The central message I extracted from the text is, eating is sacred and being satisfied is a key part of the process. In Deuteronomy chapter 8, Hashem describes the land into which He will bring the Jewish people, a land full of bounty. He then declares, ואכלת ושבעת וברכת את יי אלהך על הארץ הטבה, "...and you shall eat, and you shall be satisfied, and you shall bless your G-d for the good earth".
For me, this was a revolutionary concept...the idea that Hashem wants me to eat to the point of satisfaction. Eating, in my world, was an act of necessity. I ate prescribed foods at prescribed times, often regardless of hunger or fullness. Satisfaction was not even on my radar. I considered it a luxury and an indulgence to take pleasure in eating, to give myself more than the bare minimum--and if there was one thing I refused to do, it was self-indulge. But when I read that the Torah actually commands that we be satisfied, I was forced to examine the act of eating from a new perspective.
Food is what sustains us. Without it, no matter how pure our intentions or how righteous we are, we will die. Our hunger for food, rather than being a weakness, is actually Hashem's gift to us--it signals to us that we need to nourish ourselves, to fuel our bodies and care for them. And, allowing ourselves to experience satisfaction is part of the beauty of the act of eating. If eating truly is a holy act, it follows that it should also be pleasurable. Hashem has provided us with such plentitude. I like to think that, just as a parent finds joy in watching his or her child take pleasure in life, Hashem also delights in watching His children satisfy themselves with the food He has provided.
For me, this outlook on eating has changed the way I approach food. Now, before I put the food into my mouth, I spend a few seconds focusing on it in my hand or at the end of my fork, and I say the bracha for that food. I do my best to eat to the point of satisfaction (although to be fair, this sometimes still seems like a work in progress!)...and when I am done, I feel grateful to Hashem for having given me the nourishment I need, and I express this thanks through a blessing. Eating will, in all honesty, probably never be my favorite activity. But now, at least, I consider it a meaningful, sacred potential source of pleasure which Hashem wants me to experience.
