It sounds shocking to be told never to eat sugar or flour, but this isn't just another diet telling you what not to eat. In the Bright Line Eating book, Susan explained that Bright Line Eating is designed to shift eating behaviours from the prefrontal cortex (decision-making part of the brain), to the basal ganglia (the part of the brain where things are automatic). It does take willpower to begin and set up, but after consistent repetition, it requires no willpower at all because eating becomes automatic.
Research shows it takes about 66 days to form a new habit, so if you feel like Bright Line Eating might be for you, give it at least two months. Reading the Bright Line Eating book is helpful, and Susan also offers a 14-Day Challenge to get you started. After that, there's an eight-week boot camp so you can get the support you need to be successful and live "happy, thin, and free."
