Is fasting during Ramadan considered to be chukat hagoyim? I have been fasting 23 hours a day for almost a year now for weight loss purposes. I know not to do this during Shabbat, chagim, and Rosh Chodesh but was wondering whether it is problematic during Ramadan? Should I davka shift my hour of eating to a time during the day during Ramadan to avoid mirat ayin and the like? Also, would it be appropriate to try to elevate this weight loss method into further kedusha by not drinking either on Mondays and Thursdays and turning this into a voluntary fast?
