12:12 is a regular eating window. You’ll need to pay attention to your calories and activity.
What do you mean when you say “listen to my body”? It’s unlikely you are hungry after not eating for a few hours. You’re likely just used to eating and “craving” something out of habit. Very few people know how to really listen to their body. Your body won’t tell you it needs cake or cereal because it doesn’t.
Change takes effort and there will always be a period of discomfort while you adjust. It’s perfectly fine if you don’t want to fast but you’ll need to pick some other way to lose weight if that’s really your goal. It’s also perfectly fine to decide to remain where you are. You get to pick for yourself.
