eli5: Do extreme differences in the frequency of eating affect nutritional absorbtion if the total quantity of food is the same?

211 views

For example, let’s say that I typically consume 21,000 calories in a week. If I space that out as evenly as possible, that would be 1,000 calories every 8 hours. If I were to eat 10,500 calories in a single sitting twice during that week, would my body be able to absorb the same number of calories?

It could, but it most likely wouldn’t affect things much for the average person. When you eat, your body senses how much is coming in and what types of nutrients. Then, signals are sent that affect the rest of the intestinal tract. Some of these signals cause your body to move stuff that’s further along more quickly, basically to make more room. In people who have certain medical conditions or who have had surgeries like stomach bypass, these signals can be a little haywire, to the point that things move through so quickly that your body doesn’t have enough time to absorb as much of the nutrients. In those cases, eating smaller amounts can dampen the signals enough so that isn’t a problem.
