A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
Fruits are not only delicious, but they’re also great for you. That said, fruits (even paleo-approved ones) contain large amounts of fructose which, while much better than HFCS (high-fructose corn syrup), is still sugar. If you’re looking to lose weight on the paleo diet, you’ll want to cut back on your fruit intake and focus more on the vegetables allowed on the paleo diet. However, feel free to have one to three servings of fruit a day. Check out this list of paleo diet fruits and see if you’re not hungry by the end! (We’ll admit, we’re partial to blackberries!)
All involve eating whole foods (as opposed to packaged and processed) and filling your plate with quality sources of protein, healthy fats, complex carbohydrates, and vitamin-, mineral-, and fiber-rich vegetables. (Again, we’re talking about the ones that fall somewhere on the healthy spectrum, not unhealthy fad diets like, ahem, the Grapefruit Diet.)
Your only job during the Whole30 is to focus on making good food choices. You don’t need to weigh or measure, you don’t need to count calories, you don’t need to purchase everything organic, grass-fed, pastured, or local. Just figure out how to stick to the Whole30 rules in any setting, around every special circumstance, under any amount of stress… for 30 straight days. Your only job? Eat. Good. Food.
First of all, it’s unclear if it can really live up to its claim to improve overall health by following the diet of our ancestors. While we can all benefit from reducing our intake of processed foods and increasing fruit and vegetable consumption, many dispute whether our ancestors were really all that much healthier than we are today given their significantly shorter life span. In fact, one study even demonstrated that they may have had increased rates of atherosclerosis, or hardened arteries. (5)
Thank you CFA coaches for always scaling the WOD for my medical needs, but still making the WOD fun and challenging. I may not be able to lift heavy or ever be a part of the CF games, but I do feel like a part of CFA family and with that I could never go back to a gym. It’s been a privilege meeting and working out with great people. I feel honored to be selected CFA Athlete of the Month. CROSSFIT PROUD!!!
And if you've really fallen off the bandwagon, a 30-day reset might be what you need. "Sometimes we need to do a complete overhaul of something in order to change that habit," Daniella Cohn, RD, explains. "Following a temporary diet that eliminates all of the junk that we tend to eat daily can be a great way to remind ourselves to pay attention to what we are eating and make healthy and informed food choices."
The Paleo Diet: Eating like your ancestors doesn't guarantee you'll lose weight. While the diet emphasizes plenty of foods that are good for weight loss, such as lean protein and fruits and vegetables, you would still need to eat fewer calories to drop a few pounds. So if you're binging on nuts and fruit, you could actually gain weight on the Paleo Diet.
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.
CrossFit has been a full-on addiction for me. My lifestyle is so much better because of it. I eat better, feel better and look better. Every day I look forward to that hour or two after work where I can just hang out with my friends and let off some steam in a workout. The best part of this is that I get to have friendly competition with others, and most importantly myself.

Some CrossFitters drink WAYYY too much “kool-aid.” You’ll run into CrossFit people who think CrossFit is the be-all, end-all training solution, and anybody that doesn’t do CrossFit is a wuss. If you can do 20 pull ups, they can do 22, and do them faster than you, after doing 25 handstand push ups and running 400 meters. I tend to dislike elitists no matter what they are elitist about, and CrossFit is no exception.
In his gruff way, Glassman recounted his story for the faithful: how a novel, exquisitely punishing system of exercise he had designed, centered on the WOD (workout of the day; it's pronounced "wad"), had started in his backwater Santa Cruz gym, then turned into an online phenomenon, then paved the way for 6,775 CrossFit locations (soon to be 10,000), and now was fast becoming its own sport. (This month, the finals of the CrossFit Games will be broadcast live on ESPN2.) He explained the contrarian way he thinks about the CrossFit business (he shuns most new sources of revenue) and how he goes about protecting its brand (viciously).
