You can calculate TDEE and macro splits using offline stdlib calculators that take your weight, height, age, and activity level to compute daily energy expenditure and distribute protein, fat, and carbohydrate targets for cutting or bulking.

Yes, you can search for exercises by muscle group and equipment using the wger exercise database API integration, which allows filtering workouts by category and retrieving detailed exercise information for planning.

You look up food calories and macros by querying the USDA FoodData Central database via JSON-based API calls, using your environment-driven USDA_API_KEY with a DEMO_KEY fallback to retrieve nutritional information.

No, you do not need an API key to use the USDA nutrition tracking features; the system defaults to the DEMO_KEY fallback if a USDA_API_KEY is not provided in your environment variables.

You can compute BMI, TDEE, one-rep max estimates, macro splits, and body fat percentage offline using pure Python stdlib calculators, ensuring deterministic computation without external API dependencies.

Yes, this approach works for planning both workout routines and daily nutrition together by combining wger exercise discovery with USDA food macro lookups and offline calculators for a comprehensive fitness planning workflow.
