According to the model from the evolutionary discordance hypothesis, "[M]any chronic diseases and degenerative conditions evident in modern Western populations have arisen because of a mismatch between Stone Age genes and modern lifestyles." Advocates of the modern Paleo diet have formed their dietary recommendations based on this hypothesis. They argue that modern humans should follow a diet that is nutritionally closer to that of their Paleolithic ancestors.
Tens of thousands of people have taken on the Whole30 program, a monthlong clean-eating program that promises a bevy of health and emotional benefits. Developed by Dallas and Melissa Hartwig, a husband-and-wife team with backgrounds in sports nutrition, anatomy, and physical therapy, the program aims to reset your metabolism and reshape your relationship with food.
I cannot possibly put enough emphasis on this simple fact—the next 30 days will change your life. It will change the way you think about food. It will change your tastes. It will change your habits and your cravings. It will restore a healthy emotional relationship with food, and with your body. It has the potential to change the way you eat for the rest of your life. I know this because I did it, and millions of people have done it since, and it changed my life (and their lives) in a dramatic and permanent fashion.
On Day 4, I reached for a beef jerky stick from Epic. I simultaneously took a big bite while turning over the packaging to read the label. When I saw it on the ingredients list, I stopped mid-chew: "honey." I immediately spit the partially chewed jerky in my garbage can. Close one. After that, I always read the labels on my food twice before eating a morsel.
Why so strict? According to the diet's founders, Melissa and Dallas Hartwig, these are the foods that are most likely to cause inflammation and gut damage. They're also the foods that the founders say destabilize blood sugar levels and lead to cravings. But it's hard to say whether that's true for everyone. In general, limiting sugar and alcohol is always a good idea. But dairy, grains, and legumes? They don't trigger an inflammatory response in everyone, Haas says.
No background science here or lengthy explanations, only 15 easy guidelines to follow to kick-start your Paleo journey. It’s up to you to decide to what extent you want to follow those guidelines, but if you follow them 100% you can be assured that you are eating the best food for your body and greatly investing in your long term health and well-being.
For example, POUNDS LOST (Preventing Overweight Using Novel Dietary Strategies), a two-year head-to-head trial comparing different weight loss strategies, found that healthy diets that varied in the proportions of different macronutrients (carbohydrates, protein and fats) worked equally well in the long run, and that there was no speed advantage for one diet over another.

Realistic Details: I think that this will be more challenging if your culinary experience is limited. A lot of people complain about the difficulty of the recipes. The fact is that if you can make eggs and broil or barbecue meat, or even if you can turn on an oven and toss a salad, you will be fine. You might be a little bored with the food if you are not savvy in the kitchen, but it might help if you are really a novice to get the cookbook in addition to the guide.
My fiancee and I did this together. It takes teamwork (if you have a family, you probably need to get them on board). It also will help if you can begin (or even complete) this diet when you have a minimum of social obligations--having office mates who eat a lot of cake or friends who drink a lot of booze WILL NOT HELP while you are on this program. Don't try to start this the week before Christmas if your family gathers to eat until they pass out. Be realistic about when you begin this. You must prepare a little bit and read the book ahead of time so you aren't just floating at sea. And, be aware: you will not be able to sufficiently screen foods made by other people!

Carbohydrates, protein, and fat are macronutrients and they give your body calories. Each one has their own properties based on the composition of their elements (each having a unique mixture and structure of carbon, hydrogen, and oxygen), and other chemicals that make up the specific molecules. Each one plays a different role in your body and gives a different amount of calories per gram (4 per gram of protein or carbohydrate, and 9 per gram of fat). There's a huge and technical listing of things that each one does and how they function, and their relation to each other and every other element of your nutrition, especially when you start talking about the different kinds of carbohydrates, protein, and fat. The short version is that fat is used by your body to maintain things like your skin, hair, fingernails and teeth, protein is used to build and maintain muscles, some internal organs, and the like. Normally, carbohydrates are used to fuel everything else, especially your nervous system and your brain. However, although blood glucose is necessary, there is no "essential" carbohydrate, meaning that it is possible to live without ingesting a single gram. Glucose is created by the liver from other substrate through a process known as gluconeogenesis. Most, but not all, of the proteins and fats your body needs can be synthesised by your body from other available macronutrients; the few that can't be are called essential amino acids and essential fatty acids, respectively.
The Carnitine Miracle by Robert Crayhon, M.S. The nutrient carnitine is abundant in red meat. According to Crayhon carnitine helps balance blood lipids and blood sugar levels, maximizes energy levels, increases endurance, eliminates discomfort in ketosis, promotes burning of fat and building of muscle and increases overall well-being.

