After starting on a ketogenic diet some people may experience sick-like symptoms which might terrify them. You need not worry if this happens to you. Read this guide and understand why this happens

What is Keto flu

Keto flu is short term symptoms that may appear 3 – 7 days after starting a ketogenic diet.

Many people have gone for the keto diet to reduce weight as a recent study found that cutting on carbohydrate intake and increasing proteins and fats intake can actually help in reducing weight. But to some people, after starting on a keto diet some symptoms start to show up which are signs of keto flu.

Reducing carbohydrate intake causes a condition called ketosis, which involves the burning of fats in the body to provide energy. This can come as a shock to the body thus causing withdrawal-like signs which people call keto flu.

Symptoms of Keto Flu

Adjusting the body to low carbohydrates can come as a very big shock and thus can cause mild symptoms that disappear after some time. Keto flu symptoms are caused by a temporary imbalance in energy sources, insulin and minerals in the body.

Low carbohydrate levels cause a reduction in insulin levels which eventually causes an increase in sodium, potassium and amount of water released in urine which eventually causes dehydration.

Insulin is also involved in transporting glucose to the brain and thus when it reduces the brain will have insufficient fuel to do its functions and this can cause a headache.

Keto flu symptoms are not for everyone because some people just cope with the diet immediately but some experience the symptoms for either a shorter period or longer periods.

Keto flu symptoms include;

  • Nausea
  • Vomiting
  • Headache
  • Fatigue
  • Irritability
  • Sleepless nights
  • Constipation
  • Diarrhea
  • Weakness
  • Muscle cramps
  • Dizziness
  • Poor concentration
  • Rash
  • Dehydration
  • Low sugar levels
  • Stomach pain
  • Muscle soreness
  • Bad breath

These symptoms can even make some people quit their ketogenic diet but there is a need to have tips on how to go about if you experience these symptoms after starting on a keto diet.

Getting rid of keto flu

Most people put themselves through the ketog diet in order to reduce weight and also for health purposes but the keto flu symptoms can easily discourage. Here are the things you can do in order to get rid of the symptoms;

#1 Take more water

Drinking enough water is highly recommended if you are in a keto diet for health purposes and it also reduces the symptoms such as fatigue and muscle cramps.

Most people on a keto diet tend to lose water if they experience signs like diarrhea.

Generally, dehydration in a keto diet can happen when glycogen, a stored form of carbohydrates reduces thus causing water to be excreted from the body. Taking enough fluids and electrolytes is highly recommended to reduce the chances of dehydration.

#2 Eat a different dietary food

Changing the dietary food doesn’t mean quitting keto-friendly foods but actually including a different keto-friendly food in your diet and eliminating others that seem to be causing the symptoms.

Some fats might be the cause of the abdominal disorders you are experiencing, thus changing to a different fat-based meal will be the best trick.

On the other hand, high levels of medium level triglyceride have been found to be able to cause cramps, diarrhea, and vomiting. This will be reduced by consuming foods which contain long-chain triglyceride such as olive oil.

#3 Avoid strenuous exercise

Avoiding strenuous exercise while experiencing keto flu symptoms is very important to reduce the impact of the symptoms but light activities like walking and yoga should not be avoided as they help in improving the body’s adaptability to the keto diet.

#4 Eat more fiber

This will reduce constipation.

Eating vegetables with high fiber content or taking fiber supplements will be very appropriate for people who experience constipation.

#5 Get enough sleep

People who are adapting to the keto diet may experience sleeplessness which can cause keto flu symptoms to become worse.

If you experience a lack of sleep you can’t try to reduce caffeine intake, Practice switching off all lights in the bedroom to create a dark environment, take a bath before sleeping and try to get up early.

#6 Take medication

You can also visit a doctor for appropriate medication.
