Nutrivity.net, Minneapolis

Rather than attending meetings, taking expensive supplements, or eating unappetizing frozen dinners, members of Nutrivity Weight Loss lose inches and nourish their bodies with from-scratch meals they prepare in their own kitchens. The process is a simple one: during their first visit to the website, users enter in their height and weight, age, and fitness level, along with their dietary preferences and the number of people they’d like to feed. Members then create a seven-day meal plan customized to their caloric needs and hatred of kale that features recipes designed by award-winning chefs. To ensure members can prepare the recipes without hassle, the program devises a shopping list—organized by store aisle—that includes each ingredient needed for the week’s meals. Members get further guidance through the website’s wealth of online forums and Q&As with registered dietitians.
