Health experts warn against the risks of late breakfasts
Nutrition experts from the Cleveland Clinic suggest that delaying breakfast can negatively impact overall health by disrupting the body's biological clock. Biologically, a late breakfast is defined as eating more than two hours after waking up or fasting past 9:00 AM for those on a standard schedule.
To optimize metabolism, digestive enzymes, and hormone activity, experts recommend eating breakfast within one to two hours of waking, ideally between 6:30 AM and 8:00 AM. Consuming breakfast during this window helps replenish glycogen levels, regulate insulin, and provide necessary fuel for brain function. Delaying meals can lead to prolonged energy deficits and metabolic disruption.
