WEDNESDAY, Jan. 2 (HealthDay News) -- Although obese patients on a very-low-carbohydrate, high-fat (VLCHF) diet and a high-carbohydrate, low-fat (HCLF) diet experience similar degrees of weight loss, the HCLF diet results in a more favorable blood lipid profile, according to a study published in the Jan. 1 issue of the Journal of the American College of Cardiology.
Jeannie Tay, and colleagues from the Commonwealth Scientific and Industrial Research Organisation - Human Nutrition in Adelaide, Australia, randomly assigned 88 abdominally obese adults to an isocaloric VLCHF diet or an HCLF diet for 24 weeks.
The researchers found that both groups had similar reductions in weight, blood pressure, C-reactive protein, fasting glucose and insulin. Triacylglycerol levels decreased the most and high-density lipoprotein cholesterol levels increased the most with the VLCHF diet. Low-density lipoprotein cholesterol levels decreased with the HCLF diet and were unchanged with the VLCHF diet, although there was a high degree of individual variability with the VLCHF diet.
"Under isocaloric conditions, VLCHF and HCLF diets result in similar weight loss," Tay and colleagues conclude. "Overall, although both diets had similar improvements for a number of metabolic risk markers, an HCLF diet had more favorable effects on the blood lipid profile."
