Meta has quietly but purposefully announced a new feature for its Ray-Ban smart glasses that packs a punch: Nutrition tracking via AI. In future, anyone wearing Ray-Ban Meta glasses can simply take a photo of their food or issue a voice command – and the embedded Meta AI analyzes the meal, extracts nutritional information and logs it in the Meta AI app. That sounds practical, but it also raises a few questions.
Nutrition tracking with Ray-Ban Meta: how it works
The new feature is aimed at users of the Ray-Ban Meta smart glasses (without display) and the Meta Ray-Ban display glasses. A meal can be captured by voice command or photo, whereupon Meta AI reads out and saves the nutritional data. Personalized tips and insights are then provided based on the collected nutritional data – for example, answers to questions such as “What should I eat to have more energy?” The feature will initially be launched in the USA for users aged 18 and over; according to Meta, wearers of the Ray-Ban Meta Display version will receive it in the summer.
The explicit look into the future is also interesting: Meta has announced that the glasses will automatically recognize and log what has been eaten in the long term – without the user having to take any action. This so-called “ambient” tracking would be a real game changer for people who want to keep a consistent eye on their diet.
The big but: data protection and battery
As tempting as the idea sounds, the catches are obvious. In order for the glasses to automatically recognize meals, the camera would have to be permanently active. This is problematic for two reasons:
- Data protection: a constantly running camera on your head – this is likely to cause considerable skepticism among passers-by, friends and the public. Smart glasses are already under data protection scrutiny as their cameras are barely visible.
- Battery life: A permanently active camera would drain the glasses’ battery in no time at all. The current models have a battery life of around eight hours – this is likely to be significantly less with continuous recording.
Meta itself is keeping a low profile on these points. The vision is there, but the technical implementation is unlikely to happen in the foreseeable future. For the time being, tracking is limited to manual triggering by photo or voice command – which is at least much more convenient than conventional calorie counter apps.
Other new features for Ray-Ban Meta glasses
Nutrition tracking is not the only thing Meta has announced for its smart glasses. The following new features were announced at the same time:
| Feature | Availability |
|---|---|
| Nutrition tracking (manual) | Coming soon, initially USA (18+), display version summer 2026 |
| Hands-free WhatsApp summaries | Coming soon, initially early access program |
| Display recording (Ray-Ban display) | Coming soon |
| Instagram Reels scrolling (display) | Coming soon |
| Glanceable widgets (weather, calendar, stocks) | Coming soon |
| Spotify shortcut | As of now |
| Neural Handwriting | In the coming weeks |
Neural Handwriting is particularly exciting: you literally write messages with your finger in the air or on a surface – the glasses recognize the finger movements and transfer the text. The feature should be compatible with WhatsApp, Messenger and iMessage.
The hands-free WhatsApp summaries make it possible to have group chat content read aloud or to ask specifically what a contact has written recently – all without a smartphone in hand. Meta emphasizes that these interactions are processed directly on the device and are end-to-end encrypted.
Classification: Sensible, but with a sense of proportion
Nutrition tracking is a clever move by Meta to position the Ray-Ban smart glasses as a health wearable. The idea of using the glasses’ camera not only for photos and videos, but also for your own everyday health is an obvious one. The current status – manually triggered photo analysis – is a realistic first step.
However, the long-term goal of recognizing meals fully automatically in the background is a completely different ball game. Anyone who is prepared to hand over their nutritional data to Meta needs to think carefully – after all, the company has had several problems with data protection in the past. And a permanently running camera on your head is likely to meet with considerable resistance from society.
