Calories and Ketosis

I have a question regarding ketosis and calories I was hoping someone could answer.  When we are not in ketosis and we consume calories our body converts the calories into sugars that are used as fuel for energy.  My question is; when we are in keytosis and we consume calories, does our bodies convert the calories into keytones that are used as fuel for energy?  And is it the calorie deficit that causes our bodies to burn fat reserves for the balance of the keytones needed to reach our calorie requirements for the day?

Hey James!

Ok, so check this out. When we are carb fueled, we take in the calories and the glucose gets burned up for fuel. It burns fast and because our body can only hold a couple thousand calories of glucose, it isn’t a sustainable source of energy. So we need to refuel often. Cue the Ketone Diet! When things are functioning as they should and the glucose in the blood falls too low (because you reduce your daily carb intake), a hormone called glucagon is released. This will tell the liver to convert the stored glycogen into glucose and send it into the bloodstream. This process will also tell the body to start using fat for fuel (called lipolysis). When this happens our bodies create ketones! When we are in ketosis the ketone bodies do for our bodies what carbs do for someone not in ketosis.

Does that help?

Yeah, I think Becky is right.

You eat carbs, then your body converts those carbs to sugars for energy.

You eat healthy fats, then your body uses the fats and creates ketones for energy.

I simplified it, but I think that’s correct? Someone else might be able to confirm.

While I agree with both previous answers, I think the question is asking about calorie deficit.  If you eat too many calories, whether on a ketogenic diet or not, you won’t burn up more fuel than needed.  If you want to lose weight, you still have to have fewer calories than you would burn.  To lose weight, your intention is to burn more ketones as fuel.
