The end of 8 weeks
Well my 8 weeks is up. I managed to get to 165lbs and 35.5" waist. I'm going to keep going slow until I get my waist measurement down where I want it. This picture sucks, but Zeus looks funny.
I didn't get Mark Sission lean yet.

Dr. Cordain's response to the US news report
I have copied and pasted this from Robb Wolf's site:
So…I’ve received a ton of emails, FB pings and twitter inquiries about the recent US News piece that ranked Paleo dead last in a list that included SlimFast, MediFast and Weight Watchers as contenders in this Diet Battle Royale. The whole thing is as sad as it is funny, but the most important feature to all of this is the “experts” consulted for this piece did not address the science.
At all.
I’m still working on the Kidney piece, but Prof. Cordain has put together a great response. More are in the works and we are working to have an opportunity for an official rebuttal or debate with the “experts” on that piece. The “why” behind this piece is pretty obvious: with no governmental support, no reality show, no acceptance amongst most departments of Nutritional ”Science” the Paleo concept is exploding.
Please copy Prof. Cordain’s response to your blog, tweet it and Facebook it.
Hi Doc,
I’m not sure if you’ve seen this or not, but US News ranked Paleo last of 20 diets claiming a lack of scientific evidence and no-long term weight maintenance guidelines. I’m not sure if you’d be interested in defending it or not, but if you’d be willing to provide specific refutations of their claims, I’d like to write a response piece for the Colorado State University Collegian to run next Wednesday, my deadline is Saturday.
Thanks.

