I don't even care if "food noise" is a trendy or overused term, it's a real thing and I never knew I even had it. Looking back, I'm amazed that I'd spend so much time thinking about what I would eat and when, and then half an hour later, I'd either want to eat a little more or begin planning what I would eat at my next meal. Even if that next meal was just a snack (and one that I didn't even really need!).
Every now and then I stop and think about it like it was happening to another person who wasn't me. I used to travel a lot for work and boy, making sure I had snacks for the flights, wondering if I had time to grab something at the airport or during a connection was so time and mental energy consuming. It was almost always healthy enough food, which is why my weight never got as bad as it might have, but still, the fact that thinking about food all day was just a normal part of my life is so depressing. Now, not only do I eat and then stop thinking about food once I'm done, but I often will eat a meal later than I intended because I was doing something else and forgot.
For me, the scientific miracle of pinpointing the chemical that feeds the food noise (pun!) and creating a drug that quells it, is why this is so life changing.
