Side Effects That Indicate Your Body is in Ketosis

10. No symptoms

Some people experience few, if any, side effects of going on the ketogenic diet. That's great, and they are lucky, but how can they be sure they are in ketosis without experiencing symptoms? Urine test strips are very accurate for determining whether ketosis has kicked in. There are also monitors that use the breath, but these are generally considered less reliable.

Testing the urine isn't strictly necessary, though. It is generally accepted that people who limit their carbohydrate intake to 50 grams or less and eat 1.5 grams of protein for each kilogram of body weight will go into ketosis. Anyone who was instructed to begin the ketogenic diet but thinks they are not going into ketosis should talk to their doctor.
