Nutrition & Macros

Say what you ate the way you'd tell a friend, and get honest calories and macros against your budget.

Describe what you ate the way you'd tell a friend — "two eggs on toast, a flat white" — and get honest calories and macros against a budget you set together, every day. Nothing to weigh, no barcodes, no app to open: say the meal in passing and it lands on the log with an estimate that says it is one. The board keeps the day's arc against your budget, the macro split, the week day by day, the protein line and which days you logged; the evening close asks once about a meal you skipped mentioning and gives you the day in one line of arithmetic — never a verdict. Set the budget from numbers you already use, or let it work one out and show its method. If you also keep Weight & Body, the budget reads your goal and the close puts the smoothed weight beside your calorie balance.

1 agent, 1 routine, 1 dashboard, 2 records, 2 skills. Installing ends with Meet Fern — a short conversation sets it up, and everything can be retimed or paused after.

The crew

Fern

Keeps honest estimates, and keeps its opinions to itself.

Plain, unhurried, honest about what an estimate is.

What else it installs

"Two eggs on toast and a flat white" — that is the whole interaction.

How it works

The mechanics of this kit, plainly — what runs and when, where the data lands, and what you look at.

  • Evening close runs every day · 9pm and keeps the Nutrition dashboard fresh. Every evening — asks once about a meal you skipped, then the day in one line.
  • What is captured lands in the Food log record, which lives at Data/Food Log in your vault — yours to open, search, and edit like any other file.
  • What is captured lands in the Nutrition targets record, which lives at Data/Nutrition Targets in your vault — yours to open, search, and edit like any other file.
  • The Nutrition dashboard reads from the record and shows, at a glance: macro split, all logged meals · the day's calories · protein that day · carbs that day · fat that day · the week, day by day · meals logged · protein, the last two weeks · what you are aiming at · days you logged · beside the scales · every meal.

The wiring, in one breath: Meal logging writes to Food log · Food log shown by Nutrition · Nutrition kept fresh by Evening close · Evening close run by Fern · Fern holds Target setting · Target setting writes to Nutrition targets.

Getting the most from it

A kit earns its place when it changes what you look at and what you say, not when it is installed. This is the rhythm that makes it pay.

  • Say meals the way you would tell a friend — "two eggs on toast and a flat white" — and let the estimate be an estimate. Consistency beats weighing.
  • Set the budget and macros with Target setting once, with the method shown, or give it the numbers you already work to.
  • Read the day against the budget in the evening, after the close has asked about anything you skipped. The week view is where the pattern is.
  • Correct an estimate when you know better — "that was a large portion" — and Fern learns your portions.
  • Ask Fern for the week in a sentence rather than counting it yourself.

Make it yours

Nothing here is fixed. The pieces are ordinary agents, routines, records and dashboards, so anything you know about shaping those applies. Retire whatever earns nothing.

Things people usually change first

Say any of these in chat, or edit them on the kit’s page in the app.

  • The budget and the macro split — or clearing the budget entirely and just keeping the log.
  • When the evening close arrives, or turning it off and just keeping the board.
  • How much it says back when you log a meal — the estimate and the running total, or the estimate alone.
  • Whether it asks about a missing dinner at all.

Your first run

Installing starts a short setup conversation — not a form. Answer roughly, correct later.

  1. Installing ends with "Meet Fern" — a short conversation, not a form. If you already work to a calorie budget or macro targets, say them and that is the whole setup. Otherwise Fern works out a maintenance estimate from your details and what you want the budget to do — hold where you are, or move gently — and records the figure with its arithmetic beside it. If you keep Weight & Body, it reads your goal from there and never asks twice.
  2. From then on there is nothing to open. Say "two eggs on toast and a flat white" in any conversation and it lands on the log with an estimate that says it is one — about 420, never 417 — and the day's running total against your budget. A figure from a pack or an app beats the estimate every time, and "that was more like 600" corrects the row.
  3. Skip the conversation and the door quietly stays open: until a budget is set, the kit page, the board and Fern's chat keep the offer ready — and the macro rings, the meal count and the meal rail fill from the first meal regardless. The evening close stays silent until the log has its first line.
  4. At nine each evening, on a day you logged, Fern asks once about a meal you skipped mentioning and gives you the day in one line of arithmetic. A day with nothing logged gets no card at all — a day off is a day off, and nothing here has an opinion about it.

Watch the first pass, then tell it what you would have done differently — that correction teaches it more than any setup could.
