Recent studies have revealed that cutting calories to lose weight raises cortisol, a hormone known to interfere with thyroid hormones and insulin, cause leptin resistance, and more. High-protein, low-carbohydrate diets are also thought to consistently raise cortisol levels as well. All of this contributes to weight gain long-term, regardless of short-term apparent success. Diets make you fat.
