The keto flu is a common side effect experienced by those who are on the ketogenic diet. It is a temporary condition that typically lasts for a few days up to a week. The symptoms of the keto flu are similar to those of the regular flu, including fatigue, headache, dizziness, nausea, irritability, and muscle soreness. These symptoms are caused by the body’s transition from burning glucose to burning ketones for energy.
One way to prevent or reduce the severity of the keto flu is to gradually decrease carbohydrate intake over a period of several days before starting the ketogenic diet. This can help the body to adjust more smoothly to the new diet. Drinking plenty of water, consuming adequate electrolytes, and getting enough rest can also help to alleviate the symptoms of the keto flu.
It’s important to note that the keto flu is not a serious condition and is a sign that the body is adapting to the new diet. Most people will experience the symptoms for a few days and then feel better. However, if the symptoms persist or worsen, it’s important to seek medical advice.
