I also have difficulty with fasting from food, because I’m always pregnant, nursing, or both. Even if you need to eat a certain amount for health reasons, you can still “fast” by choosing to avoid certain meals you really like and substituting something that is good for you but less favored. Maybe a meal you don’t really like, but your spouse or children do!
I’ll also give my family all the meat in a meal, if they want it, and just eat the rice and vegetables myself.
Thanks for the suggestions TC. That sounds like a good place to start.