I cannot possibly put enough emphasis on this simple fact—the next 30 days will change your life. It will change the way you think about food. It will change your tastes. It will change your habits and your cravings. It will restore a healthy emotional relationship with food, and with your body. It has the potential to change the way you eat for the rest of your life. I know this because I did it, and millions of people have done it since, and it changed my life (and their lives) in a dramatic and permanent fashion.
Glassman attracted a little flock. "I was looking for a trainer, and a friend of my wife's went to Spa Fitness," says Ben Elizer, who today is CrossFit's chief information officer. He went to Spa Fitness and was told he had his pick of two: "one guy who is really nice and not that good, and another guy who is really good but super-opinionated and arrogant"--Glassman, of course. Glassman's crew was tight-knit. He even ended up marrying one of his clients, a hairdresser named Lauren Jenai. When the Spa Fitness owner inevitably showed the CrossFitters the door, and they leased a corner of a jujitsu studio, Lauren would manage the books and teach CrossFit classes herself. Soon they outgrew that space, and the Glassmans took their motley little group of cops, jujitsu fighters, and tech-company commuters to a 1,250-square-foot truck garage on a remote road three miles out in Soquel. In 2000, a number of clients asked if Glassman could put the WODs online so they could do them when they traveled, so he put up CrossFit.com.
In fact, the health benefits of the paleo diet are unproven. "Our ancestors ate this way and didn't have many of the chronic diseases we do, but that doesn't mean the food they ate is the reason why; drawing that conclusion would be like saying we live three times longer than our Paleolithic ancestors because we eat fast food," says Christopher Ochner, MD, research associate at the New York Obesity Nutrition Research Center at St. Luke's and Roosevelt Hospitals. Still, a handful of small studies have tried to determine if a paleo diet is a healthier diet. One small study published in the journal Diabetologia found that the diet improved blood sugar over 12 weeks compared to a Mediterranean one that allowed grains, low-fat dairy, and oils, but it's hard to say whether researchers would come to the same results in a larger study.
While gorging on cheese and bread post–Whole30 sounds fun, it's not the way you're supposed to end the elimination diet. Instead, you want to slowly reintroduce certain food groups to see how each individually affects your body and mind. I decided to go this route because I was interested in discovering food sensitivities. And frankly, I was afraid of puking the second I came into contact with dairy or alcohol.

As CrossFit gets bigger and bigger, Glassman is no longer the underdog. Well-known employees and boxes have been tossed out after clashing with Glassman or voicing disagreements with the CrossFit approach to fitness or nutrition--or, in particular, criticizing other CrossFitters close to Glassman. In 2009, Robb Wolf, one of the first affiliates, was exiled. "You have to kowtow and not let your star shine too brightly," Wolf says. "He's always had this tendency toward incredible kindness, but he also has this rattlesnake intensity and cruelty."
This biggest success of Week 2 was attending a happy hour networking event completely sober. I headed there with a friend who was also doing Whole30, and we vowed to be each other's support system. We ordered seltzer waters together and proudly said no to the cheeseburger sliders and cheese board. Leaving the event, I felt empowered knowing I had it in me to refuse alcohol and fatty food, something I'd never tried before. Plus, I now knew I didn't have to use alcohol as a social crutch.
The WHO trial (so named because the international team of principal investigators contained World Health Organization members) tested the potential of clofibrate, a “pre-statin” cholesterol-lowering agent, to reduce heart attack morbidity and mortality. The investigators ultimately concluded that clofibrate "cannot be recommended as a lipid-lowering drug for community-wide primary prevention of ischaemic heart disease.” Nevertheless, clofibrate remained in use until 2002, when it was pulled for increasing cancer rates. In their review of studies such as the WHO trial, Uffe Ravnskov and David Diamond observe, “Despite the largely disappointing findings from 50 years of cholesterol lower[ing] trials, the indictment and conviction of cholesterol as the causal agent in CVD [cardiovascular disease] has stood the test of time. … [Yet] the grand effort to reduce cholesterol as a strategy to improve health has failed.”
