Title: A Simple Dietary Message to Improve Dietary Quality for Metabolic Syndrome
Brief Summary: Identifying a simple dietary recommendation for weight loss and metabolic health may demonstrate potential for a simple public health message to impact coronary heart disease (CHD) prevention and metabolic syndrome. In a randomized clinical trial, the investigators propose to compare the efficacy of two intervention approaches to dietary change for CHD prevention among persons with metabolic syndrome. The two approaches are 1) the AHA Dietary Guidelines; and 2) a simple dietary change condition that focuses on increasing fiber. The investigators hypothesize that a message promoting high fiber intake may be the simple message that has potential to produce broad impact.
