Food logging

The fastest log is the one you actually keep. Cafeity gives four ways to record a meal — a photo, a search, a barcode or a quick number — and then does what a calorie counter will not: puts the meal on the same timeline as your dose and your symptoms.

The short answer

Cafeity logs food four ways: a photo of the plate, analysed by AI; a search of a database built on USDA FoodData Central and Open Food Facts; a barcode scan; or quick-add of just protein or calories.1 It counts calories, protein, carbohydrate, fat and fibre, leads with protein, fibre and water, never colours food red, and never sets an energy target below 1,200 kcal. AI photo logging has a free allowance; unlimited use is part of Cafeity Pro.

Protein, fibre and water first

On a smaller appetite the risk is eating too little of what matters, so the food log leads with protein, fibre and water rather than with a calorie budget. The reference figures — protein at 1.4 g per kg, water at 33 ml per kg, fibre at 25 g (30 g for men) — are derived in the open on the calculators. The 2025 joint advisory for people on GLP-1 medicines makes nutrient-dense food and adequate protein its first priorities.2

No judgement built in

There are no red foods, no "bad day" banners and no leaderboards. Calories are shown as context. Energy targets are floored at 1,200 kcal, and goal weights at a BMI of 18.5, because an app that pushes intake lower on a medicine that already suppresses appetite is doing harm.

Why the dose and the meal belong together

A food log in a separate app cannot see that your low-protein days cluster after injections, or that a heavy meal preceded the worst nausea of the week. In Cafeity they are on one timeline, which is what makes the daily note and the Visit Summary possible.

Common questions

How accurate is photo food logging?
It is an estimate. You can correct foods and portions before saving, and for packaged food a barcode is more accurate.
Where does the food data come from?
The searchable database is built on USDA FoodData Central and Open Food Facts; the licences page lists the attributions.1
Does Cafeity send my food to Apple Health?
If you connect Apple Health, it writes the energy, protein, carbohydrate, fat, fibre and water you enter. AI-estimated values are never written to Health.
