The CrossFit Games is an athletic competition sponsored by Crossfit Inc.[1] and Reebok.[2] The competition has been held every summer since 2007. Athletes at the Games compete in workouts that they learn about hours or days beforehand, consisting mostly of an assortment of standard aerobic, weightlifting, and gymnastics movements, as well as some additional surprise elements that are not part of the typical CrossFit regimen such as obstacle courses, ocean swimming, softball throwing, or ascending a pegboard.[3][4] The CrossFit Games stylizes their individual winners as the "Fittest on Earth".[5]
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)

In Defense of Food: An Eater's Manifesto by Michael Pollan gives a guided tour of 20th century food science, a history of "nutritionism" in America and a look at the marriage of government and the food industry. Then the book presents a commonsense shopping-and-eating guide, which like the paleo diet focuses on shopping the perimeter of the supermarket. He also now has a much shorter Food Rules: An Eater's Manual.
But critics argue that the unlimited amount of red meat the paleo diet allows may have an adverse effect on heart health in people with diabetes, as research links eating red meat in excess to poor heart health. (11)  If you have diabetes and don’t moderate your red-meat intake, this could be a big problem, as people with diabetes are 2 times as likely to die of heart disease as people who do not have diabetes. (12)
A 20-year prospective study of 82,802 women looked at the relationship between lower carbohydrate diets and heart disease; a subsequent study looked at lower carbohydrate diets and risk of diabetes. Women who ate low-carbohydrate diets that were high in vegetable sources of fat or protein had a 30 percent lower risk of heart disease (4) and about a 20 percent lower risk of type 2 diabetes, (34) compared to women who ate high-carbohydrate, low-fat diets. But women who ate low-carbohydrate diets that were high in animal fats or proteins did not see any such benefits. (4,34)
Keep up electrolytes. The major electrolytes in our bodies are sodium, potassium and magnesium. Because a low carb diet (especially a keto diet!) reduces the amount of water you store, this can flush out electrolytes and make you feel sick (called “keto flu”). This is temporary, but you can avoid or eliminate it by salting your food liberally, drinking broth (especially bone broth), and eating pickled vegetables. Some people also choose to take supplements for electrolytes, but it’s best to first consult a doctor that understands and supports keto/low carb lifestyles.
The Paleo Solution: The Original Human Diet by Robb Wolf, a research biochemist. Readers will understand digestion, how protein, carbohydrate and fat influence hormones, and how this plays into fat loss, health or disease. They'll understand the significance of dietary fats whether the concern is performance, health, longevity, or making your fanny look good in a bikini. The book goes into how lifestyle factors such as sleep and stress influence the hormone cortisol. It gets into basic blood work and what things people should ask their doctor to include to better assess inflammation and health. It also includes a detailed 30-day meal plan and a beginner exercise program. The exercise program is geared to the beginner or someone who is quite de-conditioned but the nutritional info would be helpful for anyone regardless of background. The author's website is Robb Wolf. He likes to pass out the information via weekly podcasts. Here's a video Introduction to the book. And here is an excerpt from the book: How to Keep Feces Out of Your Bloodstream (or Lose 10 Pounds in 14 Days). The many Amazon reviews all rave about the book. Published September 14, 2010.

Re: “Too old masters’ age group”… I have zero insight as to whether or not this will happen, but I’m a betting man & I’m putting my money on yes. If CrossFit lasts, which I think it will, I believe they’ll continue to evolve as the sport grows in size and age. It’ll come down to how many “too old” athletes end up being serious competitors. You’ll lead the way.
Made famous by the Atkins Diet and other similar weight-loss plans, low-carb diets are most well-known for shedding pounds fast. And despite what might initially come to mind when you think about low-carb diet plans — for example, eating loads of meat, cheese, oil and butter — research suggests that a balanced low-carb diet poses few health risks if done right.
Some people on a keto or low carb diet choose to count total carbs instead of net carbs. This makes it more difficult to fit in more leafy greens and low carb vegetables (which are filled with fiber), so you should only try that if you don’t get results with a net carb method. And, start with reducing sugar alcohols and low carb treats before deciding to do a “total carbs” method.
While the diet as a whole hasn't been well studied, the benefits of cutting packaged foods from your diet could be huge. According to the Harvard School of Public Health, three quarters of the average American's sodium intake (which is almost double what it should be!) comes from commercially prepared foods. And, one Public Health Nutrition study found that people who cook at least five times a week are 47% more likely to be alive 10 years later compared to those who rely more on processed foods.
Smoothies are generally discouraged on Whole30. However, if you must have one, choose a recipe with no added sweeteners and low-sugar fruits. This smoothie is more scoopable with a spoon, so you can slow down and savor it (important on Whole30!). The only sweet flavor comes from fresh raspberries — plus, this packs your bowl with fats from avocado and coconut milk.
Food and Western Disease: Health and nutrition from an evolutionary perspective by Staffan Lindeberg (MD at Lund University in Sweden) is the newest book promoting the paleo diet. It covers the link between diet and disease in the Western world (all major diseases, including cancer, heart disease, obesity, stroke and dementia) and towards a greater knowledge of what can be defined as the optimal human diet. Benefits and risks are detailed. The Amazon reviews are all 5 stars. Especially read Susan Schenck's detailed review. You can read a preview at Google Books
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.

