For prediabetics, many interventions focus on lifestyle changes and weight loss, but new research on periodic fasting has identified a biological process in the body that converts bad cholesterol in fat cells to energy, thus combating diabetes risk factors.
Researchers at the Intermountain Heart Institute at Intermountain Medical Center in Murray, Utah, noticed that after 10 to 12 hours of time fasting, the body starts scavenging for other sources of energy throughout the body to sustain itself. The body pulls LDL (bad) cholesterol from the fat cells and uses it as energy.
“Fasting has the potential to become an important diabetes intervention,” says Benjamin Horne, PhD, director of cardiovascular and genetic epidemiology at the Intermountain Medical Center Heart Institute and lead researcher on the study. “Though we’ve studied fasting and it’s health benefits for years, we didn’t know why fasting could provide the health benefits we observed related to the risk of diabetes.”
Researchers will present results of the study at the 2014 American Diabetes Association Scientific Sessions in San Francisco on Saturday, June 14, 2014, at 10:00AM, PDT.
Prediabetes means the amount of glucose, also called sugar, in the blood is higher than normal but not high enough to be called diabetes.
Prior research done by Dr. Horne and his team in 2011 focused on healthy people during one day of fasting and showed that routine, water-only fasting was associated with lower glucose levels and weight loss.
“When we studied the effects of fasting in apparently healthy people, cholesterol levels increased during the one-time 24-hour fast,” said Dr. Horne. “The changes that were most interesting or unexpected were all related to metabolic health and diabetes risk. Together with our prior studies that showed decades of routine fasting was associated with a lower risk of diabetes and coronary artery disease, this led us to think that fasting is most impactful for reducing the risk of diabetes and related metabolic problems.”
Due to the findings in 2011, Dr. Horne launched this new study to look at the effects of fasting in prediabetics over an extended period of time. The study participants were prediabetics, including men and women between the ages of 30 and 69 with a least three metabolic risk factors. These risk factors include:
- A large waistline. This also is called abdominal obesity or “having an apple shape.”
- A high triglyceride level. Triglycerides are a type of fat found in the blood.
- A low HDL cholesterol level, the “good” cholesterol. A low HDL cholesterol level raises your risk for heart disease.
- High blood pressure. Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps blood.
- High fasting blood sugar. Mildly high blood sugar may be an early sign of diabetes.
