I don't believe the authors of this study are stupid.

If there are apps targeting people with diabetes that claims to count your carbs with AI, why haven't those been analysed? That would be a far more effective claim.

I based the study off of the clickbait article that they wrote about the study - i'll read through the study to see whether they analyse that, but it would be far more effective to see if the 'carb-counting' AI app is returning similiar results to the frontier model - that's an interesting result that actually can forward discussion.

There are very popular apps on the App Store right now that are going viral among non-techie people that do exactly this, and they have no concept of how AI works. My wife was talking about one and I had to give her a reality check that the AI had no idea what ingredients were used to make the food. And she's a licensed nutritionalist.

Studies like this create something to point at for people who are confused and serve as a springboard for a conversation in the media.

I am... unsure why anyone would think LLMs would be able to do this. They are not magic oracles. Like I think even most humans would be extremely bad at this. Like, are people actually using LLMs for this? Please do not, it won't work.

If the LLM can correctly identify a food item some high percentage of the time, why would it be magic for it to guess the amount of calories in an object? It's perhaps a lookup and some simple math as an extra step.

The paper itself is a lot clearer about the purpose. The blog post reads very clickbaity and doesn't really explain the context well.

I disagree, it clearly explains that AI carb counting apps are a problem and shouldn’t be used.

They’re writing in a neutral way that reaches their audience without lecturing or being condescending. They lead the reader to the conclusion rather than shoving it at them. I think that’s why it’s triggering so many angry comments on HN, but it’s effective for the audience they’re writing for (non technical people who may need convincing but don’t like being preached at)

There are apps in the app store right now that pretend to do this kind of thing, so having somebody actually show that it doesn't work is valuable, even if we already knew the outcome ahead of time.

I suppose i'd much rather a study analyse the apps in the app store that are attempting and claiming to do that kind of thing - rather than the base model they might be using.

They're marketed as AI. AI has a long standing image built up by movies and other media of being some omniscient computer capable of analyzing the world. These AI companies are very aware of this and leverage it. And a person with sufficient knowledge could easily give a rough estimate of the calories. A slice of store bought sandwich bread of a given thickness generally has calories within a certain range. So do che…

> Packaging on food also always has calories, so clearly people know how to estimate it fairly accurately.

That's not done by looking at it and guessing (or at least it _shouldn't_ be; manufacturers have been known to do this but it's bad practice and may cause them regulatory problems). In an ideal world it's done with one of these: https://en.wikipedia.org/wiki/Calorimeter ; less ideally it can be estimated based on the ingredients.

If there are commercial services where you take pictures of food and are promised a realistic (paid for) response, then yes. And there are.

But it's stupid. If i smack myself in the head with a hammer is that proof hammers shouldn't be relied on?

No, but it would be proof you didn't get the point of the paper.

Because the apps aren’t going to let you submit 29,000 automated requests for statistical analysis.

And if you did, the authors of those apps would just release an update saying they changed models and try to dismiss the study.

The vitriol against this article on HN is sad. Commenters who agree with the article and its conclusions are grasping for reasons to be angry about it anyway

From the text of the article I believe the author is implying there are apps doing exactly this, and so this is why it was studied that way. Had the author written the article themselves rather than an LLM their motivation probably would have been clearer.

> there are apps doing exactly this Yeah, for sure there are. And people will just ask ChatGPT as well. The funny thing is that for people who are just trying to lose weight without managing any health issues precisely, this type of extreme variance doesn't really matter, because the mere act of consciously quantifying food consumption is, based on my experience counting calories, the single biggest factor in success…

I actually think "just asking ChatGPT" is fine, because A) the data in these apps is suspect at best and B) the data behind calories is also pretty suspect (but we all play along because we can adjust other variables to make it all "work" well enough).

Once or twice a year I spend a few weeks meticulously measuring ingredients/cooked foods and recording calories and on complex recipes apps are next to useless at getting accurate data. You're trying to input five or ten relevant ingredients, and then weighing your cooked outcome to try and divide the ingredients by proportion. Frankly it's a mess and most people aren't doing it for home cooked meals, and are getting very lossy outcomes (weighing cooked chicken and marking it as raw chicken, etc)

With reasoning and tool calling (combined with me meticulously weighing before and after), it's producing fine data for my purposes.
