The Soft Science of Dietary Fat is a summary of an article in Science Magazine reporting that mainstream nutritional science has demonized dietary fat, yet 50 years and hundreds of millions of dollars of research have failed to prove that eating a low-fat diet will help you live longer. In fact, there are good reasons to believe high-carbohydrate diets may be even worse than high-fat diets. Here is the text from the original article by Gary Taubes.
Glassman reigns over this rampantly growing horde like a tribal chieftain. He now owns 100 percent of CrossFit and answers to no board of directors. Cash tends to race through the company. Until recently, the Glassmans each drew a salary of $750,000 a year; the travel and entertainment budget is in the tens of millions of dollars, and Glassman also spends money on what he calls "brand statements," including a set of $15,000 single-speed Swiss bikes and a $350,000, 1,500-horsepower fully customized 2011 Camaro convertible. (Before our visit to El Borracho, I followed him to a meeting to see about another "brand statement": custom luggage for his senior team, emblazoned with Uncle Pukie.)
It takes 30 days to push the reset button on your health and change your relationship with food. This is the concept behind Melissa and Dallas Hartwig’s Whole30 program. By eating non-processed whole foods and ditching grains, dairy, and sugar, you will reduce inflammation in your system, clear up your skin, and revitalize your energy stores. These are just a few of the benefits this program boasts.
I’m not going to say I didn’t have some pretty difficult moments. For example, don’t purchase an ice cream maker the day you start your Whole30 and let it sit in your entryway for 30 days to taunt you. I did that; it was dumb. Also, there were points in the program on those days when I felt off that I broke down or wanted to throw in the towel. Feeling bad on top of the normal Lyme symptoms wasn’t great, but I’m glad that I stuck it out.
As long as your salmon is low-mercury and wild (not farmed), you are doing your body good with this high- protein and fat combo. By consuming fat with protein, you give your body extra energy to break it down into amino acids – a key piece of daily digestion. This Whole30 recipe will set you up for smooth sailing the next day – so make it the night before your big morning meeting.
Jan Engvald has studied food and health thoroughly in the literature. In Unexpected facts on... food he shows that today's health advice (more or less unchanged for more than 30 years) is a direct cause to the increase in national diseases like coronary heart disease, stroke, cancer, obesity, adult-onset diabetes, allergy, eye diseases, etc. His findings are low-carb and high-fat, close to paleo, though he allows high fat dairy.
To make the curry sauce, melt the cooking fat in a saucepan over medium heat and swirl to coat the bottom of the pan. When the fat is hot, add the onion and cook, stirring, until translucent, 2 to 3 minutes. Add the garlic and stir until it becomes aromatic, about 30 seconds. Add the curry powder and stir for 15 to 20 seconds, taking care that the garlic and curry powder don’t burn. Add the tomatoes and simmer until thickened, about 5 minutes. Transfer the contents of the pan to a food processor or blender and puree until smooth. Pour into a mixing bowl and let cool. Mix in the coconut cream, salt, and pepper.
Research into the weight loss effects of the paleolithic diet has generally been of poor quality. One trial of obese postmenopausal women found improvements in weight and fat loss after six months, but the benefits had ceased by 24 months; side effects among participants included "weakness, diarrhea, and headaches". Any weight loss caused by the diet was merely the result of calorie restriction, rather than a special feature of the diet itself.
Paleo diets are based on a simple premise – if the cavemen didn’t eat it, you shouldn’t either. So long to refined sugar, dairy, legumes and grains (this is pre-agricultural revolution), and hello to meat, fish, poultry, fruits and veggies. The idea is that by eliminating modern-era foods like highly-processed carbs and dairy, you can avoid or control “diseases of civilization” like Type 2 diabetes and heart disease, and likely lose weight too. What you eat and how much depend on your goals or the specific program you’re on, if you choose to follow one. The high-protein diet is ranked poorly among U.S. News experts, who consider it too restrictive to be healthy or sustainable.
