Log what you eat from about 13,600 USDA foods, a barcode, your own foods and recipes, or a quick calorie and macro entry. Each day shows calories, protein, fat and carbs against your targets, plus vitamins and minerals as a share of the FDA Daily Values. Weigh in when you like; the page draws a smoothed trend (an exponential moving average, about a 10-day window) so one salty dinner doesn't look like a fat gain.
It starts from the Mifflin-St Jeor formula and your activity level. After that it learns from you: over the last two weeks, average intake on fully logged days minus the weight change (a straight line fitted through your weigh-ins, at 7,700 kcal per kg, about 3,500 per lb) gives what you actually burned. The estimate moves toward that a little each day, more when you log more days, so it settles after two to four weeks of steady logging. Mark a day as not fully logged and it's left out. At each weekly check-in your targets are reset from the current estimate and your goal rate.
USDA FoodData Central (public domain): Foundation Foods, SR Legacy and the FNDDS survey foods for search, and about 431,000 barcodes from the Branded Foods data for scanning. The files are downloaded from this site and searched on your device; a barcode only looks in that list, so if a product isn't in it, the page says so and you can save it as your own food. Missing values mean USDA didn't record that nutrient, not that it's zero.
In this browser's storage on this device: your log, weights, measurements and photos. There's no account and nothing is uploaded. The camera picture for barcode scanning is read on the page and never leaves it. Browsers can clear site data (Safari can after seven days of use without a visit to this site), so use Export now and then, and Import to restore or move to another device. If you keep this page open in two tabs, each one picks up what the other saves.
No. The numbers are estimates from averages and your own logging. If you're pregnant, under 18, have a medical condition or plan to eat far below your expenditure, talk to a doctor or registered dietitian first.
