Some people report headaches or light flu-like symptoms. This is often referred to “The Keto Cold”.
Personally, it felt like an allergy attack. It passed in a couple of days and I am so happy I hung in there!
Nothing has felt so good as eating clean healthy keto food.
I’ve never heard of anyone getting a fever during this time.
however, if one experiences prolonged diarrhea, fever or vomiting, it’s best to contact your doctor to rule out other causes.
