We've all been taught growing up not to waste food, for there are so many who don't have enough. And while wasting food does make me feel extremely uncomfortable and guilty, I have also learnt to appreciate what I have. I had gotten into the bad habit of eating my meals in front of the TV, especially after spending so much time at home with nothing to do. But since the past couple of months or so, I have stopped doing that. No TV, no phones, no screens while eating. Even if I am eating something that I don't like I sit quietly at the table and savour every bite. Food is what nourishes the body ( and sometimes the soul when it comes to desserts :) ) and it should get the respect it deserves.
Try doing that - try tasting every bite thoroughly, chewing it completely, feel the texture and then imagine it giving energy and nourishment to your body. Trust me, it will feel better than quickly gulping down a meal with eyes glues to your screen.
