You can fast for a couples of days, without going hypo, but if you take your meds, you may, the body allows itself to do without, as long as you continually drink water, it is not recommended, but your body will respond. If you can eat, then eat! I think I have a higher tolerance towards your situation as it has happened with the wife, with her father! There has to be a type of food in the house or fridge that you can put up with until, you can get back on your diet,
Please don't sit and suffer as it empowers him more!
Maybe I shouldn't judge but you posted!
