What are the ways that you are reinforcing negative feelings toward your body?
Some ways are overt like weighing yourself, scrutinizing your body in the mirror, obsessively trying on clothes, wearing clothing that's either too big or too small, believing the negative self-talk in your mind.
Other ways are more subtle. Perhaps you don't honor your body's needs throughout the day. For example, putting off a bathroom break until later because you're busy or waiting until a certain time to eat a snack. By disregarding or minimizing your body's needs to are reinforcing the message that the needs are less important than other things.
Another example is forcing yourself to do things in the name of "health" but with the underlying mindset that you need to fix or change something about your body. Eating foods you don't like just because they're healthy. Exercise that feels like a chore because you're supposed to. By treating your body as if there's something wrong with it you are reinforcing negative feelings.
Take some time for honest reflection about how you treat your body. What if you were to treat it with compassion instead?
