MyFitnessPal helps you shed those extra pounds (pictures)

MyFitnessPal helps you stick to your health goals by tracking the calories in the food you eat and the calories you burn during exercise. The homepage gives you an overview of how many calories you've consumed and burned, based on what you've recorded in your Food Diary. It also shows a feed of recent updates from your friends in the app.

Your diary keeps track of all the food you consume, and how much you exercise in a given day.

When you make a new entry in your diary, you have a few options to find and add your foods. You can either pick from your list of recent items, search by keyword, or use the barcode scanner.

When you find the food you're looking for, tap on it to see the serving size and nutritional information. You can edit the serving size to match what you ate.

You can record physical stats in the app, including weight and body measurements. As you make new entries, you'll see a graph charting your progress.

When you finish your diary for the day, MyFitnessPal tells you how much you'll weigh in several weeks if you maintain the same eating and exercise habits. It also offers advice if you're not getting enough calories, or are eating too much to meet your weight goals.
