I don't know if these are tricks or not, but I do have a process that seems to work pretty well.

I am very consistent in my meals. I eat the same breakfast every day. My dinner usually consists of 5 oz of meat of some sort (weighed, even after 10-11 years of WW!), 4 oz baked potato (again, weighed), and a bunch of steamed/baked/roasted veggies (mostly broccoli, red and yellow peppers, onion) that fill up the rest of my plate. For lunch, I have half of whatever I had for dinner the night before. There are some times when I don't have meals that really fit with this, but I try to keep those meals limited.

That level of consistency is important and helpful for me because I know that that amount of food is enough to satisfy me at a given meal, and that I am not starving before the next meal.

It is a bit boring, but it keeps me from playing a game with myself and rationalizing that I need more food at a meal because one-serving won't be satisfying, or that I "deserve" a snack because I didn't have enough at a meal, etc.

A second "trick" is that lately I have said I will not drink alcohol or have snacks during the week. Period. The end. Having made a more definitive statement helps me because there is a definitive plan, rather than something less clear (like, "I will drink less and have fewer snacks during the week.").

A third "trick" is that I have given myself a replacement for post-dinner drinks and snacks. I plan to make a cup of hot tea every night around 9 pm (my typical snack time). That way I have something to look forward to and something that will occupy the same senses (taste and smell) that a snack would. And of course, I avoid extra calories that way.

I hope these are helpful.

Delay is a valuable tool and greatly underrated. I plan regular meals and regular snack. I try to make everything appealing in some way. It has to be worth waiting for. I'm not going to be able to wait all afternoon for a few baby carrots. But I could get past the office vending machines to get home for my smoothie snack. After I made it to the car I was committed to waiting.

And speaking of that smoothie- reframing. Remember the WW tools for living? Reframing was one. I don't recall how they defined it. But in my mind that WW smoothie mix with some blueberries and crushed I was a milkshake. Just like a WW English muffin, some low fat mozzarella and dab of tomato sauce was pizza.

Not really tricks but I do have a conversation with myself. I.e. "You ate a complete meal 2 hours ago. You are not hungry, so just go find something else to do". It's way easier for me to just say 'no'. If I have some, it's way tougher to say 'no more'.
