The keto flu & side effects
Once you’ve been on a keto diet for a few weeks or more, you will likely feel great and have lots of energy. However, the first few days to weeks can be tough, as your body switches from burning mostly glucose to burning mostly fat for fuel.
Keto flu
When your body makes this shift, you may experience what’s commonly known as the “keto flu.” It happens as a result of changes to your body’s balance of fluid and minerals when you begin eating very few carbs.
Symptoms of keto flu include:
- Fatigue
- Headache
- Irritability
- Lack of motivation
- Difficulty focusing (“brain fog”)
- Dizziness
- Muscle cramps
- Less energy for intense exercise
Fortunately, you can minimize these symptoms before they start by replenishing fluids and salt. Good strategies include drinking a cup or two of salty broth or being liberal with the salt shaker.
Also, remember that these symptoms are temporary. As your body adapts to its new way of getting energy — from fat instead of sugar — symptoms should quickly subside
