Proponents of the Paleo diet follow a nutritional plan based on the eating habits of our ancestors in the Paleolithic period, between 2.5 million and 10,000 years ago. Before agriculture and industry, humans presumably lived as hunter–gatherers: picking berry after berry off of bushes; digging up tumescent tubers; chasing mammals to the point of exhaustion; scavenging meat, fat and organs from animals that larger predators had killed; and eventually learning to fish with lines and hooks and hunt with spears, nets, bows and arrows.
Research into the weight loss effects of the paleolithic diet has generally been of poor quality.[10] One trial of obese postmenopausal women found improvements in weight and fat loss after six months, but the benefits had ceased by 24 months; side effects among participants included "weakness, diarrhea, and headaches".[10] In general, any weight loss caused by the diet is merely the result of calorie restriction, rather than a special feature of the diet itself.[10]
The Dietary Guidelines for Americans recommends eating a moderate amount of carbs -- about 45% to 65% of your total daily calories. If you eat 2,000 calories a day, your carbs on this moderate plan should total about 900 to 1,300 calories, or about 225 to 325 grams a day. (A slice of whole wheat bread has 12 grams or more of carbs; a single 6-inch pancake, 30.)
For immediate weight loss, Paleo is a great and healthy solution. But after carefully reading and considering, I’m unconvinced that Paleo is optimal for long-term health. I think, in fact, it might lead to heart disease and other ills associated with heavy meat consumption. Although many of Cordain’s theories fall apart long-term, I thoroughly enjoyed the read and highly recommend the book. You should read critically and decide for yourself.
Life Without Bread: How a Low-Carbohydrate Diet Can Save Your Life by Christian B. Allan, Wolfgang Lutz. It is based on Dr. Lutz's work with thousands of patients in Austria. It deals with the health issues connected to high carb consumption. It is basically an English version and update of Dr. Lutz's 1967 book with the same title: Leben ohne Brot. He recommends eating only 72 grams of carbohydrates, and an unlimited amount of fat. And provides evidence as to why this is the healthiest diet. Read the review at Amazon by Todd Moody (it will be first!). See excerpts from his earlier edition: Dismantling a Myth: The Role of Fat and Carbohydrates in our Diet
On this diet, you’ll be led through four phases. First, you’ll focus on foods high in protein, and then add vegetables back in, followed by gradually introducing more carb-containing foods foods, like fruit and whole-grain bread, plus an allowance of two celebration meals per week. In the final phase, you’ll aim to maintain your weight loss results by eating foods from all food groups, supplementing with oat bran, and fitting in fitness daily.
A crucial difference between different kinds of carbohydrates is how rapidly they're broken down and absorbed into the blood stream, and how "sharp" a spike in blood sugar one experiences after eating them. The glycemic index is one (popular) attempt to quantify this. The glycemic index of a particular foodstuff is calculated by making test subjects eat an amount of the foodstuff that contains 50 grams of total carbohydrate; the subjects' blood glucose is then measured at regular intervals over the next two hours, and the glycemic index is derived from the size of the response curve. Unfortunately, the glycemic index isn't scaled for a reasonable portion size; measuring the G.I. of carrots, for example, requires the test subject to eat a pound and a half of carrots. A more sane quantity, called the glycemic load, is scaled for portion size, but glycemic load data are much more difficult to come by than glycemic index data.

If you have been in a state of dependency on food--be it sugars, alcohol, chips, ice cream, just about anything--or if you have been unwell, unsuited to the world physically or emotionally--or, if you simply feel blah and would like to lose a little bit of weight--please consider trying this program. You might think, "I don't eat that badly! I eat a lot of whole foods!" which is what most people think of themselves (I sure did). But when you actually make a conscious decision to eliminate foods from your diet, you will see that even the small amounts of crap that you've been eating regularly matter. Prepare to be amazed. I sound like an evangelical, I know. It's a little embarrassing. But it is all true.


