What Can Cause Flu

What Can Cause Flu

Have you heard of a weight loss diet that can cause flu-like symptoms? It may sound strange, but it’s actually a popular trend called the Ketogenic diet. This diet involves consuming high amounts of fat and very few carbohydrates in order to trigger a metabolic state called ketosis. While many people have experienced significant weight loss on this diet, it can also come with some unexpected side effects such as flu-like symptoms.

What is the Keto diet?

The Ketogenic diet, or “Keto” for short, is a low-carbohydrate, high-fat diet that has become increasingly popular in recent years. The goal is to switch the body’s main source of fuel from carbohydrates to fats in order to enter a state of ketosis. This is where the body burns fat for energy instead of carbohydrates, resulting in rapid weight loss.

To achieve ketosis, the diet typically involves consuming fewer than 50 grams of carbohydrates per day and getting the majority of your calories from fats such as avocado, cheese, nuts, and oils. This can be challenging for many people, especially those who are used to high-carbohydrate diets.

What are the flu-like symptoms?

While the Keto diet can be effective for weight loss, it can also come with some unwanted side effects, including flu-like symptoms. These symptoms can include headaches, nausea, fatigue, dizziness, and muscle cramps.

The reason for these symptoms is believed to be due to the body adjusting to a new fuel source. When the body enters ketosis, it undergoes a metabolic shift that can cause temporary discomfort as it adapts to burning fat instead of carbohydrates.

What can cause flu-like symptoms but not be the flu?

It’s important to note that flu-like symptoms can have a variety of causes other than the flu. In addition to the Keto diet, some of the common culprits include:

  • Viral infections: The common cold and other viruses can cause flu-like symptoms such as fever, chills, and fatigue.
  • Bacterial infections: Infections such as strep throat and pneumonia can also cause flu-like symptoms and require medical attention.
  • Allergies: Seasonal allergies can cause symptoms such as sneezing, congestion, and fatigue, which may mimic the flu.
  • Fibromyalgia: This chronic pain condition can cause symptoms such as fatigue, muscle pain, and sleep disturbance that may resemble the flu.

Tips for managing flu-like symptoms on the Keto diet

If you’re experiencing flu-like symptoms on the Keto diet, there are some things you can do to help manage them:

  • Hydrate: Drinking plenty of water can help flush out toxins and reduce symptoms such as headaches and fatigue.
  • Increase electrolytes: Since the Keto diet can cause electrolyte imbalances, it’s important to supplement with magnesium, potassium, and sodium.
  • Get enough rest: Your body needs time to adjust to the Keto diet, so make sure you’re getting enough rest and sleep.
  • Eat enough calories: While the goal is to consume fewer calories on the Keto diet, it’s important not to restrict calories too much, as this can make symptoms worse.
  • Consult a healthcare provider: If symptoms persist or worsen, it’s important to reach out to a healthcare provider for advice.


The Keto diet can be an effective way to lose weight and improve your overall health, but it may come with some unexpected side effects such as flu-like symptoms. If you’re considering the Keto diet, it’s important to do your research and talk to a healthcare provider to ensure that it’s right for you. And if you do experience flu-like symptoms, remember that there are things you can do to manage them and make the transition to the Ketogenic diet easier.
