FAQ
How accurate are photo-based macro estimates?
They are directionally useful but not lab-accurate. Mixed dishes, hidden oils, and unclear portions reduce precision.
What kind of photo gives the best result?
Use a clear, top-down image in good light with the full plate visible and minimal blur.
Can I use this for restaurant meals?
Yes. It works best as a quick estimate before deciding your next meal or snack adjustments.
Should I replace manual logging with this?
Use it as a fast triage tool. For high-precision phases, combine with manual tracking on key meals.
Is this medical advice?
No. This is educational nutrition guidance only.
