Keto Diet Side Effects and Why They Happen

The Side Effects of Keto Diet

If you’re just starting with your ketogenic diet journey, you may experience some side effects as your body prepares to get into ketosis. Some people get serious keto fatigue, keto rash, and even keto flu. On the other hand, other people don’t. They go right into ketosis, adapting fast and encountering no problems. 

Keto Fatigue: This is exhaustion and headaches combined because of the shift in metabolic dependence.

Keto Rash: This is also called prurigo pigmentosa. It usually occurs on the neck and the truck.

Keto Flu Definition: This exhibits flu-like symptoms you get when you start your keto diet.

Why Do People Experience Keto Diet Side Effects?

What determines if you’re going to have the side effects or not is the amount of nutritional deficiencies in your body when you start keto and intermittent fasting. If you spent your whole life eating junk or sugar, then you are low in 2 main categories: B vitamins and minerals. Chances are, you’re going to have keto diet side effects. 

As your body adjusts to ketosis, you will experience vitamin and mineral deficiency symptoms like:

  • Fatigue
  • Blood sugar issues
  • Mood issues

How Can You Counter These Keto Diet Side Effects?

You don’t have to fear the keto diet and intermittent fasting just because of these side effects. You may not experience them at all! If you do start keto and intermittent fasting but have nutritional deficiencies, you simply need to add more minerals and B vitamins into your system. You can do this with nutritional yeast.

Nutritional Yeast Definition: Used as a condiment or ingredient to substitute dairy cheese. It’s full of vitamins, minerals, fiber, and protein. 

A keto diet can help you get into shape by using up your stored fat. With B vitamins and mineral deficiencies, though, you may experience the side effects of a keto diet -- that’s a fact. But you just have to amp up your nutritional intake and you’ll be all good.