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.
A better idea is to reincorporate small amounts of non-Whole30 foods one at a time, waiting a few days before adding something else back in. For instance, after day 30, continue to follow the diet, but have yogurt for breakfast and add some cheese to your salad. Do this for a few days and see if any symptoms pop up. If they do, you know that dairy is problematic for you. Then, try the same thing with another food group, like gluten-free grains. Reintroducing gluten-free and gluten-containing grains separately can help you determine whether you have a gluten sensitivity.
In that sense, Whole30 has been so helpful in understanding my body. So how am I eating now? I would say that I'm eating pretty "paleo" these days. I definitely still indulge once in a while, with some red wine or french fries, but I haven't been tempted to binge in the slightest. I would definitely do Whole30 again, but I need a bit of a break from it at the moment. Instead, I'm ready for a mindful and moderate approach to my new chapter of life, back in New York City.
Once you've got your meals and snacks mapped out, make a grocery list and hit the store. Doing one big shop ensures that you'll have everything on hand for the week, so there's no last-minute scrambling. Be sure to read ingredient labels carefully in the packaged foods you buy. For example, some almond milks have carrageenan, an unapproved emulsifier, soy sauce has traces of gluten, and deli meats have preservatives.
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 that nutritional philosophy and strongly disagree with the conclusions drawn from that book [7], and will leave you to make your own conclusions based on your own self-experimentation.
The keto diet is centered on fats, which constitute anywhere from 70-80% of a dieter's daily calories. People who adopt a keto lifestyle often drink coffee black (or add some fatty butter to their brew), chew salads without too many carrots or apples inside, and trade traditional pizza crusts and pastas for cauliflower "breads" and zucchini "noodles."

Now, The Whole30 offers a stand-alone, step-by-step plan to break unhealthy habits, reduce cravings, improve digestion, and strengthen your immune system. The Whole30 prepares participants for the program in five easy steps, previews a typical thirty days, teaches the basic meal preparation and cooking skills needed to succeed, and provides a month’s worth of recipes designed to build confidence in the kitchen and inspire the taste buds. Motivating and inspiring with just the right amount of signature tough love, The Whole30 features real-life success stories, an extensive quick-reference FAQ, detailed elimination and reintroduction guidelines, and more than 100 recipes using familiar ingredients, from simple one-pot meals to complete dinner party menus.
The data for Cordain's book only came from six contemporary hunter-gatherer groups, mainly living in marginal habitats.[37] One of the studies was on the !Kung, whose diet was recorded for a single month, and one was on the Inuit.[37][38][39] Due to these limitations, the book has been criticized as painting an incomplete picture of the diets of Paleolithic humans.[37] It has been noted that the rationale for the diet does not adequately account for the fact that, due to the pressures of artificial selection, most modern domesticated plants and animals differ drastically from their Paleolithic ancestors; likewise, their nutritional profiles are very different from their ancient counterparts. For example, wild almonds produce potentially fatal levels of cyanide, but this trait has been bred out of domesticated varieties using artificial selection. Many vegetables, such as broccoli, did not exist in the Paleolithic period; broccoli, cabbage, cauliflower, and kale are modern cultivars of the ancient species Brassica oleracea.[29]
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.

In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.
There’s no official guideline that defines a low-carb diet, says Schmidt. But generally speaking, consuming about 50 to 100 g of carbs a day is considered a basic low-carb diet, she says. That said, it can be more — it’s all about eating fewer carbs than is normal for you. The perk of this plan is it’s individualized, allowing you to eat the amount that best meets your body’s needs. It also gives you leeway to choose what carbs you want to include (fruits, vegetables, dairy, whole grains, nuts, and seeds) rather than being on a plan that tells you what you need to eat and when. It’s best for someone who likes that freedom, and doesn’t want to spend the time counting grams of carbs.
Super easy read. Enjoyed hearing some back stories we’d never know about if we didn’t read book. Made me appreciate how much thought, emotion (from how it looks from spectator view), and timing goes into what Dave does. Say what you want, Dave Castro is a brilliant, empathetic, and no bullshit kind of dude. Bucket list: have a beer with the Castro!
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.
Another downside: If you have had chronic health issues (especially gut related), you may find that reintroduction actually teaches you that you're sensitive to most foods. It turns out peanut butter, gluten, and most dairy are now off limits. That rots!! But I'll live. I feel so, so much better without them, as I learned. And wouldn't you rather know why you feel crappy all the time?
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.

As for qualifying, competing, and the works, here’s what we know in a quick synopsis. This year at the Games, there will be well over 300 individual athletes that will be competing. The top two athletes (man/woman) that finish in their country will earn a spot to the Games (only countries with affiliates count, there are 162 currently), the first place finishers of Qualifiers earn a spot (16 qualifiers = 32 winners), and the top 20 Open finishers earn a spot.

