How Does Keto Flu Feel?

Choosing to follow a low carb diet is a well-known and successful method for initiating weight loss and improving overall health. However, individuals may encounter difficulties when transitioning to a low carb, high protein diet, and this is often referred to as the keto flu.

What exactly is Keto Flu?

Keto flu is a term used to describe a range of symptoms resembling the flu that individuals may experience when they first adopt a ketogenic diet. This occurs as the body adjusts to utilizing fat as its primary source of energy rather than carbohydrates. While not everyone may develop keto flu, it is quite common, particularly in the first few days or weeks of starting a low carb diet.

Signs and Symptoms of Keto Flu

While the symptoms of keto flu can differ from person to person, some common signs include:

  • Headaches
  • Tiredness and exhaustion
  • Nausea
  • Vertigo
  • Irritability
  • Brain fog

These symptoms often occur as the body adjusts to utilizing ketones as its primary source of fuel instead of glucose. The transition period can be challenging for some individuals, but it usually resolves within a few days to a few weeks.
