Fatigue After Eating: Why It Happens and How to Fix It

Do you ever feel exhausted after eating a high-carb meal? You are experiencing postprandial fatigue or a sugar crash. When you consume too many carbs or sugars, they break down quickly and cause your glucose to rise steeply. Your body responds by sending large amounts of insulin to normalize your glucose levels. Sometimes this can happen too soon, causing a rapid decline that can tax your body.

Sugary snacks may satisfy us in the short run, but the increased blood sugar swing can make you feel more tired. Rather than reaching for the sugar, go for carbs such as those found in vegetables, fruit, and honey, which can provide a good source of immediate energy.

Does Getting Tired After Eating Mean Diabetes

Not necessarily. As highlighted above, feeling tired after eating is a common occurrence and happens for a variety of reasons, many of which are entirely normal. That being said, constantly feeling tired after eating can be a sign of diabetes, so if you are at all concerned then speak to your doctor, who can run some tests.

You Consume Stimulants Like Caffeine

There is nothing wrong with starting your day with your favorite cup of coffee. Coffee is one of those foods that can help us stay alert during the day. But overdoing the coffee mugs can cause the opposite effect and make you feel sleepy.

Why do you feel tired after eating or taking caffeine? Simple: Too much caffeine will eventually make the energy-boosting effect wear off. This happens especially during your next coffee break in the afternoon or after lunchtime.

Sugar And Its Affect On Sleep

The more sugar you consume, the more that it will affect your bodys ability to get in some quality sleep. While you sleep, your body goes through different levels of deep rest, and the most rejuvenating level is called rapid eye movement sleep .

The more sugar you have before bed, the less of a chance you have of staying in deep Rapid Eye movement sleep. Even if you do not fully wake up during the night, it can pull you out of REM sleep, affecting the sensations of feeling well-rested in the morning.

Tired After Eating Is A Normal Condition

Why do I feel tired after eating? Causes and prevention

In most cases, the tiredness that you feel after eating a food is a normal situation. Everybody will experience this thing. Here are some explanations on why feeling tired after having a meal is a normal condition.

  • Body Reactions Against Food That You Eat
  • This is the most ideal explanation on why you always feel tired after having a meal. You just feel tired because of your body reacts to the food that you already just ate. After you consume sweet or bakery products, thats pretty normal if you feel tired afterwards. Food that has a great amount of sugar causes your brain to release high amounts of neurotransmitter and serotonin hormone, which will make people tend to fall asleep.

    Besides, eating bakery products that contain flour will also make the blood sugar rise higher than normal. This thing will stimulate your pancreas to release great amounts of insulin, which will transports protein blocks called tryptophan from the bloodstream to your brain, then it will convert into serotonin that will make you feel tired and sleepy.

  • Digestive System Take Over Your Bodys Energy
  • Because your bodys attention is fully focused on digestion, the rest of your body tends to relax. This is why you feel tired and drowsy after having a meal. You might also feel tired after eating spicy foods. Your body needs to spend huge amounts of energy to digest spicy food. Also, spicy food will metabolize a chemical called capsaicin, which will make you feel tired.

    Why Do I Get So Tired After Eating

    Hormones That Make You Feel Sleepy After Eating Lunch

    There are different hormones that play a role in sleep and energy balance in the human body.


    Created by the human body naturally, Melatonin is a hormone that is responsible for regulating the sleeping and waking-up cycle for us. Did you know that darkness causes the body to produce more Melatonin? That is how our body knows that we need to sleep at night. There has been extensive research, and it has been found that blue light affects sleep in a way that it decreases melatonin production and signals our body to stay awake. Also, you must have heard of a term called ‘insomnia‘ – a state in which a person cannot sleep at all. Low levels of this hormone can cause sleep issues in the body. Hence, medical experts have come up with some melatonin supplements that anyone can take to get a good night’s sleep.

    On the other hand, there is one more hormone that influences our sleep cycle. Serotonin, a hormone released by the brain, is what makes a person drowsy.


    This hormone is accountable for balancing our mood, sense of well-being, energy, and happiness. Not only our brain but serotonin also affects our entire body. If you want to get a workaround for your sleep, digestion, and mood altogether, it is serotonin. According to scientists, this hormone can contribute to post-meal sleepiness. So, even if you keep a check on what you are eating for lunch and your meal size, an imbalance of serotonin might make you feel like hitting the bed post-lunch.

    • managing stress
    • getting sunlight exposure during the daytime
    • exercising

This is especially important if your fatigue interferes with your ability to work, attend school, parent, exercise, etc.

    Extreme Tiredness After Eating

    Overwhelming tiredness after eating can be a sign of an underlying medical condition. Diabetes is a health condition that affects your body’s production of insulin, which is needed to control your blood sugar levels. When you eat, your body begins to store sugar in its cells, but if you have diabetes, your body does not produce enough insulin to help control how much sugar is being stored. Spikes in blood sugar levels from eating can cause you to feel fatigued and lethargic, due to excess sugar in your bloodstream and cells. When enough insulin is once again produced to regulate your blood sugar levels, the glucose can be burned off as energy, thereby making you feel less fatigued.

    Bread Raises Blood Sugar Levels

    Most breads contain some form of carbohydrates in them. After you eat the bread, your body will start to breakdown the carbohydrates to be absorbed into the bloodstream.

    In those that do not have diabetes, insulin will naturally be produced to move the glucose from the bloodstream into muscle and fat cells to be used for energy.

    However, if you have diabetes, then the glucose will remain in the bloodstream, causing hyperglycemia. When your blood sugar is high you can start to feel the onset of fatigue tiredness.

    Patients with diabetes can see how their blood sugar is affected by various types of bread by easily checking their blood sugar with a glucose test strip.

    Certain breads may also have a high glycemic index, which means its digested very rapidly. This can cause a rapid spike in blood sugar, leading to the feeling of being tired.

    Other foods with a high glycemic index include:

    • White and whole wheat bread
    • White pasta and rice
    • Watermelon and pineapple.
    • Dried fruits such as dates, raisins, and cranberries.

    Its interesting to note that although whole grains, in general, have a lower glycemic index, wholewheat bread is still likely to make you feel tired after eating in the same way that white bread does.

    You are also more likely to feel tired after eating bread if you have a diet lacking in protein or healthy fats during your daily eating plan or if the bacteria in your gut and body are struggling to digest the energy source for some reason.
