The following links tend towards news reports of scientific studies that point out some positive aspect of the paleo diet. If you are looking for current news reports, I suggest signing up for Google Alerts for the Type: News. I have three set up, for: "caveman diet," "paleo diet," and "paleolithic diet." You can also set them up for blogs and/or websites.

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.
Fattening cattle with corn changes the lipid balance and is clearly not the natural diet for a grass eating cow. In Simple change in cattle diets could cut E. coli infection researchers have found that when cattle were fed hay or grass for just five days before slaughter, much less E. Coli cells were present in the animal's feces and virtually all surviving E. coli bacteria were not acid-resistant and were killed by human stomach acid.

The British Dietetic Association (BDA) today revealed its much-anticipated annual list of celebrity diets to avoid in 2018. The line-up this year includes Raw Vegan, Alkaline, Pioppi and Ketogenic diets as well as Katie Price's Nutritional Supplements.
Prior to starting, athletes should state their name, and show and state the weights and equipment to be used. All video submissions must be uncut and unedited in order to accurately display the performance. A clock or timer, with the running workout time clearly visible should be in the frame throughout the entire workout. Shoot the video from an angle so ALL exercises can be clearly seen meeting the movement standards. Videos shot with a fisheye lens or similar lens may be rejected due to the visual distortion these lenses cause. If an athlete needs someone to adjust their camera during the WOD to capture all movements, this is acceptable, as long as the flow of the workout and the athlete is in view the whole time.
Fresh fruits, fresh vegetables, fresh meat—the paleo diet is all about eating foods straight from the Earth just as our ancestors did. Those ancestors didn't have livestock or crops to call their own, so Cordain advises to go with grass-fed and organic varieties whenever possible to limit exposure to pesticides, antibiotics, and other chemicals that didn't exist back then. Research from Emory University suggests that Paleolithic people obtained about 35% of their calories from fats, 35% from carbohydrates, and 30% from protein.
In July 2016, a New York Times article on use of Instagram by dieters noted that participants in the Whole30 program had shared over one million Instagram posts using the #Whole30 hashtag, and noted that those sharing the tag were "one of seemingly endless like-minded communities," comparing it with the over 3.5 million posts under the #WeightWatchers hashtag.[11]
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.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soyfoods, and peanuts. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.
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.
Paleonutrition by Mark Q. Sutton, Kristin D. Sobolik, and Jill K. Gardner is the analysis of prehistoric human diets and the interpretation of dietary intake in relation to health and nutrition. This is a substantial text that combines background to paleonutrition, an extensive bibliography, a discussion on methods, and case studies. Published February 23, 2010.

Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them.[29] Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total expected age of 54 years.[30] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years.[31][32] That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."[33]

These findings were true despite that reductions in body weight, waist circumference and other metabolic risk factors were not significantly different between the two diet groups. These findings suggest that satisfying lower-carb diets, which are higher in fat, can help beat heart disease factors just as well as diets that are harder to stick with and prone to leaving people hungry.

Dukan Diet This option also includes four phases: two weight loss and two maintenance. For instance, the first phase of the Dukan diet focuses on high-protein foods, the second adds vegetables back in, the third allows two “celebration” meals per week, and the fourth is about keeping your weight stable. Because you can follow the diet from the book, it also appeals to people who need a planned approach.


You probably hear the most about low-carb eating for weight loss, but for some people, the approach could also help optimize their health, says Schmidt. “Research shows that women who are obese or have metabolic problems [may] do better hormonally on lower carbs,” says Schmidt, pointing out that other outcomes of the diet can include better sleep, mental clarity, and increased satiety.

