Summary:
Untested alternative weight loss diets, such as very low carbohydrate diets, have unsubstantiated efficacy and the potential to adversely affect cardiovascular risk factors. Therefore, we designed a randomized, controlled trial to determine the effects of a very low carbohydrate diet on body composition and cardiovascular risk factors. Subjects were randomized to 6 months of either an ad libitum very low carbohydrate diet or a calorie-restricted diet with 30% of the calories as fat. Anthropometric and metabolic measures were assessed at baseline, 3 months, and 6 months. Fifty-three healthy, obese female volunteers (mean body mass index, 33.6 +/- 0.3 kg/m(2)) were randomized; 42 (79%) completed the trial. Women on both diets reduced calorie consumption by comparable amounts at 3 and 6 months. The very low carbohydrate diet group lost more weight (8.5 +/- 1.0 vs. 3.9 +/- 1.0 kg; P < 0.001) and more body fat (4.8 +/- 0.67 vs. 2.0 +/- 0.75 kg; P < 0.01) than the low fat diet group. Mean levels of blood pressure, lipids, fasting glucose, and insulin were within normal ranges in both groups at baseline. Although all of these parameters improved over the course of the study, there were no differences observed between the two diet groups at 3 or 6 months. beta- Hydroxybutyrate increased significantly in the very low carbohydrate group at 3 months (P = 0.001). Based on these data, a very low carbohydrate diet is more effective than a low fat diet for short-term weight loss and, over 6 months, is not associated with deleterious effects on important cardiovascular risk factors in healthy women.

Any of you guys find it humorous that Dr. Atkins was clinically defined as obese when he died? The paper said he died at 260 soune odd pounds.

Dr. Atkins was in a coma and being pumped full of steroids in an attempt to save his life from his fall. It is no wonder that he gained 70 lbs during this period. He was 190 before the fall.

Remember the first rule of evaluation, consider the source. The "doctor" that released the autopsy results is a vegetarian who unethically (and probably illegally) requested medical records. Note, as a doctor you can request medical records only if you are a physician on the case, this doctor wasn't and misrepresented him self to get them. His goal, as a militant vegetarian belonging to a militant veggie group, was to create bad press for Atkins so that people would eat fewer animal products.

Mike, I heard on the radio this morning, that these vegy people are connected to PETA.

I'm not a fan of the Atkins diet, probably because I love my carbs, but I dislike the radical PETA people more.

Summary:
In this clinical trial, researchers set out to determine the short-term effects of substituting protein for carbohydrate in the diets of adults with high cholesterol levels. Ten subjects (4 men, 6 women) with moderately high cholesterol levels were randomly assigned to follow a high-protein (average 23% calories from protein, 24% fat, 53% carbohydrate) or low-protein diet (average 11% calories from protein, 24% fat, 65% carbohydrate) for four to five weeks. After that time, subjects switched to the other diet for an additional four to five weeks. Both diets had the same total amount of calories. When participants followed the high-protein diet, average HDL (“good”) cholesterol levels were 12% higher, mean total cholesterol was 6.5% lower, mean LDL (“bad”) cholesterol was 6.4% lower and mean total triglycerides were 23% lower than when subjects followed the low-protein diet. The authors concluded that substituting protein for carbohydrate could be useful in preventing or retarding the progression of coronary heart diseas

Summary:


Carbohydrate-induced hypertriglyceridemia, a well-described clinical syndrome, may be a contributing factor to the increasing prevalence of metabolic syndrome, which consists of abdominal obesity, high triglycerides, low HDL-cholesterol, high blood pressure, and high fasting serum glucose.  This study was conducted to determine the effects of a low carbohydrate ketogenic diet program on body weight and serum lipids in an outpatient setting.  This two-arm randomized controlled trial compared a low-carbohydrate ketogenic diet (LC) (<20 grams/day "Atkins type") and nutritional supplements (including fish, borage, and flaxseed oil) to a low-fat, low-calorie diet (LF) overweight/obese, hyperlipidemic (LDL>130mg/dl or triglycerides>200mg/dl) otherwise healthy volunteers motivated to lose weight for six-months.  Subjects attended group meetings biweekly for 3 months, then monthly.  Outcomes were body mass index (BMI) and serum lipids using an NMR lipoprotein subclass technique.  The mean age of subjects was 46 years, the mean baseline BMI was 34.5kg/m2, 75% were female, 80% were Caucasian. The weight loss over six months was 13.8% for LC (n=36) and 8.8% for LF (n=27). The reduction in VLDL for was greater for LC than LF (-49% vs. -17%, p<0.01). Both groups had a 73% reduction in small LDL, an increase in LDL diameter (+5% for LC, and +1% for LF) and a decrease in LDL particle concentration (-7% for LC -16% for LF). The increase in large LDL was greater for LC (+53%) than low LF (+2%), p<0.01). The LC group had a 1% decrease in HDL-C, the LC group had an 8% increase in HDL-C. The reduction in TG/HDL ratio was greater for LC than LF(-53% vs. -6%, p<0.01). Diet , nutritional supplement or exercise compliance  could not account for these changes. A low-carbohydrate ketogenic with fish, borage and flaxseed oil supplementation led to weight loss, a reduction in VLDL, and increase in HDL-cholesterol and a change from small to large LDL cholesterol. Due to these favorable effects on weight, VLDL and HDL, this approach may be useful to treat the metabolic syndrome.