You’ll be exposed to a ton of new, delicious recipes. If you know you’re not the cooking type, start simple. Instead of making the fancy egg-bake in a cast-iron pan, grab some eggs, veggies, sausage, and avocado then scramble your breakfast. Top it with (sugar-free) hot sauce, and you'll have yourself a solid meal in seven minutes. Don't be afraid to make that for breakfast five times a week; making similar meals over and over again is easier than trying to whip up (new) complicated ones.
Do not eat grains. This includes (but is not limited to) wheat, rye, barley, oats, corn, rice, millet, bulgur, sorghum, sprouted grains, and all gluten-free pseudo-cereals like quinoa, amaranth, and buckwheat. This also includes all the ways we add wheat, corn, and rice into our foods in the form of bran, germ, starch, and so on. Again, read your labels.
Fretting too much over calories. Slashing too many calories is impractical and unsustainable in the long-run. It can also do serious damage to your metabolism, Ward points out. Instead of obsessing over the number of calories, concentrate on the size of your meals. "Aim to have a quarter plate full of lean protein and carbs and a half plate filled with non-starchy vegetables," she suggests. In addition, add a small amount of healthy fats such as a slice of avocado or a tablespoon of olive oil for salad dressing, says the nutrition coach.
Primal Blueprint Quick and Easy Meals: Delicious, Primal-approved meals you can make in under 30 minutes by Mark Sisson and Jennifer Meier. Every recipe is accompanied by an ingredient list, a nutrient list, clearly written instructions, and a picture of the ingredients and a picture of the finished product. Note that this is a primal book and many recipes include dairy. Published March 25, 2011.
The American Academy of Family Physicians defines low-carbohydrate diets as diets that restrict carbohydrate intake to 20 to 60 grams per day, typically less than 20% of caloric intake.[2] A 2016 review of low-carbohydrate diets classified diets with 50g of carbohydrate per day (less than 10% of total calories) as "very low" and diets with 40% of calories from carbohydrates as "mild" low-carbohydrate diets.[18] In a 2015 review Richard D. Feinman and colleagues proposed that a very low carbohydrate diet had less that 10% caloric intake from carbohydrate, a low carbohydrate diet less than 26%, a medium carbohydrate diet less than 45%, and a high carbohydrate diet more than 45%.[16]
I LOVE Whole30. I preach it and I live it. The reason I am only posting 3 stars is because I am really disappointed in this cookbook, which I anticipated for months. I love crockpot meals and soups, and this didn't hardly have anything like that. Most of these meals did not look very appetizing. I don't want to have to purchase odd ingredients for that 1 meal and you'll be doing that with every one of these recipes. I hope they come out with another cookbook that focuses more on altering the more common meals that we are comfortable with.
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.
The Paleo Answer: 7 Days to Lose Weight, Feel Great, Stay Young by Loren Cordain. The author shows you how to supercharge the Paleo diet for optimal lifelong health and weight loss. Featuring a new prescriptive 7-day plan and surprising revelations from the author's original research, it's the most powerful Paleo guide yet. Published December 20, 2011.
Research from a 2008 study published in the Journal of the American Gastroenterological Association showed that patients with irritable bowel syndrome (IBS) report symptom improvements after initiating a very low-carbohydrate diet (VLCD). When participants with moderate to severe IBS were provided a two-week standard diet, then four weeks of a VLCD (20 grams of carbohydrates a day), the majority reported improvements in abdominal pain, stool habits and quality of life. (15)
When the 30 days are up, you can continue eating this way or gradually add some of the foods back in one by one to see which may have been causing your issues. Many people who become devotees of the lifestyle stick to a Paleo diet afterward (The Paleo diet is interpreted differently by different people, but in general, it’s a less strict, long-term lifestyle version of the Whole30).
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.
Our bodies normally run on glucose or sugar for energy, but we cannot make glucose ourselves and only store about 24 hours worth within our muscles and liver. Once glucose from carbohydrates is no longer available for energy due to following a low-carb diet, we begin to burn stored fat for fuel instead. This is why low-carb diets often lead to fast weight loss and other metabolic improvements within a relatively short period of time.

