Breakfast is often hailed as the most important meal of the day, but for individuals with diabetes, it’s more than just a morning ritual, it’s a crucial factor in maintaining stable blood sugar levels and overall metabolic health.
Skipping breakfast may seem harmless, but it can trigger a series of negative effects, from erratic blood sugar fluctuations to increased hunger and poor dietary choices later in the day.
For diabetics, the body’s ability to regulate glucose efficiently relies heavily on a consistent eating schedule. When breakfast is skipped, it can lead to issues such as fasting hyperglycaemia, overeating at subsequent meals, and even an increased risk of diabetic complications.
Understanding the importance of a well-balanced morning meal can make all the difference in managing diabetes effectively and avoiding potential health risks. And to understand this OnlyMyHealth team interacted with Reshma Nakte, Clinical Nutritionist, Weight loss expert, Lactation Expert (BPNI), M.Sc. Applied Nutrition, ICMR-NIN.
1. Effects on Blood Sugar Levels
Skipping breakfast disrupts blood sugar regulation in several ways:
Fasting Hyperglycaemia: “The ‘dawn phenomenon,’ where hormones like glucagon and cortisol raise blood sugar levels in the morning, can cause blood sugar to rise further if breakfast is skipped,” explains Nakte. The absence of carbohydrate intake deprives the body of the nutrients required to stabilise blood sugar.
Post-Lunch Hyperglycaemia: Missing breakfast also impairs the body’s ability to manage blood sugar after subsequent meals. “This is known as the impaired second-meal response, where skipping breakfast may lead to a higher blood sugar spike after lunch,” says Nakte.
Ketone Formation: Prolonged fasting forces the body to break down fat for energy, leading to increased ketones. “For those with Type 1 diabetes, this could elevate the risk of diabetic ketoacidosis (DKA), a potentially life-threatening condition,” she adds.
2. Metabolic Consequences
Skipping breakfast can also lead to dangerous metabolic shifts:
Risk of Hypoglycaemia: “When diabetes medications such as insulin or sulfonylureas are taken without food, there’s an enhanced risk of blood sugar dropping to dangerously low levels,” warns Nakte.
Modified Fat Metabolism: Extended fasting prompts the body to rely on fat breakdown, increasing levels of free fatty acids and ketones in the bloodstream. While this process provides energy, it also raises the risk of metabolic disturbances like DKA.
3. Overeating and Hunger
One of the most immediate effects of skipping breakfast is excessive hunger later in the day. This can lead to overeating at subsequent meals, disrupting glycaemic control. “Missing breakfast can cause a cycle of overeating, particularly at lunch or dinner, which exacerbates blood sugar fluctuations,” Nakte notes.
Additionally, skipping breakfast may result in cravings for unhealthy, high-calorie foods, further derailing dietary goals for those with diabetes.
4. Hormonal Dysregulation
Breakfast plays a vital role in regulating hunger hormones such as ghrelin and leptin. When skipped, the balance of these hormones is disrupted. According to Nakte, “This hormonal dysregulation can lead to poor eating habits and cravings for calorie-dense, nutrient-poor foods.”

Recommendations for Diabetics
The key to effective diabetes management lies in consistent and balanced eating habits. Reshma Nakte provides these practical recommendations:
Balanced Breakfast: A morning meal rich in fibre, protein, and healthy fats helps stabilise blood sugar levels throughout the day. Examples include whole-grain toast with avocado, Greek yoghurt with nuts, or a vegetable omelette paired with a slice of multigrain bread.
Proper Meal Timing: “Eating at regular intervals is essential for avoiding metabolic imbalances and ensuring steady blood sugar levels,” Nakte advises.
Conclusion
For people with diabetes, skipping breakfast is far more than just an inconvenience-it can trigger a cascade of negative effects on blood sugar regulation, metabolism, and hunger hormones. While occasional lapses might not seem significant, chronic breakfast-skipping poses serious health risks, including fasting hyperglycaemia, hypoglycaemia, and the potential for diabetic ketoacidosis in Type 1 diabetes patients.
Nakte concluded, “Promoting regular meals is the cornerstone of diabetes management. A balanced breakfast sets the stage for stable blood sugar levels, better energy, and improved overall well-being.” Making breakfast a daily priority is a small but impactful step towards maintaining long-term health for individuals with diabetes.
