When it comes to losing weight, calorie counting is crazy, but shifting your attention to the types of foods you eat and focusing on mindful eating can make all the difference. Low-carb diets have a reputation for producing fast weight loss without feeling hungry or needing to count calories. In fact, many people experience weight loss following a low-carb diet even if they’ve tried “everything else” and never got the results they were looking for.
When it comes to humans, we’re all just victims of our own biochemistry. Our brains are controlled and ruled by chemicals - from what we eat; to how and when we sleep; even to who we choose as a life partner. Biochemistry - or ‘biological chemistry’ - is concerned with all of the biochemical reactions which take place within our bodies and brains. This means that the simple act of eating a meal is actually composed of thousands of tiny...
The plan focuses on unprocessed foods and foods with very minimal, or, better yet, no added ingredients. Whole30 requires dieters to cut out a lot of items, including sugar, dairy and legumes, and then slowly reintroduce these food groups back into their diets after the 30 days. The purpose of the reintroduction phase is to see if any of the foods cut out are the culprit for any health issues.
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.
LOREN CORDAIN, Ph.D., is one of the top global researchers in the area of evolutionary medicine. Generally acknowledged as the world's leading expert on the Paleolithic diet, he is a professor in the Health and Exercise Science Department at Colorado State University. Dr. Cordain and his research have been featured on Dateline NBC and in the New York Times, the Wall Street Journal, and other media. He is the author of The Paleo Diet and The Paleo Diet Cookbook, among other books, and makes regular media and speaking appearances worldwide.

Hi there Libby, just to let you and your readers know, I have been low carb for over a year now, ( sometimes I fall down and have processed carbs, mostly when I am travelling away from home) and the good news is I was diabetic, and now I am pre-diabetic, which is huge :O) I have also lost a small amount of weight in the process ( still more to go :O) but this eating plan makes me feel normal again, not always hungry, and I am a lot healthier than I was :O) now all I need to do is make exercise a habit :O) So thank you so much for all the time and energy you put in to this site, and all of these wonderful recipes :O)

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.


The CrossFit Games are the world’s premier test to find the Fittest on Earth™. They are world-renowned as a grueling test for the toughest athletes on Earth as well as a thrilling experience for spectators. Since its inception in 2007, the CrossFit Games have become “one of the fastest growing sports in America,” according to Forbes. Learn more about CrossFit >
As low-carb dietitian Franziska Spritzler, RD, CDE, who’s based in Orange County, California, points out, when you cut back on carbs, blood sugar and insulin levels generally go down, which can be a good thing for some people. “Carbs are broken down into glucose, which raises your blood sugar and prompts your pancreas to produce insulin to drive sugar into your cells,” says Spritzler. “When you’re overweight or obese, your blood sugar goes up and your pancreas sends out insulin, but your cells may not be responsive, leading your pancreas to overproduce insulin,” she says. High insulin increases hunger and prompts fat storage, she explains.
"Loren Cordain's extensive research demonstrates how modern westernized diets drastically depart from the original diet humans consumed for millions of years. In The Paleo Diet and The Paleo Diet Cookbook, Dr. Cordain shows how diets high in grains, dairy, vegetable oils, salt, and refined sugars are at odds with our genetic legacy and then shares his uncomplicated strategy for losing weight and getting healthy."

Remove the chicken from the curry sauce and discard the extra sauce. Add the chicken, breast-side down, to the grill and sear until golden brown, about 2 minutes. (When the meat is properly seared it will pull off the grates very easily, so don’t rush this step.) Turn the chicken over so the bone side is down and place over indirect heat. Cover with the grill lid and continue to cook until the internal temperature of the chicken is 160°F, or the breast meat springs back when pressed with a finger. This will take 10 to 15 minutes, depending on thickness.
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.
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.
Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.

