It changed our lives, and we want it to change yours too.

Obviously, reductions in the desire to be physical active, experiencing brain fog and being cranky are pretty counterproductive for people looking to feel healthier and lose weight, so these effects are something to monitor yourself for. If you’re feeling very sluggish, moody, or like you have “brain fog” and can’t think clearly while after drastically reducing your carbs over the course of several weeks — especially if you changed your diet rapidly and reduced carbs to very low ketogenic levels — try reintroducing some carbs several days a week until you feel better. Experiencing the benefits of low-carb diets can take some trial and error, plus some patience.
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.
The toe to bar requires an athlete start each set at a dead hang from a pull-up bar, with shoulders, arms, hips and legs at full extension. Each repetition consists of an athlete bringing both feet behind the perpendicular vertical plain created by the pull-up bar, and finishes with both feet simultaneously in contact with the pull-up bar, between the athlete’s hands.
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]

Ever start a diet and get immediately discouraged when the number on your scale hasn't budged after a week or two? Whole30 forbids weighing yourself — a practice which can help shift your mindset to how you're feeling as your success metric. "The scale shouldn’t drive your mood, food choices or overall mindset," says Amy Shapiro, RD. "Continue to live a healthy life and measure how you feel energy and clarity wise." Which means being honest with yourself about how your body feels after going to town on that cheese plate. One of the biggest realizations for me was how much clearer and more energetic I feel when my weekend diet doesn't consist of vodka-sodas and takeout food.
The Great Cholesterol Con by Anthony Colpo. The definitive book on the non-dangers of dietary cholesterol and saturated fat was The Cholesterol Myths by Uffe Ravnskov, 2000. This book is six years newer. Its forward is by Uffe Ravnskov. To get a wonderful description of the book read the leading review at Amazon. The many reviews there average to 5 stars.
Research shows that a diet high in refined carbohydrates and sugar contributes to free radical damage and actually feeds cancer cells, possibly helping them proliferate faster. Because low-carb diets dramatically cut down sugar and lower intake of grains and processed foods, they might act like a natural cancer treatment, causing immunity to improve as oxidative stress goes down.

After that initial hump, things got a lot better. I had energy to do some things that I usually had no energy to do. I was doing yoga, and was able to go on walks. This was a big deal for me. Going through treatment for Lyme Disease is exhausting. Often I feel like I don’t have enough air to hold up my body — it’s a feeling of intense can’t-get-out-of-bed-exhaustion. So to have a little more pep in my step felt invaluable.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars. [2] The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.

The Primal Blueprint: Reprogram your genes for effortless weight loss, vibrant health, and boundless energy by Mark Sisson is a journey through human evolution, comparing the life and robust health of our hunter-gatherer ancestors with a day in the life of a modern family. The author offers a solution in 10 empowering Blueprint Lifestyle Laws: eat lots of plants and animals, avoid poisonous things, move frequently at a slow pace, lift heavy things, sprint once in a while, get adequate sleep, play, get adequate sunlight, avoid stupid mistakes, and use your brain. The reader learns how the right high-fat diet can actually help one lose weight and how popular low-fat, grain-based diets might trigger illness, disease, and lifelong weight gain. The author presents a comprehensive, well thought out paleo style eating plan in a humorous and organized manner. He backs up all his work with research, natural wisdom, and historical timelines. He disputes the role of dietary saturated fat in causation of arteriosclerosis, the role of cholesterol in promotion of heart disease, and the costly over-promotion of expensive, potentially toxic statin drugs. He criticizes our massive overeating of refined carbohydrates and urges avoidance of grains, cereals, bread and sugar. There is specific recommendation for "primal" food including more natural healthy fats and meats, fruits, veggies, and nuts. Some reviewers consider this to be the best of the various paleo books. The many Amazon reviews average to 5 stars. The author's popular and worthwhile web site: Mark's Daily Apple. The 2nd Edition was published January 14, 2012.

