Levels of exercise also fell, as did consumption of fruit and vegetables.
The American Journal of Medicine study found those with health problems were no more likely to follow a healthy lifestyle than their fitter peers.
Researchers at the Medical University of South Carolina compared two large-scale studies covering the period 1988 to 2006.
During those 18 years, the percentage of adults aged 40-74 years with a body mass index (BMI) greater than 30 rose from 28 percent to 36 percent.
“If we want all Americans to achieve the health benefits of a healthy lifestyle, then all members of society must take action ” said Dr Steven Galson Acting US Surgeon General.
The number of people exercising three times a week or more fell from 53 percent to 43 percent, while the number of people eating five portions of fruit and vegetables a day fell by nearly 40 percent.
At the same time, smoking levels remained the same and moderate drinking slightly increased.
Overall, researchers found, the number of people adhering to all five "healthy habits" - including maintaining a healthy weight and stopping smoking - decreased from 15 percent to 8 percent.
