Tutorial: Importing Nutrition

Your strap tells you what you spent — calories out, strain, recovery. Nutrition CSV import lets you put what you took in right next to it. Export a simple daily CSV from your food tracker, import it into NOOP, and your calories-in sits beside your calories-out in Explore and Compare — so you can finally see how the two move together over weeks.

Like everything in NOOP, it's a local file you import once. Nothing is uploaded, and you don't need an account anywhere.

What you get

Once imported, your nutrition becomes a first-class set of metrics:

  • Calories in lines up against calories out (active + basal energy) in Explore and Compare.
  • Macros — protein, carbohydrate, fat — become their own series you can plot and correlate.
  • The correlation tools can then answer questions like: do higher-carb days track with better next-day recovery? or does an energy surplus show up in my weight trend?

NOOP doesn't judge your diet or set targets — it just makes nutrition another honest signal you can interrogate alongside the rest.

What you'll need

  • A food tracker that exports CSV — Cronometer and MacroFactor are the tested ones, and any tracker (or a spreadsheet you keep by hand) works as long as the columns match the layout below.
  • A daily CSV — one row per day. (Per-entry exports with many rows per day also work; NOOP totals them per day on import.)
  • NOOP on macOS, iOS, or Android.

Part 1: Export a CSV from your tracker

Cronometer

  1. Open Cronometer on the web (cronometer.com — the export lives there, not always in the mobile app).
  2. Go to Settings → Account → Export Data (sometimes under a Data or Export menu).
  3. Choose the Daily Nutrition / Daily Summary export (the per-day totals), pick your date range, and download the .csv.

Cronometer's daily export already has a Date column and totals for Energy (kcal), Protein (g), Carbs (g), and Fat (g) — exactly what NOOP needs.

MacroFactor

  1. Open MacroFactor.
  2. Go to Settings / Profile → Export Data (look for a Data export option).
  3. Export your daily log as .csv and save it somewhere you can reach from NOOP (Downloads, Files, iCloud Drive).

MacroFactor's export includes a date and daily calorie and macro totals, which map straight onto NOOP's columns.

Any other tracker (or a spreadsheet)

If your tracker can output a CSV — or you keep your own — just make sure it has a date column and a calories column, with optional macro columns. See the accepted headers next.

Part 2: The accepted columns

NOOP is flexible about header names so it works with different trackers. It needs a date and calories; macros are optional but recommended.

Field Accepted column headers (case-insensitive) Required?
Date Date, Day, Timestamp Yes
Calories in Calories, Energy (kcal), Energy, kcal, Calories (kcal) Yes
Protein Protein, Protein (g) Optional
Carbohydrate Carbs, Carbohydrate, Carbs (g), Carbohydrate (g) Optional
Fat Fat, Fat (g), Total Fat Optional

Notes:

  • Dates should be recognisable calendar dates — 2026-06-12 (ISO) is safest; common DD/MM/YYYY and MM/DD/YYYY styles are handled too. ISO removes any day/month ambiguity, so prefer it if your tracker offers it.
  • Multiple rows for the same day (per-meal or per-entry exports) are summed into a daily total automatically.
  • Missing macro columns are fine — you'll get calories-in without the macro series.
  • Blank cells are treated as no data for that day, not zero.

A minimal valid CSV

Date,Energy (kcal),Protein (g),Carbs (g),Fat (g)
2026-06-10,2180,142,201,78
2026-06-11,2460,138,255,86
2026-06-12,1990,150,160,71

Even this works (calories only):

Date,Calories
2026-06-10,2180
2026-06-11,2460

Part 3: Import into NOOP

The nutrition import lives in Data Sources, the same hub you use for WHOOP and Apple Health.

macOS / iOS

  1. Open NOOP and go to Data Sources.
  2. Find the Nutrition (CSV) card.
  3. Click / tap Choose CSV… and pick the file you exported.
  4. NOOP reads it on-device and totals each day. When it's done you'll see a confirmation — days imported and the date span covered.

Android

  1. Open NOOP and go to Data Sources.
  2. Tap Choose CSV under the Nutrition card.
  3. Select your exported .csv.
  4. NOOP ingests and stores it locally; a count of days appears when it finishes.

Re-importing: importing an updated CSV is safe — NOOP keys nutrition by day, so re-importing overwrites a day's totals rather than stacking duplicates. Export fresh from your tracker whenever you want to top up, and re-import.

Part 4: See calories-in next to calories-out

This is the payoff. Your nutrition is now a set of metrics like any other.

In Explore

  1. Open Explore.
  2. Under the Activity / nutrition grouping, pick Calories In (or a macro).
  3. You get the full detail dossier — trend chart, average/min/max, and a "What correlates" scan that compares calories-in against every other metric over the window.

In Compare

  1. Open Compare.
  2. Add Calories In, then add Active Energy (or Total Calories Out) — and optionally Weight or Recovery.
  3. The normalized overlay puts them on one timeline, and "How They Move Together" gives each pair a plain-English read — e.g. "When calories in rise, weight tends to rise — a moderate positive link."

Worth trying:

  • Calories In vs Calories Out — your energy balance over time, at a glance.
  • Carbs vs next-day Recovery / HRV — does fuelling track with readiness?
  • Calories In vs Weight — does a surplus or deficit show up where you'd expect?

As always, NOOP shows what moves together, not cause and effect — these are prompts for your own judgement, not instructions.

Troubleshooting

"Import failed" or "no rows found". Open the CSV and confirm the first row is the header and that it has a recognisable date column and a calories column (see the accepted headers above). Exports wrapped in extra preamble rows can confuse the parser — delete any rows above the header.

Calories imported, but no macros. Your CSV probably lacks protein/carbs/fat columns, or they're named in a way NOOP doesn't recognise. Rename them to one of the accepted headers (e.g. Protein (g)) and re-import.

Dates look shifted by a few days. Likely a DD/MM vs MM/DD ambiguity. Re-export in ISO format (YYYY-MM-DD) if your tracker offers it — it's unambiguous.

Totals look doubled. You may have imported the same file twice in a way that didn't overwrite, or you have a per-entry export and a daily export of the same period. Stick to one export style; NOOP sums per-day, so don't combine a per-meal file with an already-totalled one for the same dates.

Privacy

  • Local file, local import. Your nutrition CSV is read on-device and stored in NOOP's local database. Nothing is uploaded.
  • No account. NOOP never connects to Cronometer, MacroFactor, or anywhere else — you export the file, you hand it to NOOP.
  • Yours to remove. Clear it by wiping NOOP's local data (see Importing History) or uninstalling.
