Is it permissible for someone who vowed to fast on Mondays and Thursdays to change their intention to fast on alternate days (one day on, one day off), knowing that this would lead to not fulfilling their original vow?

If a fasting person transitions from fasting on Mondays and Thursdays to fasting on alternate days (fasting one day and breaking fast the next), then he has transitioned to what is better, and this is permissible. There is no harm in this, even if it results in him no longer fasting on Mondays or Thursdays, because fasting on alternate days is the best form of fasting.
