Is meat the ideal food? If we are synthesizing food, shouldn't we be creating the ideal "super food"? I'm shocked that the equivalent of a Jetsons style vending machine that puts out a small bite with all the right nutrients doesn't exist. But I guess that's what "Cliff" bars etc are, right? -surely we can do better though. I'm thinking of the gum from Willy Wonka that replicates a 4 course meal. -3D print that
Theoretically, if you had a portion of this super-food, which was the size of a piece of gum, yet had enough nutrients packed into it to sustain you for a full day. Similar to Willy Wonka's gum. Would you still feel hunger? I have a feeling that even with the perfect energy and nutrients in a tiny portion, still lacks the volume required to fill your stomach. Still an good point/idea with amazing potential.
I think the stomach naturally will shrink over time and change "it's expectations". At first you would feel the hunger but eventually, you'd establish a "new normal". This is just a guess based on some fasting I've done.
