Meal skipping and its impact on blood sugar levels

Research indicates that while occasional meal skipping may not significantly impact blood sugar, regular patterns—particularly skipping breakfast—can disrupt glucose regulation. A 2019 study involving healthy young men found that those who skipped breakfast experienced significantly higher blood sugar levels after lunch compared to days when they ate breakfast.

Furthermore, a 2020 study linked breakfast skipping to poorer glucose control in individuals with type 2 diabetes. Frequent disruptions in blood sugar levels are associated with an increased risk of prediabetes and type 2 diabetes. While structured intermittent fasting, such as early time-restricted feeding, may improve glucose control for some, other studies have found no advantage over standard diets.

To maintain stable glucose levels, experts recommend a consistent eating schedule. Consuming breakfasts rich in protein and fiber, and pairing carbohydrates with protein and fiber, can slow digestion and stabilize sugar levels. It is also suggested that consuming all daily meals within a 12-hour window and avoiding eating immediately before sleep may be beneficial. Individuals with blood sugar regulation issues should consult a physician before attempting intermittent fasting.
