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. [2] The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
"Soups have a high water content, which means they fill your stomach for very few calories," says Rolls. Broth-based bean soups, in particular, contain a hefty dose of fiber and resistant starch -- a good carb that slows the release of sugar into the bloodstream -- to make that full feeling really stick. "Once in the stomach, fiber and water activate stretch receptors that signal that you aren't hungry anymore," Rolls says. All this for a measly 150 calories per cup.
On 7 September 2010, two cohort studies on L-C diets were published together in the Annals of Internal Medicine (Harvard). The participating subjects were 85,168 women (aged 34 to 59 years at baseline) and 44,548 men (aged 40 to 75 years at baseline) without heart disease, cancer, or diabetes. The women were tracked from 1980 to 2006; the men from 1986 to 2006. The results: Animal-based L-C diets were associated with higher all-cause mortality, while vegetable-based L-C diets were associated with reduced all-cause mortality in general, and cardiovascular mortality in particular.[35] This is an important distinction because ol' Doc Atkins claimed that eating a lot of meat was good for your heart.[36] It should be noted that the fats consumed in an animal-based diet tend to contain a higher percentage of saturated fats than the fats in a vegetable-based diet, which would go a long way toward explaining the differences in cardiovascular mortality risk between such diets.
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 wanted to love this book but it was a bit boring. There was too much detail on the athlete/event testing. "Well, I wanted them to do this, they did it. I liked the result, but I'll probably change it." I understand that the book was supposed to be like a daily journal but it didn't make for great reading. Obviously, putting the games together is a huge undertaking but the day to day pre-games testing of athletes and the results wasn't all that interesting. I did enjoy some of the behind the scenes stuff on the actual games.
More evidence of the heart benefits from a lower-carbohydrate approach comes from a randomized trial known as the Optimal Macronutrient Intake Trial for Heart Health (OmniHeart). (35) A healthy diet that replaced some carbohydrate with protein or fat did a better job of lowering blood pressure and “bad” LDL cholesterol than a healthy, higher-carbohydrate diet.
I often get caught up in focusing on numbers and scales, so I decided not to officially weigh myself before or after Whole30. But I can attest that everything about my body just felt better. I know saying something like "I lost eleven pounds" would sound much more convincing, but I could see that my stomach was slimmer, as was my face (which is awkwardly the first place I gain weight).
If losing body fat is your aim, cutting dietary fat lowers body fat more than restricting carbs, according to a National Institutes of Health study. Kevin Hall, PhD, an NIH senior investigator and lead author, studied 19 men and women who were obese but free of diabetes. Before trying each of two diet types, they ate a diet of 50% of total calories from carbs, 35% from fat, and 15% from protein. Then they reduced total calories by 30% -- while on the low-carb plan they reduced carbs by 60%; while on the low-fat diet they reduced fat by 85%.
Buried in the middle of The Revised Metabolic Oncolytic Regimen for Effecting Lysis in Solid Tumors one can find their diet recommendations for tumor control. It has a paleo diet orientation. Protein is 35%, preferably Omega 3 rich. Carbohydrates (also 35%) are only vegetables and fruit, no beans, bread, potatoes, or any grain. Then dietary and supplemental forms of fat should provide 20-30% of (daily) calories.
Adoption of the Paleolithic diet assumes that modern humans can reproduce the hunter-gatherer diet. Molecular biologist Marion Nestle argues that "knowledge of the relative proportions of animal and plant foods in the diets of early humans is circumstantial, incomplete, and debatable and that there are insufficient data to identify the composition of a genetically determined optimal diet. The evidence related to Paleolithic diets is best interpreted as supporting the idea that diets based largely on plant foods promote health and longevity, at least under conditions of food abundance and physical activity."[35] Ideas about Paleolithic diet and nutrition are at best hypothetical.[36]

This does require effort. Grocery shopping, meal planning, dining out, explaining the program to friends and family, and dealing with stress will all prove challenging at some point during your program. We’ve given you a huge number of tools, advice, and resources, but take responsibility for your own plan. Improved health, fitness, and quality of life doesn’t happen automatically just because you’re now taking a pass on bread.

The concept of the glycemic index was developed in 1981 by David Jenkins to account for variances in speed of digestion of different types of carbohydrates. This concept classifies foods according to the rapidity of their effect on blood sugar levels – with fast-digesting simple carbohydrates causing a sharper increase and slower-digesting complex carbohydrates, such as whole grains, a slower one.[56]


In the long term, you have to be sure you’re getting calcium and other nutrients you’re missing by not having dairy products and certain grains. Some paleo-approved foods, such as salmon and spinach, contain calcium, so you have to be sure you’re including them in your diet. It would be a good idea to check with a registered dietitian, too, to make sure you’re meeting your calcium and other nutrient needs.
