The Paleo diet, also referred to as the caveman or Stone-Age diet, includes lean meats, fish, fruits, vegetables, nuts, and seeds. Proponents of the diet emphasize choosing low-glycemic fruits and vegetables. There is debate about several aspects of the Paleo diet: what foods actually existed at the time, the variation in diets depending on region (e.g., tropical vs. Arctic), how modern-day fruits and vegetables bear little resemblance to prehistoric wild versions, and disagreement among Paleo diet enthusiasts on what is included/excluded from the diet. Because of these differences, there is not one “true” Paleo diet.
As of 2016 there are limited data on the metabolic effects on humans eating a paleo diet, but the data are based on clinical trials that have been too small to have a statistical significance sufficient to allow the drawing of generalizations.[not in citation given] These preliminary trials have found that participants eating a paleo nutrition pattern had better measures of cardiovascular and metabolic health than people eating a standard diet, though the evidence is not strong enough to recommend the paleo diet for treatment of metabolic syndrome. As of 2014 there was no evidence the paleo diet is effective in treating inflammatory bowel disease.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
It was in Glassman's own divorce case, though, that the CrossFit defense arsenal launched its full firepower. Lauren and Greg's marriage hit the rocks in 2009. Lauren became pregnant with twins and could no longer travel to the seminars.Greg, wrapped up with CrossFit, became more and more distant. Rumors of infidelity swirled. Soon the two were living in separate houses. In March 2010, Lauren officially filed for divorce. But the case didn't come to a head until July 2012, when Lauren filed a motion to sell her 50 percent stake in the company to Anthos Capital, a Menlo Park, California-based venture capital firm, for $20 million. Glassman, and in short order CrossFit, hit the ceiling.
I can not believe this! Someone recently chewed me out for being unable to afford $25/week for something I need. I’m sorry, but I was born with spina bifida and became permanently disabled at 29, after working since 17! Then, my wonderful caregiver became extremely ill, kept working to afford our lifestyle, but finally his body gave out. Now I’m His caregiver, so our money is overly Tight!
This one was hard for us to grasp, so it deserves some explanation. If a Paleo pancake calls for nothing but Whole30-approved ingredients (eggs and bananas), the flapjack is still off-limits. The Whole30 wants you to change your habits and your emotional relationship with food. "Your brain doesn't know the difference between an almond flour brownie and your mom's recipe; it just knows you crave sugar. So if you keep eating those sweets during the 30 days, your habits aren't changing," Hartwig says. Don't shoot the messenger!
In his gruff way, Glassman recounted his story for the faithful: how a novel, exquisitely punishing system of exercise he had designed, centered on the WOD (workout of the day; it's pronounced "wad"), had started in his backwater Santa Cruz gym, then turned into an online phenomenon, then paved the way for 6,775 CrossFit locations (soon to be 10,000), and now was fast becoming its own sport. (This month, the finals of the CrossFit Games will be broadcast live on ESPN2.) He explained the contrarian way he thinks about the CrossFit business (he shuns most new sources of revenue) and how he goes about protecting its brand (viciously).
Hi Jillian. The natural sugars in fruit really don’t help with my cravings when I’m on a Whole30, so I try to limit them as much as possible. If that’s not a problem for you, you can certainly add more into your daily plan. Personally, my most successful Whole30 was when I went the first 25 days with no fruit whatsoever. Really kicked my sugar cravings to the curb. I was a smoothie girl too.
Origins and Evolution of Human Diet was an academic web site at the University of Arkansas devoted to discussion of evolution and the human diet. They had good articles on the conferences link. Here is one from the archives: Boyd Eaton's Evolution, Diet and Health which argues that current w-6 : w-3 imbalance together with absolute dietary DHA intake quite low in human evolutionary perspective may be relevant to the frequency of unipolar depression.
No background science here or lengthy explanations, only 15 easy guidelines to follow to kick-start your Paleo journey. It’s up to you to decide to what extent you want to follow those guidelines, but if you follow them 100% you can be assured that you are eating the best food for your body and greatly investing in your long term health and well-being.
Cordain admits that meat leads to plaque and increases cholesterol where plants wouldn’t. And science establishes that plaque and cholesterol lead to heart attacks and strokes. But Cordain argues that plaque alone is insufficient to cause harm. Rather, it is plaque combined with inflammation that causes heart attacks and strokes. So avoid acid, salt, legumes, wheat, starchy vegetables, dairy, oil, fatty meats, and grains because they cause inflammation. But if both science and Cordain agree that plaque is a necessary part of the heart-disease equation—and that meat causes plaque—why should we follow Paleo rather than just forgo meat?
In the past few decades, our diets have changed dramatically. Processed foods are more common than fruits and vegetables, and it’s impossible to go more than a few miles down the road without spotting a dozen new fast food chains that have cropped up. Enter the Paleo diet plan, a diet that seeks to ditch the modern convenience foods in favor of the foods eaten by our ancestors.
Like the Paleo Diet, the Keto Diet is low in carbs. But the primary goal of the Keto Diet is to put your body into a state of ketosis, which is when your body uses fat instead of carbohydrates as its primary energy source. When your body enters ketosis, fat travels to the liver and makes an acid called ketones, which enter your bloodstream and are converted into energy.
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.” 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.
CrossFit, Inc. licenses the CrossFit name to gyms for an annual fee and certifies trainers. Besides the standard two-day "Level 1 Trainer Course", specialty seminars include gymnastics, Olympic weightlifting, powerlifting, strongman, running and endurance, rowing, kettlebells, mobility and recovery, CrossFit Kids, CrossFit Football, and self-defense and striking. Other specialized adaptations include programs for pregnant women, seniors, and military special operations candidates. Affiliates develop their own programming, pricing, and instructional methods. Many athletes and trainers see themselves as part of a contrarian, insurgent movement that questions conventional fitness wisdom. In addition to performing prescribed workouts, they follow CrossFit's nutrition recommendations, adopting a paleo and/or zone diet.
