I found part 1 to be the least helpful. I don't know if it's because I have some concepts of mindfulness, or maybe I just couldn't identify with the people she was portraying. However parts 2 and on were much more helpful. I really liked the tip of "if you know you want to emotionally eat, do something mindful for 5 minutes, even if it's suck on a hard candy." A lot of my emotional eating is sweets, so a hard candy can give me that little bit of sugar while I also have a chance to examine what emotions are making me want something else. Plus, I can do it anywhere, in the car, at work, at the grocery store, etc (some of the other tips, like imagine getting a full body massage, while I can, and sometimes do use to relax, are a little less practical while I'm also trying to live my life). I think I'm going to have a harder time being more mindful as I eat, even if I'm eating due to real hunger. Just these past few days, I've tried being mindful as I eat, but then I look down and realize, "where's my sandwich that I was mindfully observing?" Whoops.
If you're trying to incorporate mindfulness into your life as a way to reduce stress, depression, anxiety or just feel better in general, I think learning to eat mindfully is a great way to practice mindfulness. It's something you have to do multiple times a day, so there's lots to practice and food gives you lots of ways to be mindful: smell it, see it, touch with your hands, with your lips, with your tongue, how do you feel about this piece of food, what emotions or memories come to mind, how do you feel after you've eaten it etc, etc...
