Ketosis is when ketones fuel your cells. When you're in this metabolic state, your blood ketone levels are higher than usual. This is completely normal and healthy, even . People try to induce ketosis by following a ketogenic diet. That's because ketosis helps people lose weight, control blood sugar, and prevent dangerous diseases.
Ketoacidosis, on the other hand, is when the body makes too many ketones, turning the blood acidic. Ketoacidosis is considered a medical emergency. Luckily, it is rare in healthy people and is never caused by diet. Ketoacidosis usually happens due to untreated type 1 diabetes, alcohol dependence, and starvation.
For the most part, you don't have to worry this could happen. A healthy body keeps ketone levels within normal ranges with the help of insulin, a hormone that signals the liver when to stop producing ketones.
However, if your body isn't making enough insulin (diabetes), you are at a higher risk of ketoacidosis. The same can hold true if you take insulin-lowering medication. Speak to your doctor if you have diabetes and plan on going keto.
