Batch cooking's advantage is mostly in the fixed costs — one shop, one set-up, one clean-down. Cooking twelve portions takes barely longer than cooking four, which is where the hours come back. Food safety puts a real limit on the window. Cooked food keeps three to four days refrigerated, so anything beyond about four days of prep needs freezing rather than chilling, and cooling quickly before refrigerating matters more than most people realise. The calories-per-meal figure assumes an even split, which rarely matches how people eat. Adjusting portions around training or the working day is usually more sustainable than three identical containers.

Frequently asked questions
How many days ahead can I prep?
Three to four days refrigerated for cooked food. Anything beyond that should be frozen rather than chilled, and cooling quickly before refrigerating matters as much as the total time.
Does batch cooking actually save time?
Mostly through fixed costs — one shop, one set-up, one clean-down. The marginal time of extra portions is small, so the saving grows with batch size rather than being proportional.
Should every meal have the same calories?
Rarely how people eat. An even split is the default here, but adjusting portions around training or the working day is usually more sustainable than three identical containers.
How many containers do I need?
One per meal unless you portion two meals to a container. The figure here rounds up, because half a container is not a thing you own.
Does prepping reduce food cost?
Usually, through bulk buying and less waste. The cost per meal here is whatever you enter divided across the meals, so it reflects your prices rather than an assumed national average.
