10 Keto Flu Symptoms
Symptom #6: Irritability
Getting easily provoked and irritated for even unjustifiable reasons is a common keto flu symptom. The irritability can be caused by the general adjustment that the body undergoes as it shifts from using carbohydrates as the major source of metabolic energy to ketones.
Carbohydrates also have other biological effects that promote feelings of calmness and contentment. A change to a low-carbohydrate diet may, therefore, provoke irritability. One example in this respect is the effect that high sugar foods have on the reward system as described elsewhere. The resultant reduced activity when transitioning to a keto diet can come along with episodes of irritability.
