Study links Atkins diet to health risk

LONDON – The popular Atkins diet could be linked to a life-threatening complication which one woman who claimed to be following it developed, according to doctors who published a case report on it today in a British medical journal.

The Atkins diet calls for restricting carbohydrates to achieve weight loss, then gradually adding them back in.

Doctors from New York University wrote in The Lancet journal of a 40-year-old woman who developed a dangerous condition called ketoacidosis, a buildup of acids called ketones in the blood which can lead to patients falling into a coma.

However, some outside experts said the case is rare and does not reflect a major health threat associated with low-carb diets.

“I think this is an isolated case. The idea that serious ketoacidosis could be triggered by a low-carb diet does not happen very often,” said Dr. Paul Clayton, president of the forum on food and nutrition at the Royal Society of Medicine in London.

Dr. Abby Bloch, vice-president of programs and research at the Dr. Robert C. Atkins Foundation – a medical research charity run by Atkins’ widow, Veronica – said ketoacidosis was not triggered by diet and could only occur if the patient had an “abnormal clinical metabolic condition.”

The patient, who was not identified, was admitted to an intensive care unit for four days after becoming short of breath. Before being hospitalized, she had lost her appetite, felt nauseous and was vomiting four to six times a day, the doctors wrote in the paper.

Tests confirmed ketoacidosis.
