TYPE 2 DIABETES TREATMENTS SHOULD FOCUS ON WEIGHT LOSS





An international panel of experts from four renowned diabetes research centers, including U.T. Southwestern Medical Center, has reviewed current literature and recommends a pivotal change in the treatment of Type 2 diabetes to focus on obesity first and glucose control second.

"It's known that obesity contributes to the progression of diabetes. What's new is that instead of focusing exclusively on lowering blood sugar, we recommend the primary approach to the treatment of Type 2 diabetes be on the treatment of obesity," said first author Ildiko Lingvay, M.D., M.P.H., M.S.C.S.

The researchers state that dropping 15% or more of body weight can have a disease-modifying effect in Type 2 diabetes, an outcome that is unattainable by any other glucose-lowering intervention. The new focus would require updating current treatment guidelines and providing significant provider education, they note. The panel's recommendations are published in The Lancet and were presented at the European Association for the Study of Diabetes conference.

The current approach to diabetes treatment relies on clinical studies from the 1980s, which found that lowering blood sugar results in fewer complications from the disease. These early results supported treating blood glucose as the critical target, said Dr. Lingvay.

"The problem with this approach is that it doesn't address the core problem and does not offer an opportunity to reverse the disease," said Dr. Lingvay, who leads an active clinical research program in the Division of Endocrinology at U.T. Southwestern. "We propose using a proactive approach. Let's address the cause of the disease -- obesity."


According to the American Diabetes Association, Type 2 diabetes is a progressive disease caused by obesity or abnormalities in metabolism. More than 10% of the U.S. population has diabetes, and 1.5 million more are diagnosed each year.

Bariatric surgery can be effective for patients with obesity, but not all patients have access to this option. "It's hard to achieve sustained weight loss. Most lifestyle interventions result in progressive weight loss over six months, followed by a plateau and weight regain over one to three years," added Dr. Lingvay. "New weight loss medications and those in the pipeline will help patients succeed in managing their weight over the long term."

The researchers also stressed the importance of advocating for insurance coverage that supports the treatment of obesity and diabetes and working in public health to increase access to care and reduce disparities.

The authors' disclosures are listed in the manuscript.

PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY

  PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY Building on prior studies with healthy-weight participants, the new research includes different body sizes.         New research indicates that weight influences how and when bodies burn energy. An Oregon Health & Science University study published in the journal  Obesity  found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who are obese spend more energy during the night when most people sleep. The study also found that during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar. "It was surprising to learn how dramatically the timing of when our bodies burn energy differed in those with obesity," said the study's first author, Andrew McHill, Ph.D., an assistant professor at the OHSU School of Nursing and the Oregon Institute of ...

WHAT CAUSES ITCHING, AND WHAT STOPS IT?

  WHAT CAUSES ITCHING, AND WHAT STOPS IT?         It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a severe health problem. How does the body know when to stop? Scientists at UC San Francisco are getting close to an answer. In a breakthrough that could transform how doctors treat conditions from eczema to allergies, they have discovered a feedback loop centered on a single immune protein called IL-31 that causes the urge to itch and dials back nearby inflammation. The findings, published on October 13th in  Science Immunology , lay the groundwork for a new generation of drugs that interact more intelligently with the body's innate self-regulating ability. Previous approaches suggested that IL-31 signals itch and promotes skin inflammation. However, the UCSF team discovered that nerve cells, or neurons, that respond to IL-31, triggering a scratch, also prevent immune cells from overreacting and causing more ...

A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY

  A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY         In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it's well-known that eating less meat improves cardiovascular health, diet studies often need to be enhanced by genetic differences, upbringing, and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households and reported similar lifestyles. "Not only did this study provide a groundbreaking way to assert that a vegan diet is healthier than the conventional omnivore diet, but the twins were also a riot to work with," said Christopher Gardner, Ph.D., the Rehnborg Farquhar Professor and a professor of medicine. "They dressed the same, they talked the same, and they had a banter ...
