Enter: the baked good.
One day, I had grabbed a muffin from crafty, but I guess I got caught up in something, so I didn't eat it immediately, so it stayed next to me at my table. And once I got less busy, I didn't eat it, it just sat there. And sat there.
But because it sat there, I didn't grab other things to eat. I had food near me, so I didn't feel the need to grab other snacks. I had a snack, so why grab more? And it's really helped. When I do grab a snack, it immediately goes into my backpack. Out of sight, out of mind, and I get a snack for when I get home.
That's really it. Just my little mental tricks to not snack during the day. Passing on the knowledge if you want to curb unnecessary snacking during your day.
