Nutrition coaching software that clients will actually log

Clients do not fail nutrition because the TDEE formula was wrong. They fail because logging feels like a second job. Software that asks for barcodes at dinner will lose to a sentence they can type.

Targets first

Tarna's nutrition desk uses Mifflin-St Jeor for TDEE, then macros you can assign to the client. Cut and maintain starter days ship in the library. You can add studio foods the catalog does not have.

Logs in ordinary words

The client writes what they ate. You read it. No screenshot dump. Searchable catalog when they want precision, plain language when they do not.

Meals as a plan, not a PDF

Drop a meal CSV onto Nutrition, then Plans. Library cards can assign. The week and the food live next to each other so a cut phase is not a separate product.

Questions

Does Tarna replace MyFitnessPal?
For coaching, yes — the log sits next to the program. Clients who love a public food database can keep it.
