The Core Framework
Cook in components, not recipes: 2 proteins, 2 carbs, 2 vegetables. Mix and match all week instead of eating one boring meal five times.
None of this requires perfection. Hitting your protein and calorie targets six days out of seven, week after week, outperforms flawless weeks that end in burnout.
The Two-Hour Flow
Oven roasts chicken thighs and potatoes while rice cooks and ground beef browns. Parallel cooking is the whole trick.
Track your intake for at least one honest week before deciding anything is not working. Most stalled progress traces back to intake being different from what we assume.
Portion by Goal
Bulking: bigger carb scoops. Cutting: bigger vegetable piles. Protein portions stay constant either way.
Whole foods should carry the load here; supplements exist to patch specific, identified gaps — not to replace meals.
Storage Rules
Four days refrigerated, rest frozen. Glass containers reheat better and survive years of use.
Adjust based on results, not feelings: weigh-ins trending the wrong way for two weeks is data, one heavy morning after a salty dinner is noise.
The Backup Shelf
Keep canned tuna, Greek yogurt, eggs, and whey for the inevitable day the prepped food runs out. The plan that survives failure days wins.
If you have a medical condition, a history of disordered eating, or take medication, run any significant diet change past a healthcare professional first.
