Although there has been some research done throughout the twentieth century, most directly relevant scientific studies have occurred in the 1990s and early 2000s and, as such, are relatively new and the results are still debated in the medical community.[35] Supporters and opponents of low-carbohydrate diets frequently cite many articles (sometimes the same articles) as supporting their positions.[36][37][38] One of the fundamental criticisms of those who advocate the low-carbohydrate diets has been the lack of long-term studies evaluating their health risks.[39][40] This has begun to change as longer term studies are emerging.[41] A meta-analysis of five clinical trials including 447 individuals found that low fat and low carbohydrate diets are equally effective for weight loss up to one year. [42]
For most people the fact the Paleo diet delivers the best results is all they need. Improved blood lipids, weight loss, and reduced pain from autoimmunity is proof enough.  Many people however are not satisfied with blindly following any recommendations, be they nutrition or exercise related. Some folks like to know WHY they are doing something. Fortunately, the Paleo diet has stood not only the test of time, but also the rigors of scientific scrutiny.
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.

The Raw Paleo Diet & Lifestyle site is a resource created by members of the Raw Paleolithic Diet community for people looking to improve their health by choosing a more historically natural approach to diet, fitness and lifestyle. They have two forums: Raw Paleo Forum. It has some activity. And Raw Paleo Diet, or RVAF Raw Veg and Animal Foods Group, a forum for followers of semi-RPD diets, (such as Aajonus Vonderplanitz's Primal Diet/Weston-Price Diet/Sally Fallon/Instincto) and followers of the NeanderThin/Paleo/Stefansson Diets, who, for health reasons, wish to pursue a more fully Raw, Paleolithic variation of those diets.

2. Simple carbohydrates (high glycemic load foods, or foods that are not part of a type 2 diabetes diet plan because they raise blood sugar levels) are processed foods, and don't contain other nutrients to slow down sugar absorption and thus these foods can raise blood sugar dangerously fast. Many simple carbohydrates are easily recognized as "white foods."


Best of all, you will see amazing results in a short amount of time. Your hips, thighs, and stomach will be thinner, the number on the scales will go down, and all those overwhelming food cravings will be gone! Just imagine losing weight while still enjoying many of your favorite foods. With the diet, you can dine on mouth-watering foods like Chicken en Papillote, Shrimp Louis, and even Chocolate Sponge Cake and still lose the weight!


A diet high in phytic acid, which can be found in whole grains (it's in the bran) and beans like soy, is very detrimental for mineral absorption. Phytic acid strongly binds to minerals like calcium, iron, zinc and magnesium to form insoluble salts, phytates, which precipitate from the body and are not absorbed. Staffan Lindeberg has written a summary on phytic acid.
The researchers tracked biomarkers that helped them ensure that the participants stuck to their diets. They also worked with a large food service company, Sodexo, to prepare thousands of generally healthful meals that the subjects could eat in cafeterias or take home with them. A typical meal for the high-carb group might consist of a chicken burrito bowl with rice and vegetables, for example, or roasted turkey with green beans and mashed potatoes. The low-carb group would get a similar meal with fewer carbohydrates, like a chicken burrito lettuce wrap or roasted turkey with green beans and mashed cauliflower.
The Lazy Paleo Enthusiast's Cookbook: A Collection of Practical Recipes and Advice on How to Eat Healthy, Tasty Food While Spending as Little Time in the Kitchen as Possible by Sean Robertson. The author is a recovering vegan and in the first half of the book recounts his dietary experiences using some paleo foods to restore his health. You learn that the author's main strategy is to make food in large batches which can be reheated to provide dinners for several days running. The second half of the book contains 28 recipes. Some borderline or nonpaleo ingredients do appear, but most of the recipes are more paleo than not. Published November 15, 2011.

The diet food that Southbeach diet sends is horrible! I even had my husband taste it to make sure it was not just me. It is has very little taste. The breakfast meals are the worst. I tried their bacon, onion and pepper egg scramble and I couldn’t even force it down. It was absolutely horrible!!! I have had Jenni Craig food and at least I like their food. Southbeach frozen and shelf food, not so much. What a waste of money! I found out today that even if you are not satisfied with their product they will not refund you nor will they accept returns. I can’t see how this company will even make it when their food tastes so bad. I spent over $300 for food I can’t even force myself to eat. VERY BAD FOOD! What a waste of money!!!
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.

