I know this is impossible, but what if someone magically produced a pill that met all of your nutritional and fluid intake needs for 24 hours? You could take a pill and your body would act normally, except that you wouldn't get hungry or thirsty for a day. You could eat or drink in addition to the pill, but then you'd run the risk of gaining weight. There would be no side effects from the pill and it would meet all of your physical needs perfectly.
You could take a pill one day and eat regularly the next, or mix in any combination, without physical harm.
Would you take the pill or would you prefer to taste and eat your meals? Even if you have to make them? Or would you mix it up with pills some days and meals on others?
Me? I'd live on the pill.
