That heavy, foggy feeling after lunch is so common it has a name: the food coma. Here is what is behind it.
7 common causes
| Cause | What happens |
|---|---|
| 1. Refined carbs | Fast blood sugar rise, then a dip |
| 2. Large portions | More energy goes to digestion |
| 3. Poor sleep | Lower resilience to the afternoon dip |
| 4. Dehydration | Mimics fatigue |
| 5. Alcohol with meals | A sedative effect |
| 6. Natural body clock dip | Alertness naturally dips in early afternoon |
| 7. Sitting still | Muscles aren't using glucose |
How to beat post-meal fatigue
Build a balanced plate
Half vegetables, a quarter protein, a quarter whole grains.
Eat carbs last
Starting with vegetables and protein can soften blood sugar rises.
Walk for 10 minutes
Muscles use glucose as fuel.
Drink water
Instead of sugary drinks.
Keep portions moderate
Stop when you are comfortably full.
Support your blood sugar
Gluco Extend combines bean extract, berberine and gymnema to support healthy blood sugar after meals.
See a doctor if you are very tired after most meals, or if fatigue comes with extreme thirst, frequent urination, blurred vision or shakiness, sweating and confusion a few hours after eating.
