My best advice is that it IS okay to eat junk once in awhile, we're not going to overly moralize food, but when the nutrition is questionable it become even MORE important to listen to hunger cues and STOP EATING when the hunger signal goes away. The problem wasn't pizza and pretzels, it was over stuffing on pizza and pretzels, regardless of the signals the body was giving that hunger was sated long before then.
I really struggle with this concept too. But I'm becoming more convinced that it isn't the diet that needs the change, necessarily, but those of us who change our food and magically expect it to change our mindsets, too. If we don't change the way we relate to food, maintenance will continue to be a battle.
You'll get it off soon enough

but I encourage you to do mental inventory on what you think entitled you to abuse your body with too much food, when the only defense the body has is to gain fat? Some hunger scale measuring may be really helpful to you, I know it has been to me! I eat for many reasons besides hunger, including boredom and 'I deserve it'. But no reason for eating is valid besides hunger and I'm really taking a step back from all eating that isn't physiologically demanded and stopping when satisfied, and not stuffed. It's so simple, but kind of mind blowing, to reassociate myself with those physical cues.
That might be something you'd benefit from, too?