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.
Fat isn’t unlimited either. As with wine, it's possible to get too much of a good thing when it comes to healthy fats. The American Heart Association points out that while the Mediterranean diet meets heart-healthy diet limits for saturated fat, your total fat consumption could be greater than the daily recommended amount if you aren't careful. That’s 65 g per day. (32)
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.[6] 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.[7] 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%.[3]
Paul Burke's Neo-Dieter's Handbook: When We Lost Our Nutritional Roots; Where to Find These Foods Today by Paul Burke M. Ed. The book focuses on nutrition, the right nutrition to enhance health, exercise, weight training, and fitness. The diet consists of lean protein, vegetables, nuts, and fruit. He is opposed to grains. He wants you to stay away from grain-fed meat. The single review at Amazon.com gives the book 5 stars. Published August 21, 2009.

As of 2015 the AHA stated categorically that it doesn't recommend high-protein diets. It states: "The American Heart Association doesn't recommend high-protein diets for weight loss. Some of these diets restrict healthful foods that provide essential nutrients and don't provide the variety of foods needed to adequately meet nutritional needs. People who stay on these diets very long may not get enough vitamins and minerals and face other potential health risks."[31] A science advisory from the association further states the association's position that these diets may be associated with increased risk for coronary heart disease.[32] Robert H. Eckel, past president, noted that a low-carbohydrate diet could potentially meet AHA guidelines if it conformed to the AHA guidelines for low fat content.[33]


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.
Some studies of low carbohydrate diet permit up to 40% of dietary calories as carbohydrate, which leads to null bias, as this level of mild carbohydrate restriction is inadequate to produce the metabolic changes seen with more significant restriction of carbohydrate intake. Compared with those on a low fat diet, persons who restrict dietary carbohydrate intake to less than 26% of total dietary calorie intake have a greater reduction in body weight but a greater increase in HDL-cholesterol and also a greater increase in LDL-cholesterol.[24]

Phase 1. This two-week phase is designed to eliminate cravings for foods high in sugar and refined starches to jump-start weight loss. You cut out almost all carbohydrates from your diet, including pasta, rice, bread and fruit. You can't drink fruit juice or any alcohol. You focus on eating lean protein, such as seafood, skinless poultry, lean beef and soy products. You can also eat high-fiber vegetables, low-fat dairy and foods with healthy, unsaturated fats, including avocados, nuts and seeds.
Hi I’m only new to LCHF and you’re information has been amazing, thank you! I have one question though I’m doing well cutting out sugar, breads etc but just wondering do I need to portion control my meals? Typically I have a 2 egg one letter with cheese, spinach and mushrooms for breakfast. Then warm chicken salad with rocket, cucumber, tomatoes, Persia fetta and a poaxhed egg. Dinner yellow curry with brocoli, carrot on cauliflower rice. Snack a low carb cheesecake, nuts maybe a smoothie.
Like other fad diets, the Paleo diet is promoted as a way of improving health.[2] There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet[6] or compared with diets recommended by national nutritional guidelines.[9] There is no good evidence, however, that the diet helps with weight loss, other than through the normal mechanisms of calorie restriction.[10] Following the Paleo diet can lead to an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches.[3][10]
There are 3 phases to the South Beach Diet. "The South Beach Diet provides the right nutrients to keep you feeling satisfied, while still losing weight. Phase 1 is about breaking the sugar habit. In phase 2, good carbs like fruits and whole grains are added and then phase 3 is really about how you’ll eat to maintain a healthy weight," says Dr. Agatston.

