Macro-Friendly Shopping List Builder

First, the calculator pulls per-serving nutrition from its built-in library for every selected food (protein, carbs, fat, and calories). It then scales your macro targets to your planned number of servings, allocates the required grams evenly across the foods you selected within each category, and sums everything to get achieved totals. Finally, it generates a practical shopping list quantity per item and reports gaps (over/under) and a macro fit status.

This tool assumes the nutrition library values are close enough and that your servings mapping matches how you label meals (per day vs per serving). It also rounds quantities to user-friendly units, which can create small deviations from exact grams. The “fat style” option matters: “fixed” prioritizes hitting fat first (then fills calories with protein/carbs), while “balanced” aims for a more proportionate match across all macros.

Make sure you select at least one food in each category (protein, carbs, fats)—missing a category will prevent the list from properly covering macros. Also double-check your inputs: the calculator treats macro targets as corresponding to the servings you choose, so using daily targets with a small plan (or vice versa) can skew results. If a target is set to 0 for a macro (like fat), the shopping list may end up forcing fats to 0 and you should expect deviations if you still select fat foods.
