A study reported that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet and exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds of 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15% of their body weight.Dog owners didn’t lose any more weight than those without dogs but,say researchers,got more exercise overall—mostly with their dogs—and found it worth doing.
