You may lose weight on the Paleo Diet. If you build a “calorie deficit” into your Paleo plan – eating fewer calories than your daily recommended max or burning off extra by exercising – you should shed some pounds. How quickly and whether you keep them off is up to you. A 2015 review in the Journal of Gastrointestinal Liver Diseases concluded that a Paleo-esque diet “might be an acceptable antidote to the unhealthy Western diet, but only unequivocal results from randomized controlled trials or meta-analyses will support this hypothesis.” On that, we’re still waiting. In the meantime, here’s what has been found about the diet and others like it:
Our ancestors didn't chase cows and chickens around in the wild. They hunted game, antelopes, buffalo, and probably some animals we've never heard of that are long extinct. Their meat was generally quite lean, and provided more healthy omega 3s than meats from modern day animals, even the grass-fed ones, according to Dr. Katz. Many of the plants that thrived back then are also extinct today, making it impossible to truly follow their meal plan, he says.
Food and Western Disease: Health and nutrition from an evolutionary perspective by Staffan Lindeberg (MD at Lund University in Sweden) is the newest book promoting the paleo diet. It covers the link between diet and disease in the Western world (all major diseases, including cancer, heart disease, obesity, stroke and dementia) and towards a greater knowledge of what can be defined as the optimal human diet. Benefits and risks are detailed. The Amazon reviews are all 5 stars. Especially read Susan Schenck's detailed review. You can read a preview at Google Books
Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.
People looking for support and community – This is the appeal to CrossFit for me: every CrossFit gym has a really tight-knit community feel to it. You’re not just a membership payment to them; you’re a person that needs support. When Nerd Fitness gyms start popping up (don’t think it won’t happen!), I’ll be drawing a lot of inspiration from CF as to how members are so supportive and inclusive of each other.
Chris Masterjohn has Cholesterol: Your Life Depends on It!, another web site pointing out that the war on cholesterol and the push to put people on statins is misguided. The site argues it is actually polyunsaturated fats, not saturated fats or cholesterol, that contribute to heart disease, cancer, liver damage, and aging. He also has a popular blog.
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.
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.
On Day 4, I reached for a beef jerky stick from Epic. I simultaneously took a big bite while turning over the packaging to read the label. When I saw it on the ingredients list, I stopped mid-chew: "honey." I immediately spit the partially chewed jerky in my garbage can. Close one. After that, I always read the labels on my food twice before eating a morsel.
