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 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.
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.
So the best diet, as people much wiser than me have already stated, is probably the one you can stick to. If that looks like a low-carb diet, great. Maybe you can reap extra energy-burn rewards, assuming the results of the study hold up. The researchers themselves called for more studies, and replication will be particularly important given that their results seem to diverge from the rest of the evidence base.
Experts estimate that our ancestors consumed a one-to-one ratio of calories from meats to produce. Since you have to eat a lot of salad to consume the same amount of calories in a steak, the paleo diet should ideally include mostly fruits and vegetables, Katz says. However, many people don't realize that and eat too much meat. Consuming excess protein and not enough carbs can cause kidney damage and also increase your risk of osteoporosis, Dr. Ochner says. Plus, since most of today's meats are higher in saturated fat than those of yesteryear, it can increase the risk of heart disease, Dr. Katz says.
Eat low to moderate amounts of fruits and nuts. Try to eat mostly fruits low in sugar and high in antioxidants like berries as well as nuts high in omega-3, low in omega-6 and low in total polyunsaturated fat like macadamia nuts. Consider cutting off fruits and nuts altogether if you have an autoimmune disease, digestive problems or are trying to lose weight faster.
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.
Eat Like a Dinosaur: Recipe & Guidebook for Gluten-free Kids by Paleo Parents. The Book is a colorful children's story describing the paleo diet, chock-full of recipes without grains, dairy, soy or refined sugar. For those with food allergies, the top 8 allergens have been visually marked on each recipe for children to self-identify recipes that may contain eggs, nuts, fish, or shellfish. Published March 20, 2012.
The Stone Age Diet: Based on in-depth studies of human ecology and the diet of man by Walter L. Voegtlin. This was self-published back in 1975. Only a couple hundred copies were printed and distributed to friends and relatives. No one knew the book existed until some years later. In no way is he the father of the paleo diet. It is impossible to purchase. Apparently his descendents are planning a reprint, though the book is poorly written and not based upon factual anthropological information that even was available then. We have put up his Functional and Structural Comparison of Man's Digestive Tract with that of a Dog and Sheep. And a PDF can be found here.

The BMJ study “is a tour de force [of science],” added Sam Klein, a metabolism and obesity researcher at Washington University in St. Louis. But he shared Hall’s concerns, and felt the study came up with results that seem inconsistent with what we know about energy expenditure — likely because of the methodological issue Hall raised. “Using this pre-weight loss baseline as the point of comparison shrinks the effect size,” Klein summed up.
Two years ago I got formally diagnosed with chronic Lyme Disease. You can read more about that and what it means here. In my health journey, one of my goals has been to reduce inflammation in my system. There are a ton of factors that go into this, but one of the things I can control is the food I put into my body. Food, and restoring gut health, is a huge part of reversing chronic illness.
Between 2009 and 2018, competitors would qualify for the Games through participation an the Regionals. For the 2019 Games, CrossFit, Inc. decided to discontinue hosting the Regional qualifier and instead sanctioned previous independent fitness events as qualifiers separate from the Open. These sanctioned events were already widely participated in by CrossFit Games athletes, often used as a part of off-season training, around the world.
Paleoista: Gain Energy, Get Lean, and Feel Fabulous With the Diet You Were Born to Eat by Nell Stephenson. Paleoista is not only a how-to book, it is also a glimpse into the life of a woman who gives advice on how to eat this way, and lives the life, day in and day out.

“This feeding study, as the longest and largest to date, provides support for the carbohydrate-insulin model and makes a credible case that all calories are not metabolically alike,” said Harvard’s Ludwig, one of the study authors. “These findings raise the possibility that a focus on carbohydrate restriction may work better for long-term weight loss maintenance than calorie restriction.”

What makes some grub extra satisfying? "Fiber and protein can help," says Barbara Rolls, author of "The Ultimate Volumetrics Diet." Getting more bang for your bite matters, too: Low-energy-density foods, which yield big portions for few calories, "allow you to eat more without gaining weight," Rolls says. Want some of that? Make room for these secret-weapon picks.
The Dietitian's Guide to Eating Bugs by Daniel Calder is a comprehensive guide to the nutritional content of insects. He believes insect breeding and consumption are important elements sustainable living, particularly when it comes to complementing foraged plant material with meat products. Numerous insects contain nutrients similar to those found in more conventional livestock, except the feed to conversion ratio is much higher and they're much cheaper to breed. You can find the book at scribd. Also available in e-book format for $35.
Some Paleo dieters emphasize that they never believed in one true caveman lifestyle or diet and that—in the fashion of Sisson's Blueprint—they use our evolutionary past to form guidelines, not scripture. That strategy seems reasonably solid at first, but quickly disintegrates. Even though researchers know enough to make some generalizations about human diets in the Paleolithic with reasonable certainty, the details remain murky. Exactly what proportions of meat and vegetables did different hominid species eat in the Paleolithic? It's not clear. Just how far back were our ancestors eating grains and dairy? Perhaps far earlier than we initially thought. What we can say for certain is that in the Paleolithic, the human diet varied immensely by geography, season and opportunity. "We now know that humans have evolved not to subsist on a single, Paleolithic diet but to be flexible eaters, an insight that has important implications for the current debate over what people today should eat in order to be healthy," anthropologist William Leonard of Northwestern University wrote in Scientific American in 2002.
Some of the concerns are around micronutrients — supplementation of electrolytes, vitamins, and fiber is often required on low-carb diets, Zeratsky says. And sometimes, these diets can actually lower the blood sugar of a person with diabetes to the point where it’s too low, which is also dangerous. (Low-carb diets are not recommended for those people with type 1 diabetes or anyone on insulin due to that risk, experts note.)
A review published in December 2015 in the journal Diabetes Therapy suggested ultra-low-carb diets were effective at managing blood sugar, decreasing weight, and managing cardiovascular risk in individuals with type 2 diabetes in the short term, but the benefits were not sustainable over the long term. When compared with higher-carb diets over a period of longer than about 12 weeks, the health results were similar.
The new research is unlikely to end the decades-long debate over the best diet for weight loss. But it provides strong new evidence that all calories are not metabolically alike to the body. And it suggests that the popular advice on weight loss promoted by health authorities — count calories, reduce portion sizes and lower your fat intake — might be outdated.
Diet has been an important part of our evolution—as it is for every species—and we have inherited many adaptations from our Paleo predecessors. Understanding how we evolved could, in principle, help us make smarter dietary choices today. But the logic behind the Paleo diet fails in several ways: by making apotheosis of one particular slice of our evolutionary history; by insisting that we are biologically identical to stone age humans; and by denying the benefits of some of our more modern methods of eating.

Note: If you don’t have a grill, you can bake the chicken in the oven. Turn the oven to Broil (or 500°F), and place the raw chicken in a baking dish. Sear the chicken in the oven for 5 minutes. Reduce the oven temperature to 350°F. Brush the chicken with the curry sauce and finish cooking in the oven for 10 to 15 minutes (depending on thickness), until the internal temperature reaches 160°F.
Another 2014 study in the European Journal of Clinical Nutrition compared the effects of the Paleo plan to those of a standard low-fat diet on 70 obese, postmenopausal women. After six months, the Paleo group lost 14 pounds on average, while the other group lost nearly 6 pounds. After a year, the Paleo group had lost 19 pounds on average, and the low-fat dieters had dropped 10 pounds. A year later, both groups had regained some weight: The Paleo group was still down 10 pounds, while the low-fat group had dropped an average of more than 6 pounds.