Eat generous amounts of saturated fats like coconut oil and butter or clarified butter. Beef tallow, lard and duck fat are also good, but only if they come from healthy and well-treated animals. Beef or lamb tallow is a better choice than lamb or duck fat. Olive, avocado and macadamia oil are also good fats to use in salads and to drizzle over food, but not for cooking. For more information, have a look at our beginner’s guide to Paleo and fat.
I have had to be gluten free for the last ten years, with my husband “playing” along, but not necessarily following closely. He has seen however a huge difference now – for the better, not having the gluten in his diet these past few weeks. In addition to taking out the alcohol, we were really worried about taking out the dairy. As much as we used to “live” on dairy – we are realizing that it has played a big part in our carrying extra, unnecessary pounds. These recipes are full and flavorful enough, that it has made it easier to jump in and follow the Whole30 plan without wanting to cheat. 50% OF THE WAY – WE CAN DO THIS!
Fresh fruits, fresh vegetables, fresh meat—the paleo diet is all about eating foods straight from the Earth just as our ancestors did. Those ancestors didn't have livestock or crops to call their own, so Cordain advises to go with grass-fed and organic varieties whenever possible to limit exposure to pesticides, antibiotics, and other chemicals that didn't exist back then. Research from Emory University suggests that Paleolithic people obtained about 35% of their calories from fats, 35% from carbohydrates, and 30% from protein.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
I personally struggle on a regular basis because I’m much more interested in heavy strength training than anything else – and I’m one of those people who really likes seeing very linear graphs and results to my training, and I do want to specialize. I have a very hard time creating workout plans because with CrossFit, you never know what’s coming next.
Following the paleo diet can be pricey. Inexpensive and healthy non-meat protein sources like soy and beans are off-limits, and a recent BMJ Open study shows that healthy meats like lean ground beef and boneless, skinless chicken breasts cost an average of 29 cents more per serving compared to less-healthy ones, such as high-fat ground beef and chicken drumsticks. Even switching from peanut butter to paleo-approved almond butter will cost you—it goes for up to $13 a jar.
What is a kipping pull-up? Isn’t that cheating? A kipping pull-up is a form of pull-up where you swing your body and use the momentum and a hip drive to get your body to the bar. It’s not cheating because it’s not meant to be the same exercise as a dead-hang pull-up. Some workouts call for a dead-hang pull-up – and in those you would not be allowed to kip.

Origins and Evolution of Human Diet was an academic web site at the University of Arkansas devoted to discussion of evolution and the human diet. They had good articles on the conferences link. Here is one from the archives: Boyd Eaton's Evolution, Diet and Health which argues that current w-6 : w-3 imbalance together with absolute dietary DHA intake quite low in human evolutionary perspective may be relevant to the frequency of unipolar depression.
In 1995, as Glassman was burning the last of his bridges at local gyms, he got a call from a friend who worked at the sheriff's department in Santa Cruz. The department had heard about him and wanted him to train officers. Glassman, who was in the middle of a breakup with a longtime girlfriend, decided to go. He set up shop in a health center called Spa Fitness and taught his own brand of fitness training, which he had begun calling CrossFit, to officers and anyone else looking to buy 60 minutes of sweat.
The biggest downside of this diet is how restrictive it is. A month is a pretty long stretch to make it without taking bite of quinoa, popping a chickpea, or sneaking a sip of wine (especially if you’re a busy, social person), and the protocol does not allow for even the smallest of slip-ups. From the manual: “One bite of pizza, one spoonful of ice cream, one lick of the spoon mixing the batter within the 30-day period and you’ve broken the “reset” button, requiring you to start over again on Day 1.” (Yikes!)

That severe carb restriction is meant to keep your body in a state of ketosis, says Alyssa Cohen, R.D. “Ketosis refers to the state of relying on ketone bodies for fuel,” Cohen explains. “Fat is the source used to make ketone bodies, so this diet aims to use fuel from fat, rather than carbohydrates [what our bodies primarily use for energy].” So basically, the keto diet helps you speed up the weight-loss process through fat burning.
