From the age of 14, people are obliged to ABSTAIN: this obligation prohibits the eating of meat, but not eggs, milk products or condiments of any kind, even though made from animal fat.
The days of ABSTINENCE (no meat) are all the Fridays in Lent in addition to Ash Wednesday and Good Friday. No dispensations are granted on these solemn days except for reason of sickness or those provided in canon law below.
The pastor of a parish has the faculty to give a dispensation to individual parishioners in his parish and the Diocesan Bishop alone has the authority to dispense groups of Catholics but only for a serious reason.