Hi Seth,
Good to hear from you and many thanks for your continued support of the Paleo Diet. I hadn’t seen this piece, but I appreciate that you have brought it to my attention. It is obvious that whoever wrote this piece did not do their homework and has not read the peer review scientific papers which have examined contemporary diets based upon the Paleolithic food groups which shaped the genomes of our ancestors. Accordingly the writer’s conclusions are erroneous and misleading. I feel strongly that it is necessary to point out these errors and make this information known to a much wider audience than those reached by the readers of the U.S. News and World Report. You have my permission to syndicate my response and or your write up for the CSU Collegian to any of the major news services including AP and UPI. Additionally, I will copy a number of colleagues and scientists worldwide with this message to ensure that it will be widely circulated on the web, blogs and chat groups.
The writer of this article suggests that the Paleo Diet has only been scientifically tested in “one tiny study”. This quote is incorrect as five studies (1-7); four since 2007, have experimentally tested contemporary versions of ancestral human diets and have found them to be superior to Mediterranean diets, diabetic diets and typical western diets in regards to weight loss, cardiovascular disease risk factors and risk factors for type 2 diabetes.
The first study to experimentally test diets devoid of grains, dairy and processed foods was performed by Dr. Kerin O’Dea at the University of Melbourne and published in the Journal, Diabetes in 1984 (6). In this study Dr. O’Dea gathered together 10 middle aged Australian Aborigines who had been born in the “Outback”. They had lived their early days primarily as hunter gatherers until they had no choice but to finally settle into a rural community with access to western goods. Predictably, all ten subjects eventually became overweight and developed type 2 diabetes as they adopted western sedentary lifestyles in the community of Mowwanjum in the northern Kimberley region of Western Australia. However, inherent in their upbringing was the knowledge to live and survive in this seemingly desolate land without any of the trappings of the modern world.
Dr. O’Dea requested these 10 middle aged subjects to revert to their former lives as hunter gatherers for a seven week period. All agreed and traveled back into the isolated land from which they originated. Their daily sustenance came only from native foods that could be foraged, hunted or gathered. Instead of white bread, corn, sugar, powdered milk and canned foods, they began to eat the traditional fresh foods of their ancestral past: kangaroos, birds, crocodiles, turtles, shellfish, yams, figs, yabbies (freshwater crayfish), freshwater bream and bush honey. At the experiment’s conclusion, the results were spectacular, but not altogether unexpected given what known about Paleo diets, even then. The average weight loss in the group was 16.5 lbs; blood cholesterol dropped by 12 % and triglycerides were reduced by a whopping 72 %. Insulin and glucose metabolism became normal, and their diabetes effectively disappeared.
The first recent study to experimentally test contemporary Paleo diets was published in 2007 (5). Dr. Lindeberg and associates placed 29 patients with type 2 diabetes and heart disease on either a Paleo diet or a Mediterranean diet based upon whole grains, low-fat dairy products, vegetables, fruits, fish, oils, and margarines. Note that the Paleo diet excludes grains, dairy products and margarines while encouraging greater consumption of meat and fish. After 12 weeks on either diet blood glucose tolerance (a risk factor for heart disease) improved in both groups, but was better in the Paleo dieters. In a 2010 follow-up publication, of this same experiment the Paleo diet was shown to be more satiating on a calorie by calorie basis than the Mediterranean diet because it caused greater changes in leptin, a hormone which regulates appetite and body weight.
In the second modern study (2008) of Paleo Diets, Dr. Osterdahl and co-workers (7) put 14 healthy subjects on a Paleo diet. After only three weeks the subjects lost weight, reduced their waist size and experienced significant reductions in blood pressure, and plasminogen activator inhibitor (a substance in blood which promotes clotting and accelerates artery clogging). Because no control group was employed in this study, some scientists would argue that the beneficial changes might not necessarily be due to the Paleo diet. However, a better controlled more recent experiments showed similar results.
In 2009, Dr. Frasetto and co-workers (1) put nine inactive subjects on a Paleo diet for just 10 days. In this experiment, the Paleo diet was exactly matched in calories with the subjects’ usual diet. Anytime people eat diets that are calorically reduced, no matter what foods are involved, they exhibit beneficial health effects. So the beauty of this experiment was that any therapeutic changes in the subjects’ health could not be credited to reductions in calories, but rather to changes in the types of food eaten. While on the Paleo diet either eight or all nine participants experienced improvements in blood pressure, arterial function, insulin, total cholesterol, LDL cholesterol and triglycerides. What is striking about this experiment is how rapidly so many markers of health improved, and that they occurred in every single patient.
In an even more convincing recent (2009) experiment, Dr. Lindeberg and colleagues (2) compared the effects of a Paleo diet to a diabetes diet generally recommended for patients with type 2 diabetes. The diabetes diet was intended to reduce total fat by increasing whole grain bread and cereals, low fat dairy products, fruits and vegetables while restricting animal foods. In contrast, the Paleo diet was lower in cereals, dairy products, potatoes, beans, and bakery foods but higher in fruits, vegetables, meat, and eggs compared to the diabetes diet. The strength of this experiment was its cross over design in which all 13 diabetes patients first ate one diet for three months and then crossed over and ate the other diet for three months. Compared to the diabetes diet, the Paleo diet resulted in improved weight loss, waist size, blood pressure, HDL cholesterol, triglycerides, blood glucose and hemoglobin A1c (a marker for long term blood glucose control). This experiment represents the most powerful example to date of the Paleo diet’s effectiveness in treating people with serious health problems.
So, now that I have summarized the experimental evidence supporting the health and weight loss benefits of Paleo Diets, I would like to directly respond to the errors in the U.S. News and World Report article.
1. “Will you lose weight? No way to tell.”
Obviously, the author of this article did not read either the study by O’Dea (6) or the more powerful three month crossover experiment by Jonsson and colleagues (9) which demonstrated the superior weight loss potential of high protein, low glycemic load Paleo diets. Similar results of high protein, low glycemic load diets have recently been reported in the largest randomized controlled trials ever undertaken in both adults and children.
A 2010 randomized trial involving 773 subjects and published in the New England Journal of Medicine (8) confirmed that high protein, low glycemic index diets were the most effective strategy to keep weight off. The same beneficial effects of high protein, low glycemic index diets were dramatically demonstrated in largest nutritional trial, The DiOGenes Study (9), ever conducted in a sample of 827 children. Children assigned to low protein, high glycemic diets became significantly fatter over the 6 month experiment, whereas those overweight and obese children assigned to the high protein, low glycemic nutritional plan lost significant weight.
2. “Does it have cardiovascular benefits? Unknown.”
This comment shows just how uninformed this writer really is. Clearly, this person hasn’t read the following papers (1 – 6) which unequivocally show the therapeutic effects of Paleo Diets upon cardiovascular risk factors.
“And all that fat would worry most experts.”
This statement represents a “scare tactic” unsubstantiated by the data. As I, and almost the entire nutritional community, have previously pointed out, it is not the quantity of fat which increases the risk for cardiovascular disease or cancer, or any other health problem, but rather the quality. Contemporary Paleo Diets contain high concentrations of healthful omega 3 fatty acids, monounsaturated fatty acids and long chain polyunsaturated fatty acids that actually reduce the risk for chronic disease (10-18).
3. “Can it prevent or control diabetes? Unknown.”
Here is another example of irresponsible and biased journalism which doesn’t let the facts speak for themselves. Obviously, the author did not read the study by O’dea (6) or Jonsson et al. (2) which showed dramatic improvements in type 2 diabetics consuming Paleo diets.
“but most diabetes experts recommend a diet that includes whole grains and dairy products.”
If the truth be known, in a randomized controlled trial, 24 8-y-old boys were asked to take 53 g of protein as milk or meat daily (19). After only 7 days on the high milk diet, the boys became insulin resistant. This is a condition that precedes the development of type 2 diabetes. In contrast, In the meat-group, there was no increase in insulin and insulin resistance. Further, in the Jonsson et al. study (2) milk and grain free diets were shown to have superior results in improving disease symptoms in type 2 diabetics.
4. “Are there health risks? Possibly. By shunning dairy and grains, you’re at risk of missing out on a lot of nutrients.”
Once again, this statement shows the writer’s ignorance and blatant disregard for the facts. Because contemporary ancestral diets exclude processed foods, dairy and grains, they are actually more nutrient (vitamins, minerals and phytochemicals) dense than government recommended diets such as the food pyramid. I have pointed out these facts in a paper I published in the American Journal of Nutrition in 2005 (13) along with another paper in which I analyzed the nutrient content of modern day Paleo diets (12 ). Most nutritionists are aware that processed foods made with refined grains, sugars and vegetable oils have low concentrations of vitamins and minerals, but few realized that dairy products and whole grains contain significantly lower concentrations of the 13 vitamins and minerals most lacking in the U.S. diet compared to lean meats, fish and fresh fruit and vegetables (12, 13).
“Also, if you’re not careful about making lean meat choices, you’ll quickly ratchet up your risk for heart problems” .
Actually, the most recent comprehensive meta analyses do not show fresh meat consumption whether fat or lean to be a significant risk factor for cardiovascular disease (20-25), only processed meats such as salami, bologna, bacon and sausages (20).

