A ‘keto’ diet – sometimes called a “Very-Low-Carbohydrate Diet”, a “Ketogenic Diet” or “Atkins” – is a diet that causes your body to produce a certain level of ketones through dramatically reducing your carb intake and once you reach this level, you are in “ketosis”.
So now you may be asking, ‘what is a ketone?’. They are just a class of natural chemicals that are normally floating around in your blood and your cells. Usually, your body produces these chemicals in tiny amounts but you will make more of them if you don’t get enough carbohydrates in your diet.