On the surface, the Keto diet and the Paleo diet, two of the most popular diets out there, seem pretty similar. Both are low-carb plans that don't allow you to eat some of your favorite foods, such as cookies, pizza, and cereal. But there are actually some pretty important differences between the two diets that you should know, so you can figure out if either of them are right for you.
However, placing certain food groups on your "do not eat" list does have the potential work against you. "When a person sees the foods as 'off limits,' and consuming them is somehow breaking a rule and therefore sees themselves as a 'bad person,' mental damage is what is going to ensue long term versus the 30-day health benefits that you will receive," Smith cautions.
If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
The evolutionary discordance is incomplete, since it is based mainly on the genetic understanding of the human diet and a unique model of human ancestral diets, without taking into account the flexibility and variability of the human dietary behaviors over time. Studies of a variety of populations around the world show that humans can live healthily with a wide variety of diets and that humans have evolved to be flexible eaters. Lactose tolerance is an example of how some humans have adapted to the introduction of dairy into their diet. While the introduction of grains, dairy, and legumes during the Neolithic revolution may have had some adverse effects on modern humans, if humans had not been nutritionally adaptable, these technological developments would have been dropped.
But the truth is--and this is apparent to anyone watching Glassman wile away an afternoon at El Borracho--that CrossFit's success doesn't derive from any conventional business strategy. Glassman doesn't behave the way he's supposed to. Sometimes he rebels out of cunning, other times for the sheer petulant fun of it. Often, it's hard to tell which. As a result, CrossFit is a workout and a company no conventional trainer or M.B.A. would ever have built. Glassman is sitting atop a firecracker of a company. And the relevant question is, as always, What's he going to do now?
Glassman is proud of his role in all this, but the system puts him and CrossFit at a very real risk. As the world of CrossFit grows, as more businesses enter and profit, and his share of it becomes smaller, CrossFit's greatest success--gaining mainstream acceptance as exercise and a sport--could turn it generic, like baseball or skiing. "One of our greatest fears is becoming escalator," says Dale Saran, CrossFit's general counsel, referring to what was once a trademarked name brand of Otis Elevator. So, although Glassman keeps the CrossFit business model radically loose and open, he protects the brand name with an iron fist.
The Vegetarian Myth: Food, Justice, and Sustainability by Lierre Keith is against industrial farming. She spent 20 years as a vegan, and now reveals the risks of a vegan diet, and explains why animals belong on ecologically sound farms. And as all the neolithic foods we avoid are produced on industrial farms, she is against the foods we avoid. Here's a well thought out review by Eric Wargo: Clubbing Vegetarians Over the Head With the Truth.
There are about half a dozen diets that are very similar. They all recommend you eat "meat and veg" The reason Whole 30 works for me is because you can have potatoes and fruit. An example of a whole 30 meal would be: 2 pork chops, mashed potatoes made with chicken stock, green beans, finish with your choice of fruit. My favorite is a few grapes or pineapple chunks. Also the goal it to make it 30 days without cheating. There have been several times I would think: OK I can't cheat now I only have __ more days to go. Having an end in site helped me. When I started adding back in food groups after the 30 days. I figured out that I do not do well with Dairy. Now the only dairy I use is real butter. I never thought I could live without cheese... But now I don't think it's a good idea for me. So it helps you figure out what you can and can not eat and still feel good.
The final workout of the 2019 Open featured a descending ladder of thrusters and chest-to-bar pull-ups, totaling 105 reps of each movement, with a 20-minute time cap. Last year, 18.5 presented athletes with an ascending ladder of the same two movements, so it’s no surprise that nearly the same percentage of Open participants decided to tackle the final Open workout as prescribed in 2018 and 2019. Read on to see how the community fared with this year's rep scheme.