I have uploaded My Primal Plate design to Zazzle, didn't sell so I guess they deleted it.

My Primal Plate
The Food Plate is replacing the Food Pyramid. So I decided to take the Primal Blueprint Pyramid and convert it to a plate. I want to keep up with the times you know. So here it is...My Primal Plate.

Calorie counting, or how to piss people off.
Here's another answer I posted on the MDA forum.
I think of two different ways to count calories. The CW way of counting calories and the Primal way of counting calories. The big difference in the two ways is exercise. The CW way of counting calories is to use a formula to establish your caloric needs. You weigh and measure your food intake so you stay under your needs. You also do cardio to increase the number of calories you burn. But the problem is cardio increases your need for carbs. If you are doing very low carb your body will break down protein to make the carbs you need, especially bad if you are not consuming enough protein. This is the way we head off into metabolic derangement via the carb/cardio pathway. The Primal way of calorie counting is a little different. First We use the formula to get our caloric needs just like we did for the CW of calorie counting. We decide how fast we want to lose weight, like 1 lbs per week. We then consume that amount of calories. Such as, my caloric needs are 2,000 calories, I want to lose a lb a week which is 3,600 calories, or a 500 calorie a day deficet. So I eat 1,500 calories a day. I do not try to lose any calories through cardio activity. I focus instead on building muscle through lifting heavy things and sprinting. I also burn calories by doing low level activity, such as walking, cleaning the house, and work in general. I don't sit to do anything for very long. Building muscle and doing low level activities burns fat, not carbs.
Yes, for the maintaining weight you need 1 gram of protein per body weight, but for changing your body composition you will want to increase your protein consumption to something over that. If you are trying to lose fat and build muscle you need more like 1.5 grams per pound of lean body weigh, or 1 gram per pound of body weigh. It would look like this: I weigh 170 lbs. Let's say I have 12% body fat. So I have 20.4 lbs of fat and 149.6 lbs of lean mass. So I decide I want to maintain my weight of 170 lbs and I want my body fat to be at 8%. That would put me at 13.6 lbs of fat and 156.4 lbs of lean mass. I think I would need at a very minimum 157 grams of protein a day. I believe 170 grams would probably be better. It probably wouldn't hurt to eat 1.5 grams x 157 = 235.5 grams. The key to remember is this; Focus on changing your body composition through building muscle.
Seems like people really get mad when you mention calorie counting and with good reason. CW calorie counting got them into metabolic derangement and now they not only can not loose weight, but they are gaining more weigh despite eating fewer calories. The only way out of the metabolic hell is the Primal Bluebprint/Paleo Diet. But people forgot about the exercise part of the program, or they focus too much on the food/diet aspect of the Blueprint. We don't reprogram our genes by diet alone. To reprogram our genes we need to follow the whole Primal Blueprint. Read or reread Mark Sission's guide to Primal Success.
Quick rundown of Mark Sission's Primal Blueprint:
1. Eat lots of animals, insects and plants.
2. Move around a lot at a slow pace.
3. Lift heavy things.
4. Run really fast every once in a while.
5. Get lots of sleep.
6. Play.
7. Get some sunlight every day.
8. Avoid trauma.
9. Avoid poisonous things.
10. Use your mind.
