Does anyone NOT count calories? How do you figure out how much of something to eat?

I've lost about 50 pounds and have been in maintenance for 17 months. I stopped counting calories last summer. Logging and weighing got boring, and redundant, because by using MFP for 18 months I had already learnt how to eat - what kinds of foods works for me, what proper portions looks like, what hungry and full feels like. I had also started a spreadsheet meal plan/food log; the original purpose was to eat myself out of the fridge before a vacation, but I continued to use it, as it was easier and quicker to plan meals there than in the food diary and I could see several days at one glance. I created color coded "slots" for fruits, vegetables and nuts. Experimenting with number of meals, I could see a structure starting to form - I noticed I liked breakfast to be either this or that, same with lunch, plus a couple of additional options; dinner is just meat/fish+starch+vegetables or soup/casserole; evening meal is when I prefer to calm down with nuts and/or cheese. I eat quite similar from day to day. After I started weekly dinner themes, I rotate through all my dinners so that I get en even better rythm and balance.

I still weigh calorie dense and uncountable foods like milk, sandwich spread, rice, pasta, peanut butter, nuts. For planning purposes, I also weigh vegetables that I chop, and things like frozen peas and yogurt. Foods that come prepackaged, either from the factory (portioned items) or from nature (apples, pork chops, potatoes) - I'll just pick one (or some) that looks the right size. I don't eat lots of "convenience" foods; most is made from scratch - ordinary foods, nothing fancy, but tasty and easy. This is a plan I want to stick to.

I know that if I stick to this plan, I will maintain my weight - or, actually, slowly lose, but I'll have "treats" now and then, and the size and frequency of those push my weight upwards. I weigh every day, and when I approach the top of my set range, I cut back on the treats. That makes my weight go back down again. It's fascinating to be able to regulate my weight without counting calories. Sometimes all those years of struggling with food and being overweight or afraid of gaining weight, feels like a just bad dream. (No, not really I've worked hard for this.)

I would also vote for the No S Diet - it was one of my inspirations and I use some of the principles, eating meals (but four instead of three) and reserving snacks and sweets for Special days. Mostly I think if my diet was more "junky", I'd have to track.

You always have Rosemary Conley's portion pots for colorful portion control without shelling out money to BB.
"Precise portion" plates etc following the "plate model".
Some of these look nice but I prefer to either eyeball or weigh.

IMO "intuitive eating" has become the holy grail. I'm ambivalent, to be honest. Lots of people can't eat properly without being mindful/aware. These terms are a little fuzzy, and are both opposites and the same. The trick, I think, is to learn what your body really needs, not just how much you can stuff into your stomach. I started with the hunger scale, and bloggers like Isabel Foxen Duke has taught me a lot.
