Milanesa:
I know that there's a limit on how many calories one can consume before they stop being absorbed
But does this apply in a smaller time frame? Like, 2k in one sitting might be too much?
There isn’t a strict “shut-off” point where your body just stops absorbing calories. If you throw down 2,000 calories in one sitting, you’ll digest almost all of it, it just takes longer. Your stomach slows things down, and the food can sit there for hours while enzymes and bile break it down bit by bit.
Now, when it comes to speed, and I studied it for my own accord: on average, the small intestine can absorb somewhere around 100-150 grams of carbs per hour, 20-30 grams of protein per hour, and maybe 10-20 grams of fat per hour. That’s roughly 600-800 calories max absorbed each hour. If you eat way more than that at once, your body doesn’t throw it away, it just spreads digestion out over several hours. That’s why a huge meal feels heavy and can take all day to fully process. In the end, unless you hit the extreme of making yourself sick, most of those calories are still getting stored, often as fat
