People who are overweight and obese and are looking to shed some pounds can go ahead with low-carbohydrate and high-fat-diets, as these diets don't cause harm to arteries. suggest studies.
"Overweight and obese people appear to really have options when choosing a weight-loss program, including a low-carb diet and even if it means eating more fat," says the studies'' lead investigator exercise physiologists Kerry Stewart, Ed.D.Stewart, a professor of medicine and director of clinical and research exercie physiology at the Johns Hopkins University School of Medicine and its Heart and Vascular Institute, says his team''s latest analysis is believed to be the first direct comparison of either kind of diet on the effects to vascular health, using the real-life context of 46 people trying to lose weight through diet and moderate exercise . The research was prompted by concerns from people who wanted to include one of the low-carb, high-fat diets, such as Atkins , South Beach and Zone, as part of their weight-loss program, but were wary of the diets'' higher fat content.
In the first study, scheduled to be presented June 3 at the annual meeting of the American College of Sports Medicine in Denver, the Hopkins team studied 23 men and women, weighing on average 218 pounds and participating in a six-month weight-loss program that consisted of moderate aerobic exercise and lifting weights, plus a diet made up of no more than 30 percent of calories from carbs, such as pastas, breads and sugary fruits. As much as 40 percent of their diet was made up of fats coming from meat, dairy products and nuts. This low-carb group showed no change after shedding 10 pounds in two key measures of vascular health: finger tip tests of how fast the inner vessel lining in the arteries in the lower arm relaxes after blood flow has been constrained and restored in the upper arm (the so-called reactive hyperemia index of endothelial function), and the augmentation index, a pulse-wave analysis of arterial stiffness.