Ideally one should eat a wide variety of proteins from as many animal sources as possible. One need not and should not avoid fatty cuts of meat, particularly if consuming pastured sources. An often overlooked piece of the paleo diet in popular culture is an over-reliance on standard cuts of meat, at the expense of organ meats, bone broth and other collagen sources. For more information on the historical and practical aspects of consuming a more balanced protein intake, check out the Weston A. Price Foundation. If weight-loss is a goal, protein makes you feel satisfied between meals.
The study involved 164 overweight adults who first underwent a weight-loss regimen in order to lose around 10 percent of their body weight. Then, they were randomly assigned to follow a low-, moderate- or high-carbohydrate diet — with 20, 40 or 60 percent of their calories coming from carbs, respectively — for 20 weeks. The low-carb group also consumed a higher amount of fat, but all groups consumed about the same amount of protein, sodium and added sugar. All of the participants were provided with fully prepared meals to ensure they were consuming these precise levels of nutrients.
Sex With Your Pants On (SWYPO) is a term used to describe the idea of recreating treats such as pancakes, brownies, or pizza with Whole30 ingredients, and is strongly cautioned against. The Hartwigs feel that if you’re trying to recreate a pizza made out of cauliflower crust in order to scratch a craving itch, then you’re kind of missing the point. To quote the Whole30 website, “You can tell yourself it’s okay, it’s still pretty good, you’re totally satisfied … but that’s kind of a lie. Because you know exactly how good pants-less sex feels.”
Basically, yes and no. Low-carb diets can lower your body weight faster than low-energy diets, but not without cost. Your body needs energy to survive, just as any nutrient in food, and carbohydrates provide it as the most convenient form. Getting the energy from proteins really doesn't make a whole lot of sense if you look at it in terms of our evolutionary history. Early humans (in the Paleolithic period) were generally agreed to be long distance runners, who would chase animals till they died of exhaustion, or became paralyzed by heat stroke and could not run or fight when caught up with by their hunters. Humans are one of the few species that are able to run for long distances at close to max speed, and we used this to chase prey animals 15-20 miles until we could just club them to death. This is, first of all, not a method of hunting that lends itself to a high protein diet. And as any long distance runner or cyclist will tell you, you need carbs a lot more than you need protein when you're doing a long run.
So you can imagine that their stance on cheating in the program is very stringent. If you cheat, you’re supposed to start again at day one with no exceptions. As an intense perfectionist in life, this scared me more than any other rule or dietary restriction. And to be fair, I think that any dietary change is hard. Maybe it’s not like quitting heroin, but it’s also not like a spa massage. Did I mention that I also don’t like when people tell me what to do? As a really small child, I stabbed myself in the eye with a fork because my mom told me not to. Yeah … tough love isn’t my love language. Life is complicated.
A low-carbohydrate diet has been found to reduce endurance capacity for intense exercise efforts, and depleted muscle glycogen following such efforts is only slowly replenished if a low-carbohydrate diet is taken. Inadequate carbohydrate intake during athletic training causes metabolic acidosis, which may be responsible for the impaired performance which has been observed.

Furthermore, the practicality of maintaining these interventions over long periods of time is doubtful.
Wheat Belly: Lose the Wheat, Lose the Weight, and Find Your Path Back to Health by William Davis, MD. A renowned cardiologist explains how eliminating wheat from our diets can prevent fat storage, shrink unsightly "wheat belly" bulges, and reverse myriad health problems, like minor rashes and high blood sugar. The author contends that every single human will experience health improvement by giving up modern wheat. The book provides readers with a user-friendly, step-by-step plan to navigate a new, wheat-free lifestyle. Informed by cutting-edge science and nutrition, along with case studies from men and women who have experienced life-changing transformations in their health after waving goodbye to wheat.

