Gallup's annual survey on Consumption Habits*, conducted July 7-10, finds that Americans report that they have tried to lose weight an average of seven times in their lives. This includes 24% of Americans who have tried to lose weight once or twice, 28% who have tried between 3 and 10 times, and 11% who have tried more than 10 times. A third of Americans, 34%, say they have never tried to lose weight.
