The Paleolithic or “Paleo” diet seeks to address 21st century ills by revisiting the way humans ate during the Paleolithic era more than 2 million years ago. Paleo proponents state that because our genetics and anatomy have changed very little since the Stone Age, we should eat foods available during that time to promote good health. Our predecessors used simple stone tools that were not advanced enough to grow and cultivate plants, so they hunted, fished, and gathered wild plants for food. If they lived long enough, they were believed to experience less modern-day diseases like diabetes, cancer, and heart disease because of a consistent diet of lean meats and plant foods along with a high level of physical activity from intensive hunting. However, the life expectancy of our predecessors was only a fraction of that of people today.
CrossFit Inc. reserves the right to send 4 athletes who have failed to qualify otherwise to the Games. This is a complete CYA move. If a fan favorite fails to qualify through the Open or through a sanctioned event, you can believe Dave Castro will send a quick text message saying, “I got you covered, boo. You've always had the capacity in my eyes <3”.
Both feeling hungry all the time and never feeling hungry are common on the Whole30 diet, especially during the first two weeks as your body adjusts to new sources of energy. Eventually, though, you shouldn’t feel those pangs since protein and fiber are filling, and you’ll get plenty of both. Plus, you’re allowed to eat as much as you want and add Whole30-compliant snacks to your meal plan, provided you truly are hungry. One small study of 29 participants published in Nutrition and Metabolism in 2010 found Paleo eaters (who have relatively similar diets to Whole30 followers) felt just as full but consumed fewer calories than their Mediterranean counterparts.
In my first CrossFit experience three years ago, I almost made myself puke because I wanted so badly to finish with a good time. Last year, I did another CrossFit workout that I hadn’t properly prepared for and cranked out 100 pull ups quickly…and I ended up walking around with T-rex arms for a WEEK because I physically could not straighten them. Not kidding.
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
You may notice that the following meal plans do not include any snacks. This is because, technically, snacking isn’t really something you should do while on a Whole30. Just be sure you’re getting enough food at each meal (which may be hard at first as you adjust to eating whole, real food and no processed “foods”) and you won’t need to snack. If you do feel the need to eat something between meals, try to keep some cut-up veggies on hand so you’ve got something easy and quick nearby and aren’t tempted to grab something non-Whole30.
With a very simple shift we not only remove the foods that are at odds with our health (grains, legumes, and dairy) but we also increase our intake of vitamins, minerals, and antioxidants. Here is a great paper from Professor Loren Cordain exploring how to build a modern Paleo diet: The nutritional characteristics of a contemporary diet based upon Paleolithic food groups. This paper also offers significant insight as to the amounts and ratios of protein, carbohydrate and fat in the ancestral diet.
A 2015 study in the Journal of the American College of Cardiology found that 76 people who followed the Paleo diet for 60 days (as well as those who followed vegan, Mediterranean and DASH plans for the same length of time) lost an average of 9 pounds and showed improvement in their blood pressure levels. The effects were greatest and most sustained among people who also attended regular diet support group meetings.
Cordain admits that meat leads to plaque and increases cholesterol where plants wouldn’t. And science establishes that plaque and cholesterol lead to heart attacks and strokes. But Cordain argues that plaque alone is insufficient to cause harm. Rather, it is plaque combined with inflammation that causes heart attacks and strokes. So avoid acid, salt, legumes, wheat, starchy vegetables, dairy, oil, fatty meats, and grains because they cause inflammation. But if both science and Cordain agree that plaque is a necessary part of the heart-disease equation—and that meat causes plaque—why should we follow Paleo rather than just forgo meat?
I was so happy to find your whole30 menu, this is the first time on this plan and mid week 2 I was at a loss of what to eat. I am great at counting carbs but this is all new and couldn’t use my old standby meals. MY reason for doing this is I want to get the fake sugars out of my daily life and this was a great way to jump start this for me. meal planning is a lot of work and thank you
Paleo eating requires a lot of planning, prep time, and mental resolve. For instance, eating out on the diet isn't as simple as ordering chicken and a salad. Think: In what oil was the chicken cooked? Did any of the salad toppings come processed, canned, or packaged? "As with every elimination diet, it's just not doable long term," Dr. Ochner says. While weight loss is far from the sole purpose of eating paleo, going on and off of the diet can lead to big weight swings. Any yo-yo diet starts in weight loss from both muscle and fat, and usually ends with weight gain of all fat, which contributes to a slower metabolism and increased insulin resistance.
This list is going to be a little longer than the last. You cut out all sugar (both real and all substitutes whether natural or artificial, like honey, maple syrup, Splenda, etc.). No grains, legumes (including all forms of soy), dairy, or alcohol. You’re also told to avoid additives like MSG and carrageenan, although that should happen naturally if you’re sticking to whole foods.
It’s also worth noting that athletes who receive a CrossFit Games invitation from a Sanctional event win do not necessarily need to compete in the Open to make it to the Games. Additionally, athletes that place high enough in the Open to receive a bid to the Games, and athletes who are deemed National Champion for their country, will receive no additional benefit (in respects to the Games seeding directly) with a win at a Sanctional event.
CrossFit, Inc. has also been criticized for having a "cavalier" attitude towards rhabdomyolysis by promoting a character known as "Uncle Rhabdo" (a cartoon clown dying in a dramatic fashion—hooked up to a dialysis machine, with his kidneys and intestines falling on the floor). In response to this criticism, Greg Glassman stated "We introduced (Uncle) Rhabdo because we're honest and believe that full disclosure of risk is the only ethical thing to do."
Due to CrossFit's official partnership with Reebok, competitors at the 2015 Games were banned from wearing Nike footwear. Nike arranged for several trucks to be parked near the main entrance to the arena, which served as mobile billboards with the slogan "Don't ban our shoe, beat our shoe". The partnership also prohibits Nike from labeling its Metcon shoes as intended for CrossFit – the brand uses the term "high intensity training" instead.
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.
You’ll stay pretty full on the Paleo diet. Nutrition experts emphasize the importance of satiety, the satisfied feeling that you’ve had enough. You shouldn’t feel hungry on this diet – protein and fiber are filling, and you’ll get plenty of both. One small study of 29 participants published in Nutrition & Metabolism in 2010 found Paleo dieters felt just as full but consumed fewer calories than their Mediterranean counterparts.
Fattening cattle with corn changes the lipid balance and is clearly not the natural diet for a grass eating cow. In Simple change in cattle diets could cut E. coli infection researchers have found that when cattle were fed hay or grass for just five days before slaughter, much less E. Coli cells were present in the animal's feces and virtually all surviving E. coli bacteria were not acid-resistant and were killed by human stomach acid.

Eat WELL Feel GOOD: Practical Paleo Living by Diane Frampton has over 200 recipes that makes paleo eating simple, delicious, and ultimately, intuitive. So they claim. There are only a few reviews at Amazon. They all like the book, but their lack of details makes it appear that they are not truly independent reviews. The recipes have a Crossfit appeal to them. Chef Rachel Albert has made some of the recipes and posted here [archive.org].
On that spring day across America, the CrossFit faithful gathered--and toiled. There were hundreds of thousands of them, certainly. Maybe a million, maybe two. In an old industrial facility in New Orleans, they hoisted themselves on gymnastic rings and did dips up there. In a strip mall in Santa Cruz, California, they threw 20-pound medicine balls against a wall over and over again. In a business park near the Dulles airport in Virginia, they pushed weighted barbells above their heads, first once a minute, and then as fast as they could for three minutes straight--or until they couldn't lift their arms.
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.” 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.
