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.
Chris Masterjohn has Cholesterol: Your Life Depends on It!, another web site pointing out that the war on cholesterol and the push to put people on statins is misguided. The site argues it is actually polyunsaturated fats, not saturated fats or cholesterol, that contribute to heart disease, cancer, liver damage, and aging. He also has a popular blog.

You likely will lose weight on Whole30—“many people do appear to lose weight while following the plan, likely due to the decreased reliance on processed foods and increased consumption of whole foods, such as fruits and vegetables,” says Cohen. But it wasn’t designed for weight loss, and once the 30 days are over, you may gain all the weight back as you reintroduce your body to a normal diet.

For immediate weight loss, Paleo is a great and healthy solution. But after carefully reading and considering, I’m unconvinced that Paleo is optimal for long-term health. I think, in fact, it might lead to heart disease and other ills associated with heavy meat consumption. Although many of Cordain’s theories fall apart long-term, I thoroughly enjoyed the read and highly recommend the book. You should read critically and decide for yourself.


Prior to starting, athletes should state their name, and show and state the weights and equipment to be used. All video submissions must be uncut and unedited in order to accurately display the performance. A clock or timer, with the running workout time clearly visible should be in the frame throughout the entire workout. Shoot the video from an angle so ALL exercises can be clearly seen meeting the movement standards. Videos shot with a fisheye lens or similar lens may be rejected due to the visual distortion these lenses cause. If an athlete needs someone to adjust their camera during the WOD to capture all movements, this is acceptable, as long as the flow of the workout and the athlete is in view the whole time. It is the athletes responsibility to ensure their video meets the standard.
Generally speaking, dieters are advised to eat between 20-30 grams of carbohydrates per day in order to maintain ketosis. To put this into perspective, a quarter cup of steel cut oats has 29 grams of carbs and a banana has roughly 27 grams of carbs. So if you have a few bites of oatmeal or a small piece of fruit, whoops! That's your carb intake for the day.
But listen--we'd both been relatively inactive for years and each about 25 pounds overweight. Between the two of us we lost 34 lbs in 30 days and we are still going to keep up a serious commitment to Whole 30, with a few supplemental treats now and then. We feel better, we have new confidence about getting dressed in the morning, and we're more fit than in years, mostly because we have the energy to do more. The amazing thing is that you will NOT feel hungry if you hang in there and consistently prepare foods as per the cookbook/menus. There is also a very supportive and helpful forum online to supplement the book.
The paleo diet runs on the same foods our hunter-gather ancestors supposedly ate: fruits, vegetables, meats, seafood, and nuts. "By following these nutritional guidelines, we put our diet more in line with the evolutionary pressures that shaped our current genetics, which in turn positively influences health and well being," says Loren Cordain, PhD, professor of health and exercise science at Colorado State University and author of The Paleo Diet. He says the diet lessens the body's glycemic load, has a healthy ratio of saturated-to-unsaturated fatty acids, increases vitamin and nutrient consumption, and contains an optimal balance of protein, fat, and carbohydrates.
In response to these criticisms, CrossFit, Inc. claims, “CrossFit is relatively safe even when performed with poor technique, but it is safer and more effective when performed with good technique.”[58] CrossFit, Inc. also claims risk for injury can be reduced by properly scaling and modifying workouts, a concept taught on its website and at the CrossFit Level 1 Trainer Course.[59][60]
“Hartwig, a sports nutritionist and cocreator of the Whole30 diet plan, packs her fourth book on the subject with 150 recipes that are, as the cover proclaims in all-caps, “totally compliant.” That means heavy emphasis on eggs, meat, fish, and fresh vegetables, but no grains, dairy, legumes or added sugars. Whether or not one buys into Whole30, there is no denying that Hartwig has come up with a clever array of healthy and flavorful dishes. Highlights include Asian beef zoodle (zucchini noodles) soup, which is similar to Vietnamese pho but uses zucchini noodles, and grilled Jamaican jerk salmon with fresh mango salsa. Many of the recipes come courtesy of guest cooks from various food blogs. For instance, Michelle Smith, from the Whole Smiths blog, contributes cherry-chipotle BBQ chicken thighs, with the fruit providing the sweetness and ground chipotle bringing the heat. Veteran food and cocktail photographer Brent Herrig drives home the point that a burger served on a tomato slice is as delectable as one on a bun, and that meatballs do just fine in a cream sauce made with coconut milk.

Paleo critics point out that not all grains are created equal—whole grains do not spike your blood sugar as much as refined grains. Even so, paleo dieters still steer clear of grains because they contain different compounds and proteins like gluten, lectins and phytates, which they claim cause inflammation in the body and block other nutrients from being absorbed. Paleo critics say these compounds are not a problem unless you have an allergy or sensitivity.
Saturated fat has been demonized by our health authorities and media. What is the basis for this position on Saturated fat? Are current recommendations for VERY low saturated fat intake justified? How much saturated fat (and what types), if any should one eat? Without a historical and scientific perspective these questions can be nearly impossible to answer.
These are great! Thanks. I was wondering what your budget is for all this food. I seem to spend much more money for groceries when we are on whole 30. I try to shop at Costco and discount stores as I can, but it still seems like a lot. My shopping list I created for week one on my previous w30 was like $350 for a family of 5 (including food for one vegan). Is this normal?
Glassman has always been a fighter, an us-versus-them kind of guy, and as his company has grown, so has his arsenal: CrossFit now has seven lawyers on staff and at any given time is engaging 12 to 20 outside legal firms to pursue trademark-infringement cases. CrossFit has a database of more than 5,000 possible infringements and is litigating a dozen lawsuits in the U.S. and several more internationally.
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.
