I am interested in fasting, particularly during Lent but also throughout the year, in combination with prayer, as a penance. I want to do this in imitation of our Lord and of many great saints, St. Catherine, St. Dominic, etc.
However, I have had issues with food and losing weight in the past. Not serious health issues (no anorexia or anything) but I tend to become focused on that one aspect of myself.
How do I fast without giving in to the temptation to vanity? I thought it was wrong to fast and try to lose weight but a confessor I asked said it was not. I’m not sure.
