The problem
You eat a meal. The photo app sees two thirds of it.
Missed: 250 to 345 cal per meal
NIH researchers ran 102 weighed meals through four photo calorie apps. Every one of them came in low, by 250 to 345 cal per meal on average: roughly a third.
Study by the NIDDK (NIH), presented at NUTRITION 2026, the American Society for Nutrition's annual meeting, on July 25, 2026. Preliminary results: a conference abstract, not yet published in a peer-reviewed journal. Read the press release
Underestimate just one meal a day by 300 cal, for a month:
9,000cal
Over 2 lb of fat. In theory.
The math: 300 cal × 30 days = 9,000 cal = 1.17 kg = 2.6 lb, at roughly 3,500 cal per pound of fat (7,700 cal per kilo, an approximation).
What about weighing everything by hand?
It works, on paper. But it costs you time and energy at every meal, and real life doesn't happen with a scale in your pocket.
- Get out the kitchen scale
- Wonder if the rice was weighed raw or cooked
- Type in every ingredient, at every meal
- At a restaurant, take a wild guess
That's exactly where people give up.
The solution
Let your AI do it.
Yourplate plugs into the assistant you already use: ChatGPT, Claude, Mistral Vibe, Claude Code, Codex… You explain your meal the way you'd tell a friend. It finds the foods in official nutrition tables, sizes up the portions you didn't weigh and fills in your diary.

What should I eat tonight?
It's 6 PM. You have 350 cal left, mostly carbs: you've almost hit your protein.
Tonight, I'd go for a big bowl of vegetable soup, two slices of whole-wheat bread and an apple. About 340 cal, and your day lands right on target.
