INS and obesity due to melanocortin 4 receptor deficiency: A recent study101 suggests a high carbohydrate diet (60% carbohydrate, 20% fat, and 20% protein) is preferred for women with obesity who were insulin sensitive (fasting insulin <10 μU/ml) while a lower carbohydrate diet (40% carbohydrate, 40% fat and 20% protein) is preferred for women with obesity who were insulin resistant.