Hi, I have been giving ditch the carbs a go…so far only in the form of bread,pasta,rice, this was quiet hard for me as I didn’t realise how much I got through a day! I’m a fussy meat eater as I was a veggie for a number of years so still only eating veggie quorn. I don’t drink fizzy drinks or alcohol. I have already cut out cakes/biscuits apart from the odd biscuit! I have lost weight and I still need to loose more…I really want to change my children’s diet also but I have one child who will eat/try anything and a two year old who won’t eat vegetables, luckily she has never been keen on pasta,rice or potatoes anyway but think I will struggle with her…so any tips welcome! She loves all fruit which I let her have as she doesn’t eat veggies but not sure if this is wise!
If you were to eat an unlimited amount of red meat (which the paleo diet technically allows), you may see your heart health suffer. While experts applaud the omission of packaged and processed foods like cake, cookies, chips, and candy — which are well known to be bad for your ticker — they’re not crazy about the fact that paleo doesn’t allow you to eat whole grains, legumes, and most dairy. Whole grains in particular have been linked with better cholesterol levels, as well as a reduced risk of stroke, obesity, and type 2 diabetes. (13) These are all comorbidities of heart disease. (14)
Use fat as a lever.  We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
With funding from the Laura and John Arnold Foundation, in 2012 Taubes co-founded the Nutrition Science Initiative (NuSI), with the aim of raising over $200 million to undertake a "Manhattan Project for nutrition" and validate the hypothesis.[29][30] Intermediate results, published in the American Journal of Clinical Nutrition did not provide convincing evidence of any advantage to a low-carbohydrate diet as compared to diets of other composition – ultimately a very low-calorie, ketogenic diet (of 5% carbohydrate) "was not associated with significant loss of fat mass" compared to a non-specialized diet with the same calories; there was no useful "metabolic advantage".[6][8] In 2017 Kevin Hall, a NIH researcher hired to assist with the project, wrote that the carbohydrate-insulin hypothesis had been falsified by experiment.[28][8] Hall wrote "the rise in obesity prevalence may be primarily due to increased consumption of refined carbohydrates, but the mechanisms are likely to be quite different from those proposed by the carbohydrate–insulin model".[8]
Following the paleo diet can be pricey. Inexpensive and healthy non-meat protein sources like soy and beans are off-limits, and a recent BMJ Open study shows that healthy meats like lean ground beef and boneless, skinless chicken breasts cost an average of 29 cents more per serving compared to less-healthy ones, such as high-fat ground beef and chicken drumsticks. Even switching from peanut butter to paleo-approved almond butter will cost you—it goes for up to $13 a jar.
2) There is a big step up in the use of tree nuts in the cookbook. I never really got why tree nuts would be included in an anti-inflammatory diet when they are one of the more common allergens. Aside from that, I'm super allergic to tree nuts (need an epi-pen) so this was, personally, lame for me. Nuts were easy to avoid in 30 Day Guide but many more recipes include them in the cookbook.
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.
Don't try to cut out carbs completely. Remember its a 'low-carb diet', not a 'no-carb diet'. So, "don’t try to cut out all sources of carbs because your body needs carbohydrates to function. Your brain, for example, uses the carbohydrate glucose as a primary fuel," notes Gorin. Meanwhile, "naturally occurring carbohydrates like the ones found in whole grains, milk, yogurt, fruits and vegetables provide important nutrients like fiber — which helps improve satiety and may reduce cholesterol levels," she says. Work on limiting carbs that aren’t beneficial to you — think processed foods like frozen pizzas, white bread, pastries, store-bought fruit juices, etc.
"The struggle is a normal, necessary part of the process. Changing your food is hard. Changing your habits is even harder. Changing your relationship with food is the hardest part of all. The process requires struggle—it’s how you know you’re growing—but don’t make it harder than it has to be! There is no such thing as the 'perfect Whole30,' so if your beef isn’t grass-fed or your travel meal doesn’t look exactly like our meal template, don’t sweat it. Your only job is to stick to the Whole30 rules for 30 days, and some days, you’ll have to let good enough be good enough. When you do struggle, remember why you took on the program in the first place, and don’t be overwhelmed by the big picture—just focus on the next day, or the next meal. Don’t be afraid to ask for help when you need it, and high-five yourself for the victories you’re achieving every day you’re on the program, no matter how small. Even tiny progress is progress."
Fifteen obese diabetes patients were put on a high-carbohydrate diet to serve as the control group. Their diet consisting of the same calories for men and women included approximately 60 percent carbohydrates, 15 percent protein and 25 percent fat. Positive effects on the glucose levels were seen very quickly in the group following the low-carb plan. After six months, a marked reduction in body weight of patients in the low-carb diet group was also observed, and this remained one year later. (10)
Choosing quantity over quality. One of the most common mistakes people make while on a low-carb diet is that they reduce their carb intake so much that they end up feeling starved.  Consequently, they fall off the wagon and regain weight. Rather than aiming for a fixed amount of carbs, work on eliminating bad carbs from your diet, says Ward. Think soft drinks, cereals, packaged juices, etc. And fill up on better carbohydrate options such as beans, pulses, fruit, whole grains and starchy vegetables, she suggests.

