Is fasting from food ok during menstruation?

Answer 1

I have fasted safely during the menstruation. In fact, a new study shows that fasting prior to the menstruation or at the very least elimination of all acidic foods e.g. meat, sugar, tea, coffee, soda/pop, and processed foods and starches would eliminate pms.

I was initially concerned, but I did not feel weaker or anything. If you are concerned, drink green tea with honey and lemon, that will give you sufficient energy.
