NLA consensus statement

NLA issues statement on lipid and cholesterol levels

Landmark consensus statement representing the most comprehensive review of this topic to date

The National Lipid Association (NLA) has issued a consensus statement, ‘Obesity, adiposity, and dyslipidemia: A consensus statement from the National Lipid Association’, on the impact of disturbances in calorie balance on lipid and cholesterol levels in the Journal of Clinical Lipidology.

“This consensus statement is an important step in better understanding the relationship between increased body fat, and the many adverse health issues it has on patients,” said Dr Harold Bays, one of the authors of the statement. “Both clinicians and patients now have better scientific support for not only how excess calories and reduced physical activity may adversely affect body weight and heart disease risk, but also the degree by which interventions that help reduce body fat in overweight patients have the potential to improve certain types of cholesterol levels, and improve the health of patients.”

The statement provides the best scientific support to date on the connection between obesity and heart disease, and was published following NLA Consensus Conference held September 2012.

The statement describes how being overweight/obese and/or gaining weight and, specifically increasing body fat, may precipitate the development of “sick fat,” which is an important contributor to unhealthy levels of blood cholesterol and increased risk of cardiovascular disease.

They also describe how weight loss and reduction in body fat may improve blood lipid levels and decrease risk of heart disease.

The review is detailed and expansive in scope, with an emphasis on mechanisms accounting for insulin resistance and increased risk for diabetes, so often found in overweight and obese patients. The impact of body fat on specific lipid parameters is also explored, including triglyceride, high density lipoprotein cholesterol and low density lipoprotein cholesterol levels, as well as how abnormal levels of these blood lipids are improved by therapies directed towards assisting patients with weight reduction.

Highlighted therapies include an extensive review of nutritional intervention, physical activity, weight management, drug therapy and bariatric surgery.

These interventions not only improve the weight of patients, but also improve their metabolic health by beneficially impacting blood lipid and cholesterol levels with an accompanying reduction in risk for heart disease.

This landmark consensus statement representing the most comprehensive review of this topic to date validates what is known by clinicians and patients alike - that increases in body fat may worsen certain types of cholesterol / blood lipid levels.

The NLA is a nonprofit, multidisciplinary medical society focused on enhancing the practice of lipid management in clinical medicine. The NLA represents more than 3,500 members in the United States and provides continuing medical education for physicians and other healthcare professionals to advance professional development and attain certification in clinical lipidology.

The NLA's public health mission is to help reduce deaths related to high cholesterol, and the Association defines "clinical lipidology" as "a multidisciplinary branch of medicine focusing on lipid and lipoprotein metabolism and their associated disorders."

CO-authors of the study were Drs Peter P Toth, Penny Kris-Etherton, Nicola Abate, Louis Aronne, W Virgil Brown, J Michael Gonzalez-Campoy, Steven Jones, Rekha Kumar, Ralph La Forge and Varman Samuel.
