A ketogenic diet is a low-carb, high-fat diet. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis. It has many health benefits including weight loss. 

A ketogenic diet reduces seizures in children, sometimes as effectively as medication. Because of these neuroprotective effects, it also seems to have possible benefits for other brain disorders such as Parkinson’s, Alzheimer’s, multiple sclerosis, sleep disorders, autism, and even brain cancer.

However, there are no human studies to support recommending ketosis to treat these conditions.

Like many other diets, the keto diet also has some side effects and complications. When you start ketosis, you may experience symptoms like nausea, gastrointestinal distress, and fatigue among others.

These symptoms are called keto flu. You can minimize the effects of keto flu by drinking plenty of water and getting plenty of sleep. 

Lack of fiber in the keto diet can also cause diarrhea. Such a condition can also be caused by an intolerance to dairy or artificial sweeteners, the things you might be eating more in a low-carb lifestyle. You can overcome diarrhea by adding supplements like vegetables.

If you are taking medications for diabetics, or high blood pressure, it is better to consult a doctor before starting a keto diet. Keto diet is one of the best diets if you are following it in the proper way.