Stats 101...P=0.001 means the difference noted is extremely unlikely to be just natural variation between the two groups caused the difference noted.

Losing weight - eat less, burn more, or both. Exercise burns more, but so does a metabolism bump and, for some people, high protein/low carb gives that bump.

I see people noting Atkins as "eat all you want". That's a misrepresentation. It advocates balance of diet, exercise and controlling carb levels and not eating processed and unnatural stuff. It's when someone abuses the concept and eat's all they can of meat, cheese, etc is when they'll get in trouble.

That said, I believe weight loss must be custom to your specific metabolism. Some fit Atkin's some fit others. Example, high protein/low carb works extremely well for me, not so great for the wife. I can do Atkin's (or south beach or any of those that are essentially the same diet), she's more effective with strictly calorie control and exercise.

It's about the individual. So I don't see how you guys are sitting and bashing/defending a particular diet since one size never fits all.

Summary:


The following information is available at Pub Med and was not written by Atkins professionals.


To determine the effect of a 6-month very low carbohydrate diet program on body weight and other metabolic parameters.Fifty-one overweight or obese healthy volunteers who wanted to lose weight were placed on a very low carbohydrate diet (<25 g/d), with no limit on caloric intake. They also received nutritional supplementation and recommendations about exercise, and attended group meetings at a research clinic. The outcomes were body weight, body mass index, percentage of body fat (estimated by skinfold thickness), serum chemistry and lipid values, 24-hour urine measurements, and subjective adverse effects.Forty-one (80%) of the 51 subjects attended visits through 6 months. In these subjects, the mean (+/- SD) body weight decreased 10.3% +/- 5.9% (P <0.001) from baseline to 6 months (body weight reduction of 9.0 +/- 5.3 kg and body mass index reduction of 3.2 +/- 1.9 kg/m(2)). The mean percentage of body weight that was fat decreased 2.9% +/- 3.2% from baseline to 6 months (P <0.001). The mean serum bicarbonate level decreased 2 +/- 2.4 mmol/L (P <0.001) and blood urea nitrogen level increased 2 +/- 4 mg/dL (P <0.001). Serum total cholesterol level decreased 11 +/- 26 mg/dL (P = 0.006), low-density lipoprotein cholesterol level decreased 10 +/- 25 mg/dL (P = 0.01), triglyceride level decreased 56 +/- 45 mg/dL (P <0.001), high-density lipoprotein (HDL) cholesterol level increased 10 +/- 8 mg/dL (P <0.001), and the cholesterol/HDL cholesterol ratio decreased 0.9 +/- 0.6 units (P <0.001). There were no serious adverse effects, but the possibility of adverse effects in the 10 subjects who did not adhere to the program cannot be eliminated.A very low carbohydrate diet program led to sustained weight loss during a 6-month period. Further controlled research is warranted.

Summary:
The purpose of this study was to analyze the effect of increasing protein versus increasing carbohydrate on weight loss in obese individuals. Sixty-five overweight and obese subjects were assigned to either a high-carbohydrate diet (58% carbohydrate, 30% fat, 12% protein) or a high-protein diet (45% carbohydrate, 30% fat, 25% protein) for a period of six months, with most of the measurements taken after three months. Weight loss after three months was greater in the high-protein group than the high-carbohydrate group (16.5 pounds versus 11 pounds). Individuals on the high-protein diet also consumed less than those on the high-carbohydrate diet. More subjects lost more than 11 pounds in the high-protein group than in the high-carbohydrate group. In addition, a greater amount of body fat was lost by individuals in the high-protein group versus individuals in the high-carbohydrate group (12.8 pounds compared to 8.4 pounds). There were no differences in cholesterol levels between diet groups. However, the high-carbohydrate group experienced an increase in triglycerides in contrast to the decrease experienced by individuals in the high-protein group. Researchers concluded that the replacement of some dietary carbohydrate by protein improves mean weight loss and increases the proportion of subjects achieving a clinically relevant weight loss.

Weight Loss With High and Low Carbohydrate 1200 Kcal Diets in Free Living Women

Lean, M.E.J., Han, T.S., Prvan, T., et al., "Weight Loss With High and Low Carbohydrate 1200 Kcal Diets in Free Living Women," European Journal of Clinical Nutrition, 51(4), 1997, pages 243-248.