Cordain explains that high intake of fruits and vegetables is one of best ways to reduce chances of cancer and heart disease. He notes that protein has twice the calorie burning effect of fat and carbs and is more satiating than both. He explains that starch, fats, sugars, and salts together cause us to keep eating. So if we limit our diet to fruits and vegetables and/or meat, we’ll stop eating when we’re full. And if you stop eating when you’re full, you’ll lose weight and won’t get fat. And as you lose weight, your cholesterol will improve (regardless of what you eat). This all makes sense and can’t really be disputed. If you want to lose weight, the Paleo diet will get you there and probably quickly. But Cordain’s hypothesis applied to long-term health falls short.
Another new study on carbohydrates from Harvard found that middle-of-the-roaders who kept their carbohydrate intake to 50% or 55% of total calories were the likeliest to live the longest. Those researchers evaluated dietary records completed by more than 15,000 U.S. adults, ages 45 to 64, between 1987 and 1989. During the 25-year follow-up, they found that the moderate carb eaters, staying at 50% to 55%, were less likely to die than both the low-carb eaters (in this study, less than 40%) and the high-carb eaters (in this study, more than 70%).
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 NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
The good news is that you'll find yourself craving your junky favorites less as time goes on. But that first week can be notoriously tough as your body transitions to a cleaner way of eating. Now more than ever, make sure you're eating regular, balanced meals and keeping approved snacks like plantain chips with salsa and celery sticks with almond butter on hand. It's always easier to say no to cookies or chips when you're satisfied from eating something clean and delicious—or have another snack or dish to look forward to.
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.
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.
As University of California-Davis food chemist Bruce German told Pollan in an interview, “You could not survive on wheat flour. But you can survive on bread.” Microbes start to digest the grains, breaking them down in ways that free up more of the healthful parts. If bread is compared to another method of cooking flour—basically making it into porridge—”bread is dramatically more nutritious,” says Pollan.
First, I’d just like to acknowledge that I’m not a nutritionist or a healthcare professional. The opinions I share here are simply my own experiences and thoughts while trying this program. I also acknowledge that the topics of healthy eating, dieting, and illness are very personal, and what might work for me, might not work for someone else. We are all unique.
“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.”

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.
4. Raw food is for the birds (too much of it, anyway). There’s paleo, and then there’s the raw diet. Folks who eat raw tout the health benefits of the approach, saying that they’re accessing the full, complete nutrients available because they’re not heating, and thus destroying, their dinner. But that’s simply wrong. We cook to get our hands on more nutrients, not fewer. According to Wrangham, the one thing absolutely all cultures have in common is that they cook their food. He points out that women who move towards 100 percent raw diets often stop ovulating, because even if in theory they’re tossing sufficient food into the blender to fulfill their caloric needs, they simply can’t absorb enough from the uncooked food.
I understand the time constraints and the amount that he does but I wish that he didn't get so lazy at the end. Seemed disinterested. I get it but he is selling this book. I liked the journaling overall and gave good insight into the games process. I am curious about his thoughts and how he will handle this new setup for the games. It does not sound like any of these changes this year were even thought of a year ago.
Cutting out starchy foods, or any food group, can be bad for your health because you could be missing out on a range of nutrients. Low-carbohydrate diets tend to be high in fat, and eating a diet that is high in fat (especially saturated fat from foods such as meat, cheese, butter and cakes) could increase your chances of developing coronary heart disease.
The paleo diet is hot. Those who follow it are attempting, they say, to mimic our ancient ancestors—minus the animal-skin fashions and the total lack of technology, of course. The adherents eschew what they believe comes from modern agriculture (wheat, dairy, legumes, for instance) and rely instead on meals full of meat, nuts, and vegetables—foods they claim are closer to what hunter-gatherers ate.
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.
Outside of this new study, I haven’t found the evidence for the low-carb diet compelling. But maybe I’m too biased by my love of pasta, bread, and cake — and my personal experiences failing to restrict my carb intake — to fully embrace low-carb living. (In fact, my losing weight over the long term coincided with eating more carbs than ever before.)
In general, a low-carb diet focuses on proteins, including meat, poultry, fish and eggs, and some nonstarchy vegetables. A low-carb diet generally excludes or limits most grains, legumes, fruits, breads, sweets, pastas and starchy vegetables, and sometimes nuts and seeds. Some low-carb diet plans allow small amounts of certain fruits, vegetables and whole grains.
These researchers point out that there are plenty of reasons to suggest that the low-fat-is-good-health hypothesis has now effectively failed the test of time. In particular, that we are in the midst of an obesity epidemic that started around the early 1980’s, and that this was coincident with the rise of the low-fat dogma. (Type 2 diabetes, the most common form of the disease, also rose significantly through this period.)
