All antipsychotic medications (Abilify, Zyprexa, Risperdal, Seroquel, Clozapine, etc.) can contribute to high insulin levels and insulin resistance —a hormonal shift in metabolism that makes it harder for the body to process carbohydrates. Over time, insulin resistance can lead to weight gain, type 2 diabetes, heart disease, and even Alzheimer’s disease. In stark contrast, ketogenic diets have many positive side effects; they lower insulin levels and improve insulin sensitivity, reversing signs of insulin resistance and associated conditions.
