Weight Loss with a Low-Carbohydrate, Mediterranean or Low-Fat diet.
In this two-year trial, 322 moderately obese subjects (86 percent of them male, with a mean age of 52 years and a mean body-mass index of 31) to one of three diets: low-fat, restricted-calorie; Mediterranean, restricted-calorie; or low-carbohydrate, non-restricted-calorie.

Comparison of the Atkins, Ornish, Weight Watchers, and Zone Diets for Weight Loss and Heart Disease Risk Reduction: a Randomized Trial
A single-center randomized trial at an academic medical center in Boston, Mass., studied the health effects of popular diets in overweight or obese adults (mean body mass index of 35; range, 27-42) aged 22 to 72 years with known hypertension, poor cholesterol profiles or high fasting blood sugar. A total of 160 participants were randomly assigned to either the Atkins, Zone, Weight Watchers or Ornish diet groups.

Short-Term Effects of Severe Dietary Carbohydrate-Restriction Advice in Type 2 Diabetes--a Randomized Controlled Trial
This study sought to examine the effects of a three-month program of 102 patients with poorly controlled type 2 diabetes to following dietary advice to restrict carbohydrate intake compared with following advice to reduce portions and restrict fat. Weight loss was greater in the low-carbohydrate group.

Effects of Dietary Carbohydrate Restriction Versus Low-Fat Diet on Flow-Mediated Dilation
Previously the authors of this study reported that a carbohydrate-restricted diet improved many of the traditional markers associated with metabolic syndrome and cardiovascular risk when compared with a low-fat diet. In this study, they extend their work to address the concerns of fasting and post-meal vascular function in 40 overweight men and women with moderately high triglycerides who were randomly assigned to consume either a low-fat diet or a low-carbohydrate diet.

Meta-Analysis of Prospective Cohort Studies Evaluating the Association of Saturated Fat with Cardiovascular Disease
The objective of this meta-analysis was to summarize the evidence related to the association of dietary saturated fat with risk of coronary heart disease, stroke and cardiovascular disease (coronary heart disease inclusive of stroke) in prospective epidemiologic studies.

Saturated Fat, Carbohydrate, and Cardiovascular Disease
Researchers at the Harvard School of Public Health reported that the evidence that supports a reduction in saturated fat intake must be evaluated in the context of replacement by other macronutrients. An independent association of saturated fat intake with cardiovascular disease risk has not been consistently shown in prospective epidemiologic studies, although some have provided evidence of an increased risk in young individuals and in women. However, replacement with a higher carbohydrate intake, particularly refined carbohydrate, can exacerbate the atherogenic dyslipidemia associated with insulin resistance and obesity that includes increased triglycerides, small LDL particles and reduced HDL cholesterol.

Effects of a carbohydrate-restricted diet on emerging plasma markers for cardiovascular disease
Summary:
Abstract (provisional)
Background
Increasing evidence supports carbohydrate restricted diets (CRD) for weight loss and improvement in traditional markers for cardiovascular disease (CVD); less is known regarding emerging CVD risk factors. We previously reported that a weight loss intervention based on a CRD (% carbohydrate:fat:protein = 13:60:27) led to a mean weight loss of 7.5 kg and a 20% reduction of abdominal fat in 29 overweight men. This group showed reduction in plasma LDL-cholesterol and triglycerides and elevations in HDL-cholesterol as well as reductions in large and medium VLDL particles and increases in LDL particle size. In this study we report on the effect of this intervention with and without fiber supplementation on plasma homocysteine, lipoprotein (a) [Lp(a)], C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-alpha).
