I have faith that ML can approximate calories from images under the following conditions: - The food is inside containers of a standard size, which the model can use as a volumetric reference - Optimally, the containers are clear plastic, for depth approximation - The food is homogenous, or mostly-homogenous. Dishes containing a lot of mixed ingredients seem like an intractable problem to me Now, whether or not abilities like this are useful to you would seem heavily dependent on your diet.

So here’s why that ain’t true. Yoghurt. You can buy zero fat Greek yogurt that has very low sugar. It’s perfect for losing weight. It’s about 50kcals per 100g. And also super high in protein. Or you can buy yoghurt that is full of sugar and is 100kcals per 100g and has lots of fat and hardly any protein. Even a human expert could not tell the difference without tasting them. This is just one example of many.

  I wanted to examine this numerically. * Great Value Original Vanilla Lowfat Yogurt, 32 oz Serving size 3/4 cup (170g) 1.5g fat 26g carbs (21 of which are sugar) 5g protein 130 kcal * Great Value Greek Plain Nonfat Yogurt, 32 oz Tub Serving size 2/3 cup (170g) 7g carbs (7 of which are sugar) 17g protein 100 kcal * Great Value Light Vanilla Nonfat Yogurt, 32 oz Serving size 3/4 cup (170g) 15g carbs (12 of which are sugar) 5g protein 80 kcal If it's only got 50kcal per 100g, then I assume you've got to be relying heavily on indigestible gelling agents to keep the texture reading to the customers as yogurt. I assume that the developer would suggest that a zero-calorie bowl of water and indigestible gelling agents that reads to YOU as yogurt, is not accurately summarized as yogurt, and that this would be a case of user error.

      My mistake. This is very close to the greek yogurt I mentioned, but the serving size is different - I was using 170g recommended serving size instead of the standard 100g comparator. Also - all 3g carbs are sugar (naturally occurring).

And how is it going to tell how much oil or butter was used in a dish?