The South Beach diet consists of three phases. For the first two weeks, you are not allowed to eat bread, potatoes, rice, pasta, baked goods, fruit, sugar or consume alcohol. At the next level carbohydrates are added slowly, but it is still important that weight loss continues. In the third phase, when the goal regarding body weight has been reached, carbohydrates are added at the individuals choice.
A 20-year prospective study of 82,802 women looked at the relationship between lower carbohydrate diets and heart disease; a subsequent study looked at lower carbohydrate diets and risk of diabetes. Women who ate low-carbohydrate diets that were high in vegetable sources of fat or protein had a 30 percent lower risk of heart disease (4) and about a 20 percent lower risk of type 2 diabetes, (34) compared to women who ate high-carbohydrate, low-fat diets. But women who ate low-carbohydrate diets that were high in animal fats or proteins did not see any such benefits. (4,34)
Firstly take a look at the cholesterol myth page, that will explain how it is the carbohydrates in your diet which makes you at a higher risk of heart disease than your fat intake, and secondly meat is one of the most nutritious foods you can have. Sure if you want to give up meat for ethics and personal reasons, but not for your health. Take a look at Zoe Harcombes fabulous post on that subject. By lowering your carbs (and processed foods) you will lower your blood pressure and improve you cholesterol profile. It’s not about how much cholesterol you have, but what type.
Some randomized controlled trials have shown the Paleo diet to produce greater short-term benefits than diets based on national nutrition guidelines, including greater weight loss, reduced waist circumference, decreased blood pressure, increased insulin sensitivity, and improved cholesterol. However these studies were of short duration (6 months or less) with a small number of participants (less than 40). [4-6]
Almost everything in this diet is good for your heart. Olive oil and nuts help lower "bad" cholesterol. Fruits, veggies, and beans help keep arteries clear. Fish helps lower triglycerides and blood pressure. Even a daily glass of wine may be good for your heart! If you've never fallen in love with fish, try this Mediterranean-inspired recipe for Grilled Whole Trout With Lemon-Tarragon Bean Salad.
Meet Grok. According to his online profile, he is a tall, lean, ripped and agile 30-year-old. By every measure, Grok is in superb health: low blood pressure; no inflammation; ideal levels of insulin, glucose, cholesterol and triglycerides. He and his family eat really healthy, too. They gather wild seeds, grasses, and nuts; seasonal vegetables; roots and berries. They hunt and fish their own meat. Between foraging, building sturdy shelters from natural materials, collecting firewood and fending off dangerous predators far larger than himself, Grok's life is strenuous, perilous and physically demanding. Yet, somehow, he is a stress-free dude who always manages to get enough sleep and finds the time to enjoy moments of tranquility beside gurgling creeks. He is perfectly suited to his environment in every way. He is totally Zen.

Yet it’s an incredibly well-rounded way to lose weight that ditches gimmicks and doesn’t require calorie or macronutrient counting as other diets do. And with the emphasis on healthy fat, it’s satisfying, too. That said, while the 2018 U.S. News & World Report Best Diets ranked the Mediterranean diet as being tied for first with the DASH diet overall, it ranks 14 in their list of Best Weight-Loss Diets. (3) The reviewers note that it’s not a slam dunk, and all depends on how you eat. Even healthy diets like the Mediterranean aren’t free-for-all eating plans.
If you have diabetes, you should focus on eating lean protein, high-fiber, less processed carbs, fruits, and vegetables, low-fat dairy, and healthy vegetable-based fats such as avocado, nuts, canola oil, or olive oil. You should also manage your carbohydrate intake. Have your doctor or dietitian provide you with a target carb number for meals and snacks. Generally, women should aim for about 45 grams of carb per meal while men should aim for 60. Ideally, these would come from complex carbs, fruits, and vegetables.
I tried Nutrisystem myself and I got so bored because everything tasted the same. It was to the point where I would start being mean to my poor sweet boss because I was so annoyed with lack of variety. On South Beach, do I have to buy the meal plan? I actually really enjoy cooking and I don’t want to have to live on pre packaged foods, which is another reason I really hated Nutrisystem. Can I prepare the food fresh for myself on South Beach?

Both the keto diet and the paleo diet are all the rage right now, with many people choosing one or the other in an effort to change their eating habits, get healthier, and be better able to enjoy their lives. For many people, however, it can be difficult or even confusing to understand the differences between the two and how to manipulate their eating habits in order to achieve their goals. If you're thinking about a drastic lifestyle change,...


