Ketogenic diet is fat rich diet with less carbs which leads to ketosis. Also shortly named as keto diet, the diet involves having particular type of food which is able to provide a balance of nearly 75% fat, 20% protein and 5 % carbs.
The human body, in a normal scenario runs on glucose. However when your body does not have enough insulin (from carbs) to turn glucose into energy, your body needs another source and it uses fats to produce energy.
With the breakdown of fats, your body also produces some chemicals which are known as ketones. The chemicals made in your liver are sent to the bloodstream from where these are consumed as fuel by your muscles and tissues. The process of producing of ketones is called ketosis.
Owing to the drastic change in the diet, the body can experience some unwanted side effects. This can include issues like electrolyte imbalance, nausea, sleep disturbance or even a keto rash.