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]
Research shows that a diet high in refined carbohydrates and sugar contributes to free radical damage and actually feeds cancer cells, possibly helping them proliferate faster. Because low-carb diets dramatically cut down sugar and lower intake of grains and processed foods, they might act like a natural cancer treatment, causing immunity to improve as oxidative stress goes down.
You mentioned ketone strips. If they are the urine strips they are useful to see if you are in ketosis, fat burning mode, but be aware they are not completely accurate but are a good guide to how you are doing. The blood strips are way too expensive but more accurate. I have a blood glucose monitor and went through a phase of testing to see how I react to dairy, protein, cream, coffee etc. I rarely do it now as I want this way of eating to be as simple as possible, but again, a useful tool starting out.
The New Evolution Diet: What Our Paleolithic Ancestors Can Teach Us about Weight Loss, Fitness, and Aging by Arthur De Vany. Art is the grandfather of the "Paleo Lifestyle" movement. The plan is built on three principles: (1) eat three meals a day made up of nonstarchy vegetables, fruits, and lean proteins; (2) skip meals occasionally to promote a low fasting blood insulin level; and (3) exercise less, not more, in shorter, high-intensity bursts. Note that the book is anti-fat. All oils are to be avoided, though canola is considered okay for higher temperatures. Egg yolks are to be skipped now and then. Published December 21, 2010.

The best way to start eating a lower-carb diet is to simply focus on eliminating major sources of added sugar and carbohydrates — especially from sugar snacks, sweetened drinks, grains and possibly legumes and dairy, too. At the same time, work on increasing calories from healthy fats and quality proteins. By following these guidelines, most adults will see fast weight loss and improvements in overall health.


Carbohydrate has been wrongly accused of being a uniquely "fattening" macronutrient, misleading many dieters into compromising the nutritiousness of their diet by eliminating carbohydrate-rich food.[26] Low-carbohydrate diet proponents emphasize research saying that low-carbohydrate diets can initially cause slightly greater weight loss than a balanced diet, but any such advantage does not persist.[26][6] In the long-term successful weight maintenance is determined by calorie intake, and not by macronutrient ratios.[7][6]
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?
But eventually — probably on day 33 — I started to experiment. First came eating ketchup ... no side effect. Next, I had some red wine ... a slight hangover the next day, but nothing like I used to experience when indulging in sugary cocktails. Then, I added gluten ... and my body officially freaked out. I broke out in a rash and hives all over my scalp, neck, and legs which lasted for a few days. I decided to try eating gluten again after the rashes went away to make sure, and sure enough, I woke up the next day to ... more rashes.
Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrat by Mary G. Enig, Ph.D. and Sally Fallon. The premise is the culinary traditions of our ancestors, and the food choices and preparation techniques of healthy nonindustrialized peoples, should serve as the model for contemporary eating habits. However, they push whole grains and dairy, which aren't Paleolithic.

The simple fact is that many of us eat more carbohydrates than our bodies can handle. We can see this with people with diabetes who eat too much of a certain food and lose control of their blood sugar. The aim of a low-carb diet, therefore, is to reduce the consumption of carbohydrates to keep our GI in check, while maintaining good nutrition and achieving sustainable weight loss.


The CrossFit Games is an athletic competition sponsored by Crossfit Inc.[1] and Reebok.[2] The competition has been held every summer since 2007. Athletes at the Games compete in workouts that they learn about hours or days beforehand, consisting mostly of an assortment of standard aerobic, weightlifting, and gymnastics movements, as well as some additional surprise elements that are not part of the typical CrossFit regimen such as obstacle courses, ocean swimming, softball throwing, or ascending a pegboard.[3][4] The CrossFit Games stylizes their individual winners as the "Fittest on Earth".[5]

I started seeing a nutritionist, who has started me on a B-12 injection 2 times monthly, and a LCHF diet. He wants me to stay between 20-35 carbs daily for at least 3 months. He says I need to buy ketone strips, to make sure I don’t go into ketoacidosis, however, I am otherwise healthy, and not diabetic. Is this something I need to be overly concerned about? I’m on my 4th day of approx. 25 carbs daily, and other than a slight headache, I feel fine.
Chris Masterjohn has Cholesterol: Your Life Depends on It!, another web site pointing out that the war on cholesterol and the push to put people on statins is misguided. The site argues it is actually polyunsaturated fats, not saturated fats or cholesterol, that contribute to heart disease, cancer, liver damage, and aging. He also has a popular blog.

Paleo diets are based on a simple premise – if the cavemen didn’t eat it, you shouldn’t either. So long to refined sugar, dairy, legumes and grains (this is pre-agricultural revolution), and hello to meat, fish, poultry, fruits and veggies. The idea is that by eliminating modern-era foods like highly-processed carbs and dairy, you can avoid or control “diseases of civilization” like Type 2 diabetes and heart disease, and likely lose weight too. What you eat and how much depend on your goals or the specific program you’re on, if you choose to follow one. The high-protein diet is ranked poorly among U.S. News experts, who consider it too restrictive to be healthy or sustainable.
