This is a very doable technique and you can with practice it so nobody notices, if you happen to be at an important dinner.
Try it and see if you feel more relaxed and are eating more slowly than usual.
Another technique is to set a minimum time to eat a meal or snack. Make it about 30% slower than your normal speed to start off with. You have multiple times a week you can practise this and get better. It really is a practice, not a perfect
I have more slow eating games for you coming up, but start off with these two for now.
