Gluttony and muscle-building: what Scripture and Fathers say

The post examines whether consuming large amounts of food to build muscle constitutes gluttony. The author, a certified personal trainer and catechumen in the Greek Orthodox Church named Tim, references Scripture and St. John Cassian. Cassian identifies three forms of gluttony: eating before the proper time, eating until stuffed, and craving delicacies.

The author notes that eating enough to fuel work is not listed among them. He cites the angel feeding Elijah twice because the journey was too great (1 Kings 19:7) and Proverbs 25:16: "Eat so much as is sufficient for thee," adding that for a man training hard, sufficient is more. Paul's analogy of the athlete in 1 Corinthians 9:25 ("Every man that striveth for the mastery is temperate in all things") is interpreted to mean a structured meal plan is temperance.

The post then lists when eating becomes gluttony: using "bulking" as an excuse for junk food, eating out of boredom or emotion, constantly thinking about food, and lacking thanks or restraint. When it is not gluttony: planned, measured portions; eating for strength, not pleasure alone; received with thanksgiving (1 Timothy 4:4-5); and done for God's glory (1 Corinthians 10:31).

The author advises consulting one's priest about personal situations and invites followers for more content on Orthodox fasting, training, and fitness. The discussion centers on applying patristic teaching on gluttony to modern fitness goals, distinguishing between disciplined nourishment and excess driven by passion.
