Why do you feel tired after eating?
A spike in blood sugar level is the main culprit of tiredness after eating! There is research shows that people who ate a diet that led to drastic blood sugar changes said they felt more tired on average than those who ate foods that gradually increased blood sugar . This suggests that a heavy diet rich in simple carbohydrates, and highly processed foods that lead to spikes in blood sugar levels may be more likely to cause sleepiness.
When carbohydrates are ingested into the human body, they are broken down into glucose and enter the bloodstream. The pancreas will then releases insulin which binds to insulin receptors allowing glucose to enter the cell for immediate energy usage or storage, which controls the increase in blood sugar level.
When you consume foods high in refined carbohydrates, blood sugar spikes, and in order to control blood sugar levels, insulin has to be secreted in large amounts, which causes insulin receptors to fail to respond and blood sugar ends up failing to enter cells as usual. At this time, the pancreas will secrete more insulin, forming a vicious circle. When the human organs are overburdened and cannot rest normally, people will feel drowsy. At the same time, insulin inhibits the breakdown of protein and promotes the formation of melatonin, which also makes people feel drowsy.
How to avoid sleepiness after eating?

Consume high-fiber food
High-fiber foods, such as cereals, whole grains, fruits and vegetables are complex carbohydrates that generally take longer for your body to break down, which gradually allows glucose to be released into your blood, which keeps blood sugar levels in a stable state.
This can make the body have consistent energy for a long period and improve work efficiency.
Cut down sugar consumption
Foods with high sucrose content such as sugary desserts break down into glucose in your body, which increases your blood sugar levels.
Your body will releases insulin to control the sudden spike in blood sugars. The increase in insulin makes your brain produce sleep-inducing melatonin and the neurotransmitter serotonin, which can make you feel sleepy.
