A number of randomized clinical trials have compared the paleo diet to other eating plans, such as the Mediterranean Diet or the Diabetes Diet. Overall, these trials suggest that a paleo diet may provide some benefits when compared with diets of fruits, vegetables, lean meats, whole grains, legumes and low-fat dairy products. These benefits may include:
I had the same effect but I used the same pan. The issue I had was the egg whites. I beat them with a mixer for 2 minutes with the cream of tartar and still couldn’t get them whipped. I’d say they were half whipped. I gave up and put them in the loan pan anyway. The bread looked the same and tasted great but it was somewhat spongy. I’m wondering if the egg whites really wouldn’t whip because I didn’t realize they had to be room temp. The bread is great but it won’t hold up for sandwiches. Any tips on egg whipping? I felt egg defeated today!
This is the best keto bread I have ever made! By far! My bread was a little flat, but I think my baking powder needs to be replaced. I did make two substitutions with this recipe. I replaced egg whites with whole eggs, and ghee with coconut oil. Everything else, I already had on hand. I will definitely make this again and play with it a little. Really delicious bread.
It sounds like Weevils. They make cobwebs in flour and flour baked goods and were the bane of the Sailors on long voyages for centuries. I have found using a large lidded container, plastic, metal, ceramic or whatever you have, and sprinkling Diatomaceous Earth inside and round the lid keeps all my different flours healthy and hygienic. Diatomaceous Earth is a natural silica like powder which can even be taken internally, and totally dehydrates any bugs etc leaving them very dead. I use it in my chicken run and even on my cats and in their food. It keeps them healthy and parasite free. It is a sustainable, non chemical product – just check its Food grade before buying it. I guess they seell it in the US. It’s used a lot here in the UK.
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.
Of course Wikipedia has a page on the Paleolithic Diet. It is quite thorough. It also isn't clear about the lean/fatty meat debate between the followers of Loren Cordain and a slew of others, and pushes lean meat. It is weak on the variations of the diet. Then it restricts fermented beverages. Even butterflies eat fermented fruit. Why wouldn't our paleo ancestors also?

Hi Nancy, this recipe does not make enough batter to properly fill a full sized loaf pan. So, if you use the recommended size baking pan, the bread will be the proper height. If you use a pan that is bigger than the one I used, your bread will rise, but it won’t fill the pan to the right height. Here’s an example that might help –if you place 1/2 cup of water in a 1/2 measuring cup it will be 100% full to the top of the cup. If you put the same 1/2 cup of water in a 1 cup measuring cup it will only fill it 50% and will only be 1/2 full in height. That’s why a loaf pan that is too large doesn’t work for this recipe when it comes to the height of the loaf :-)
I don’t have dietary issues and do not adhere to a strict paleo diet. I do, however, have a raging sweet tooth that I try to keep in check by eating a low glycemic diet day to day, and limit high glycemic foods to those times when I am deliberately treating myself to “sweets”. This bread is more the texture of “quick bread” (like banana, or zucchini), which was a surprise. Its very tasty and satisfying, almost rich. This bread will be a good delivery system for peanut butter and bananas or soft boiled eggs.
For those who were considering ordering Paleo bread from the Julian Bakery online, just a word of caution: beware! The bad reviews are really true, and I’m not one who usually does any online reviews. I have ordered both the almond and the coconut breads for awhile. I am not sure what to make of the taste of them, but the almond is definitely a no-go for me. The coconut was palatable, if you chug down some liquid with it and pretend you’re not about to choke! It’s gagging, tasteless, and soggy-at-times bread, but I guess I was desperate for a slice, truly desperate to think it was edible.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soyfoods, and peanuts. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.
I’ve been working on this Paleo Bread recipe for several months and have tested it a couple of dozen times. In fact, every time I create a recipe I test each and every ingredient addition or subtraction. That’s why I think it’s kinda funny when people leave comments below recipes (or on Instagram) asking how such and such ingredient substitution will turn out.

I just made this today, and my husband, toddler, and I all loved it! We used ours for cheese and tomato sandwiches, and my husband managed to eat about half of the loaf before it even cooled. Like another person mentioned, I had to bake mine longer, but for me it was nearly twice as long (I’m at a relatively high altitude, maybe that’s why?). As yet another person said, it will now be a staple in our home too!