Catching Fire: How Cooking Made Us Human by Richard Wrangham. This book argues that the ease of digestion and the added nutritional value available in cooked food was the key behind the explosion of human intelligence. (Cooking gelatinizes starch, denatures protein, and softens all foods, permitting more complete digestion and energy extraction. As a result, the food processing apparatus shrinks, freeing energy to support a larger brain.) He then suggests that cooking led to what eventually became marriage and the sexual division of labor. The two most helpful reviews at Amazon get into great detail. The reviews average to 4+ stars.

Update: So I just finished my first whole30 round and I have to say that I'm super excited by the results. When I hopped on the scale today, I noticed that I had lost 26.6 pounds. I then measured myself and noted that I lost a total of 31.5 inches (-5" from chest, -2" from right arm, -3.5" from left arm, -8" from waist, -5" from hips, -4" from right thigh, and -4" from left thigh). I am really excited by my results!
Zhuang said that while the research shows an association, it cannot prove cause and effect. A randomized controlled trial would be needed to confirm the relationship between carbohydrate intake and AFib and assess the effect in a more ethnically diverse population. In addition, the study did not track participants with asymptomatic AFib or those who had AFib but were never admitted to a hospital, nor did it investigate different subtypes of AFib, so it is unknown whether patients were more likely to have occasional episodes of arrhythmia or persistent AFib. The study did not account for any changes in diet that participants may have experienced after completing the questionnaire.

While founders Dallas Hartwig and Melissa Hartwig are adamant in their book and on their website that “you’ve done harder things than this, and you have no excuse not to complete the program as written,” the Whole30 is not for the lazy or noncommittal. Without careful planning, a strong support system and dogged dedication, a business lunch, flight delay or date night can throw you off and send you back to the start. By nature, diets that eliminate entire food groups are tough to follow. On the other hand, it’s only 30 days.
We also talked about our meals, our struggles, and the results we were seeing from Whole30. Mentally, I felt more clear-headed and emotionally stable. I slept deeper and remembered more of my dreams, something that tends to never happen. (In one dream, I accidentally ate a slice of pizza and cried about it because if you break your Whole30 diet, you're supposed to start again from Day 1.)
In certain studies, improvement have been observed in Alzheimer’s disease and dementia patients fed a ketogenic diet, marked by factors including improved mitochondrial function. (7) A European Journal of Clinical Nutrition study pointed to emerging data that suggested the therapeutic use of ketogenic diets for multiple neurological disorders beyond epilepsy and Alzheimer’s, including headaches, neurotrauma, Parkinson’s disease, sleep disorders, brain cancer, autism and multiple sclerosis.

Welcome Denise and that is great news that you have discovered low carb to help with your T2 diabetes. Read this post which may really explain how diabetics especially can be helped by lowering their carbs, how it may lower your insulin resistance and improve your control. Where you set your carb limits will depend on how high your current carb intake is and current medication. You may need to be seen by a diabetes educator, dietician or health professional as your need for medication may need to be reduced in conjunction with lowering your carbs. Ensure they are low carb friendly practitioners.
Making uninformed choices. "When you lower your carbs intake, you’ll naturally need to increase the percentage of protein and fat in your diet," Ward explains. Many people turn to processed, unhealthy options like keto cakes, sugar-laden protein bars and salami to get these nutrients. Needless to say, it does more harm than good to their health. Get your required dose of protein and fat from healthy and natural sources like eggs, yogurt, milk, fish, tofu and nuts.

Obesity, heart disease, and diabetes: These are just a few of the health conditions that proponents of thePaleolithic diet, or caveman diet, blame on our sedentary lifestyles and modern diets, which are loaded with sugar, fat, and processed foods. Their proposed solution? Cut modern foods from our diet and return to the way our early hunter-gatherer ancestors ate.
Since then, I've reintroduced legumes, soy, added sugar, and dairy back into my diet. Since I'm lactose intolerant, I was most afraid of dairy, but it seems as of my dairy intolerance has disappeared, which is an unexpected positive. I definitely sleep worse, though, and feel more bloated when I enjoy dairy or carbs with gluten. So going forward, I'll be eating these with more moderation than before.
In 1972, Robert Atkins published Dr. Atkins Diet Revolution, which advocated the low-carbohydrate diet he had successfully used in treating patients in the 1960s (having developed the diet from a 1963 article published in JAMA).[56] The book met with some success, but, was widely criticized by the mainstream medical community as being dangerous and misleading, thereby limiting its appeal at the time.[57]
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?

