Ketone bodies are an incredibly efficient, and alternative energy substrate for the body & brain to use as fuel rather than glucose.
You will hear conflicting opinions on ketosis, all of which may be science based, leaving you to wonder who to trust and what advice to follow.
Every person’s physiological & metabolic condition is different. A state of ketosis and reaching that state requires individual fine tuning based on a person’s current health as a whole. Individual assessment is required. Your genetics- genotype & phenotype, hormonal status, stress, metabolic damage- all come into the equation when trying to achieve ketosis. What works for you may not work for another- and that's Ketosis. However in saying that, the basics are the same; Healthy Fat, Low Protein and Very Low Carbohydrates.
When you are in ketosis you will change how your body feels and most importantly, how your body uses its energy.
Your body can function in two ways-
Glycolysis- most of us are ingesting carbohydrates- our pancreas then responds with a release of insulin to give us energy. This metabolic process is called Glycolysis.
Ketosis- if you stop eating carbohydrates, your pancreas does not need to release insulin, so it can release another hormone called glucagon. Glucagon signals to your body to break down fats which are sent to your liver - your wondrous liver, to produce ketone bodies. You are now using your fat stores as your energy rather than the carbohydrates you ingested!
Percentages of macro-nutrients can vary with each individual and their reason for doing the ketogenic diet. The Ketogenic protocol that is used by doctors to treat epilepsy is sometimes up to 80 and 90% fat! As you can imagine, guidance of an experienced practitioner is important to ensure the correct choices and right amounts of heart healthy anti-inflammatory fats are being consumed. An easy example of the wrong fats is if someone was to recommend you use canola oil or margarine-margarine is not even a real food and Monsanto developed Canola oil- say no more! Some people reading this may think it preposterous I even mention margarine- but trust me, I attended a 2 days seminar in Melbourne in 2016 for Dietitians- canola oil AND margarine are apart of their protocols.
A ketogenic diet/lifestyle is referred to as many different names- ketogenic diet (KD) low-carb diet (LCD) low-carb high fat (LCHF) diet, even a modified Atkins diet (MAD) but It is not the Atkins diet. A Ketogenic diet is Healthy Fat Low Protein and Very Low Carbohydrates