[…] Review: I tried my best to modify my mom’s stuffing recipe with paleo bread, but some things are not meant to be.  Stuffing is one of those things that need the real thing in order to taste authentic.  It wasn’t terrible, but if you want that REAL stuffing taste, you won’t find it here. The bread recipe on it’s own was not bad at all, check it out here! […]
I have admired your blog and recipes for a while now. But as a “Paleo” devotee and blogger I am motivated to compliment you on this particular post. The first sentence about gluten free not necessarily meaning healthy is so true and has kept me from trying a lot of gluten free products and recipes. But my kids often request some sort of gluten free bread (kinda funny that kids would consider getting bread a treat!) I can’t wait to try this recipe because the ingredients are really wholesome -truly “Paleo”.
Angie, I’m happy to hear you and your hubby enjoyed the taste, but sorry to hear the bread was flat! The egg whites don’t need to be whipped for this recipe, but I’ll try to help you troubleshoot…first I would check to make sure that your baking powder is fresh. Also, did you use the full cup of egg whites? Did you make any ingredient substitutions or adjustments? Did you use a 9 by 5-inch loaf pan? Did you cook it at 350F and is your oven properly calibrated? Did you bake it for the amount of time the recipe calls for? I hope this helps!
Hi Jodi, I haven’t tried that, but don’t think it would work well for this recipe. First, yeast needs sugar (for it to consume – it’s not typically in the end result), so you’d need to add that. But also, just with how we are making the bread fluffy with beaten egg whites, I don’t think yeast would work. If you want to try adding yeast to a low carb bread, I would do it with this low carb bread recipe instead.
This was my first foray into paleo breadmaking (and eating). DELICIOUS! I had to leave the room or else I would have eaten the whole loaf. I’m experimenting with recipes to try and find a GF sandwich bread that my kids will like. I’m going to make this again but will either use the coconut cream or use sweetened yogurt or add honey to make it a little sweeter. I’m also thinking about making it in a tin can so I can cut it into round slices.
Hi Valerie, so funny, I just got asked this question! 🙂 Here’s what I said, “…almond flour is a lot less absorbent than coconut flour (like A LOT). I know a few people have tried using oat flour with success, but I worry that almond flour would not be sufficient for absorbing the almond butter and creating a nice, firm texture. I’d recommend starting with about 3/4 cup almond flour, and experimenting as needed.” Hope this helps!

These paleo 7 layer bars make the PERFECT gift for your friends and family since they look amazing and can easily be packaged.  It now makes so much sense why I used to see these magical 7 layer bars everywhere during the holidays.  Plus, they’re easy to make and, now that we can make them vegan, paleo, and even clean eating, you can share with almost anyone!


Baking with almond flour can sometimes be tricky and not all brands give you the same results. Actually, the one you cited is my least favorite and usually makes baked goods sink in the middle, get very dense and also crumbly. I highly suggest you use one of the brands of blanched almond flour I recommend. My favorites are by Honeyville, Welbee’s and Nuts(.com). Here’s Welbee’s on Amazon for $23 for 2 LB http://amzn.to/1M5cDzG
Protein is a staple of the caveman diet- specifically options that are grass-fed, wild caught or organic, as these options are often from animals raised in environments that encourage natural behavior. And because our ancestors didn't just live off chicken and beef, they hunted a wide variety of meat, the more variety you can add to your proteins, the better!
This cornbread is cooked up southern style, but because it’s using ingredients that are Paleo friendly it clocks in as a low-carb food. Isn’t it nice to not have to worry about carbs, calories, fat grams, points, or any other silly thing they have you counting on other diet programs. With Paleo your focus is on using pure, wholesome, natural ingredients and eating until you feel satisfied. It’s about taking a philosophy towards food that is more in line with our body’s natural state of being, before we went and mucked things up with agriculture. This cornbread goes great with a bowl of Paleo chili.

It took me a few days to finally getting around to making these but I did because of your sloppy joe recipe you just posted. They are awesome!!! Next time I will make a double batch of buns! I used a muffin top pan for the buns and they came out perfect for tops and bottoms so I didn’t even have to split them. They bakes up really smooth and held together perfectly for wet sloppy joes! Thanks so much for developing and sharing your recipes. I am definitely becoming one of your biggest followers! Everything you make “works”!
Love, love, love! I make a double batch and freeze them with great results. I toast these rolls for all kinds of sandwiches including toasted with bacon, egg, avocado for breakfast. Recently I started sprinkling Trader Joe’s Everything but the Bagel Sesame Seasoning Blend on the tops before baking. Toasted with butter is a great substitute for bagels or hard rolls. Thank you Lexi for such a great recipe!
Hi John, You could possible try a hand mixer in a bowl instead of the food processor, but I haven’t tried it, so can’t vouch for the results. Most likely the bread would not be as tall because the mixer would completely deflate the first half of the egg whites when you add them to the batter. The second half should be folded so that part will be find. If you try with a bowl and hand mixer, let me know how that goes.
That is EXACTLY what I just started reading through the comments to find out! I’m not that successful a baker anyway, and we’ve lived in CO for the last three years and the altitude has killed all but the easiest recipes for me. And now I’ve been diagnosed with a condition requiring gluten-, dairy-, sugar-, and soy-free. I’m looking forward to trying this recipe!

