Here are a few well-regarded weight-loss programs to consider, courtesy of a report in the New York Times.

• LOSEIT (iPod Touch, iPad and iPhone; free): Tell the app how much weight you want to lose and how many pounds per week you want to take off, and it calculates the amount of calories you can consume each day. LoseIt has a database of 40,000 food items and can also calculate how many calories your daily exercise burns up.
• CALORIE COUNTER by FatSecret (works on all platforms; free): This program works much like LoseIt. But one advantage is that when you enter your basic information, you can sync up with the FatSecret Web site. The site has forums where users can swap ideas about diets, recipes and working out.
• TAP & TRACK (iPhone, iPod Touch and iPad; $3.99): This app costs $4, but users say it’s worth every penny. The program helps you come up with a daily calorie goal and features a large food and exercise database.
• WEIGHT WATCHERS MOBILE (iPhone, iPod Touch and iPad, BlackBerry and Windows Mobile 6; subscription required): If you already follow Weight Watchers or Weight Watchers Online, consider their app or one that can track the points used in their diets. Free for online subscribers, Weight Watchers Mobile lets you track and calculate points and see your weight loss history.
