Groceries on a kitchen counter: eggs, yogurt, canned fish, lentils and greens

Most nutrition advice assumes an unlimited grocery budget, a daytime schedule and a kitchen you get to use every evening. Enough Canadians work nights, rotate shifts or shop to a fixed weekly number that the standard advice fails before it starts.

These pages take the constraints as given. Where protein is cheapest per serving in a Canadian supermarket, how to eat through a night shift without the 3 a.m. vending machine, and how to order in a restaurant without treating it as a special occasion that requires atonement. No meal plans to buy and no supplements to sell.

One theme runs through all of them: protein and fibre do most of the work, because they change how full a given number of calories leaves you. That is why the grocery page is organised by cost per serving of protein rather than by food group, and why the shift-work page starts with what to eat before a night rather than what to avoid during it. Rules about timing and windows come last, because they matter least.

Prices on these pages are deliberately described in relative terms. Canadian grocery prices differ across provinces and move faster than any page can be updated, so a specific dollar figure printed here would be wrong within months — what stays true is which shelf the cheap protein is on. If money is the binding constraint, the budget protein guide is the place to start.
