Folks who want to get in better shape and eat healthier are often encouraged to make one change at a time, but a new study finds that people are the most successful when they tackle their diet and exercise habits simultaneously.
“It comes down to making them both priorities and thinking about both throughout the day,” says lead researcher Abby King, professor at the Stanford (University) Prevention Research Center.
King and colleagues worked with 200 inactive, mostly overweight people, 45 years and older, who had relatively unhealthy diets that didn’t include enough fruits and vegetables and contained too much saturated (animal) fat.
Published online in Annals of Behavioral Medicine, the study shows participants were divided into four groups: One learned to make diet and exercise changes at the same time; another learned to make diet changes first and then a few months later began working on their exercise habits. A third group changed their exercise habits first, then their diet later. And the fourth group learned stress-management techniques but did not get diet and exercise guidance.
Participants weren’t trying to lose weight, just live healthier lifestyles. Health educators met with them at the beginning of the year and then called them once a month to provide advice and support.
The goals were for participants to meet the government’s physical activity guidelines of doing at least 150 minutes a week of moderate-intensity physical activity, such as walking, eat five to nine servings of fruits and vegetables a day and keep their saturated fat intake to 10% or less of daily calories.
The findings after one year: Those who made changes in their diet and exercise habits at the same time did the best at meeting all three goals — eating enough fruits and vegetables, limiting saturated fat and exercising enough to meet the government’s guidelines.
