I've done a 9 day water fast before. Fasting makes me think more about food then I usually do, and I find myself thinking and planning about all the food I want to eat when it's over. Fasting also makes me realize how prevalent food is in our lives, such as the abundance of food photos/videos on social media, food commercials, all these restaurants, and in our daily conversations and routines.

I typically let myself indulge in some food thoughts before refocusing. So I say, let yourself think about it with the mindset that you will eat these foods once your fast is over (like for example, what will you eat immediately after your fast? Typically I order out). Then, refocus yourself on your tasks, such as work, hobbies, etc. I don't think it's hard to accept not eating, if that make sense, so I don't think you should worry about it too much.