One review, published in April 2016 in The American Journal of Medicine, looked at five research trials on overweight and obese people and found that after one year those who followed a Mediterranean diet lost as much as 11 pounds (lbs) more than low-fat eaters. (6) (They lost between 9 and 22 lbs total and kept it off for a year.) But that same study found similar weight loss in other diets, like low-carb diets and the American Diabetes Association diet. The results suggest, the researchers say, that “there is no ideal diet for achieving sustained weight loss in overweight or obese individuals.”

Hi Libby. Re foods to eat. Still a newbie and exploring all this. Re the foods for example cocnut cream- is there a specific brand or type you,should buy? Same with butter and meats- re grass fed versus grain fed. Coconut oil- is there ones you should or shouldn’t use brand wise. Lchf site says grass fed meat and butter. Does it have to say organic on the butter. Labelling is really bad in regards to this. And your cheeses- re Brie for,example- are they all they same or are there certain ones of them you have to buy ? This goes for all cheese that you can have to- are there ones better for you than others?


The Mediterranean diet is most famous for its benefit to heart health, decreasing the risk of heart disease by, in part, lowering levels of “bad” LDL cholesterol, and reducing mortality from cardiovascular conditions. It’s also been credited with a lower likelihood of certain cancers, like breast cancer, as well as conditions like Parkinson’s disease and Alzheimer’s disease. (1)
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.”
It’s not as hard to make healthy choices when you don’t have to explain them over and over. I would recommend that anyone doing phase one start it during a lag in their social schedule. Alcohol is a no-no on South Beach, so once you no longer feel like you have to have all the drinks—and it becomes easier to say no to fried and battered appetizers—that’s when you can venture back out.
Still, many scientists have expressed concern that we do not yet have enough evidence to make any strong claims about the paleo diet’s health benefits, especially its long-term effects. In fact, in an article in response to the first review, authors Tanis R. Fenton and Carol J. Fenton, from the Cumming School of Medicine in Canada, wrote a letter to the editor in which they expressed their disappointment with the review.

Meetup has a growing number of paleo groups, now numbering in the dozens. Each has a local message board. They have a map of Paleo Diet Meetups around the world. Initially I tried listing them all here. The number grew and Meetup wasn't letting me find groups in newest order, except for my zip code. You now have to go there to find the one nearest you.


South Beach Diet is OK. There are a lot of complaints on this page,and here’s what I’ll say. People don’t like the small portions and frozen food, but it was my bad decisions with food (and big portions) that made me have to go on a diet like South Beach to begin with. If you are going to try meal delivery diet, try Nutrisystem instead. It’s cheaper, a little better, and even made by the same company as South Beach Diet!
Benefits The main ingredient in hummus, chickpeas pack an impressive amount of fiber (more than half of a woman’s 25 g daily quota), as well as iron, zinc, folate, and magnesium, according to a paper published in November 2014 in the journal Applied Physiology, Nutrition, and Metabolism. (15,16) The stats above are for a whole cup, but you only need ½ cup per day to reap the benefits.

Fact: The food is a huge part of the diet, yes, but don't overlook the other ways the Mediterraneans live their lives. When they sit down for a meal, they don't sit in front of a television or eat in a rush; they sit down for a relaxed, leisurely meal with others, which may be just as important for your health as what's on your plate. Mediterraneans also enjoy plenty of physical activity.
July 2016 I weighed 225 lbs. and was desperate for a way of eating that I could lose weight with but not starve doing so. This book contained the answers I'd been seeking for years and, in my opinion, is the perfect starter book to understanding the Paleo eating plan. By July 2017 I dropped 65 lbs., felt absolutely great, and became a strong proponent of eating this way for a lifetime. Loren Cordain keeps it simple and straight-forward, explaining the diet in an uncomplicated manner.
Grass-fed meat is recommended on the paleo diet because it is leaner than meat from grain-fed animals and has more omega-3 fatty acids, the healthy fats that reduce inflammation in the body and protect your heart. A typical American diet is high in saturated and trans fats and lower in healthy poly- and monounsaturated fats, hence the paleo diet's emphasis on grass-fed meats, as well as seafood.