Melted ice cream dripping down the side of your arm from a classic ice cream sandwich can really bring back some old childhood memories…along with a sugar rush, followed by an extreme crash. Instead, go for these Paleo cookie sandwiches that nix all the fake sugar. We choose the simple Paleo Vanilla Bean Ice Cream but there are two other delicious choices if you’re feeling like some extra flavor!


“All plants contain chlorogenic acid, mostly in the stems and leaves, but sunflowers also have it in the seeds. A spokeswoman for Red River Commodities says that SunButter does indeed turn cookies and other baked products green as they cool. The solution, she says, is to reduce the amount of baking soda or baking powder in your recipe by almost half, which balances the acidity of the ingredients and keeps them from changing color. Whether your cookies will rise adequately with half the leaven is a good question, but she says some people who have gotten in touch with the company say they don’t notice any difference. Adding a bit of lemon juice to your dough or batter can also help maintain expected colors. ”
WOW! This bread is amazing! I have Gestational Diabetes, and have been struggling with bread since it has been spiking my sugars. Normally I don’t each much of it, but I was just craving it today. So I made a loaf and it is delicious! I went through the comments because I only have a full size loaf pan, and did as someone else mentioned, increased the recipe by .5 (for the eggs did 8 eggs rather than 7), and it came out the perfect size and absolutely delicious. Looking forward to enjoying it the rest of the week. I used a glass full size loaf and cooked for 40 minutes at 350 degrees. I topped it with extra flax seeds because I too love the nutty flavor of flax.
OMG these are AMAZING!!! I’ve made them three times in the past week and my family eats them like crazy. We haven’t had “bread” since we went Paleo in June. (Not that we haven’t tried, but these are the real deal). I always double the recipe and they always turn out perfectly. I found a little loaf pan to make them in and now I have cute little loaves of bread. I love, love, love this recipe. One of my favorite things ever! Thank you.

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.

I would like to try this Paleo recipe as it really does look like a healthy one! We appreciate all your hard work “tweaking” these recipes to get them just right! However, I would like to comment that some of your recipe “supporters” live in Canada and we can’t get some of the brand named items you mention at times. Perhaps for this reason some have asked re substitutions. As an example, I made your Chocolate Prune Bars the other day but wasn’t sure about the NuNaturals Stevia. I didn’t know whether it was a powder or a liquid, and since we don’t have that brand here I took a “leap in the dark” and used SweetLeaf Vanilla Creme since there was vanilla in the recipe anyway. I’m sure yours turned out better than mine but I’m going to try again. Also, wasn’t sure whether the chocolate chips were semi-sweet or unsweetened, but just used what I had, which was bittersweet. I guess that item is pretty well a personal choice. Just thought I would let you know that we do have some different brand names in Canada which can sometimes confuse the issue.
I just wanted to say that I made this bread and it came out fantastic! I’m very pleased with it. It held together nicely and had a good taste. I felt it was also a great base for maybe some nut additions or raisin bread for a sweet twist. I’m definitely going to be playing around with this recipe. It was so EASY to put together too! Just perfect for a busy family trying to stay healthy and feel good. Thanks so much Elana!

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?


Hi Howard, You’re right that this bread doesn’t rise much – the volume comes mostly from whipping the egg whites. If the whites fell too much, the bread might not be tall enough. But even if they didn’t, it might still be shorter than some other tall bread loaves. Feel free to multiply the recipe by 1.5 if you prefer a taller loaf. I’m glad you liked the flavor and texture!
I made its latest version today and absolutely I love it. I like that it does not taste like almond or coconut it tastes like a bread. A verg good bread that it’s not harmful at least with recent knowledge of us because before it I thought whole meal bread is really good for us and I was very proud to my healthy breakfast oats, raw honey and seeds but then they figured out that oats are not harmless I am wondering what is the next thing that will be deleted from my diet:((
*Do NOT use an almond butter that you need to stir, as I did not have luck with it setting properly, and sticking to the coconut cream. I used Maranatha No-stir natural almond butter and highly recommend it! **You really only need about 2oz chocolate to cover the bars, but having some extra makes it SO much easier to get them covered evenly and quickly. The nutrition information reflects 2oz, but definitely use 3 to make it easier on yourself.

