Plan meals and build a grocery list with Claude

They used Claude to turn body stats into meal targets, plan a week of meals, and start a grocery cart, though ordering needed supervision.

What they did
They started on Claude for iPhone by entering their weight, height, activity level, and target weight. Claude turned that into macro targets, asked follow-up questions, then drafted a week of meals with macros and portions for each one. They moved the plan into Excel for shopping, then switched to Claude on Mac because the phone app did not give full MCP support. From there, they let Claude try to shop at H-E-B using recent orders and live site access while they stepped in whenever it got stuck or made poor choices.
How it went
The meal plan and grocery list were successful. Cart building only partly worked: Claude could move around H-E-B and add some items, but it often chose the wrong products, froze on pages, and needed repeated nudges. They planned to keep using it through the list stage, not for full checkout.
Tips
This works better when you stop at planning and list creation, then review every cart item closely. If you want browser control, the Mac app was more capable than iOS in this case.

I want you to help me plan groceries and meals for [number] days for [number] people. Ask me any follow-up questions you need about my goal weight, height, activity level, diet style, budget, dislikes, and kitchen setup. Then calculate macro targets, propose a full week of meals with portions and macros, and make one consolidated grocery list. If I want you to place items in my cart at [store name], use my recent purchases and the store site to do it, but stop and ask for my approval before you change quantities, replace items, or complete anything irreversible like checkout or payment.
