Examining Real Weight Loss Attempts with Meal Replacement Program Participants: Efficacy, Social Support, and Undermining
Unformatted Document Text:  In August 2004 the National Institute of Health (NIH) announced: “Obesity is one of the most daunting challenges of the 21 st century. On the surface, it may seem that the solution to the obesity epidemic is obvious: ‘Get people to eat less and exercise more.’ The reality is that this change is very difficult to accomplish, and research is critical to address the issue successfully. Given the complexity and multiplicity of the forces driving the obesity epidemic, the NIH recognizes that it cannot, by itself, solve this major public health problem (NIH, 2004, p. 5).” Scientific evidence in the last decade has demonstrated that physical activity and balanced diet can improve the quality of life for all ages and conditions. Unfortunately, it has not translated into consistent action. Dieting has become America’s new national pastime; $33 billion is spent annually on weight loss products and services (NIH, 2004). Despite the benefits of regular physical activity, less than 25% of adults report achieving the Center for Disease Control’s recommended amounts of physical activity (CDC, 2001; 2003). Most individuals who try to lose weight have trouble with program adherence. For instance, comprehensive behavioral programs providing weekly group treatment of 20 to 26 weeks produce average losses of 8 to 10 kg (approximately 9% of initial body weight) and have attrition rates ranging from 15% to 20% (Phelan & Wadden, 2002). Less intensive interventions provide patients with treatment manuals and minimal or no therapist contact, and produce weight reduction of only 1 to 5 kg over 6 months (Wing, Venditti, Jakicic, Polley, & Lang, 1998). One specific group of people that this issue affects is individuals in a medically supervised weight-loss, meal replacement program. Meal replacement programs (MRP) offer positive, minimal-choice, healthy results. Yet, MRP are controversial, receiving criticism for being unnatural, nutritionally inadequate, and difficult to maintain. People undertaking MRP are likely challenged in their environments as individuals around them react to the lifestyle change.
