From a book called Saintly solutions to lifes common problems -Fr Joseph Esper - this is the prayer at the end of the chapter in gluttony (you may want to get it and read the chapter) Oh I am sure you know but gluttony does not refer only to food. Also as I always suggest Fr Mike Schmidt has some interesting perspectives on youtube. I don’t know if it’s ok to recommend him on here, but he is a Catholic priest and teacher so I guess. (ps forgive any error’s I am a terrible typist)
Here’s the prayer
Lord and Giver of every good gift
help me truly to appreciate all the You have
granted me, including the food I eat each day.
Let me not be gluttonous,
nor displease You by overindulging myself.
May the bread You give me be a source of energy,
health and strength, so that I may fulfil my duties and
do my part in working for the coming of Your kingdom.
Give me a generous spirit in responding to the needs of
the poor, and fulfil the hopes of all who trust in You.
Father, You give us the bread we need each day;
may we render unto You the glory and praise
that are Yours for all eternity. Amen
