One of my worst habits is I eat food too quickly - especially when I am hungry or the food is extra delicious. Both my father and brother wolfs down food with much speed too so I guess it runs in the family. I've no doubt it contributes to my chronic stomach acid problems (it remains disappointing that I can't drink coffee), and more importantly I am not taking the time to savor the plate.
Sure saves a lot of time, though.
A mechanism I've gotten into to combat the ingestion haste is to be thankful for the food before commence eating. Not dissimilar to what Christians do in saying grace before a meal, when I give thanks for the food, I give myself a reminder what a blessing it is to have the opportunity to eat the particular meal - no matter how extravagant (or not) it is. In that mindset of gratitude, I find myself deliberately slowing down to enjoy each bite, and it's been highly beneficial.
In concurrence I also acknowledge having the good fortune to not have to rush through a meal: there are no deadlines or work pressures that would otherwise require me to eat fast to return to what I am doing. For sure there are others that don't have such luxury.
Lastly, when I eat slowly, I also end up eating less - those satiation signals after 20 minutes or whatever, which isn't so bad now that I'm on this side of the 30 divide.