A ketogenic diet — one form of a very low-carb diet — is a high-fat diet that strictly eliminates almost all sources of glucose in order to put the body into “fat-burning mode,” also called nutritional ketosis. The ketogenic diet goes by several different names, including the “no-carb diet” or “very low carbohydrate ketogenic diet”(LCKD or VLCKD for short).
I consider myself to be a pretty healthy eater. I’m gluten-free for health reasons, and I always try to make sure to eat a ton of vegetables. I make things from scratch, and am wary of overly processed foods. However, just like most of us, I can eat too much chocolate or indulge in something really carb-heavy and feel the after effects. For me, this means joint pain and the feeling of being hungover, along with many other equally fun symptoms.
You’ll lose weight because any time you restrict entire food groups, your calorie intake tends to be lower, Sandon says. And whenever you burn more calories than you consume, you'll have weight loss, she says. (2) The focus on lean protein, fruits, and vegetables over calorie- and sodium-rich processed foods can also contribute to weight loss, though she also points out that the paleo diet wasn’t created to be a weight loss diet. (3)

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.

Net carbs is simply total carbs minus fiber and non-digestible sugar alcohols, like erythritol. (This doesn’t apply to high glycemic sugar alcohols, like maltitol.) We don’t have to count fiber and certain sugar alcohols in net carbs, because they either don’t get broken down by our bodies, are not absorbed, or are absorbed but not metabolized. (Read more about sugar alcohols here.)

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].


I started seeing a nutritionist, who has started me on a B-12 injection 2 times monthly, and a LCHF diet. He wants me to stay between 20-35 carbs daily for at least 3 months. He says I need to buy ketone strips, to make sure I don’t go into ketoacidosis, however, I am otherwise healthy, and not diabetic. Is this something I need to be overly concerned about? I’m on my 4th day of approx. 25 carbs daily, and other than a slight headache, I feel fine.
Certain food groups (like sugar, grains, dairy and legumes) could be having a negative impact on your health and fitness without you even realizing it. Are your energy levels inconsistent or non-existent? Do you have aches and pains that can’t be explained by over-use or injury? Are you having a hard time losing weight no matter how hard you try? Do you have some sort of condition, like skin issues, digestive ailments, seasonal allergies, or chronic pain, that medication hasn’t helped? These symptoms are often directly related to the foods you eat—even the “healthy” stuff. So how do you know if (and how) these foods are affecting you?

Two friends and I discussed the article, and then one proposed something unbelievable: "We should do Whole30 together." After considering what Philipps' had to say about it, I decided to give it a try. Then Health editor in chief Lori Leibovich asked me to document my Whole30 experience with daily video diaries on Health Instagram stories, and I knew there was no turning back. I was about to do my first diet ever.

What a fabulous start you are making. There is no denying the change will take some time. I know as I have a fussy 7 yr old who even used to hate roast chicken, and last night he went back for thirds!!! or cauliflower rice (makes me a happy mumma). If your daughter loves fruit that is great, but try and get her onto the less sugary fruits and nutrient dense ones like berries and add some cream to keep her full. Take a look at my Kids pages for more ideas and tricks. I always let my youngest choose 1 thing on the plate he doesn’t have to eat but he has to eat the rest, he thinks he has some control so is happy. Just keep trying and do the best you can and be proud of what you are able to change then look back to see how far you have come.
I often get caught up in focusing on numbers and scales, so I decided not to officially weigh myself before or after Whole30. But I can attest that everything about my body just felt better. I know saying something like "I lost eleven pounds" would sound much more convincing, but I could see that my stomach was slimmer, as was my face (which is awkwardly the first place I gain weight).
More evidence of the heart benefits from a lower-carbohydrate approach comes from a randomized trial known as the Optimal Macronutrient Intake Trial for Heart Health (OmniHeart). (35) A healthy diet that replaced some carbohydrate with protein or fat did a better job of lowering blood pressure and “bad” LDL cholesterol than a healthy, higher-carbohydrate diet.

Still, many scientists have expressed concern that we do not yet have enough evidence to make any strong claims about the paleo diet’s health benefits, especially its long-term effects. In fact, in an article in response to the first review, authors Tanis R. Fenton and Carol J. Fenton, from the Cumming School of Medicine in Canada, wrote a letter to the editor in which they expressed their disappointment with the review.

The China Study is frequently cited when criticizing the Paleo Diet – focusing on a vegetarian diet and consuming rice is healthier than the Paleo Diet. I respectfully disagree with the conclusions drawn from that book but that’s awesome if you want to go plant-based! [7], and will leave you to make your own conclusions based on your own self-experimentation.
