Keto flu is a short-term reaction some people experience when starting a keto diet.
It is not an illness, but a response to changes in how the body processes energy and fluids.

When carbs are reduced:
Insulin levels drop
The body releases stored water
Electrolytes (like sodium and potassium) may decrease
These changes can temporarily affect how you feel.
