What is Keto?

A ketogenic lifestyle in basic terms is getting our body to burn fats for fuel, instead of carbohydrates (when followed correctly). But how do we get into the metabolic state called ketosis? Let’s take a look.

A Better Understanding of Keto:

The present-day food lifestyle leans more towards high carbs, moderate protein and low fat. When the average person eats a meal high in carbs, their body's response is to take those carbs and convert them into glucose for fuel. Insulin is then produced to move the glucose from the bloodstream and into muscles, fat cells and the liver to later use. Glucose is the first source of energy the body will use when carbohydrates are present.

Key Points:

  • Carbs convert into an energy source called glucose.

  • Any glucose not burned off for energy is stored in the muscles as glycogen.

  • When glycogen stores are full, the body then converts and stores leftover over glucose as fat.

 

However on keto, things are the complete opposite. On a ketogenic lifestyle, your carbohydrate intake is kept very low, typically less than 20g a day. So when carb intake in this low, your body must use another form of energy to feed the brain, muscle and organs, the basic bodily functions that keep you alive, this is called your basal metabolic rate (BMR). The human body is amazing and is able to use fat as an energy source. This process happens in the liver where it takes fatty acids and converts them into ketone bodies, also known as ketones, which is then used as the body’s primary energy source. This metabolic process is known as ketosis, the ability for the body to shift from a carbohydrate fuelled body, to a fat burning body.

Key Points:

  • Carbohydrates intake is typically less than 20g a day while on a ketogenic lifestyle.

  • Our basal metabolic rate (BMR) is the rate of energy expenditure required for your body functioning at rest.

  • The liver produces ketones from fat, that is then used by the body as energy.

  • Ketosis is a metabolic process which allows the body to use fat as energy.

  • To allow the body to switch to a ketosis state, you will need to follow a ketogenic lifestyle for at least 2 weeks or maybe longer.