A friend made this bread with pecans or walnuts because she had no almonds. She sent me home a slice after church this last week. I did not think I missed bread…OH MY Goodness. It is SO light. I loved every bite.I am very strict paleo because of allergies and blood sugar issuses keeps me low carb Paleo. Thank you so much for the HARD work of your experimentation. Love you. Lynn


It took a month or so, but I finally decided to start playing around with adding a few other paleo-friendly starches, like arrowroot and tapioca. That’s what it took for me to come up with what I consider to be the perfect loaf. I had been holding out on adding other starches because I wanted to keep my ingredient list minimal, but really, these additions make all the difference in the end result of this bread.
The Paleo diet cuts out all grains, legumes, dairy and added sugar with the intent to get your body feeling good and your gut healthy. While a dessert that’s Paleo doesn’t justify indulging in a sweet treat every day, it does cut out any processed refined ingredients that are killing your waistline. Using natural ingredients like coconut sugar, coconut oil, and maple syrup (instead of white sugar) can have a major impact on your blood sugar spikes and reduce those continuous cravings that come along with them. Instead of going for those mysterious desserts, go back to a human diet and get your nutrition on with real food!
Ohhhh! Almond flour and coconut flour! I love it. I have made bread with just coconut flour, and love the texture, but find it too sweet. The almond flour bread I love the taste, but it’s a bit dry. This recipe sounds like a great match. I can’t wait to try it. Thanks for working so hard to find such amazing recipes and then sharing them with the world!
— HOW I WORK IT: I am 10 years into maintaining my 35 lb weight loss, and it continues to be a conscious effort. Right now the best way I am able to include Elana’s recipes into my post-weight-loss and weight-maintenance life is by following the gaps diet, which includes hearty soups as the basis for eating, filled in by some nut baked goods. Enjoy!
I cut the bread into thin slices and it is great toasted. I made a sandwich for my husband with bacon, lettuce and tomato and when I handed it to him he looked at me funny and after he took his first bite he asked me: “where did you buy this bread, can we eat bread now?” lol…. I told him I had made the bread with almond flour instead of wheat and he was thrilled.
Just made this bread tonight and I love the texture. I am still deciding on the taste. It reminds me of cornbread which isn’t a bad thing, necessarily. I think when I make an actual sandwich out of it I will not even notice the difference. Also thinking it could be good for a casserole of some sort. We also had your Chipotle Orange Chicken and that was a big hit! I am loving this site, a huge THANK YOU!

The NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
Diet has been an important part of our evolution—as it is for every species—and we have inherited many adaptations from our Paleo predecessors. Understanding how we evolved could, in principle, help us make smarter dietary choices today. But the logic behind the Paleo diet fails in several ways: by making apotheosis of one particular slice of our evolutionary history; by insisting that we are biologically identical to stone age humans; and by denying the benefits of some of our more modern methods of eating.
Hi, I made this bread a couple of days ago, and the flavor was Amazing!! A tad sweet, I may use less honey next time, but very very good. I separated the egg whites and blended with hand mixer until stiff peaks formed, and then folded them into the rest of the batter. Originally the bread came out high like I wanted, but then by the following day had condensed down and was a heavier bread like zucchini bread. Next time I may slice and freeze right away, and then take single pieces out to toast. This bread was so easy to slice, even into very thin pieces, which I was amazed at. Overall a great recipe. Would probably be good with dried cranberries or blueberries and black walnuts :) for a dessert bread. My grandma, who doesn’t normally eat paleo, LOVED this bread!! THank you for taking out the hard work for us in making great paleo recipes.