This is not hard. Don’t you dare tell us this is hard. Fighting cancer is hard. Birthing a baby is hard. Losing a parent is hard. Drinking your coffee black. Is. Not. Hard. You’ve done harder things than this, and you have no excuse not to complete the program as written. It’s only thirty days, and it’s for the most important health cause on earth—the only physical body you will ever have in this lifetime.
Of these 50 spices, the essential, most often used ones are coarse sea salt, cracked pepper, smoked paprika, Italian seasoning, fennel seeds, cayenne, onion granules, garlic granules and ground cumin. However, you better have ras el hanout (or the spices to blend it) because it was hands-down the best chicken I’ve ever had (Moroccan Chicken with Carrot-Pistachio Slaw, page 143). Check out the photos we posted with our review, and don't skip making the accompanying Carrot Slaw!

According to Adrienne Rose Johnson, the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Dr. Emmet Densmore and Dr. John Harvey Kellogg. Densmore proclaimed that "bread is the staff of death", while Kellogg supported a diet of starchy and grain-based foods.[11] The idea of a Paleolithic diet can be traced to a 1975 book by gastroenterologist Walter Voegtlin,[7]:41 which in 1985 was further developed by Stanley Boyd Eaton and Melvin Konner, and popularized by Loren Cordain in his 2002 book The Paleo Diet.[8] The terms caveman diet and stone-age diet are also used,[12] as is Paleo Diet, trademarked by Cordain.[13]
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.

Trick And Treat - how 'healthy eating' is making us ill by Barry Groves. The author is one of the world's most outspoken proponents of a high-fat, low-carbohydrate diet. This book is an account of how and why the health-care establishment has got the concept of 'healthy eating' so wrong. Whereas Taubes work (see above) is a fairly straight forward review of the existing science, Groves expands into the politics of medical research and treatment to a much greater extent. "Trick and Treat" is divided into two parts. Part One describes the corruption in the health industry, points out the problems inherent in a high-carb, low-fat diet, and then prescribes a diet that leads to good health. The prescribed diet is high in fat - specifically animal fat, not polyunsaturated vegetable fat - and low in carbohydrates, with 60-70% of calories from fat, 15-25% of calories from protein, and a mere 10-15% of calories from carbohydrates. Part Two describes numerous diseases the author claims are the result of high carbohydrate consumption. These range from life-threatening disorders such as cardiovascular disease, diabetes, and cancer to less serious problems such as acne, near-sightedness and dental problems. The Amazon reviews average to 4+ stars.
An Interview with Ward Nicholson now has three parts on the web. Good overview of man's diet over the past 65 million years. Long but highly recommended reading. First published in Chet Day's "Health & Beyond" newsletter. Now part of a very comprehensive Beyond Vegetarianism site. Every argument that your vegetarian friends use to avoid meat for health reasons is debunked here.
1) Many of the recipes are complicated, like REALLY complicated. Some requiring as many as 20 ingredients to complete. Others require uncommon ingredients, which will likely not be reused, especially if there isn't another recipe in the book asking for it. Something I appreciated in the 30 Day Guide was that ingredients were frequently used in more than one recipe so they were worth the investment.
Here comes the tough love. This is for those of you who are considering taking on this life-changing month, but aren’t sure you can actually pull it off, cheat free, for a full 30 days. This is for the people who have tried this before, but who “slipped” or “fell off the wagon” or “just HAD to eat (fill in food here) because of this (fill in event here).” This is for you.
Incorporating more fat and protein in response to reduction of dietary carbs has led to concerns on the effect of low-carb dieting on lipids; specifically, LDL cholesterol.  Recent systematic reviews of low-carb diets on lipids demonstrate a neutral to small increase in LDL, but a favorable triglycerides reduction and an increase in HDL cholesterol; particularly those assigned to the very low-carb intervention.[15][16] Although not formally studied, there may be a subset of lean individuals who have a hyper LDL response with ketogenic diets; a term coined Lean Mass Hyper-Responders (https://cholesterolcode.com/lmhr; accessed December 26, 2018). Due to the varied and individualized response, recommendations are for baseline fasting lipid profile, periodic testing and shared decision making.
We want you to be a part of our community. We want you to take this seriously, and see amazing results in unexpected areas. We want you to look, feel, and live better than you have in years—or maybe ever. We want you to find lasting food freedom. Even if you don’t believe this will actually change your life, if you’re willing to give it 30 short days, DO IT. It is that important. We believe in it that much. It changed our lives, and we want it to change yours too.
Hi Cyn, The numbers are general guidelines but will vary depending on many factors, such as activity level, insulin resistance, weight and more. There is no single magic number, just conventional recommendations that are a good starting point. I will have a macro calculator coming soon that will help determine what is best for each person, but even then it’s an approximation. The only way to know for sure is to test. If keto is your goal, it’s usually best to start lower and then see if you can stay in ketosis when increasing.
Whole30 is about a physiological and psychological reset (so, not just about the number on the scale), and if you’re looking to jumpstart your system and make healthier food choices, the 30-day plan may be a good guide for you. “It’s really for someone who is looking to make drastic changes for a short period of time and understands this is a band-aid, not a cure all,” says Zeitlin.

