From Feast to Snooze: Understanding Food Coma

 Understanding Food coma



“Have you ever struggled to concentrate or keep yourself awake after a big meal? You are not alone in this, we’ve all experienced it."










This incident is referred to as “Food coma” or “Postprandial somnolence" also known as a “post lunch dip”.

It is the state of drowsiness and lethargy that many people feel after eating a large or heavy meal. 

Many have been wondering why they feel sleepy and weak right after a meal or that certain food causes them to sleep or some even attribute it to the reduced alertness experienced by many during mid-afternoon. but is it true?




The common explanation for Food coma has been the redistribution of blood flow from the brain after meals but recent research suggests that it is post-meal fatigue linked to hormonal changes and of the activation of sleep centers in the brain.



 But you may ask yourself what is the cause? 


A. Meal composition:



A diet high in refined carbohydrates can spike your blood sugar levels followed by a subsequent crash, leading to fatigue and sleepiness. This is because the body releases a surge of insulin to deal with the sudden increase in blood sugar, which can lead to a drop in energy levels.

Similarly, a high-fat meal can also contribute to sleepiness as it takes longer to digest, requiring more energy from the body.







B. Hormonal changes:


Eating triggers the release of serotonin; a hormone that is multifunctional that has several crucial roles which includes mood regulation, promoting restful sleep, pain perception and regulating appetite to prevent overeating when you are full, and digestion.






C. Meal size:




Duration:

There is no exact duration agreed upon by many but literature mentions 1 hour or between 2-3 hours after a meal. From a study conducted on adolescents to assess the effect of food coma on cognitive performance, it showed that most of the effects are concentrated in the hour following meals.



Effects and consequences of food coma


Food coma affect our body ranges from immediate to long-term such as:


  • Drowsiness and fatigue: obviously
  • Reduced performance at work or school due to impaired concentration and reduced alertness which result in difficulty completing complex tasks.
  • Discomfort: Overeating causes bloating, indigestion and generally physical discomfort.
  • Weight gain: in the long-term, eating heavy and particularly high carb diet leads to weight gain
  • Increased risk of metabolic disorders like insulin resistance, type 2 diabetes and other metabolic disorders
  • Perturb sleep pattern: Overeating especially close to bedtime disturbs your sleep and affects the quality of sleep.
  • Stress and Guilt: the physical discomfort can leave a person feeling overeating and the potential weight gain can contribute to anxiety overtime.


Tips to prevent Food coma




  1. Eat a balanced diet including vegetables, proteins and healthy fats. Finding shows that the effects of food coma worsens when a meal is high in carbohydrates.
  2. Do not go for sugary snacks as this will again spike the insulin which will lead to tiredness or further triggers hunger.

  3. Take     walk or incorporate light physical activity to aid digestion and help you stay alert.
  4. Eat mindfully: If you are sleepy after a heavy meal, consider the portion size, listen to your body’s hunger and fullness cues.

  5. Chew gum. This can increase your alertness, curb craving and overeating and eventually reduce the effects of food coma.
  6. Stay hydrated to aids digestion, stabilizes blood sugar levels, and enhances circulation, helping to prevent feelings of lethargy after eating

  7. A daytime nap may help improve cognition, prevent food coma and restore productivity.

Lastly, as Jackie Chan famously said "Coffee is a language in itself." Have a cup of coffee to minimize the effects of food coma on a high-stakes.









The next time you feel drowsy after dinning, or as we've called it you come from feast to snooze you'll understand what's happening and how to handle it.


We hope this has been helpful!!😎😊

When you consume a large meal, your body diverts more blood to your digestive system to help in the digestion of the large meal you’ve consumed and this reduces the blood flow to the brain which makes you feel sleepy.

IS THERE SUCH A THING AS "GOOD SUGAR"?

IS THERE SUCH A THING AS “GOOD SUGAR”? Sugar is everywhere—from the natural sweetness in fruits to the added sugars in packaged snacks. But when it comes to health, the story isn’t as simple as “good” versus “bad.” So, is there really such a thing as good sugar ? Let’s unpack this. Many people believe that sugar from natural sources, like a fruit smoothie, is “good,” while sugar from cakes or biscuits is “bad.” In reality, from a calorie and blood sugar perspective, your body treats sugars from fruit smoothies, cakes, or honey in much the same way, once digested, they contribute similar amounts of energy and can cause similar glucose spikes. A glucose spike happens when the sugar level in your blood shoots up quickly after eating, especially from foods like sugary drinks, sweets, or white bread or simply carbs.  However, the way sugar is packaged in food matters a lot for your health, and this is where the difference between naturally occurring sugars and added sugars comes in.

False or Fact: The Common Foods We've Been Lied About

False or Fact: The Common Foods We've Been Lied About   Let’s be real — nutrition advice can feel like a never-ending game of telephone, with information getting twisted  and misunderstood as it's passed along. Many of us have seen a food go from a normal everyday staple to a villain overnight, only to be welcomed back years later as if nothing happened. For instance, butter was tossed aside for margarine(only for margarine to later be outed as worse because it contains trans-fats). We live in an era where myths often outweigh facts, and misleading headlines spread faster than actual science. In this short blog, we’ll explore three common food myths that lingered far longer than they deserved, myths that shaped the food market, influenced dietary guidelines, and even changed what we put on our plates. And of course, we’ll highlight the facts around them. It’s time to separate fact from food fiction. 1. The egg-xtremely misunderstood Egg Myth : Eggs are bad for your heart hea...
