Get a dog, lose weight.
A number of studies have linked owning a dog to losing weight.
A year-long study at the Wellness Institute at Northwestern Memorial Hospital, Chicago found that walking an overweight dog helped both the animals and their owners shed unwanted pounds. Researchers found that the dogs provided support in similar ways to a human exercise buddy, but with greater consistency and without any negative influence.
Another study by the Research Center for Human-Animal Interaction found that public housing residents who walked therapy dogs for up to 20 minutes five days a week lost an average of 14.4 pounds in a year, without changing their diets.
A third study, conducted by dog food manufacturer Mars Petcare, found that people with a dog walked 30 minutes more per week than they did before owning a dog.
