Doctors may tell you to worry about something called ketoacidosis if you go on a ketogenic diet. You only need to worry about ketoacidosis if your ketones are high and your glucose is ALSO high. This is not good and can sometimes occur in diabetics on high-sugar diets. This is very unlikely to occur on a carnivore diet because you don’t eat enough carbohydrates or sugar to raise your glucose. It really doesn’t appear possible to go into ketoacidosis if you aren’t consuming carbs and sugar. If you’re concerned about this anyways, you can buy a ketone and glucose monitor to monitor your levels of both.
Something to consider regarding ketoacidosis is that diabetes often changes the function of the liver and causes gluconeogenesis (excessive production of sugar.) This means that many advanced diabetics can still have high blood sugar even after eating very low carbohydrate food. The body can turn excess protein into glucose. Ketoacidosis is therefore possible and everyone should know the symptoms because it would be a very serious condition for those people.
