As I have mentioned previously about the state of being in mild ketosis during the day, which implies the use of ketones, now might be a good time to further explain what the use of ketones to fuel our energy levels really means, as opposed to being traditional “sugar burners.” First, a couple of quick, simple definitions to help you understand this topic better:
Glucose = A type of sugar, main source of energy for most people
Insulin = A chemical excreted by the pancreas to transport sugar into the body’s tissues
Ketone bodies = A type of energy source produced in the liver as a by-product of fat metabolism
A traditional “sugar burner” is mostly fueled by the glucose provided from any carbs eaten. When we eat, the hormone insulin kicks in to dispose of the nutrients, which are now in the blood, and send them wherever they are needed. If we eat too many carbs (healthy or not), quickly after a spike of energy, we feel tired because (among other things) a lot of insulin has to be produced to dispose of this excess sugar. Ever wonder why you felt like taking a nap after that lunch you had? That’s the spike of insulin talking. If we are “sugar burners,” we have those ups and downs on a regular basis throughout the day.
Now if we start to consume more healthy fats throughout the day and limit our carb intake, we don’t have to deal with all those ups and downs that excess sugar and overproduction of insulin trigger. Isn’t it a nice thing not to feel like taking a nap after lunch, especially when we can’t? Healthy fats keep us more satiated for longer periods of time.
So we have the healthy fats that we consume and we have the ketone bodies, both to fuel our energy levels in a more linear fashion when we become fat-adapted. Eating healthy fats means consuming foods like avocados, olives, nut butters, certain oily fish, grass-fed butter or ghee, coconut oil, MCT (medium-chain triglycerides) oils, extra-virgin olive oil, and avocado oil.
Ketones are a by-product of body fat that is tapped into if we fast or if we limit our carb intake to a bare minimum. If we are keto-adapted, we can use those ketones (we are in ketosis) but, if we are “sugar burners,” those ketones are close to useless. MCT oils are the only oils that also increase ketones in the body, such as the Brain Octane oil I blend in my coffee. MCT oils are processed right away by the liver, so a surge of energy can be felt pretty much immediately, especially if consuming C8 MCT oil. This is another way to increase ketones in the body and reach a state of mild ketosis without literally having to fast.
Being able to utilize ketones as fuel to power ourselves each day is an awesome tool at our disposition to better our lives.
