Nutreek — Self-hosted weekly nutrition planner

What it is

Nutreek is a self-hosted web app for managing your weekly nutrition plan. You build a week of meals from ingredients and recipes, and it computes the macros — calories, protein, carbohydrates and fat — per meal, per day and per week, with adherence bars against your targets. Ingredient data comes from a local OpenFoodFacts index (full-text search in under 50 ms, offline), so lookups stay fast and private.

It runs either natively as a single Go binary, with no external dependencies, or as one Docker container — SQLite is embedded, so there is no separate database service to operate.

Nutreek weekly dashboard with meals, per-day and per-week macros, adherence bars and inline hydration — The weekly dashboard: meals, macros per day and week, and hydration at a glance.

Features

Weekly plans: A weekly calendar with macros per meal, day and week, cheat meals, and one-click copy from the previous week.
Ingredients: Local full-text search over OpenFoodFacts (offline), barcode and URL import, and a reconciliation job that keeps local entries in sync.
Recipes and templates: Build recipes from ingredients, import them automatically from a URL (schema.org/Recipe), and save reusable weekly templates you can apply in one click.
Auto plan generator: A greedy planner builds a whole week from meal variants to hit your macro targets — the nutritionist-plan workflow, automated.
Adaptive TDEE: Estimates your real energy needs from your weight and intake trend, and suggests target updates automatically.
Weight, hydration, workouts: Daily weight and hydration tracking with trend charts, plus a workout log with calories burned and a weekly dashboard.
Coach mode: A plan library, client assignment, frozen plan history and a coach dashboard for managing multiple people.
Shopping list and REST API: Generate a shopping list from the selected week, and drive everything from a bearer-token REST API (v1).
