Log breakfast, lunch, dinner and snacks by photo, by text or by hand. Nutriglance helps estimate calories, protein, fat and carbs, saves each entry in your food diary and shows how much is left of your daily target.
A food diary is a running record of everything you eat and drink with the calories and macros attached. Kept for a week it shows two things almost nobody guesses correctly: how big their portions actually are, and which two or three meals account for most of the day.
It only works if it is complete. A diary with the awkward days left out tells you less than no diary at all, because it still looks like evidence. If you do not have a daily number to log against yet, start with the calorie calculator.
Related: calorie calculator, macro calculator, how accurate the estimates are. Nothing here is medical advice — see our health disclaimer. If tracking is making your relationship with food worse, that is reason enough to stop; in the US the National Alliance for Eating Disorders helpline is 1-866-662-1235.
Here is one day in the diary: meals, calories, macros, water and what is left of your daily target, all on one screen.
| Meal | Dish | Kcal | Protein | Fat | Carbs |
|---|---|---|---|---|---|
| Breakfast | Porridge with banana and yoghurt | 340 | 11 g | 8 g | 58 g |
| Lunch | Chicken breast, buckwheat, vegetable salad | 520 | 42 g | 15 g | 54 g |
| Snack | Cottage cheese 5% with berries | 180 | 24 g | 5 g | 8 g |
| Dinner | Fish with vegetables | 410 | 35 g | 18 g | 22 g |
Old-style diaries make you search for every product by hand and fiddle with gram amounts. In Nutriglance you choose whichever way of adding food suits you.
Photograph the dish: the AI helps identify what is in it, estimate the portion and add the calories and macros to your diary. You can check and edit the result.
Write it as a normal sentence: “buckwheat 150 g, chicken 120 g, salad”. The service parses the description and saves the items to the right meal.
If you want a more precise entry, add the product, weight, calories and macros yourself. This works well for home recipes and packaged food with a label.
The diary shows not just individual dishes but the whole picture of your day: calories, macros, water, meals and trends.
When you are losing weight, what matters is seeing the real picture across the day and the week. The diary captures sauces, drinks, snacks, coffee add-ons and the portions that are easy to underestimate.
You set a daily target, say 1 800 kcal, and log food after each meal. The diary shows how many calories are left and how protein, fat and carbs are distributed. That makes it easier not to leave everything until the evening, when half the day is already forgotten.
Important: calorie and nutrition guidance does not replace a consultation with a doctor. If you have a medical condition, are pregnant, have an eating disorder or any medical restrictions, please see a specialist.
Compare a manual calorie diary with an AI diary and pick the way of tracking that suits you.
| Criterion | Traditional food diary | Nutriglance |
|---|---|---|
| Adding food | Search for the product by hand | Photo, text or manual entry |
| Composite dishes | Have to be broken down into ingredients | The AI estimates the whole dish |
| Speed | Depends on the database and your experience | An entry takes just a few taps |
| Macros | Often visible only after manual selection | Calories, protein, fat and carbs are saved to the diary |
| Progress | Not always linked to water and weight | Food, water, history and trends in one place |
| Accuracy | Depends on the weight and the product you pick | The AI result can be checked and adjusted by hand |
These examples show how a day of eating can be structured for different goals. They are not a ready-made diet, just a template for understanding diary entries.
The diary works for a range of goals: losing weight, staying in shape, gaining muscle, analysing eating habits and preparing a report for a specialist.
Track your daily target, snacks, drinks and weight trend — with no promises of instant results.
Track protein, total calories and meal regularity alongside training and an active lifestyle.
Understand your usual diet, the calorie content of your favourite dishes and your weekly trend.
Spot recurring patterns: late-night snacks, sugary drinks and irregular meals.
Show your diet to a coach or dietitian without messenger screenshots or hand-written reports.
The diary lives online, so it is easy to fill in from your phone after every meal.
AI analysis speeds up filling in the diary, but it is not a medical diagnosis, a personal diet or laboratory-grade accuracy. Results are affected by the camera angle, the light, which ingredients are visible, sauces and the real portion weight. That is why in Nutriglance every result can be checked, edited and refined by hand.
