It's sad but true that America is the unhealthiest industrialized nation in the world. This Quick Study explains how we got there and how Atkins addresses the current epidemics of obesity, diabetes and heart disease.   MORE

Study out of the University of Pennsylvania, Philadelphia Veterans Affairs Medical Center and Drexel University College of Medicine compared the effects of a low-carbohydrate diet and a low fat diet on lipoprotein subfractions and inflammation on severely obese subjects.

 “Syndrome X, also known as the ‘insulin resistance syndrome,’ may be the surest route to a heart attack. It is as powerful a predictor of coronary heart disease as elevated LDL ‘bad’ cholesterol, if not more so.”—Dr. Gerald Reaven   MORE
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.

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).

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.

Fortunately, the Atkins Nutritional Approach™ offers the key to unlatch the trap—in the form of the biochemical process called lipolysis.

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.

Study out of Harvard University recruited twenty-one participants who were randomly assigned to separate diets for 12 weeks: a low fat diet and two different low carbohydrate diets, one allowing 300 more calories a day.   MORE

Once you've reached your goal weight, know that if you regain some pounds, returning briefly to an earlier phase can banish the problem.

Study out of University of Pennsylvania School of Medicine, University of Colorado Health Sciences Center and Washington University School of Medicine randomly assigned participants to either a low-carbohydrate, high-protein, high-fat diet or a low-calorie, high-carbohydrate, low-fat diet.   MORE

What do we mean when we say “Results not typical. Individual results will vary”?

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.

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.   MORE
Study out of the Veterans Administration Hospital assigned obese adults randomly to either a restricted carbohydrate diet or a low fat diet.   MORE
The history of science is filled with brilliant discoveries that were not warmly welcomed. In fact, it’s almost a truism that it takes about 50 years before a revolutionary concept is truly accepted by the mainstream, particularly when that concept challenges prevailing dogma.   MORE
Too much of this hormone may well be the reason you can't lose weight.   MORE
Study out of the University of Cincinnati assigned obese, healthy women to follow either a low carbohydrate or low fat diet for four months. Both groups were given nutrition counseling and were instructed to record energy expenditure using a pedometer.   MORE
Two brand new studies offer some interesting insights on how people lose weight as well as how to overcome the challenge of keeping it off successfully.   MORE

Study out of the University of Cincinnati instructed obese women to follow either a low fat, calorie restricted diet or a low carbohydrate diet for six months.

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.   MORE
METABOLIC SYNDROME AND HEART DISEASE: WHAT’S THE CONNECTION?
Are you looking a little apple-shaped these days? You may have never heard of metabolic syndrome but if your waist is bigger than your hips, you might have it. And the condition is intimately linked to heart disease as well as diabetes. Find out what it is, how to prevent it and—if you already have it—how to treat it.
