Imagine you really like eating your favourite snack, like chocolates or chips. Now, imagine that you like eating that snack all the time, even when you're not really hungry or need the snack. That is called overeating - when you eat more food than your body needs.
Compulsive overeating is when you eat too much food all the time, and you feel like you can't stop eating no matter how full you feel. It's almost like your brain is telling you that you need to keep eating and eating, even if you don't want to or know it's not good for you.
Overeating can make you gain weight and feel unhealthy, and it can also make you feel sad or ashamed. It's important to talk to a grown-up if you or someone you know feels like they can't stop eating, so they can help you get the support you need. There are also lots of ways you can learn healthy eating habits, like eating more fruits and veggies, drinking lots of water, and taking breaks from eating when you start to feel full.
