If you eat standing up, the blood flow in your feet will increase and the blood flow in your stomach will be insufficient, so it is not very beneficial to eat standing up.

If you squat down, there is not enough room in your abdomen, and it will squeeze into your stomach, and eating is just when your stomach needs space, so it is not good to squat down and eat.

According to expert analysis, it's best to sit still when eating, and don't "walk in a hundred steps" immediately after eating. You should rest for half an hour first, and you should also sit, don't lie down, or food may flow back to the esophagus, especially when you are too full. If you want to do strenuous exercise after dinner, you'd better rest for more than an hour. Because blood needs to be dispersed into muscles during exercise, the blood supply to the stomach will be affected, which is not conducive to the digestion and absorption of nutrients after meals.
