Low-Carb Diets May Improve Arterial Flexibility in Pre-Diabetic Women
Arterial stiffness is a natural process of aging that can be accelerated by obesity, insulin resistance, and metabolic syndrome. Arterial stiffness increases the risk of cardiovascular disease. A recent study suggests that low-carb diets may help women see mprovements in artery flexibility.
Participants in the study included 20 middle-aged people with a diagnosis of pre-diabetes. Pre-diabetes is characterized by having higher than normal blood sugar levels. The participants were given carb-restricted meals provided by a nutrition center for two weeks and then given meal planning instructions for another two weeks.
The researchers used pulse wave velocity to measure arterial stiffness. They found that the women had a reduced blood flow speed of 1 meter per second, which computes to a 6% reduction in pulse wave velocity. No changes were seen for the men.
In addition, over the four-week study period, the men lost 6.3% of their body weight, while the women lost to 4.4% of their body weight.
Researchers from the University of Missouri-Columbia conducted the study. It was published online ahead of print on May 10, 2018, in.
