eating from 8 AM to 4 PM) or late TRE (1 to 9 PM) but kept their calorie intake and physical activity levels the same experienced no changes in their insulin sensitivity, blood glucose, blood lipids, inflammation, oxidative stress, or body composition makers. The late TRE group did see a later shift in their circadian phase (~24 minutes) compared to the early TRE group. Circadian-timed eating is important, but without an emphasis on dietary quality, metabolic improvements seem to be modest.
