Willpower fades by evening, especially after a workout. Members who eat consistently well aren't relying on discipline in the moment — they've already decided what they're eating before hunger and fatigue make the decision for them.
Batch a base, not a whole week
Cooking a protein source and a starch in bulk, then mixing them differently through the week, is more sustainable than committing to seven identical meals — variety matters for actually sticking with it.
Prep removes the worst decision point
The moment right after a workout, tired and hungry, is when the least healthy option usually wins if nothing is ready. A prepped meal removes that decision entirely.
