A nutrition-and-fitness that is high in unsaturated fat may be beneficial for the heart-health” target=”_blank”>cardiovascular health<, according to researchers.
In a Tuesday study published in the American Journal of Clinical Nutrition, Massachusetts-area authors randomly assigned 164 overweight and nutrition-and-fitness participants – predominantly women, ages 18 to 65 – to three weight-loss maintenance diets.

First, the participants were put on low-calorie diets that lowered their body weight by approximately 12%.
Next, in the testing phase, the participants were assigned to one of the diets in which 20%, 40% or 60% of calories came from carbs.
Protein, however, was kept steady at 20% for each diet; the remaining calories came from fat.

Lipoprotein(a) is a fatty particle in the blood that is linked to the development of heart disease.
In addition, the low-carb group saw lipoprotein insulin resistance (LPIR) scores – associated with incident Type 2 diabetes and premature coronary heart disease – drop, while those on the high-carb diet saw their scores rise.
Adiponectin levels – a protein hormone that plays a role in the development of insulin resistance – were increased.
“These results are broadly consistent with small feeding trials and behavioral studies that report improvements in multiple cardiometabolic outcomes on low-carbohydrate diets, including triglycerides, HDL cholesterol, glycemia, blood pressure, liver fat, and body weight,” the study said. “Effects on these risk factors could mediate, to some degree, the associations between glycemic load and risk of CVD events and mortality observed in a recent 20-country study.”

In conclusion, the study said that restricting carbs in one’s diet might lower the risk of cardiovascular disease independent of body weight.
It’s a possibility the authors said warrants further study and major multicentered trials.

What’s the best diet to choose according to the study’s parameters?
A Mediterranean-style low-carb diet, with an emphasis on unsaturated fats, is the best diet to choose according to the study’s parameters, as it targets both elevated LDL cholesterol and insulin-resistant dyslipoproteinemia.
