The so-called Paleo diet is the latest eating fad.
As described by its advocates, the modern Paleo diet may or may not reflect our Stone Age ancestors' actual diets.
More importantly, the Paleo diets described by credible authors fit well with current nutrition-health findings.
Predictably, the diet's popularity has spawned a flood of books, but few come from seriously credentialed nutritionists.
Esther Blum, RD, MS is one clear exception ... and her scientific savvy really shows in Cavewomen Don't Get Fat: The Paleo Chic Diet for Rapid Results

About Esther Blum
Esther Blum, RD, MS, is a registered dietitian and expert nutrition advisor at Dr. Nicholas Perricone's flagship Manhattan skin care store.
Blum was voted “best nutritionist” by Manhattan Magazine, and has appeared on the Today Show, ABC-TV, and in Time Magazine, The Los Angeles Times, In Style, Martha Stewart Weddings, Bazaar, Self, Fitness, Marie Claire, and Cosmo.  
As Publishers Weekly wrote about Esther's first bestseller, “For a more compassionate, flexible and trustworthy guide, check out Eat, Drink and Be Gorgeous by registered dietician (and go-to nutrition expert) Esther Blum. Not only is Eat, Drink fun and funny, it's actually encouraging, sensible and written with the average person in mind.” 
Esther Blum invites you to visit for tips, free resources, and more.
Unlike most Paleo diet writers (and most dietitians), Esther Blum holds a Master of Science in Clinical Nutrition (from NYU), and is board-certified by the American College of Nutrition.
So don't mistake her easy, breezy writing style for a lack of substance.
Esther has a knack for helping people apply sound science to their everyday lives … in a warm, funny, friendly fashion.
Here's how she described her personal journey to the Paleo approach to eating:
“I have struggled with figuring out what to eat and what works best for my body. I am no different than you, but what set my life back on track was literally returning to my roots through Paleo eating.”
“It's high time we throw up our hands and admit that trying to lose weight the traditional way just doesn't work.”
“I discovered that if I follow a diet similar to the one my long-ago Paleolithic sisters ate, I can be lean, strong, sexy, and healthy. And you can be too.”
The Paleo Chic plan presented in Cavewomen Don't Get Fat curbs the excess of sugars, refined carbs, and omega-6-rich vegetable oils in the Standard American Diet, which promotes chronic inflammation,  heart disease, dementia, diabetes, cancer, allergies, and autoimmune disorders.
In the chapter titled Nutrition Benefits of the Paleo Chic Diet, she boils her plan down into the basics, upon which she elaborates later in the book:
  1. Eat plenty of high-quality lean proteins such as pastured poultry, grass-fed beef (cxlick to browse ours), and wild fish.
  2. Select your fats carefully. She advises cutting way back on omega-6-rich vegetables oils (corn, soy, safflower, sunflower, cottonseed) in favor of the long-chain omega-3s found only in fish. Moderate amounts of saturated fats are fine, and even beneficial. Avoid hydrogenated oils and their harmful trans fats.
  3. Get your carbs from fiber- and nutrient-dense fruits and vegetables, rather than from sugars or grains, and other “modern” starches.
  4. Favor fermented dairy – cheese, yogurt, kefir – over milk.
In accordance with point #3, her Paleo Chic plan's initial 30-day phase “hits the metabolic reset button by clearing out extra sugar and extra carbs.”
And on page 36 of Cavewomen Don't Get Fat, she makes her stand on seafood: 
“Eat wild fish. Wild Alaskan salmon is my favorite. A 6-ouce serving has almost 700 IU of vitamin D and 2 teaspoons [of] fish oil. The omega-3 fats found in fish oil boost and sustain serotonin levels in the brain and reduce vascular inflammation associated with heart disease. Aim to eat cold-water fatty fish such as salmon, herring, mackerel, Chilean sea bass, trout, and anchovies at least three times per week.” [Editor's note: tuna, sablefish, and sardines also belong on that list.]
As well as foods that promote weight gain, Esther identifies the “obesogenic” chemicals around us that promote weight gain by messing with our hormones, and tells how to avoid them.
Cavewomen Don't Get Fat also features more than 100 quick recipes for breakfast, lunch, dinner, and Paleo-friendly desserts, to help you put her plan into action.
As you'd expect, they include several fast recipes for wild seafood … especially fresh, canned, and smoked salmon.
Full disclosure: Esther Blum recommends as a source of wild salmon and seafood on pages 81 (“Sustenance from the Sea”) and 268 (Recommended Products) of Cavewomen Don't Get Fat.
We met her through Dr. Perricone – a longtime Vital Choice supporter – whose flagship store has featured our canned and smoked wild Alaskan salmon, in line with his strong advice to eat plenty of wild salmon and other fatty, omega-3-rich wild fish.
