Tips on how to stop mindless eating?

One thing I learned about myself and mindless eating is that often I mistake thirst for hunger. I like green tea so when I "feel" hungry when I think I shouldn't be, I"ll have a cup of green tea instead of reaching for food first. It seems to work well for me. I also keep almonds or walnuts at my desk and low fat greek yogurt in the fridge at work so there are healthy options for me for those times when I really do need to have a snack.

Agree with (a) logging everything BEFORE you eat it; (b) staying hydrated (drink plenty) - and if all else fails, you might try fasting for a day - pay attention to what actual hunger feels like…and once you break the fast, look for that feeling before you eat.

Keep food out of sight! It's the only thing that works for me.
I used to work on the dining table and found that working on the couch makes me think of food less. Especialy because I'm also farther away from the kitchen (no smells)

Try brushing your teeth. I find that stops me from snacking afterwards because food tastes terrible with a mouth full of toothpaste flavour.

Step 1) get rid of all junky snacks out of your house full stop, even things like cereal so you actually have to prepare food if you want to eat it, easy access food is such an easy trap to fall into.

Step 2) (what works for me) is get some sugar free gum, lollypops, fruity ice lollies (check the cals or make your own) in which are usually only a few calories a pop (these are full of sweeteners though so not technically healthy but this is what helps me) I also have low cal hot chocolate in so I'll have a 40cal mug of that to stop chocolate bar cravings. If you want to chew on something substantial raw veggies like carrots, cucumbers, peppers and celery are okay as you have to eat a shed tonne before they add up to triple figure calories.

Step 3) occupy your hands if you're watching telly, whether it's playing a 3DS, reading the forums on MFP or knitting, alot of eating in front of the tv is just out of boredom or restlessness.

Also don't eat again until 30 mins after dinner so your body can register with your brain that you are no longer hungry, and also make sure you have plenty to drink and have a full drink next to you, sometimes you may just be a little dehydrated rather than actually hungry.

I was (Still am sometimes) a compulsive emotional eater. I have an anxiety disorder and don't like being out in public and the first thing I turn to is munching on something to take my mind off it. If I could just 'not do it' I would, but I haven't figured that out yet. So what I do at work is keep a huge bag of baby carrots on my desk, I can munch on these all day. If I can eat 15 oz of baby carrots, go for it. I don't really like them though, which is kind of important. I also keep things like fresh baby tomatoes (the bitterness makes me not want to eat them) and those are my only two choices. At home is definitely harder since I pass all these lovely little restaurants on the way home. It's pretty normal for me to leave my debit card at home so I don't go out. Once I'm home and I think about the cold I don't really want to leave again.

Learning to not do it is very important, but I had to start by tricking myself. Lol.
