I had an awful experience with the recommended Magic Line loaf pan. The uncoated “natural” aluminum this pan is made of can dissolve and leach into food that contains acidic ingredients. I’ve been using anodized aluminum cookware for years to prevent this from happening, and I should have known better, but I ordered the pan from Amazon anyway because I wanted the little square slices.
For example, the University of Lund found that a Paleolithic diet improves glucose tolerance more than a Mediterranean-like diet in 29 individuals with ischemic heart disease. The University of Lund also found, in a separate study, that the Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in 13 patients with type 2 diabetes in a three-month trial. Another study, by the Karolinska Institute in Huddinge, Sweden, found that eating short-term Paleolithic or hunter-gatherer diets to prevent cardiovascular diseases showed some favorable effects, but they noted that further studies were warranted. 
Bailey, We’re so happy to hear you enjoyed this recipe! Regarding having bread fall, did you cook it for the full amount of time the recipe calls for, and did you cover the top with foil for the last 15 minutes? If so, there might be an issue with your oven’s calibration (you can get an inexpensive oven thermometer to check this). Another tip is to let your eggs come to room temperature first. Another factor is the altitude at which you’re baking; if you’re at high altitude, you might need to slightly adjust the oven temperature and bake time. The other thing to remember is that there will usually be a little bit of fall to most keto breads (in fact, every keto bread we’ve ever made) because keto flours lack gluten and are naturally quite dense; however, you can see in the photos, we still got a good rise on this loaf. I hope these tips help!
It’s easy to find more guidance online, but a book also makes a handy reference. "The Paleo Diet," for example, outlines basic Paleo principles and offers three “levels” that allow for different degrees of cheating – three “open meals” per week on the “entry level” plan, two on “maintenance” and just one on “maximal.” Depending on the level, you might also get “transitional” condiments (low-fat dressing and salsa) and drinks (coffee, beer or wine in moderation) to wash down the meat and plants. You can use the levels as you like. Start with the first and move gradually to the more restrictive – or just stay put. For more dramatic changes, head right to the third.

Made this yesterday and it looked/tasted beautiful! Did not do anything special (whipping the white, creaming the butter, etc) .. just folded gently and it was just a beautiful golden color. I topped it with sesame seeds because the flax seeds had already been put away. I put the dough into two mini-loaf pans and they fit perfectly. Perfect way to get my bread cravings with gest. diabetes and got two thumbs up from my diabetic dad, too, who eventually stole my other loaf! Will be making again and again. Thank you!

Hahaha! Demeter – I so so know what you mean about that almond butter grease that gets EVERYWHERE and, like you said, refuses”to let go of its dish territory” I still love making my own almond butter (mostly cos it doesn’t cost me a kidney and an arm) when I have the time – lately time has been in short supply for me – also in short supply are treats as decadent as these! You sure are a good almond-butter-making-maniac-sister to keep your sisters supplied with treats like these bars – though in the unlikely event that you end up with more of these bars than they are willing to take off your hands – well, I’d be delighted to help out! Just saying 😉
Thank you so much! I didn’t have any flax for the first couple of batches, so subbed extra almond flour, then made it my bread machine and it was a hit. But for this batch, I doubled to make two loaves using the ground golden flax and baked it in the oven, and it was even better!!! My son who has celiacs loves it. This is a godsend with school lunches coming up again.
Regardless of people pleasing, this nut and seed paleo bread quickly became a staple in our house and a new FAVORITE!  I made a few loaves batch and froze one loaf.  Just one loaf of this paleo bread made about a week worth of sandwiches plus breakfast toast. Heck ya!  If you follow me on snapchat, you will know this. I made the kiwi (aka my husband) all his sandwiches in one week so he wouldn’t forget to eat! Who does that?
Like a lot of others, mine didn’t rise as much as I had hoped, so the crumb is a bit more dense. Next time, I’ll give it longer than an hour and see if that helps. My loaf pan is also a bit bigger, so I think I’ll do 1.5 times the recipe next time for a larger slice of bread as mine was very short and squat, lol. Overall though, I’m thrilled. This is by far the best grain-free bread I’ve ever tasted!

thanks for the reply, but im still confused. the arrowroot you have pictured at the bottom of the recipe is the “flour” not the powder. I used the powder. however, it was hard to find and the only bottle of it that I could find was short of the 1/2 cup required in the recipe. I see you can buy larger quantities of the powder on-line. I added a TBSP of regular baking powder to make up for the short arrowroot powder. It came out pretty good!
In his 1988 book "The Paleolithic Prescription," Eaton and his co-authors argued that humans are ill-suited to modern diets because the large part of a human's genetic makeup was established thousands of years ago in pre-agricultural societies. Eaton and other advocates of the Paleo diet believe that many modern diseases are a result of today's eating habits.
NeanderThin: Eat Like a Caveman to Achieve a Lean, Strong, Healthy Body (Hardcover) by Ray Audette, with Troy Gilchrist, was one of the early paleo diet authors. His home page NeanderThin [now restored from archive.org] has a diet based on the ideas of paleolithic nutrition. The diet can be followed as a low-carb, moderate or high carb diet, depending upon whether and how much fruit is used. You can read up through page 19 of the book at Google Books. The original press release from 1999. [The webmaster has an extra copy with the author's signature for sale. It has the original lime-purple cover. Pristine new condition. $60 (shipping included).

Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them.[30] Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total age of 54.[31] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total age of 64 years.[32][33] That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."[34]
These are AMAZING! I have celiac and was diagnosed about 4 months ago. It’s been very difficult and bread is what I miss most. Unfortunately, GF bread is not very tasty-i’ve tried a number of brands and have tried making my own. I love the simplicity of the recipe as well. Thank you for creating amazing clean recipes, your cookie bars are also fabulous!