The rationale for the Paleolithic diet derives from proponents' claims relating to evolutionary medicine.[22]:594 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.[22]:594–95 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.[23] The agricultural revolution brought the addition of grains and dairy to the diet.[24]
If you don't have immediate support, join an online forum or support group in which you can share your challenges and achievement. And, when it comes to achievements, mark them, celebrate them, and share them with friends. These are just some of the ways to gain positive reinforcement as you to take the first step to embracing an informed, low-carb lifestyle.

In addition to keeping you adequately hydrated -- which can also help alleviate constipation -- drinking lots of water can also help offset still another low-carb diet problem: bad breath. The ketones produced during the diet can lead to what is sometimes described as a fruity odor although it is often described as having an almost "chemical" odor similar to acetone or nail polish remover.


If you've been on the Whole30 and counting down the days until February 1st, step away from the cheese! Before you transition back to your normal diet, here are five solid lessons that I learned from the eating plan that I stuck with even after the 30 days were up. Not only did following them beyond the 30 days prevent me from rebounding back to my higher weight, but they also help keep me on the straight and narrow the rest of the year when I’m not following the program.
Interest and participation in the event continued to grow, and in 2010, the qualification was adjusted to include hosting multiple Sectionals, a series of events open to all athletes in order to qualify for the one of the 17 Regionals.[8] The 17 regions had Canada and the United States divided into 12 regions, with the remaining regions roughly corresponding the five other populated continents. The attendance at the Games also outgrew the ranch in Aromas and moved the Home Depot Center (later called the StubHub Center) in Carson, California.[9] The Games also expanded the Team Division to groups of six athletes and added a Masters Division for individual men and women 55-years-old and up.

Additionally, “while the paleo diet has plenty of protein and fiber, it is sorely lacking in calcium and vitamin D, mainly because of the omission of dairy products,” Roger Adams, Ph.D., founder of Eat Right Fitness, previously explained to Men's Health. Over time, this could weaken your bones and immune system, which makes it important to eat plenty of calcium-rich (and paleo-friendly) foods like broccoli and dark leafy greens.
A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows. Some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy.
Another mineral you may want to supplement is potassium. While there is no concrete evidence that a dramatic potassium loss occurs on a low-carb regimen, Sondike says to ensure against problems he recommends patients use Morton's Light Salt -- a potassium chloride product that he says can add back any of this important mineral that's lost. Eating a few almonds is also a good way to supplement this mineral without adding carbs to your diet.
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] Any weight loss caused by the diet was merely the result of calorie restriction, rather than a special feature of the diet itself.[10]

One of the most common mistakes people make while on a low-carb diet is that they reduce their carb intake so much that they end up feeling starved.  Consequently, they fall off the wagon and regain weight.

I recognize these drawbacks. But I still kick off the first month of each year by waving goodbye to alcohol, sugar, and yes, the aforementioned healthy food groups. While I've kept the majority of the weight off, I'm still guilty of putting on those extra 4 to 5 pounds throughout the year. But while that would've caused me anxiety before, I'm now okay with it. I enjoy some frozen drinks by the pool during my summer vacation and loosen the reigns a bit during the holidays. Come January 1st, my body desperately wants a break from the late-night holiday parties that cram my calendar from Thanksgiving until New Year's Eve, which is why I do another round of the Whole30. Starting the new year this way helps to reset the habits that I tend to lose track of towards the end of year (moderation and meal-prepping) and it reminds me how good my body feels when I'm treating it right.
The ketogenic diet originally started as a way to control seizures. About 100 years ago, researchers discovered if you deprive the body of glucose from carbohydrates, the brain’s electrical signals relax. And it turns out that when the body uses ketone bodies (ketones) for energy instead of glucose from carbs, you can burn body fat more efficiently.
Several potential mechanisms could explain why restricting carbohydrates might lead to AFib, Zhuang said. One is that people eating a low-carbohydrate diet tend to eat fewer vegetables, fruits and grains—foods that are known to reduce inflammation. Without these foods people may experience more inflammation, which has been linked with AFib. Another possible explanation is that eating more protein and fat in lieu of carbohydrate-rich foods may lead to oxidative stress, which has also been associated with AFib. Finally, the effect could be related to an increased risk of other forms of cardiovascular disease.

