fitness-nutrition

To calculate TDEE and macros for a workout plan, use offline Python scripts that compute Total Daily Energy Expenditure and body fat, then derive daily nutritional targets. These calculators require only the standard library to function.

You do not need an API key to look up USDA nutrition data, as the system uses a DEMO_KEY fallback for FoodData Central queries. Providing your own USDA_API_KEY is optional and helps avoid rate limits.

You can build a gym workout routine by muscle group, category, or equipment without authentication. The Skill queries public endpoints of the wger API to retrieve and plan exercises.

The best way to create a weekly fitness and meal plan with macro targets is to combine wger exercise lookups with USDA nutrition data. This generates a unified summary of workouts, meals, and goals for sharing.

The BMI and 1RM calculators work offline using local Python scripts. They compute Body Mass Index and One Rep Max without external API calls, requiring only the Python standard library.
