The paleo diet (also nicknamed the caveman diet, primal diet, Stone Age diet, and hunter-gatherer diet) is hugely popular these days, and goes by one simple question: What would a caveman eat? Here, we explain what the paleo diet involves, its pros and cons, and, ultimately, what a modern person needs to know to decide whether or not to take the paleo diet plunge.

Update: So I just finished my first whole30 round and I have to say that I'm super excited by the results. When I hopped on the scale today, I noticed that I had lost 26.6 pounds. I then measured myself and noted that I lost a total of 31.5 inches (-5" from chest, -2" from right arm, -3.5" from left arm, -8" from waist, -5" from hips, -4" from right thigh, and -4" from left thigh). I am really excited by my results!
The Paleo Diet: Eating like your ancestors doesn't guarantee you'll lose weight. While the diet emphasizes plenty of foods that are good for weight loss, such as lean protein and fruits and vegetables, you would still need to eat fewer calories to drop a few pounds. So if you're binging on nuts and fruit, you could actually gain weight on the Paleo Diet.
There is little argument over the health benefits of fruits and vegetables. They are chock-full of vitamins, minerals, fiber and antioxidants. The only caveat for paleo dieters is that some vegetables are starchy (e.g., potatoes) and some fruits are higher in sugar (e.g., bananas). So, if you are trying to lose weight or watch your blood sugar levels, eat these in moderation. In fact, potatoes are banned from some strict versions of the diet.
Plus, I feel like the way I eat directly affects my mood. If I eat sugar, I almost always feel like garbage. If I eat protein and veggies and tons of avocado, I feel stable and much less like I am going to have a stage-four meltdown. Blood sugar swings are also real — no one wants to deal with me when I am hangry. It’s a nightmare. This program is supposed to help with all these things. I desperately wanted to feel better, so I dove in.

After spending a week fine-tuning my new eating plan, I decided to add workouts back into my routine. On a typical week, I'll go to a cardio or strength class (I like boxing) once or twice and do some yoga or stretching at home another night. I dove right in and hit up my favorite boxing studio, Rumble. But I was really nervous. What if I didn't have enough energy? What if I passed out during class? What if I got so hungry I caved and bought a slice of pizza on the walk home from class?
To deal with this major food rut and disinterest in cooking, I bought my lunch every single day from Dig Inn and begged my boyfriend to take me out to dinner at a restaurant with Whole30–compliant options. As someone who typically brings lunch to work and cooks dinner on weeknights, I knew I was spending way over my normal budget, but I couldn't help myself. It was for my sanity.
Before I went on Whole30 I was sleeping 8 to 10 hours a night (yes, I love my sleep), yet come 2 p.m. I'd hit an energy slump. I'd feel high right after I ate (looking back on it, probably because I was eating so much added sugar) but my energy would significantly fluctuate through the day. During the beginning of Whole30 — specifically the first three days — I really struggled. Again, I was a sugar addict and I think detoxing from that really affected my energy levels. But after that slump, my energy was constant — I really had never felt better. Even when things didn't go the way I wanted, I felt energetic and up for any challenge.
Since 2009, Melissa Hartwig’s critically-acclaimed Whole30 program has quietly led hundreds of thousands of people to effortless weight loss and better health—along with stunning improvements in sleep quality, energy levels, mood, and self-esteem. The program accomplishes all of this by specifically targeting people’s habits and emotional relationships with food. The Whole30 is designed to help break unhealthy patterns of behavior, stop stress-related comfort eating, and reduce cravings, particularly for sugar and carbohydrates. Many Whole30 participants have described achieving “food freedom”—in just thirty days.
Trying to devise an ideal diet by studying contemporary hunter-gatherers is difficult because of the great disparities that exist; for example, the animal-derived calorie percentage ranges from 25% for the Gwi people of southern Africa to 99% for the Alaskan Nunamiut.[39] Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods.[39] Modern hunter-gatherers tend to exercise considerably more than modern office workers, protecting them from heart disease and diabetes, though highly processed modern foods also contribute to diabetes when those populations move into cities.[39]