Summary:
This study examined the impact of high- and low-carbohydrate diets on weight loss and cardiovascular risk factors over six months. One hundred and ten women were put on either a high-carbohydrate (58%) or low-carbohydrate (35%) diet. Subjects were free from active disease but above normal body mass index. Both diets consisted of 1,200 calories per day. At the end of the study, researchers looked for changes in body weight, body mass index, body fat, cholesterol levels and blood pressure. Members of the high-carbohydrate group lost an average of 12 pounds, while those in the low-carbohydrate group lost an average of 15 pounds. Body composition measurements of the 46 post-menopausal women in this study revealed that those on the low-carbohydrate diet experienced significantly greater body fat loss at three and six months than those on the higher-carbohydrate diet. There were no significant changes in blood pressure between the two groups. Researchers noted significant reductions in total cholesterol, LDL ("bad") cholesterol, and HDL ("good") cholesterol on the high-carbohydrate diet, but not on the low carbohydrate diet. Triglyceride levels fell significantly in only the low-carbohydrate diet. It should be noted that the researchers considered the high-carbohydrate diet more beneficial than the low-carbohydrate diet due to its cholesterol-lowering effect. However, they failed to consider the detrimental effect this diet had on HDL ("good") cholesterol reduction. Medical professionals consider the ratio between total cholesterol and HDL cholesterol a more important predictor of disease risk than the value of total cholesterol. The low-carbohydrate group had a slight increase in HDL levels, which would be a more favorable adaptation.

Summary:
Claims about the merits or risks of carbohydrate (CHO) vs. protein for weight loss diets are extensive, yet the ideal ratio of dietary carbohydrate to protein for adult health and weight management remains unknown. This study examined the efficacy of two weight loss diets with modified CHO/protein ratios to change body composition and blood lipids in adult women. Women (n = 24; 45 to 56 y old) with body mass indices >26 kg/m(2) were assigned to either a CHO Group consuming a diet with a CHO/protein ratio of 3.5 (68 g protein/d) or a Protein Group with a ratio of 1.4 (125 g protein/d). Diets were isoenergetic, providing 7100 kJ/d, and similar amounts of fat ( approximately 50 g/d). After consuming the diets for 10 wk, the CHO Group lost 6.96 +/- 1.36 kg body weight and the Protein Group lost 7.53 +/- 1.44 kg. Weight loss in the Protein Group was partitioned to a significantly higher loss of fat/lean (6.3 +/- 1.2 g/g) compared with the CHO Group (3.8 +/- 0.9). Both groups had significant reductions in serum cholesterol ( approximately 10%), whereas the Protein Group also had significant reductions in triacylglycerols (TAG) (21%) and the ratio of TAG/HDL cholesterol (23%). Women in the CHO Group had higher insulin responses to meals and postprandial hypoglycemia, whereas women in the Protein Group reported greater satiety. This study demonstrates that increasing the proportion of protein to carbohydrate in the diet of adult women has positive effects on body composition, blood lipids, glucose homeostasis and satiety during weight loss

There are a lot of resources out there that will tell you that, from a medical stand point. One of them is this: http://www.atkinsdietalert.org/

While there may be many websites that dispute Atkins, there are more medical journals and scientific studies that proclaim low-carb diets.

Very-low-carbohydrate weight-loss diets revisited

ABSTRACT
Much scientific and anecdotal data demonstrate favorable metabolic responses to very-low-carbohydrate diets.We
believe that very-low-carbohydrate diets merit further study
for weight loss, and that criticisms of these diets lack
scientific evidence.

KEY POINTS
Most studies have found that people lose more weight on
very-low-carbohydrate diets than on standard weight-loss
diets.

Mechanisms of weight loss on these diets may go beyond
water loss and include suppression of appetite, increasing
the metabolic rate, decreasing metabolic efficiency, and
shunting of nutrients away from fat storage.

Weight loss is usually associated with small to moderate
reductions in lean tissue, but low-energy, very-lowcarbohydrate
diets may have a protein-sparing effect
compared with low-fat diets.

These diets may also have favorable effects on specific risk
factors for cardiovascular disease (eg, fasting and
postprandial triglyceride levels, high-density lipoprotein
levels, and low-density lipoprotein particle size).

You're citing a study that had only 8 people, no control group, and lasted only two weeks per phase? doesn't hardly sound reliable to me.

Want me to cite my source?

Here ya go: Dr. James Kenney, PhD, RD, FACN Nutrition Research Specialist.

I don't think that any dietitian would disagree with the statements that I made.

and i dont think anyone can disagree with demonstrated results, you might not like the method, or the risks involved with it, but the results speak for themselves in the cases I’m aware of....it may not be for everyone, and it certainly isnt for anyone lacking a disciplined approach, but having seen the effect in several people first hand, well......it worked for them, and yes all three i am still close to are still skinny 3 years later...they made the life style changes to maintain their 'new' body once they reached the goals they wanted from the Atkins diet..

again it’s a weight loss tool, not a way of life…there are certainly others and definitely others that are more cautious, but short of an amphetamine addiction I’ve never seen anyone lose so much weight so quickly….

its not for me..(i'm skinny anyway, exercise regularly and love pasta far to much) but i've seen it work for others....
