Ask U.S. adults if they’re trying to lose weight, and 3 out of 4 say “yes,” polls show. Weight loss is a major industry, from support programs to diet books to special foods. Yet more than 60% of Americans are overweight, and the numbers are getting higher.
With all this dieting, why are so many people still unsuccessful at controlling their weight? One reason is that although many people manage to lose weight, they usually don’t keep it off.
