Digestion works best when the body is upright. According to Popular Science, gravity helps move food through the system, whether you are sitting or standing.
Problems mainly arise if you lie down during or right after a meal. In that position, stomach acid can more easily travel upward and cause discomfort such as heartburn.
It also takes several hours for the body to process a meal, which is why eating right before bedtime is not recommended.
Pace matters most
What matters most is not whether you stand or sit, but how quickly you eat.

According to Popular Science, eating too quickly can lead to bloating, discomfort, and consuming more than you actually need.
When the pace is fast, you often chew too little and swallow more air.
At the same time, the body does not have enough time to register fullness, as these signals typically arrive after about 20 minutes.
A slower pace supports better digestion and makes it easier to notice when you are full.

Calm in the body
The body needs calm in order to digest food properly. According to Popular Science, rapid movements or intense activity after a meal can disrupt the process.
Blood is needed for digestion, and if it is instead directed to the muscles, it may cause discomfort. Light activity, such as a short walk, is fine.
Eating while standing is not a problem, but what matters is taking your time and allowing the body to work at ease.
