How Food Loops works
30 articles covering every feature, the math behind your targets, and exactly what happens to your data.
Getting started
A food tracker that logs meals from a photo, a barcode or a plain sentence, and keeps your data on your phone.
What to do on day one, and why the first week of logging matters more than any single day.
Home, Diary, Foods and Plan — what each one is for and when you'll use it.
Logging food
Search, AI Scan, barcode, describe, or manual entry — and which one to reach for.
How barcode lookups work, which databases they use, and why they involve no AI at all.
Log food by typing or talking, in the words you'd use with a person.
Save meals you eat repeatedly so logging them again takes one tap.
Your plan
Mifflin-St Jeor for BMR, an activity multiplier for TDEE, then an offset for your goal.
Why protein is anchored to goal weight, and how the rest of your calories get split.
What a sustainable weekly rate looks like, and why it depends on where you're starting.
What BMI can and can't tell you, and why it's off by default.
Food scores
How filling a food is per calorie, scored 0–100 from protein, fiber, energy density and palatability.
The four-level food processing classification, from unprocessed to ultra-processed.
Tracking
How the trend line and its confidence band are fitted from your weigh-ins.

Personalized analysis of your eating patterns, and the three-day minimum behind it.
Photograph a restaurant menu and get a recommendation that fits your goal.
Turn a photo of your fridge into a plan for the next few days.
What gets sent, what doesn't, and why barcode scans never touch a model.
Health and device
Overlay CGM glucose data on your meals to see which foods spike you. iOS only.
Every toggle, what it reads, and what it writes back.
Home screen widgets and the in-app widget row, and how to reorder them.
Weight check-ins and daily tracking nudges, on the schedule you pick.
Privacy and data
Everything local, no account, and exactly which requests leave your phone.
Back everything up to a file, restore it on a new phone, or wipe it entirely.
Plans
What you get without paying, what Pro adds, and what it costs.
Legal
The limits of what this app is, in plain terms: it is not medical advice.
