Ask a Nutritionist: Why Am I Always Tired After Eating?

Why Am I Always Tired After Eating?

If you often feel wiped out and ready for a nap after lunch, you’re not alone. The post-meal slump — known as postprandial somnolence — is common, but it isn’t something you just have to accept. In many cases, that drowsy fog isn’t only about the food itself, but also about what’s happening in your gut. When toxins and waste build up in the digestive system, they can make meals harder to process and leave you sluggish. That’s where Flush GBI can help: by clearing toxins from the gut and supporting digestion, it helps your body use food for energy instead of exhaustion.


Why It Happens

Digestive load
After eating, your body prioritises digestion. Blood flow is diverted to the stomach and intestines, hormones are released, and energy is channelled into breaking food down. If your gut is sluggish or clogged with toxins, this process becomes heavier, leaving you more fatigued.

Carb-heavy meals
Simple carbohydrates spike blood sugar and then crash it, leading to drowsiness. While complex carbs can keep levels more stable, toxins in the gut can still interfere with glucose metabolism — exaggerating that “food coma” feeling.

Tryptophan-rich foods
Turkey, dairy, and other tryptophan-containing foods stimulate serotonin and melatonin, the neurotransmitters that regulate mood and sleep. Combined with a sluggish digestive system, this can intensify drowsiness.


Other Contributing Factors

  • Overeating: Large meals demand more energy to digest.

  • Poor sleep: If you’re already under-rested, food can tip you into sleepiness.

  • Gut health: An overloaded digestive system filled with waste makes it harder to efficiently absorb nutrients, leaving you tired instead of energised.

This is where Flush GBI makes a difference. By clearing blockages and removing toxins from the gut, it supports nutrient absorption and helps reduce the drain on your energy after meals. Instead of the slump, you get a smoother release of energy.


TL;DR

Feeling tired after meals is normal, but it’s often worsened by toxins and inefficiencies in the gut. Carb-heavy meals, tryptophan, and overeating all play a role, but a congested digestive system makes it worse. Flush GBI helps by cleansing the gut, removing toxins, and optimising nutrient absorption, so your meals fuel you rather than flatten you.
