Hello! Have you been experiencing frequent fatigue lately, feeling sleepy after meals, or sometimes even overeating? Even if you don't have diabetes, if you experience these symptoms, it might be worth checking your blood sugar levels. Experts emphasize that consistent blood sugar management is crucial for maintaining our overall health and vitality.

Why is Blood Sugar Important? Do I Need to Manage It Even Without Diabetes?

Blood sugar management isn't just for people with diabetes. By checking blood sugar levels with a continuous glucose monitor, you can reduce everyday issues like fatigue, overeating, and low mood that you might not have even noticed, and it greatly helps maintain a consistent energy rhythm throughout the day.

A group that particularly needs attention is those in the prediabetes stage. This stage, estimated to affect about 14 million people in Korea alone, is easy to overlook due to a lack of distinct symptoms. However, without proper management, there's a high probability it can progress to diabetes, making early management extremely important.

Blood sugar levels are significantly influenced not only by the food we eat but also by lifestyle factors such as chronic stress and lack of sleep. Even without diabetes, consciously observing your blood sugar changes can help you understand how your body reacts, and further, it can be a great aid in developing healthy lifestyle habits for yourself.

6 Lifestyle Habits for Blood Sugar Stabilization Recommended by Harvard Medical School

So, what are the specific ways to maintain stable blood sugar levels without spikes in daily life? Based on verified information from sources like ≪Harvard Health Publishing≫ by Harvard Medical School, here are some proven methods.

• Maintain Consistent Meal Times: Eating at regular intervals is effective in preventing blood sugar fluctuations. For example, if you fast for more than 5 hours during the day and then suddenly eat a large amount in the evening, the likelihood of a 'blood sugar spike' — a rapid rise in blood sugar — increases.
• Practice Eating Smaller, More Frequent Meals: Instead of eating excessively large portions at once, it's better to divide your meals into smaller, more frequent portions to prevent rapid blood sugar fluctuations. This is one of the most recommended methods, alongside consistent meal times.
• Try a Mediterranean Diet: A Mediterranean diet, which includes fruits, vegetables, legumes, whole grains, nuts, seafood, and skinless chicken, is excellent for maintaining satiety and reducing blood sugar spikes. On the other hand, ultra-processed foods can cause blood sugar to surge rapidly, so caution is advised.
• Exercise Consistently and Regularly: Moderate exercise for at least 30 minutes a day, 5 or more days a week, is recommended. Exercise helps our bodies use insulin more efficiently. Like meals, it's important to maintain consistent intervals for exercise.
• Keep a Food Journal: Develop the habit of recording what you eat and when, using a notebook or an app. Experts say that by actively recording, you might be surprised by how often and how much you actually eat. This can be a great help in objectively understanding and improving your eating habits.
• Quit Smoking: Smoking increases insulin resistance, making blood sugar control difficult. Furthermore, it's linked to unhealthy eating habits and can negatively impact blood sugar management, so quitting smoking is essential.
