How many calories should I eat to lose 1 lb per week?
Estimated maintenance calories and a deficit target.
BMR formula, activity multiplier, and weekly deficit arithmetic.
OzzzAI calorie calculator
Ask for calorie math without filling out a rigid form.
Tell Ozzz your goal, stats, activity, and constraints. It computes planning numbers and shows the assumptions so you can revise them.
The first screen stays conversational. The detailed work appears when it matters: inputs, assumptions, formulas, code-backed method, checks, and caveats.

Why conversational
Real calculations rarely fit a single form.
You can start with an incomplete question. Ozzz can calculate from what you gave it, state what it assumed, and let you revise the inputs in the next message.
Audio stays useful on mobile: Ozzz can speak the short answer while the screen keeps the full work available for inspection.
The point is not to hide math inside a chat bubble. The point is to make the calculation inspectable without making you operate a spreadsheet first.
Examples
Questions this page is built for.
Each example is meant to become a transparent calculation, not a model-only guess.
Give me protein and macros for 2,200 calories.
Protein target plus fat and carb ranges.
Body-weight protein assumption and calorie-to-gram conversion.What does this meal cost per serving and how many calories?
Per-serving calories and cost from ingredient quantities.
Unit conversion and ingredient totals divided by servings.Method
The useful parts stay visible.
Ozzz is designed to show the answer, the assumptions, the method, and the caveats. For planning questions, it should make the calculation easier to revise, not harder to trust.
Inputs
Numbers you supplied are preserved as exact facts. Missing variables are called out as assumptions.
Formulas
Standard formulas and component outputs are shown when they help explain the result.
Code-backed work
For serious calculations, Ozzz uses code-backed computation instead of mental arithmetic.
Revision
Ask “what if the APR is lower?” or “change activity to light” and continue from the prior calculation.
Start
Open Ozzz in calculator mode.
Calculator mode starts monolingual, keeps assistant audio on, and turns off practice-language translation by default. You can change settings later.
