High-Tech Weight-Loss Tools

Apps

How they work: Apps allow you to track calorie intake and log workouts on your smartphone.

How they help: Many studies have shown that keeping a food or workout journal can increase weight loss. But it can be a pain to whip out a notebook several times a day, then add up calories or miles logged on the track. Apps are portable and make the accounting feel like a game.

Ckeck out: Lose It! tracks diet (there’s nutritional information for more than 50,000 foods), exercise, and weight loss. MapMyFitness tracks workouts and can even help you find running, walking, and biking routes in your area.
