I did this the opposite way - lost 50#, which I've kept off for almost two years now, and then came here and started getting the "cha-ching" instinct installed.
Agree on the calorie-counting for a bit. Even if you commit to doing it for a week, it makes you think about having to track each food as you're contemplating putting it in your mouth. And it will give you ideas of what you can cut from your food "budget." Repeat as needed to reinforce habits. As mentioned, My Fitness Pal or Spark People websites/apps are way easier than tracking your foods in a spreadsheet.
Eat lots of low-cal veggies, ideally raw - celery, broccoli, bell pepper, cucumber - every day.
If you can do it without becoming obsessive, step on the scale each morning - there will be fluctuation, but it will help you identify upward trends and act more aggressively before 5# turns into 10#. It's also feedback on whether your current eating and exercise routine is effective or not.
Allow yourself to be hungry for a period of time each day. It will get you back in touch with what true hunger feels like. And if you're getting that light-headed, need carbs now type of hunger, dial the sugar way back and try working on becoming fat-adapted. That will allow you to go longer between meals/snacks, and reduce cravings. When you are trying to decide if you're hungry and want to eat a certain thing, ask yourself if you're hungry enough to eat some less-than-enticing item, like a can of green beans, or a plain piece of fish or something. If the answer is no, you're probably more bored or experiencing cravings, rather than hungry. On weekends, I'll often eat a big breakfast around 11, and then eat dinner, so total calories stay lower than if I had 2 smaller meals plus snacks. And it saves time on food prep, eating and cleanup, and I'm eating at the times when I'm honestly hungry.
Focus on food quality, and you'll get that "cha-ching" feeling when you're eating proper amounts of the proper foods, and feel the opposite when faced with the idea of eating crap.
