Traditional fasting is off the table for me this year. Between chemo and being dangerously underweight last year, drs orders are to eat as much as possible to put on more lbs.
Before cancer I was fasting 1-2x/week and I miss it. Other types of fasting are good, like from buying and social media, but there's a reason abstaining from food was a commonly practiced spiritual discipline in 1st century Judaism and the early church, and it's clear that Jesus expected his disciples would fast after his ascension.
Food is good and necessary for the body, which is also good, but there's something about denying a fleshly appetite for a period of time that I find very meaningful and useful. Like I said, I miss it, hope to start again soon.
So for Lent I've been considering alternatives, haven't really come up with anything. I don't drink alcohol anymore after having most of my liver removed, nor do I smoke or anything like that. The only thing that comes to mind is giving up social media/internet forums, as these take time during my day. So I may do that, even though Lent has already started and here I am on a forum, lol.
