Go to Settings > Kitchen Settings > Macros (Macros module). Each macro row shows Daily Value, Sufix (unit such as g or cal) and four click-to-edit fields:

• Front - how the macro appears on the website: Hide, Show in calories, Show as Primary Information or Show as Sub Information.
• Labels - the same choice for printed labels.
• Round Decimal - number of decimals used everywhere for that macro.
• Color - hex colour of its progress bar in the meal editor.
• Ingredients API (Ingredients API module) - which nutrient from the online ingredient database maps to this macro.

Click a value, change it and press enter to save. Macros hidden on both Front and Labels disappear from the meal editor's macros table and are skipped by the AI recipe/macro-estimation tools.
