Because keto flu is real, and it sucks.

I recently started on a three-week tour of the ketogenic diet. I wanted to see both how effective it could be, and how it made me feel—I’ll report back in a few weeks. But right now I’m only three days in, and I can tell you one unexpected side effect: I’m experiencing a major energy drain. It wasn't entirely unexpected. Some people call this the keto flu.

I’m not going to lie, the past few days have been rough. I’ve felt foggy, tired, and hangry. Plus, my sugar cravings have been more intense than ever.

Apparently these are all symptoms of the keto flu, which is caused by a combination of carb withdrawal (it’s been said that sugar affects your brain in a way that’s similar to cocaine and heroin) and electrolyte imbalance from quickly losing water weight, which happens when you eliminate almost all carbs and processed foods. Apparently carbs hold a lot of water!

According to my frantic Googling, keto flu can be remedied by adding sodium and potassium to your diet, plus sticking it out for a few more painful days while you adjust, and drinking a lot of water.

 But while salt is easy to replace (just sprinkle a little extra on your eggs or meat), many potassium-rich foods are off-limits for people doing keto (think: bananas, potatoes, sweet potatoes, melon, beets, dried apricots, yogurt, beans, and lentils.)

I spoke with Cooking Light’s Food and Nutrition Director, Brierley Horton, MS, RD, and she said that most Americans—whether they’re on the keto diet or not—need more potassium in their diets because it helps regulate blood pressure and combats excess sodium in the body.
