The word ketosis often inspires misunderstandings or actually alarm in those trying to figure out what causes it and whether or not it’s a good thing. Here’s a simplified overview of ketosis.
Let’s move from an over-simplified ketosis diet description to moderately basic one. Ketosis implies that the body went from using carbohydrates as its way to get fuel to fats-almost solely.
But it’s a bit more included than that. Ketosis begins when there aren’t more than enough carbohydrates in the bloodstream to refill glycogen stores in your liver. What’s glycogen? The liver makes glycogen from carbohydrates as some sort of quick food supply for the body.
Too little carbohydrates mean your body needs another food source. Therefore the body uses fat, particularly essential fatty acids, instead. The liver breaks down fat into ketone bodies, generally referred to as ketones. When the liver releases these ketone bodies into the bloodstream for the body to use as energy, this is ketosis.
How Does Ketosis Happen?
When you eat carbohydrates, the body uses them for fuel and converts the rest into extra fat using insulin. This means that carbohydrates aren’t actually stored in the torso except for those kept in the liver as glycogen.
If you are using up all of the carbohydrates in your bloodstream and do not replenish them, your body will eventually need to use fat you are ingesting together with your food and fat stored in the body for fuel instead. It usually takes about 48 hours to induce ketosis.
