Calorie counting is a tedious, impractical activity for anybody who isn’t even entering a bodybuilding competition. Just go on a total deficit with high-quality foods, whatever the composition.

How do you know you are on a total deficit if you don't count calories?

You lose weight after a week.

My body is perfectly capable of eating an entire jar of peanut butter with an entire jar of honey on the side in one sitting, so, no.

Oh interesting. I wouldn't put it past them that they include that data in the input though. Why are you certain they don't? (I guess that they don't, too, because someone reported getting identical calorie readings from giving photos to Gemini 1.5 directly)

They’re using some off the shelf multimodal LLM API, perhaps Gemini 1.5 or something else. And no off the shelf VLM API is capable of handling 4 channel images (RGB+D).

You can take crude measurements from the depth map and provide as text. Or perhaps provide the depth map as an image next to the actual image as those are certainly in training data. I haven’t tested these

Sure, that means that 6 shots of gin basically replaces one whole meal.

If 550kcal is one whole meal to you, then 6 shots of gin will get you absolutely blasted, probably black out too.

That's nonsense. A shot of spirits is one unit of alcohol. A pint of strong-ish beer like Stella Artois is 3 units. 550 calories is easily a dinner's worth for a woman of 70kg, or a man that's heavier but trying to gradually lose weight. Either of whom would normally not be too affected by two pints of Stella.

What is nonsense? Go to https://alcohol.org/bac-calculator/. Putting in the numbers for a 150lb woman drinking 6 shots over 2 hours gets you 0.21% BAC, which is plenty enough for black out drunk.

I see. That looks a lot like it's applying a Widmark-style model [0], which assumes that absorption is instantaneous, and that drinking starts in a fasted state unaccompanied by food or water. I guess that makes sense if we're literally talking about replacing a whole meal with alcohol. But normally I imagine cutting back on portion sizes so that I can have some drinks later. I don't know about other users but the idea that an 80kg man will have body control or speech impairments after 3 pints (60oz) of beer over 3 hours just feels wrong. Especially if they start after dinner and have a glass of water in the middle.

Yeah good point. It’s saying a bottle of wine gets you to 0.3% which basically is close to dying, so it’s not realistic. Still six shots is equivalent to 6 beers or a bottle of wine, so it still affects you quite a lot.

No it's not. Stella is 5.2% in the strongest form (some places sell a weaker version that is 4.6%). Both are roughly standard ABVs. At worst, a 20 oz 'pint' of Stella would be ~1.7 units. In most places in the US, a pint is 16 oz, so it would be ~1.4 units. Two pints at worst is slightly over 3 units total.

I agree it's a fair amount of booze. Especially at 1.5oz per shot. In the UK a single is officially more like 1oz, so 6 UK shots is 4 US shots.

Probably because most people likely to use this app aren't going to be using it for serious self-monitoring like someone with diabetes would. The reality is that most people will use an app like this for a while, fail at their attempt to lose weight or gain muscle, and lose interest. "Good enough" is the mantra of much of what is in the health/nutrition/fitness niche and it goes beyond anything AI-adjacent.

Good enough isn't close to cutting it for weight loss. A 250 calorie surplus per day will add half a pound per week. That being off by two tablespoons of oil.

"Good enough" being that it doesn't matter because most people who use it probably aren't going to seriously stick it out to see results as they either won't put the work in or won't seriously stick to a diet for any meaningful length of time.

I do agree though, it isn't fit for purpose, like much of what's available beyond AI.
