How serious of an athlete are you? Professional? College level?
I am currently a recreational athlete participating in crossfit and olympic weightlifting, usually training around 2 hours a day. I am also 46 days into Exodus 90, a spiritual formation program that requires fasting every Wednesday and Friday for 90 days, and having no more than 3 meals a day on all the other days (no snacking).
Two days ago I also maxed out my 5RM back squat with a new personal best.
You may be much more advanced than me, or participate in a different sport, but I would say it’s possible to fast multiple times a week and still improve your athletic performance, at least with weightlifting. Try it out a little, like skipping breakfast or lunch once a week and spend the time in prayer, or cut out all the snacking between breakfast lunch and dinner and offer up the hunger to God.
Not gonna lie, back in Jauary I fell sick after training pretty hard after a serious fasting day, so I’m more careful about that now!
If you want to excel in your athletic life, I encourage you to reflect on the words of St. Paul, because fasting is the same as training, and excelling in the spiritual life is of greater value:
1 Tim 4:8 For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come…
1 Cor 9:25 All athletes are disciplined in their training. They do it to win a prize that will fade away, but we do it for an eternal prize.
Pax, and good luck!
