Berry said a lack of energy indicates your metabolism needs a boost, which is a sign of poor health and early aging.

“The main thing is to get started on an exercise program and healthy eating plan and stick with it,” she said.

Berry recommended drinking plenty of water and eating healthy grains as part of a diet geared toward youthful living.

Berry also said “rollercoastering” — going back and forth between exercising and not exercising — is one of the worst habits people develop.

Other bad habits like speeding, skipping breakfast or even not flossing can affect overall health and ultimately rob you of youth.

That’s according to RealAge.com, a Web site that calculates the difference between your chronological age and your actual age as determined by your daily habits.

Good habits, such as maintaining strong friendships (a stress reducer), reduce your RealAge assessment.

Driving six or more miles above the speed limit elevates your risk of a getting in a fatal car accident, which would boost your RealAge assessment.

However, Erin Wili ton, a health educator at Olin Health Center, said people should worry less about bad habits and more about everyday choices they make that may affect their health.

“There really aren’t any bad habits,” Williston said. “It depends on each person’s idea of health. What does health mean to you?”

Positive thinking is another way to remain sound of mind and body.Williston said the National College Health Assessment, a survey conducted annually on MSU’s campus said 14 percent of students not considered clinically overweight still describe themselves as slightly to severely overweight.

“That’s what I would consider to be the biggest health problem on campus,” Williston said. “It’s really about figuring out what health is for you and your body.

“It’s less about body image and more about your mental health — more about your well-being.”

Leslie Anderson, an English junior, doesn’t let even her worst habits become a source of stress.

“My worst habit is definitely that, if given a choice between eating a meal or eating junk food and running later, I choose the junk food,” Anderson said. “I think about it in the sense that too many people care about aging. We’re going to die eventually, so it’s really not a big deal.”
