Nutrition that adapts to real life

Tracking food is tedious, and most plans collapse the first time you eat out, travel or have a bad week. The information isn't the problem — the friction is. DietGPT removes it by letting you describe your meal in a sentence and getting a sensible estimate back instantly.

Your calorie and macro targets come from a transparent, deterministic engine — the Mifflin-St Jeor equation plus an activity factor and a goal-based adjustment with safety floors. The conversational layer on top helps you apply those numbers to whatever's actually in front of you.

Nothing about your numbers is a black box. You can see every calculation on our free calculators and adjust any estimate DietGPT makes.

We don't promise a specific weight by a specific date, recommend crash deficits, or replace medical care. If you have a health condition, are pregnant, or have a history of disordered eating, please work with a qualified professional.