But listen--we'd both been relatively inactive for years and each about 25 pounds overweight. Between the two of us we lost 34 lbs in 30 days and we are still going to keep up a serious commitment to Whole 30, with a few supplemental treats now and then. We feel better, we have new confidence about getting dressed in the morning, and we're more fit than in years, mostly because we have the energy to do more. The amazing thing is that you will NOT feel hungry if you hang in there and consistently prepare foods as per the cookbook/menus. There is also a very supportive and helpful forum online to supplement the book.

Is the egg diet effective? There are several versions of the egg diet, all of which involve eating eggs as the main source of protein and restricting other foods. Eggs contain many nutrients, and the diet may help people lose weight. However, they contain no fiber, and they can be high in cholesterol. Find out more about the pros and cons. Read now

The difference from other low-carb diets is that you’re going to swap saturated fats for unsaturated fats — a plus if you have type 2 diabetes, which leaves you more at risk for heart disease, or if you have a personal or family history of heart disease yourself. That means rather than butter, cheese, and cream, you’re eating olive oil, fatty fish, nuts, seeds, and avocado as your main sources of fat.
The rationale for the Paleolithic diet derives from proponents' claims relating to evolutionary medicine.[22] Advocates of the diet state that humans were genetically adapted to eating specifically those foods that were readily available to them in their local environments. These foods therefore shaped the nutritional needs of Paleolithic humans. They argue that the physiology and metabolism of modern humans have changed little since the Paleolithic era.[23] Natural selection is a long process, and the cultural and lifestyle changes introduced by western culture have occurred quickly. The argument is that modern humans have therefore not been able to adapt to the new circumstances.[24] The agricultural revolution brought the addition of grains and dairy to the diet.[25]

Update: So I just finished Day 23 of my Whole30 Journey and I feel good, aside from the fact that I caught a cold. Weighing myself today, I discovered that I lost 19.5 pounds so far! I measured myself and immediately noted that I lost 19 inches over all (I measure my chest, both arms, both legs, waist, and hips). I think when I am done with my first round, I'll take a day off then start a second round. I just feel that great overall.
And because the study was 20 weeks, the long-term effects of the specific low-carb diet followed in the study — such as risks for heart disease or overall mortality — are not known, Hunnes added. (A recent study found that people who consumed both high- or low-carb diets were at greater risk for early death, compared with those who consumed a moderate-carbohydrate diet.)

Carbohydrate-restricted diets can be as effective, or marginally more effective, than low-fat diets in helping achieve weight loss in the short term.[4] In the long term, effective weight maintenance depends on calorie restriction, not the ratio of macronutrients in a diet.[5] The hypothesis proposed by diet advocates that carbohydrate causes undue fat accumulation via the medium of insulin, and that low-carbohydrate diets have a "metabolic advantage", has been falsified by experiment.[6][4]

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.
We cannot time travel and join our Paleo ancestors by the campfire as they prepare to eat; likewise, shards of ancient pottery and fossilized teeth can tell us only so much. If we compare the diets of so-called modern hunter-gatherers, however, we see just how difficult it is to find meaningful commonalities and extract useful dietary guidelines from their disparate lives (see infographic). Which hunter–gatherer tribe are we supposed to mimic, exactly? How do we reconcile the Inuit diet—mostly the flesh of sea mammals—with the more varied plant and land animal diet of the Hadza or !Kung? Chucking the many different hunter–gather diets into a blender to come up with some kind of quintessential smoothie is a little ridiculous. "Too often modern health problems are portrayed as the result of eating 'bad' foods that are departures from the natural human diet…This is a fundamentally flawed approach to assessing human nutritional needs," Leonard wrote. "Our species was not designed to subsist on a single, optimal diet. What is remarkable about human beings is the extraordinary variety of what we eat. We have been able to thrive in almost every ecosystem on the Earth, consuming diets ranging from almost all animal foods among populations of the Arctic to primarily tubers and cereal grains among populations in the high Andes.”

Our bodies need much more protein than the average person consumes. In fact, protein accounts for only 15 percent of the average person’s daily calories, while 19 to 35 percent of the average hunter-gatherer diet was comprised of protein. This was due to the high consumption of meat, seafood, and other animal products prevalent in contemporary approaches to Paleo eating.