In one meta analysis done in 2017, the authors agreed on the possibility of a vegetarian diet having preventative effects on Type 2 Diabetes development; however, they concluded that more research on this field needs to be conducted.[35] Another meta analysis that included twelve cohort studies concluded that red meat consumption is associated with an increased risk of Type 2 Diabetes.[36]  A third meta analysis done in 2013 that compared a variety of different diets' effects on health concluded that a plant based diet high in whole foods, and with limited processed foods can be beneficial for the treatment and prevention of Type 2 Diabetes.[37]

Get rid of the temptation – if you’re gonna go at this thing with a full head of steam, remove all the junk food from your house.  It’s going to take a few weeks for your body to adjust to burning fat instead of glucose, and you might want to eat poorly here and there. If there’s no food in your house to tempt you, it will be much easier to stay on target.
I know you posted a few months ago, but I thought I would reply just incase its still relevant. After having a daughter who LOVES veges, I then had my son who at a year old suddenly refused veges. It was getting so bad he would make himself throw it up if we forced him. But we kept on going trying everything we could while getting extremely frustrated (While also being told by everyone he was too small and sickly (Which he always was but got worse when he stopped eating the veges)
The Primal Blueprint Cookbook: Primal, Low Carb, Paleo, Grain-Free, Dairy-Free and Gluten-Free by Mark Sisson and Jennifer Meier. Recipes include: Roasted Leg of Lamb with Herbs and Garlic, Salmon Chowder with Coconut Milk, Tomatoes Stuffed with Ground Bison and Eggs, and Baked Chocolate Custard. Recipes are simple and have limited ingredients. Complaints are the book is stuffed with unnecessary photos and proofreading could have been better, e.g. oven temperatures were left out. And recipes are not truly paleo. Despite what is on the cover dairy is used in some recipes. The Amazon reviews average to 4+ stars.
I don’t understand all of the chocolate and nuts that you eat in South Beach Phase One. I have eaten more chocolate (or drank in shakes) than ever, as I rarely eat chocolate… I gained 2 lbs in the first 4 days. I stuck to their chocolate and nut diet with a little bit of meat and sauce, and some raw vegetables, and I gained weight! I broke down and cried.

The final benefit we’ll discuss is a balanced dietary alkaline load. While this concept sounds complex, it’s actually quite simple: after digestion, all foods present either a net acid or alkaline load to the kidneys. Meats, fish, grains, legumes, cheese, and salt all produce acids, while Paleo-approved fruits and vegetables yield alkalines. A lifetime of excessive dietary acid may promote bone and muscle loss, high blood pressure, an increased risk for kidney stones, and may aggravate asthma and exercise-induced asthma. The Paleo diet seeks to reduce the risk of chronic disease by emphasising a balanced alkaline load.
In most diet studies, where people aren’t fed every calorie by researchers, the low-carb diet performs about the same as other diets when it comes to weight loss. In other words, when you just ask people to stick to a low-carb diet for weight loss, they lose about the same amount of weight as people following higher-carb diets. This isn’t a knock on the study, but on the fact that researchers don’t yet know how to get people to follow any diet over the long term, unless they’re feeding them.

Oh, by the way : We are prematurely killing our beloved pets with carbs. Dogs and especially cats need to eat meat, but commercial pet food is mostly corn & wheat, which was bad enough before being poisoned by weed killer (“Round-Up” which is soaked into all American grain today) …. Huge numbers of cats and dogs now suffer & die from kidney failure, and the only explanation is what we are feeding them. My kitties now get chicken and tuna, which is a lot cheaper than any ‘gourmet’ canned food. Cooking for them is kinda fun, for that matter.


Because physical activity lowers your blood glucose, you should protect yourself against low blood glucose levels, also called hypoglycemia. You are most likely to have hypoglycemia if you take insulin or certain other diabetes medicines, such as a sulfonylurea. Hypoglycemia also can occur after a long intense workout or if you have skipped a meal before being active. Hypoglycemia can happen during or up to 24 hours after physical activity.
