TDEE and calorie goals

Total daily energy expenditure and calorie deficit/surplus targets using the standard energy-balance model.

Frequently asked questions

Is the food database licensed or scraped?

Ingested from USDA FoodData Central, a public-domain government dataset — no scraping, no licensing risk.

Does this require a live third-party API key?

No — the food data lives in our own database, so there's no upstream key or rate limit to manage.

Can I search foods by name?

Yes, via /food-search and related endpoints in the food namespace, which shares the same owned dataset.
