Diet culture creates a sense of guilt or shame for eating, attempting to suppress your appetite with caffeine or skinny teeth. Diet culture continuously tells us look a certain way or you're not good enough. And that can become an obsessive thought to the point where we are so obsessed with some particular characteristic or feature of our body that we're not able to function. You might also find that you feel anxious around foods and your mood changes based on how you feel about your body that day.
