Be it at home or in office, it is recommended to meditate on a relatively empty stomach. The reason to meditate before a meal is simple – you might doze off while meditating after a meal.
When you are hungry, the hunger cramps may keep you from meditating. In fact, your mind may even keep thinking about food the whole time! It is advisable to meditate two hours after a meal.
Keep in mind: Do not force yourself to meditate when you are very hungry.
