Good effort! I've never really tried to fast more than a day, though a few times when I was sick I went a long time without eating. I did OMAD or one meal a day for 3 years and then eventually felt like I prefer snacking or having a small meal earlier in the day before my big meal.

There's some interesting science behind fasting, and some is concerning.. Some people even die fasting.. It can be dangerous.. What makes you want to try fasting for so long if you don't mind me asking?
