The world’s biggest food group, Nestle, has launched an online program inviting pet owners to team up with their furry friends and lose weight. Nestle’s pet and people weight management units Purina and Jenny Craig worked together on “Project: Pet Slim Down,” an online program. Pet owners who sign up can obtain tips for exercising their pet, record exercises taken, track weight loss, and share photos with other users, Nestle said. Users can also follow five overweight cats and three dogs on their weight-loss journey via small movies and before-and-after pictures. A rep for Jenny Craig said “Two thirds of adults in the U.S. are overweight or obese, and more than half of all pets in the U.S. are also battling the bulge.” The World Health Organization said 1.5 billion adults were overweight in 2008.
