What is Keto Diet?

The “keto” word in a keto diet means a diet which results in less production “Ketones” which are fuel molecules of a human body.

This is an alternative fuel for the body which is used when blood sugar or glucose levels are supplied less.


How are Ketones produced?

If you intake very few carbohydrates which are quickly broken down into blood sugar and moderate amounts of protein, this produces Ketones.

NOTE – Excess protein can also be converted to blood sugar, therefore it should be consumed in moderate amounts.

Ketones are produced in the liver, and from stored fat which is then used as fuel for the full body. Our brain is the hungriest organ which can consume lots of energy every day, so it can’t run on fat directly. It needs glucose or ketones.


When you follow a ketogenic diet, your entire body runs on fuel supply only on fat. This results in low insulin levels, and fast fat burning process. This diet helps a lot in making easier for your body to burn fat. This is most beneficial for you if you want to lose weight.
