In this coaching‑style talk, Charlotte Roycroft‑Davis explains that sustainable weight loss is governed primarily by the brain, especially the subconscious mind that drives habitual eating. She argues that most daily actions—including food choices—are automatic, with up to 90 % of behavior running on autopilot, making willpower‑based diets ineffective. To lose weight, the brain must be retrained so that healthy eating becomes an automatic habit, allowing people to enjoy nutritious food without cravings or comfort eating. She highlights how the modern environment—constant food cues, supermarket aisle design, and the sheer number of food‑related thoughts (about 200 per day)—reinforces unhealthy habits, creating a powerful external barrier to change. The solution involves recognizing these subconscious drivers, reshaping the environment, and deliberately forming new, healthy habits that the brain can adopt automatically.

The brain plays a huge part in weight loss, and it's important to understand what's gone so wrong up until now and how to recruit your brain to be on your side. It needs to be helping you to lose weight, not fighting against you. The key to sustainable weight loss is consistent healthy eating and being able to do that without willpower, cravings, or comfort eating. Healthy eating needs to become an automatic habit enabling you to enjoy eating good food every day and be able to naturally ignore the sweet stuff and the things that get in the way. Our eating and lifestyle habits are formed as we travel through life and are influenced by many things including our childhood experiences, After repeating the same habits for many years, they're ingrained deep in your subconscious mind and become automatic. This is true of so many other things you do during your day too. It's estimated that 90% of our daily behaviour is habitual and we do so much of it on autopilot. Anything from brushing your teeth to the times of day you eat. If you drive your car the same route every day, whether it be to work or on the school run, after a short time the car could drive itself because it's not you driving it, it's your subconscious. How many times have you got somewhere and have no idea how you got there? I do it a lot. How often have you eaten something and you have no idea why you ate it? So much eating is habitual and many people use the term mindless eating to describe this. But mindless eating suggests out of control, and that's not really the case because a big part of your mind is actually in control, and that part is your subconscious mind. The problem is when your subconscious is in control and running these ingrained habits, it's a real struggle to change things consciously by using willpower. You're basically fighting against a mighty power inside your head. The main reason diets don't work long term is because it's really hard to follow them consistently day after day, and yet making healthy food choices every day and being consistent about it is what you have to do to create new habits and lose weight. Remember, making consistent bad choices is what you did to create the bad habits in the first place. So your brain needs a bit of help and a bit of retraining. One problem is that the environment around you is set up to make changing your eating habits very, very difficult. Take a typical day. Did you know that you think about food 200 times a day, and most of the time you don't even realize you're doing it? Food triggers are everywhere, and retailers spend millions on unconsciously persuading you to buy their products. Take a supermarket. You wouldn't believe how much time, money, and effort is put into designing the aisles so that they influence your choices and get you to buy the things that they want you to buy. You may think you're in control, but really you are not.
