Buy unprocessed food and prepare it yourself. Don't add sugar. Eating processed food and even most restaurant food is eating food that's designed to make you want more, not satiate you.
There's a part of my brain that constantly thinks about food. It's like tinnitus. GLPs stopped that cold.
For me, stopping fast food, most restaurant/takeout food, and processed food such as bread, pastries, chips, cookies, and any prepared/convenient "snack" items drastically reduced how often I felt hungry or just wanted to eat for no apparent reason.
Tinnitus really is the best way I can describe it. I didn't even realize how pervasive it was until it shut off.
