Guide: how to log food with a photo in Lingo

Point your camera at your plate, capture the photo, and Lingo fills in the rest. Here’s how to log a meal in seconds — and what you get back once you do.

Your glucose graph shows you a rise at 1:40 pm. But a spike on a graph can’t tell you what caused it.

That’s the reason why we log. A Lingo biosensor records what happened inside your body. The log exists for you to record what you did at that time. Put the two together and a peak on a graph turns into a pattern you can learn from, noticing “Ah-ha. This meal caused that rise ... at this time of day. And it happened again the following Tuesday.”  
 
You eat. You log. You learn. The tricky part has always been that middle step. Taking a minute or two to log a meal might just be a minute or two you simply don’t have. It’s just enough friction that many of us are missing out on the biggest insights personal glucose tracking can reveal.

And that's the goal of our latest software release — to take the work out of every log. Because the more you log, the more you learn. Now you can just photograph your plate, check what comes back, and tap log.

Why logging meals is the step that matters

A glucose spike on its own is a data point. A spike attached to a meal is information you can act on.

Think about a day you logged nothing. You open the app in the evening and notice three spikes. You can guess the first one — maybe the sugar in your morning coffee on an empty stomach?— but the mid-afternoon rise could be the second coffee, the granola bar you grabbed from the break room mid-afternoon, that meeting that felt like it was never going to end, or all three. You end the day with a few falls and rises and no explanation, so there’s little you can learn from.

A day of logs looks entirely different. The spikes have meals with details attached to them. And once a handful of days have these details, you’ll probably read less about the actual meals and read more about yourself — this combination of foods was gentle on my glucose, that one wasn’t, this one is fine at noon, but didn’t do me any favors after 9 pm.

Eat, log, learn. And repeat, making tweaks to see what changes — and what didn’t. That’s the loop that can drive transformation with Lingo.

People who log regularly are nearly 2X more likely to see meaningful glucose improvements*.

*Among Lingo users with hyperglycemia (avg glucose 117-140) who tracked more than 50% of sensor days.

And every log is an unlock, which makes sense. Because every meal logged is one you can learn from. Better still, a pattern you’ve spotted is one you can act on next time.

How to log a meal with a photo

1. On the Today screen, tap Log event.

• Select Food.

• Tap the camera icon in the search bar.

• Snap a photo, or choose one from your photo library.

• Caption: Frame the full plate so the app has the full meal to analyse.

• Review what comes back. Look good? Tap Log.

Lingo reads the photo and suggests the foods it recognises. You’ll see them listed with portion sizes. Check the list against what’s actually on your plate, adjust anything that might be off, then log it.

If the photo doesn’t get it right  

A photo gives the app a lot to work with, but it won’t always get it right. Some meals are harder to read than others, like meals mixed into a bowl, anything under a sauce, or sometimes, just a portion might be hard to distinguish. That’s when the review step earns its place. Before you finalize the log, you can:

• Adjust a portion that came back too large or too small

• Remove an item the app picked up that isn’t there

• Add an item it missed (you can use the search bar to add it)

If you missed your photo opp, you still have two alternatives:

• Search the food databased by name

  • Reuse a recent meal — the fastest route for those of us who have our go-to meals week after week

Use whichever is easiest for you — or the meal in front of you. They all end up in the same place.

Where to find the nutrition breakdown

For every food you log, you’ll also get a record of its nutrition breakdown. Just tap any logged meal to open its Event Detail page. Below the meal you’ll find a nutrition breakdown, including protein, carbs, fat, sugar, and fiber.

Useful things to know

Nutrition details are estimates, not measurements. Lingo uses AI to identify foods from the image and estimate portions from what it can see. A photo can’t see everything in the meal. Oil in the pan, butter on the toast, dressing already tossed through the salad. A camera captures what’s on the plate, but might miss a few details, so you may want to consider adding things you consider significant in the review step.

The breakdown describes the food, not your response. Two people can eat exactly the same meal and see two different glucose responses. That’s why Lingo exists. Use the nutrition breakdown as a reminder of what you ate, and your Lingo graph as the record of how your body responded to it.
