A bowl of rice, a plate of braised pork and a side of vegetables may look like a simple lunch. For anyone trying to manage their weight, the harder question is often: How many calories are actually on the table?
On July 29, Chinese health app Ant A-Fu launched a new photo-based food tracking feature. Users can take a picture of their meal, and the app will identify the food, estimate the total calories and provide a breakdown of protein, carbohydrates and fat.
Meals can also be recorded by typing, speaking or adding notes to a photo.
The feature is designed to make food tracking less of a chore. Keeping a daily record often means searching for each dish, guessing portion sizes and entering numbers by hand. A quick photo removes some of those steps and makes it easier to see how small snacks and everyday meals add up over the course of a day.
Once a meal is saved, it becomes part of the user’s personal health record. The app can flag meals that appear high in calories and suggest lighter options for the next meal. It may also recommend exercise based on the user’s health information and weight-management goals.
Users can correct the result when the app gets a dish, portion size or meal time wrong.
Ant A-Fu, previously known as AQ, also offers health information, personal health records and other wellness services. Some wearable devices can be connected to the app to sync data such as steps, heart rate and sleep.
A food photo cannot capture every detail. Cooking oil, sauces, sugar and exact portion sizes are difficult to judge from an image alone, so the calorie count should be treated as an estimate rather than a precise measurement.
The feature works best as a practical food diary. It helps users notice what they are eating, where extra calories may be coming from and what they could change at the next meal.
Healthy habits rarely begin with a perfect plan. Sometimes they start with a photo of lunch, half a bowl less rice and a short walk after dinner.
