Summary:
- The "keto flu" is a set of symptoms that some people experience when they start a ketogenic diet, which involves drastically reducing carbohydrate intake.
- The keto flu is caused by the body's adaptation to using fat as its primary fuel source instead of carbohydrates, leading to changes in fluid and electrolyte balance.
- To prevent or reduce the keto flu, it's important to stay hydrated, replenish electrolytes, and gradually transition to a ketogenic diet rather than going "cold turkey" on carbs.
