All adults between the ages of 21 and 60 are bound to fast on all the weekdays of Lent, beginning with Ash Wednesday and concluding on Holy Saturday, unless excused due to a health issue. If you are in doubt as to whether or not you are excused, please consult a priest. The Fast means there is no eating between meals, and only one full meal is allowed. Two smaller, meatless meals are permitted, as long as the combined amount of food consumed would not equal or exceed what is taken at a normal main meal.
