Sahni
ChatGPT pluginDaily nutrition targets
Sahni brings the nutrition engine of the Sahni iPhone app into ChatGPT.
Ask for your daily targets and Sahni works out your calories from the Mifflin-St Jeor equation and your activity, then protein, carbohydrate and fat from the Perfect Health Diet for healthy adults (guideline values otherwise), plus fiber, vitamin C, iron, potassium, vitamin B12 and B6. Every target comes with the sources behind it, each linked, and a card with the foods that carry each nutrient.
Safety comes first. Pregnancy, breastfeeding, diabetes, kidney disease and an eating-disorder history keep targets at maintenance, with a note to confirm them with a clinician. Under 18 there is never a calorie deficit, and Sahni does not calculate targets for anyone under 15. Calorie floors and a ceiling always hold, and Sahni never suggests eating less to make up for a day.
Ask how much a household portion weighs, such as 3 large eggs or half a cup of cooked rice, and Sahni answers from USDA FoodData Central portion weights.
Nothing you share is stored: each answer is calculated from that request alone. These are general nutrition targets, not medical advice.
