Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iPhone application (应用程序) MealSnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.

MealSnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iPhone applications. The application gives users a quick reply. To do that, it matches the taken picture to a databank (数据库) with the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.

We started with something simple—an apple. A couple of minutes later, the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of a mixed salad bowl. MealSnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 789 calories.

Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That is why it is so popular among those who are trying hard to lose weight.

In addition, MealSnap can act as a food diary. No need to write down what they’ve eaten, the photoes will be stored. The users can keep a visual log (视觉的记录). Mr. Smith said, “it’s like a food journey, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological (心理的) change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.”
