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 [].
He developed wacky routines: He had clients race their way through repetitions on a weight machine, and at one facility, he had them scramble up a 30-foot column in the middle of the room. Eventually, the owner of that gym welded disks to the pole to make him stop. "They added a hazard 15 feet up," Glassman cracked to clients, before signaling them to go up anyway. He got kicked out of that gym. He got kicked out of several gyms. "I've never wanted to be told what to do," Glassman says. "I think it's genetic."

Evolutionary biologist Marlene Zuk writes that the idea that our genetic makeup today matches that of our ancestors is misconceived, and that in debate Cordain was "taken aback" when told that 10,000 years was "plenty of time" for an evolutionary change in human digestive abilities to have taken place.[4]:114 On this basis Zuk dismisses Cordain's claim that the paleo diet is "the one and only diet that fits our genetic makeup".[4]

You likely will lose weight on Whole30—“many people do appear to lose weight while following the plan, likely due to the decreased reliance on processed foods and increased consumption of whole foods, such as fruits and vegetables,” says Cohen. But it wasn’t designed for weight loss, and once the 30 days are over, you may gain all the weight back as you reintroduce your body to a normal diet.

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.
Meetup has a growing number of paleo groups, now numbering in the dozens. Each has a local message board. They have a map of Paleo Diet Meetups around the world. Initially I tried listing them all here. The number grew and Meetup wasn't letting me find groups in newest order, except for my zip code. You now have to go there to find the one nearest you.

A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
