Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health by Gary Taubes expounds on his 2002 article in the NY Times (What if It's All Been a Big Fat Lie?) and then in Science Magazine (see below). He shows how public health data has been misinterpreted to mark dietary fat and cholesterol as the primary causes of coronary heart disease. Deeper examination, he says, shows that heart disease and other diseases of civilization appear to result from increased consumption of refined carbohydrates: sugar, white flour and white rice. Or in other words, without using the word Paleolithic, he justifies the paleo diet. Here is an excellent chapter by chapter summary of the book [archive.org].
While the diet as a whole hasn't been well studied, the benefits of cutting packaged foods from your diet could be huge. According to the Harvard School of Public Health, three quarters of the average American's sodium intake (which is almost double what it should be!) comes from commercially prepared foods. And, one Public Health Nutrition study found that people who cook at least five times a week are 47% more likely to be alive 10 years later compared to those who rely more on processed foods.
A great question to ask is “Does the Paleo diet work?” Here we have a head to head comparison between the Paleo diet and Mediterranean diet in insulin resistant Type 2 Diabetics. The results? The Paleo diet group REVERSED the signs and symptoms of insulin resistant, Type 2 diabetes. The Mediterranean diet showed little if any improvements. It is worth noting that the Mediterranean diet is generally held up by our government as “the diet to emulate” despite better alternatives. You can find an abstract and the complete paper here.
Contrary to popular belief, fat doesn’t make you fat; carbs do (and the Standard American Diet contains a ton of them!). Natural oils and fats are your body’s preferred sources of creating energy, so it’s best to give your body what it’s asking for. The following are some of the best types of paleo diet oils and fats that you can give your body if you’re in need of some additional energy.
There are about half a dozen diets that are very similar. They all recommend you eat "meat and veg" The reason Whole 30 works for me is because you can have potatoes and fruit. An example of a whole 30 meal would be: 2 pork chops, mashed potatoes made with chicken stock, green beans, finish with your choice of fruit. My favorite is a few grapes or pineapple chunks. Also the goal it to make it 30 days without cheating. There have been several times I would think: OK I can't cheat now I only have __ more days to go. Having an end in site helped me. When I started adding back in food groups after the 30 days. I figured out that I do not do well with Dairy. Now the only dairy I use is real butter. I never thought I could live without cheese... But now I don't think it's a good idea for me. So it helps you figure out what you can and can not eat and still feel good.
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?
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. Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods. 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.
Following the paleo diet can be pricey. Inexpensive and healthy non-meat protein sources like soy and beans are off-limits, and a recent BMJ Open study shows that healthy meats like lean ground beef and boneless, skinless chicken breasts cost an average of 29 cents more per serving compared to less-healthy ones, such as high-fat ground beef and chicken drumsticks. Even switching from peanut butter to paleo-approved almond butter will cost you—it goes for up to $13 a jar.
For the wall-ball, the athlete must start with the ball at a dead stop on the ground. The athlete may then pick up the ball and stand tall before beginning a set, or squat clean the ball, before beginning their first repetition of any set. An athlete may not start in a squat, pick up the ball from this position, and toss the ball to the target. A repetition consists of an athlete holding the ball in the “front rack,” and performing a full squat, hip-crease passing below the top of the knee, and when vertically extending throwing the ball to a specific target height. If the athlete’s hip does not break parallel, or the target does not touch the wall, that rep will not be counted. The athlete may then catch the ball and perform multiple reps if they so choose. Finally, athletes may not catch the ball on the bounce, and head right into a wall-ball repetition. The ball must be settled on the floor before picking it up to begin another set.
