Client presented with clinically significant depression and reported feeling irritable. Nutritional analysis of diet suggested client was overeating some macros and under eating others. Nutrition therapy was used concurrently with psychotherapy. No ketogenic diet was initiated. Instead we discussed elimination of processed foods and emphasized a nutrient dense diet high in micronutrients and essential amino acids, and some supplementation. Client reported feeling better with more stable mood. Episodes of anger decreased from being several times per week to infrequent. Diagnostic criteria for depression was no longer met. And client notices that when she eats better she feels more energy and less overwhelmed. – (Female, late-teens; Depression)
