Have you just been ready to move mountains but felt exhausted after eating? It is quite real because food can cause fatigue. This phenomenon has the name “food coma.” And it can appear through:
- Eating a lot of food. Since the body needs energy for its digestion, it lowers your activity;
- Consumption of carbohydrate products with a high glycemic index. After all, they increase the level of sugar in the blood;
- Eating a variety of foods at one time. The body can not digest it quickly, so low energy after eating.
Digesting food is hard work for our bodies. As soon as food enters the stomach, many organs and systems come into play. Their job is to digest food, select the necessary elements and deliver it to the concert areas of your body. All this requires a lot of energy. So, a person can be exhausted after eating. Besides, such a feeling can also be due to insulin. When you eat, insulin levels spike to ensure your blood sugar is regular. And when this process is ready, insulin levels drop, which can cause of fatigue.
What Causes Fatigue After Eating?
If you sometimes want to lie down after dinner, nothing is wrong with that. But if you feel extremely tired after eating, this is a reason to look for the cause more carefully. Usually, a person should feel cheerful after food. After all, it gives the body the necessary energy. But sometimes, after a heavy lunch, lethargy and drowsiness appear. It can be due to the body’s efforts to digest the incoming food.
But note that afternoon fatigue should not be long and constant. If this feeling occurs often, consider the reason for it. Feeling bad after eating can be a consequence of improper nutrition. Or it can signalize about serious health problems. Extra symptoms can even go with such tiredness after eating. Among them are lack of physical strength, dizziness, and changes in blood pressure. But why does this happen to our bodies after eating? Read the following reasons:
1. Circadian Rhythms
Low energy after eating occurs at lunchtime but not after breakfast or dinner. It happens through circadian rhythms. It is they who cause fluctuations in the level of blood pressure. And different hormones fluctuate throughout the day. Closer to 1-3 p.m., a person becomes drowsy. Sleepiness appears even if you skip lunch. But after eating, you want to sleep precisely harder. Thus, your fatigue can manifest exactly because of such a physiological feature.
2. Lots Of Tryptophan
Eating foods rich in the amino acid tryptophan can cause a feeling of exhaustion. It happens significantly often a few hours after leaving the table. Why? Tryptophan stimulates the production of serotonin and melatonin in the body. They are the sleep hormones. Thus, you feel sleepy as soon as tryptophan exceeds its bridge in the body. Accordingly, this leads to a loss of physical strength and tiredness.
3. Overeating
Remember how you ate on holiday at a big table until you had to tug on a fly to open it? How did you feel after that? Probably you felt weak and tired after eating. And all because the more you eat, the more energy your body needs to digest. So, if you habitually overeat once a day, it will not have good consequences. After all, the body does not have the super ability to digest food in seconds. And when your stomach gets overeating, you are exhausted after such dense eating. Therefore, reduce the size of portions and eat foods rich in protein to avoid this.
4. The Rate Of Food Consumption
It takes time for the brain to send a satiety signal to the stomach. So, the food consumption rate plays a role in determining the satiety level. A study shows that people who consume food more quickly have a larger appetite. Accordingly, they eat 25% more than those who consume less food. And the more food you have in your body, the more energy your stomach takes. It is partly due to the hunger hormone, which plays a role in appetite regulation. When you eat too fast, the brain does not have time to send signals, and hormones regulate this process. Accordingly, you feel weak and tired after eating.
5. Diseases
Diabetes, food intolerances, and allergies can cause a decrease in energy after eating. If a person with type 1 or type 2 diabetes feels tired after eating, this can be a symptom of hyperglycemia. It is high blood sugar. This condition worsens if insulin levels are low to transport sugar. Food intolerances and allergies can affect digestion or other body functions. When you eat food that your body perceives as foreign, the immune system fights hard against it. And as a result, you feel extremely tired after eating.
6. Alcohol
Visible weariness is even more noticeable if you drink alcohol while eating. It suppresses the nervous system and causes drowsiness. After intoxication, getting enough sleep and replenishing energy reserves is usually impossible. Alcohol stimulates the release of adrenaline. And this hormone instantly mobilizes the body. About 20% of ingested alcohol absorbs in the stomach and about 80% in the small intestine. Thus, when you consume it with food, alcohol affects the body faster. It also delays food digestion, leading to tiredness after eating.
7. Hidden Food Intolerance
Food intolerance or food allergy has an association with unpleasant gastrointestinal symptoms. It can be stomach cramps or diarrhea. But sometimes, food intolerance manifests itself in the form of drowsiness. And a person can not even suspect it.
For example, if you have gluten sensitivity or celiac disease, you can be exhausted after eating gluten-containing products. Because they can cause an allergic reaction. Besides, it limits your body’s ability to get enough calories from food.
8. Drinking Coffee In The Morning
Your morning cup of coffee is invigorating, but not for long. The stimulant effects of caffeine usually have a half-life. It happens from 1 to 5 p.m. after it enters your body. So, the impact of coffee drunk at 8 a.m. will end just in time for the lunch break. Thus, feeling weak and tired after eating can not be due to eating lunch. But it can be due to drinking coffee in the morning.
