Body reduces insulin sensitivity in the evening
After eating, glucose enters the blood and needs insulin to be delivered to cells. However, in the late afternoon, cells become less sensitive to insulin. Therefore, the same food, but if eaten late at night, especially refined starch-rich foods, will easily cause a stronger increase in blood sugar than during the day.
Melatonin affects blood sugar control
At night, the body secretes melatonin to prepare for sleep. However, this hormone can also reduce insulin secretion or reduce the body's sensitivity to insulin. This makes glucose processing less efficient, leading to higher blood sugar when eating late at night.
Eating late at night disrupts the circadian rhythm
The body works according to natural biological clock, regulating sleep, hormones and metabolism. Eating near bedtime forces the digestive system to work during a time when it should be resting. This can lead to metabolic disorders and reduce blood sugar control over time.