Don’t pour all the curry sauce over the chicken; once the mixture has come into contact with the raw meat, you have to throw it out. Instead, place your chicken in a shallow bowl, and pour a little of the sauce over the chicken. Brush or rub it evenly over the meat, then flip and repeat on the other side. Save the extra sauce to drizzle over the top of this dish before serving, or use it to top tomorrow night’s chicken, shrimp, or vegetables.
In one example, CrossFit, Inc.'s Twitter account posted a doctored illustration of a Coke advertisement, with "Open Happiness" replaced by "Open Diabetes". The image was paired with a quote from CrossFit CEO Greg Glassman that read "Make sure you pour out some for your dead homies."[85][86] Controversy followed after singer Nick Jonas responded to the tweet, calling CrossFit, Inc.'s comments "ignorant".[87] The company defended its tweet, stating that "Compelling statistical evidence supports CrossFit, Inc.'s campaign to prevent diabetes by raising awareness about its causes."[88] When ABC News asked Greg Glassman to comment on the exchange, he replied "Fuck Nick Jonas. This is about the scourge of Type 2 Diabetes and its underlying causes. His sponsor, Coca-Cola, is a significant contributor to the diabetes epidemic both with product and 'marketing' spend."[1][88]
For the handstand push-up, prior to the start of the workout, athletes must measure out and mark a box measuring 36in wide by 24in from the floor. This is for the athlete’s hand placement. The athlete’s palms may not extend beyond this box over the course of any handstand push-up repetition, however, their fingers may. The box must be marked out clearly to be visible in the video. Each repetition begins with the kicking upside down, onto the wall, with the athlete’s hands clearly inside of the box, arms and shoulders locked out, body vertically aligned, with feet in contact with the wall. Once this position is established, the athlete may lower their body down to bring their head in contact with the ground. From here, the athlete may use any style of handstand push-up, including kipping or strict, to press and finish with their body vertically aligned, arms and shoulders locked out, and feet in contact with the wall. Each rep must have the athlete’s head make contact with the floor, and finish in this extended position. If at any point in time an athlete kicks off the wall, they must first establish the locked out finish position, with body vertically aligned before lowering down to begin repetitions. If over the course of a repetition, the athlete’s hands leave the marked box, that rep shall not count. However, if the athlete is resting with their head on the floor, they may adjust their hands (which may have them come out of the box,) but must return them to the box before attempting to complete another repetition. If head cushioning is used, please ensure the head is still level with the hands, or your score will not count
Evolution of the Human Diet: The Known, the Unknown, and the Unknowable by Peter S. Ungar. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. The book has four sections: Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics. Archaeological evidence of subsistence--stone tools and modified bones. Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics. Nutritional analyses and their implications for evolutionary medicine.
For example, although white potatoes were recorded as being available during the Paleolithic era, they are usually avoided on the Paleo diet because of their high glycemic index. Processed foods are also technically off limits due to an emphasis on fresh foods, but some Paleo diets allow frozen fruits and vegetables because the freezing process preserves most nutrients.
Autoimmunity is a process in which our bodies own immune system attacks “us.” Normally the immune system protects us from bacterial, viral, and parasitic infections. The immune system identifies a foreign invader, attacks it, and ideally clears the infection. A good analogy for autoimmunity is the case of tissue rejection after organ donation. If someone requires a new heart, lung kidney or liver due to disease or injury, a donor organ may be an option. The first step in this process is trying to find a tissue “match”. All of us have molecules in our tissues that our immune system uses to recognize self from non-self. If a donated organ is not close enough to the recipient in tissue type the immune system will attack and destroy the organ. In autoimmunity, a similar process occurs in that an individuals own tissue is confused as something foreign and the immune system attacks this “mislabeled” tissue. Common forms of autoimmunity include Multiple Sclerosis, Rheumatoid Arthritis, Lupus, and Vitiligo to name only a tiny fraction of autoimmune diseases. Elements of autoimmunity are likely at play in conditions as seemingly unrelated as Schizophrenia, infertility, and various forms of cancer.
For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].

Bob is right on. The only announcement which was even worth watching was the last one because they brought back tommy Marquez and Co. the open this year was an absolute joke. I watched the first one, w high anticipation, laughed my butt off in embarrassment and didn’t watch again until 5 when I heard Marquez was back. Also, good luck w the top athletes from countries with like 10 actual crossfitters. What’s the point of bringing in an athlete who will be ousted in the first 5 min of the games while Brent Filowski sits home? Good call
I thought Week 1 was hell on earth, but boy was I wrong. Week 4 tested my patience and willpower like never before. Eating Whole30 staples like avocado and eggs became a chore. I choked down so many hard-boiled eggs during my last week, but all I could think about was how I wished they were freshly baked bagels—or even just a bowl of plain white rice. Anything but eggs.

Trying to introduce dairy back into my diet hurt my stomach and would send me into a sneezing fit. In this way, the Whole30 worked as a type of elimination diet for me, without which I may have never realized that dairy isn't my friend. I'll still suffer the consequences if I cross paths with a cheese plate at a work event, but I've made the permanent switch to tofu cream cheese and coconut milk — alternatives I would've never touched before Whole30 that are actually delicious.
In response to these criticisms, CrossFit, Inc. claims, “CrossFit is relatively safe even when performed with poor technique, but it is safer and more effective when performed with good technique.”[58] CrossFit, Inc. also claims risk for injury can be reduced by properly scaling and modifying workouts, a concept taught on its website and at the CrossFit Level 1 Trainer Course.[59][60]
