Physicians are aware of the effects of diet, exercise and weight on cardiovascular risk factors, yet they may be reluctant to address nutrition and physical activity with their patients. Lack of time, a belief that lifestyle changes don't work, and not knowing how to counsel patients all contribute to a doctor-patient silence around this important topic.

Dr. Robert Eckel, MD, President of the AHA, suggested that devoting three minutes of an office visit to a discussion about lifestyle habits can help patients increase their physical activity and choose healthier diets.

“We live in a toxic metabolic environment that sabotages our patients' health,” Dr. Eckel said. “We cannot simply rely on technological advances and medications to defeat cardiovascular disease.”

He emphasized that patients are more likely to implement important lifestyle changes if they receive advice from their physician.

“In just three minutes - the time it takes to order and receive a hamburger, soda and french fries at a McDonald's restaurant, we can do something to help our patients make healthier choices,” Dr. Eckel said.