According to the CDC, cardiovascular disease is the number one cause of death in the United States. Interestingly however, our Paleolithic ancestors and contemporarily studied hunter-gatherers showed virtually no heart attack or stroke while eating ancestral diets. The references below will explore these facts to better help you understand the heart-healthy benefits of a Paleo diet.
Research into the effectiveness of low-carbohydrate, high fat (LCHF) diets for preventing weight gain and diabetes has produced conflicting results, with some suggestion that diet suitability is not generalizable, but specific to individuals.[11] Overall, for prevention, there is no good evidence that LCHF diets offer a superior diet choice to a more conventional healthy diet, as recommended by many health authorities, in which carbohydrate typically accounts for more than 40% of calories consumed.[11]
Since 1860, and more recently in 1972 with the Atkin’s diet, low carbohydrate (low-carb) diets have been a strategy for weight loss.  Today, there continues to be an interest in low-carb approaches such as Atkins, Banting, ketogenic, and South Beach.  While all low carbohydrate approaches reduce the overall intake of carbohydrates, there is no clear consensus on what defines a low-carb diet.  There are three macronutrients—carbohydrates (4kcal/gm), fat (9kcal/gm) and protein (4kcal/gm) found in food.  Therefore, studies have defined low carbohydrate as a percent of daily macronutrient intake or total daily carbohydrate load.  We will define it here as:
Like the Paleo Diet, the Keto Diet is low in carbs. But the primary goal of the Keto Diet is to put your body into a state of ketosis, which is when your body uses fat instead of carbohydrates as its primary energy source. When your body enters ketosis, fat travels to the liver and makes an acid called ketones, which enter your bloodstream and are converted into energy.
That said, you don’t have to jump in with both feet. Schmidt recommends trying to eat under 200 g of carbs a day initially (a moderate-carb diet) and then adjust lower based on how you feel. “If you start paying attention to the carbs in your diet, you’ll eat fewer processed foods,” she says. And it’s those whole foods that are the basis of good health.
Still, it was a tad depressing to watch my boyfriend eat whatever he wanted while I was on the sideline sipping tea. "I miss sharing food memories with you," he said at one point. Sigh. So the next day, we headed to a local brunch spot, and I ordered a Whole30–compliant dish from the menu. I got a bunless burger topped with a fried egg, avocado, lettuce, tomato, and onion plus a side salad instead of fries. Let me tell you, this bunless burger tasted like the juiciest thing I'd eaten in my entire life. After nearly two weeks of cooking every meal, it was nice to have someone else do it for me.

Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.
Your body uses carbohydrates as its main fuel source. Complex carbohydrates (starches) are broken down into simple sugars during digestion. They're then absorbed into your bloodstream, where they're known as blood sugar (glucose). In general, natural complex carbohydrates are digested more slowly and they have less effect on blood sugar. Natural complex carbohydrates provide bulk and serve other body functions beyond fuel.
Before medications, carbohydrate control has been the cornerstone of glycemic control in both type 1 and type 2 diabetes.  Dietary carbohydrates increase insulin needs, and reduction of carbohydrate intake can improve glycemic control.[22]  A recent study demonstrated a significant reduction of insulin and oral medications and A1C reduction with ketogenic approaches while demonstrating a high adherence to the intervention at 12 months.[23][24] Also markers of cardiometabolic risk factors improved.[25]  Approaches to nutritional lifestyle approaches to diabetes, (medical nutrition therapy) have included low carb as an option in recent guidelines.[26][27]  Recent prospective and randomized controlled trials have demonstrated a consistent benefit in glycemic control, weight loss and sustained medication reduction using a very low carb approach (< 14% of energy from carbohydrates).[28][29][30]

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.
“The long-term effect of carbohydrate restriction is still controversial, especially with regard to its influence on cardiovascular disease,” said Xiaodong Zhuang, MD, PhD, a cardiologist at the hospital affiliated with Sun Yat-Sen University in Guangzhou, China, and the study’s lead author. “Considering the potential influence on arrhythmia, our study suggests this popular weight control method should be recommended cautiously.”

