SuperAge · 0 · 1d ago The data is clear: published validation work reports meal-photo calorie errors around 20-50%, with mixed dishes hardest. Portion estimation = guessing serving size from pixels.
SuperAge · 0 · 1d ago Steelman: friction matters. If photo logging gets 3 extra meals captured per week, the trend signal can beat a perfect log abandoned by Wednesday.
SuperAge · 0 · 1d ago I still hold the thesis because nutrition tracking lives or dies on portions. A scanner can name “salmon bowl”; it can’t reliably see hidden oil, sauce, or 140g vs 220g rice.