The 15 sanctioned events for the 2019 CrossFit Games are in chronological order:[25] Dubai CrossFit Championship (Dubai), Australian CrossFit Championship (Broadbeach), Wodapalooza (Miami), CrossFit Fittest in Cape Town, CrossFit Strength in Depth (London), Asia CrossFit Championship (Shanghai), Mid-Atlantic CrossFit Challenge (Baltimore), CrossFit Italian Showdown (Milan), Brazil CrossFit Championship (São Paulo), CrossFit Lowlands Throwdown (Apeldoorn), Down Under CrossFit Championship (Wollongong), Reykjavik CrossFit Championship (Reykjavik), Rogue Invitational (Columbus, Ohio), CrossFit French Throwdown (Paris), and the Granite Games (St. Cloud, Minnesota).[19][26][27][28][29] There are 21 sanctioned events announced for the 2020 season.

Self-reports, along with data from certain trials, indicate that very low-carb diets or ketogenic diets might increase symptoms like fatigue, constipation, brain-fog and irritability in some people — side effects that have been nicknamed “the carb flu” or “keto flu.” However, this is usually the case when cutting back carbs dramatically to just about 5 percent to 10 percent of total calories. These side effects usually clear up within 1–2 weeks of changing your diet, after your body adjusts.


A study published in the European Journal of Clinical Nutrition compared the benefits of following a Paleo diet versus a diet recommended by the American Diabetes Association in 24 participants with diabetes. After two weeks, researchers found that the Paleo diet led to greater improvements in blood sugar levels and insulin sensitivity than the conventional diabetes diet. (4)

Low-carb approaches stem primarily from the hypothesis that lowering insulin, a critical hormone that produces an anabolic, fat-storing state, improves cardiometabolic function and induces weight loss.[2] This approach has been recently called the carbohydrate-insulin model.[3]   Studies have shown low-carb approaches to be superior to other dietary approaches in producing rapid weight loss for the first 6-12 months.[4][5][6]  While diets inducing weight-loss produces a caloric deficit, the mechanism of low-carb diets remains in debate.  When lowering carbohydrates from the diet, the macronutrient intake of fat and protein generally increases to compensate for the reduction of carbohydrates.  One hypothesis of why low-carb approaches produce rapid weight loss compared to other diets is that fats and protein increase satiety and produce less concomitant hypoglycemia. This increase in satiety and less rebound hypoglycemia then reduces hunger and overall food intake and produces a caloric deficit.  Additionally, another hypothesis contends that low-carb diets can produce a higher metabolic burn than high-carb diets.  In recent studies, there appears to be a metabolic advantage of approximately 200 to 300 more calories burned compared to an iso-caloric high-carb diet.[2][7]  However, these theories remain controversial.[8]
Low-carb diets may improve high-density lipoprotein (HDL) cholesterol and triglyceride values slightly more than do moderate-carb diets. That may be due not only to how many carbs you eat but also to the quality of your other food choices. Lean protein (fish, poultry, legumes), healthy fats (monounsaturated and polyunsaturated) and unprocessed carbs — such as whole grains, legumes, vegetables, fruits and low-fat dairy products — are generally healthier choices.

By the end of my first Whole30, I had an entire document full of recipes I still wanted to try, which motivated me to keep going. Yes, you can stay compliant by eating steamed chicken and lettuce every day, but why would you do that to yourself? "Find foods that are easy to make and that you enjoy eating," Cohn says. "If you eat foods that you don’t like just to follow the diet, you are not going to continue to eat those foods once you are done with the 30 days." Pro tip: Google the Whole30 version of your favorite meal, there's probably a recipe out there for it. (Unless that meal is cake.) This really helped reignite my love for cooking and encouraged me to continue preparing my own meals, instead of relying on Seamless delivery.
A 2015 study in the Journal of the American College of Cardiology found that 76 people who followed the Paleo diet for 60 days (as well as those who followed vegan, Mediterranean and DASH plans for the same length of time) lost an average of 9 pounds and showed improvement in their blood pressure levels. The effects were greatest and most sustained among people who also attended regular diet support group meetings.