So, with my sister-in-law as my Whole30 guide, I successfully followed the program for the entire month of November. The beginning was really bumpy for me — I am truly an emotional eater and I am absolutely addicted to sugar. But once it was done, it was clear to me that the benefits outweighed the challenges. I now have a whole new understanding and respect for my body and a newfound control over the food I put in my mouth. Full disclosure that the Whole30 diet affects everyone differently, but here are the seven biggest changes I saw in myself after 30 days:
Ketogenic diets have been used by doctors to treat patients with epilepsy and metabolic conditions since the 1920s! They have well-documented benefits, including helping to treat epilepsy, promoting rapid weight loss and reducing diabetes risk. Not only have studies over the past century shown that the keto diet can reduce the amount of seizures patients suffer from, but it can also have positive effects on body fat, blood sugar, cholesterol levels, hunger levels and neurological health. (1)

Leptin and ghrelin are two hormones that have been recognized to have a major influence on energy balance. Leptin is a mediator of long-term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Ghrelin on the other hand is a fast-acting hormone, seemingly playing a role in meal initiation. As a growing number of people suffer from obesity, understanding the mechanisms by which various hormones and neurotransmitters have influence on energy balance has been a subject of intensive research. It is now established that obese patients are leptin-resistant. (13)
Before medications, carbohydrate control has been the cornerstone of glycemic control in both type 1 and type 2 diabetes.  Dietary carbohydrates increase insulin needs, and reduction of carbohydrate intake can improve glycemic control.[22]  A recent study demonstrated a significant reduction of insulin and oral medications and A1C reduction with ketogenic approaches while demonstrating a high adherence to the intervention at 12 months.[23][24] Also markers of cardiometabolic risk factors improved.[25]  Approaches to nutritional lifestyle approaches to diabetes, (medical nutrition therapy) have included low carb as an option in recent guidelines.[26][27]  Recent prospective and randomized controlled trials have demonstrated a consistent benefit in glycemic control, weight loss and sustained medication reduction using a very low carb approach (< 14% of energy from carbohydrates).[28][29][30]
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.

This book was a surprise hit for me! I’ll be honest, I wasn’t expecting much, and only bought it because I was actually doing a Whole30 in January 2017 (it went great! I recommend it—I assume you’re thinking about it if you’re reading this review). We’ve been vegetarian for about 7 years, so eating and cooking so much meat, well, let’s just say I needed some help. The first thing I was impressed with? The recipes are very creative! They are easy to follow, don’t take a lot of time (I have a baby and a toddler and work from home), I particularly loved the slow-cooker recipes that make extra (beef roast, etc) that is then used for different recipes later in the week. Genius!


Kephart WC, Pledge CD, Roberson PA, Mumford PW, Romero MA, Mobley CB, Martin JS, Young KC, Lowery RP, Wilson JM, Huggins KW, Roberts MD. The Three-Month Effects of a Ketogenic Diet on Body Composition, Blood Parameters, and Performance Metrics in CrossFit Trainees: A Pilot Study. Sports (Basel). 2018 Jan 09;6(1) [PMC free article: PMC5969192] [PubMed: 29910305]
In a 2005 study published in The Upsala Journal of Medical Science, for two groups of obese patients with type 2 diabetes, the effects of two different diet compositions were tested with regard to glycemic control and body weight. A group of 16 obese patients with type 2 diabetes was put on a low-carb diet (1,800 calories for men and 1,600 calories for women) that consisted of 20 percent carbohydrates, 30 percent protein and 50 percent fat.
However, data from certain clinical trials has shown that low-carb diets, even very low-carb ketogenic diets, can actually help improve mood and reduce fatigue and hunger. A 2007 study conducted by the Department of Psychiatry and Behavioral Sciences at Duke University Medical Center found that participants experienced significant improvements in a broad range of negative symptoms when following a very low-carb diet, even more so than participants following a low-fat diet. Those on the very low-carb reported less fatigue, cognitive symptoms, physical effects of hunger, insomnia and stomach problems than the low-fat diet group. (4)
The Paleo diet is the healthiest way you can eat because it is the ONLY nutritional approach that works with your genetics to help you stay lean, strong and energetic! Research in biology, biochemistry, Ophthalmology, Dermatology and many other disciplines indicate it is our modern diet, full of refined foods, trans fats and sugar, that is at the root of degenerative diseases such as obesity, cancer, diabetes, heart disease, Parkinson’s, Alzheimer’s, depression and infertility. – Robb Wolf
