ometimes a new scientific idea begins with a simple observation.
A pattern that doesn’t fit.
A question no one is asking.
A result that shouldn’t have happened—but did.
A newly published feasibility trial of ketogenic therapy in anorexia nervosa adds to a growing body of research exploring the relationship between metabolism, brain function, and psychiatric symptoms.
The study found that ketogenic therapy was feasible in adults with weight-restored anorexia nervosa and was associated with improvements in eating disorder symptoms, depression, anxiety, self-esteem, and daily functioning.
The study is small. And it is not the final answer.
But it is another signal that we may need to think differently about psychiatric disorders—not simply as disorders of thought, behavior, or willpower, but also as conditions influenced by brain energy metabolism and signaling, neurobiology, and physiology.
Every major shift in medicine begins with curiosity.
This work reminds us that some of the most important breakthroughs happen when we are willing to ask new questions—and follow the evidence wherever it leads.

Frank et al. evaluate the safety and clinical effects of a weight-maintaining ketogenic therapy in adults with anorexia nervosa who were either mildly underweight or weight-restored. The ketogenic therapy is well tolerated and associated with significant improvements in both eating disorder-specific...
