Most people wake up every single day thinking their lack of willpower is why they reach for a muffin at ten in the morning or raid the pantry at nine at night. You blame your discipline, your stress levels, or your busy schedule. The truth is simple: your biology is running the show, and sugar is sitting in the driver's seat. When your diet contains refined carbohydrates and added sweeteners, your metabolism stays locked in a chemical trap. You are not weak; your hormones are reacting exactly as they were built to react to an unnatural surplus of refined fuel.
