Don’t ask: “What am I allowed to eat?”
Ask nutritionOS: “What should I cook today – and how do I make it really good?”
or
“I still have X kcal left. What will actually satisfy me?” 🙂
What it is
- A persistent nutrition & cooking system: food is handled as state in files.
- It calculates calories & macros cleanly, logs your history, and builds meals from what’s actually there (your pantry).
- No server. No app. No points. No moralizing.
What you get
- You stop explaining your diet every day: goals, rules, preferences and pantry stay known.
- You cook more often because decisions get easier: pantry → meal instead of vague “ideas”.
- A “bad day” isn’t a failure: nutrition stays connected over time.
What it helps with
Weight loss: sustainable deficit without hunger drama
Muscle gain: protein & energy planned without turning food into a full-time job
Daily life: “What do I eat today?” becomes a simple system question
Constraints: vegetarian/vegan, intolerances, reflux days, low-energy days
Learning to cook: timing, heat, order – restaurant logic on the side
How it works
- You define goals, rules and (optionally) baseline data.
- You set up your pantry: what’s really there – including nutrition values.
- nutritionOS designs meals, scales and balances them, and keeps everything as a continuous log.
- Later you don’t ask “What was that again?”, but: “What actually worked – and why?”
nutritionOS is not a diet app. It’s a system that remembers.

Optional:
If you want to skip pantry setup, you can start with presets – preconfigured starting points (e.g. gourmet pantry, date night, muscle gain, or ASF/protein/dairy expansions).
Note: Presets are paid convenience. nutritionOS itself is fully usable for private, non-commercial use at no cost.
