Elevated ketone bodies are usually present in patients, who have Type 1 diabetes with ketoacidosis but may also be seen in healthy persons during long-lasting exercise, fasting or on low-carb diets. Intermittent fasting and low-carb diets are popular with people wanting to lose weight. This is a case report of a healthy 51-year-old woman, who admitted with a five-day history of abdominal pain with sudden worsening. She had recently initiated an intermittent fasting regime and followed a low-carb diet. She was diagnosed with diet-induced euglycaemic ketoacidosis, normal level of glycated haemoglobin and normal kidney function. She required isotone glucose infusions for 48 hours.