I’ve been on a Keto diet for 8 weeks now and haven’t eaten any bread. This recipe should come with a warning – extra willpower required! ‘Cool in the pan for 2 hours’. Are you kidding me? It smelled so delicious I had to have a slice still warm, with butter. It was delicious. Next time I’ll be good and follow the instructions. Can’t wait to try the others. Thank you Elana!
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.
Whether you follow a paleo diet or not, these recipes are the perfect bites of indulgence for your sweet tooth. I included a mix of cookies, muffins and bars packed with better-for-you ingredients (and plenty of dark chocolate) that you can look forward to after a long day. Why? Because I think you should treat yo’ self every day – however that may be. For me it’s usually something topped with my favorite nut butter and/or a drizzle of chocolate, and for you it might be a fluffy slice of banana bread. Take a scroll, pick your favorite, and treat yourself to something delicious today!

Hey Maya!! This is the 2nd recipe I’ve tried off your website and again I love it!! Turned out really well. I can have sandwiches again or a quick piece Of toast when I’m in a hurry to get out the door. I was skeptical about the xanthan gum since I tried a recipe using psyllium husk powder. I did not like it. I can’t taste the xanthan gum so I have no problem using it going forward. Thanks again for the recipe!!!

Paleo diets are based on a simple premise – if the cavemen didn’t eat it, you shouldn’t either. So long to refined sugar, dairy, legumes and grains (this is pre-agricultural revolution), and hello to meat, fish, poultry, fruits and veggies. The idea is that by eliminating modern-era foods like highly-processed carbs and dairy, you can avoid or control “diseases of civilization” like Type 2 diabetes and heart disease, and likely lose weight too. What you eat and how much depend on your goals or the specific program you’re on, if you choose to follow one. The high-protein diet is ranked poorly among U.S. News experts, who consider it too restrictive to be healthy or sustainable.


I finally had a chance to try this receipe yesterday. I liked the taste, but for some reason it did not rise very much. When I put all of the batter in the pan(yes, I used recommended pan), it filled only half of the pan, and after baking, it stayed almost at almost the same level. The baking soda was not old(bought 1 month ago). Does anyone know what I might have done wrong? I whisked the ingredients, instead of using food processer. Could it be a reason? Or was it because I used regular flax seed grounded by muself?
By latest count, about 800 Hiwi live in palm thatched huts in Colombia and Venezuela. In 1990 Ana Magdalena Hurtado and Kim Hill—now both at Arizona State University in Tempe—published a thorough study (pdf) of the Hiwi diet in the neotropical savannas of the Orinoco River basin in Southwestern Venezuela. Vast grasslands with belts of forest, these savannas receive plenty of rain between May and November. From January through March, however, precipitation is rare: the grasses shrivel, while lakes and lagoons evaporate. Fish trapped in shrinking pools of water are easy targets for caiman, capybaras and turtles. In turn, the desiccating lakes become prime hunting territory for the Hiwi. During the wet season, however, the Hiwi mainly hunt for animals in the forest, using bows and arrows.
The Paleo Solution: The Original Human Diet by Robb Wolf, a research biochemist. Readers will understand digestion, how protein, carbohydrate and fat influence hormones, and how this plays into fat loss, health or disease. They'll understand the significance of dietary fats whether the concern is performance, health, longevity, or making your fanny look good in a bikini. The book goes into how lifestyle factors such as sleep and stress influence the hormone cortisol. It gets into basic blood work and what things people should ask their doctor to include to better assess inflammation and health. It also includes a detailed 30-day meal plan and a beginner exercise program. The exercise program is geared to the beginner or someone who is quite de-conditioned but the nutritional info would be helpful for anyone regardless of background. The author's website is Robb Wolf. He likes to pass out the information via weekly podcasts. Here's a video Introduction to the book. And here is an excerpt from the book: How to Keep Feces Out of Your Bloodstream (or Lose 10 Pounds in 14 Days). The many Amazon reviews all rave about the book. Published September 14, 2010.
Some Paleo dieters emphasize that they never believed in one true caveman lifestyle or diet and that—in the fashion of Sisson's Blueprint—they use our evolutionary past to form guidelines, not scripture. That strategy seems reasonably solid at first, but quickly disintegrates. Even though researchers know enough to make some generalizations about human diets in the Paleolithic with reasonable certainty, the details remain murky. Exactly what proportions of meat and vegetables did different hominid species eat in the Paleolithic? It's not clear. Just how far back were our ancestors eating grains and dairy? Perhaps far earlier than we initially thought. What we can say for certain is that in the Paleolithic, the human diet varied immensely by geography, season and opportunity. "We now know that humans have evolved not to subsist on a single, Paleolithic diet but to be flexible eaters, an insight that has important implications for the current debate over what people today should eat in order to be healthy," anthropologist William Leonard of Northwestern University wrote in Scientific American in 2002.
