According to a 2023 study by Northwestern University and the University of Illinois (USA), people who eat breakfast before 8:30 a.m. often have lower blood sugar and less insulin resistance than those who eat breakfast later.
After a night of fasting, the body's metabolism slows down. Therefore, eating breakfast within two hours of waking up helps stimulate the metabolism.
After waking up, blood sugar levels tend to rise due to the release of hormones such as cortisol and growth hormone. Skipping breakfast or eating too late, such as your first meal at noon, can lead to hypoglycemia with symptoms such as dizziness, fatigue and difficulty concentrating.

For people with diabetes, hypoglycemia can occur due to too much insulin in the blood, so they should not fast for long periods of time. Therefore, the general rule is to maintain three main meals and two snacks per day to avoid hypoglycemia. Each main meal should be spaced 5-6 hours apart, especially for people with diabetes.
Eating breakfast on time not only helps control blood sugar but also benefits your overall health. Eating breakfast regularly helps provide energy for the body and can reduce the risk of chronic diseases.
