One of the main reasons why skipping breakfast causes belly fat accumulation and affects blood sugar is because breakfast helps to activate metabolism after a long night without eating. When you skip breakfast, your body will be in a "fasting" state for longer, causing energy metabolism to slow down.
Skipping breakfast can reduce insulin levels in the blood, thereby increasing appetite at noon and evening, easily leading to consuming too many calories, causing the body to store energy as excess fat.
Studies have also shown that eating breakfast helps control blood sugar levels. A study published in the American Journal of Clinical Nutrition found that people who eat breakfast have more stable blood sugar levels than those who skip breakfast. Unstable blood sugar levels make it easier for the body to convert energy into excess fat, especially in the abdominal area.
Skipping breakfast also changes your eating habits throughout the day, making it easier to eat more processed foods that are high in sugar and unhealthy fats. According to research by the World Health Organization, overconsumption of processed foods is a major contributor to the rise in global obesity rates.
Furthermore, skipping breakfast also affects physical activity. People who skip breakfast often feel tired and lack the energy to participate in physical activities, making it more difficult to burn calories. People who eat breakfast regularly are more likely to maintain a stable weight and have a lower risk of obesity than those who skip breakfast.
