Shop from recipes, not from a generic checklist
Choose the meals first and combine repeated ingredients across recipes. Check your cupboards, fridge and freezer before adding anything to the basket. If two recipes need leafy greens, buy an amount you can use while they are fresh rather than duplicating both entries.
Use flexible categories
A practical list may include vegetables, eggs or other proteins, dairy or alternatives if you use them, oils, herbs and pantry staples. Your choices depend on your eating pattern, budget, allergies and preferences. “Lower-carb” does not mean one fixed list for everyone; a medically prescribed ketogenic diet has different requirements.
Check labels and quantities
Read the ingredient label for allergens and check the serving size if you rely on nutrition information. Estimate quantities from the number of servings in each recipe, then adjust for leftovers. Group the final list by store aisle or by what spoils first; this makes shopping faster and can reduce forgotten ingredients.
Keep it realistic
Include a quick fallback meal for a busy evening and avoid buying unfamiliar ingredients for every dish. If a recipe needs a hard-to-find item, choose another recipe or a suitable substitute you know works for you. Green Plan collects ingredients from a generated menu into a list you can check off, but you remain responsible for verifying amounts and product labels.
